The quiet man of GRC

GRC? It’s short for the TT Chang Genetic Resources Center at the International Rice Research Institute (IRRI) in the Philippines, which I had the privilege to lead between July 1991 and April 2001. I’m not sure if GRC is an organizational unit at IRRI anymore having just checked IRRI’s organizational structure dated April 2020.

However, GRC is/was the home of the International Rice Genebank at IRRI, the largest of its kind globally for rice. It safely conserves more than 130,000 samples (known as accessions) of cultivated and wild rice species from around the world and, as the most genetically-diverse collection of rice anywhere, it is the foundation for food security in many countries, especially in Asia. Rice breeders have dipped into this valuable resource for almost six decades since IRRI was founded in 1960 and the first germplasm samples brought to Los Baños by my predecessor, Dr TT Chang.

Renato ‘Ato’ Reaño

Anyway, this post is not about me or Dr Chang, but about someone who surely was the quiet man of GRC. Who is this low-key individual?

Why, Renato Reaño of course, known to one and all as ‘Ato’.

Not long after I joined IRRI, it became clear to me that Ato should become my right-hand man for managing all the genebank field operations, from multiplication and rejuvenation of seed samples, as well as establishing and looking after field plots for germplasm characterization (although the actual scoring of the materials was the responsibility for a few years of another colleague, Tom Clemeno, who passed away in 2015).

So, once I’d made an analysis of how the genebank was being managed when I took the helm in 1991, and decided on changes I deemed necessary (not universally accepted by all genebank in the first instance after several decades of working under Dr Chang), I asked Ato to take on the role of Field Operations Manager (although at that time he was officially still only a Research Assistant).

Ato retired from IRRI in March this years after more than 36 years of loyal—and very productive—service to the institute. Over the years, and as his confidence grew, taking on more responsibilities, Ato was promoted to new levels in the IRRI hierarchy, and retired as a Senior Associate Scientist.

Along the way he was elected to lead the IRRI employees association (an excellent indication of the esteem in which his colleagues held him), and he was also elected President of the Crop Science Society of the Philippines (CSSP) for 2006-2007.


Ato helped develop and implement many necessary changes to field operations. What is often not fully appreciated that for the long-term conservation of seeds in a genebank, what happens in the field during the growing season and how seeds are handled through the drying process are as important—if not more so in some respects—than the actual storage conditions. Dr Fiona Hay, a seed physiologist who was hired after I’d passed the GRC baton to my successor Dr Ruaraidh Sackville Hamilton in 2002, studied how the drying of seeds could be improved further, and Ato’s role in managing the rice germplasm in the field and the drying after harvest was pivotal. I’ve written about those aspects of rice germplasm management in an August 2015 post.

Ato made the field operations look straightforward. Nothing could be further from the truth. He had to handle thousands of seed samples each planting season, nurturing each one, ensuring there were no mix-ups.

He had a great rapport with his staff. Here he is with some of them in 2017 after they had finished the harvest of more than 4000 samples, and dried them successfully using the new approach that I referred to in the August 2015 post above.

Each season (there being two in Los Baños, wet and dry) Ato took responsibility for growing thousands of seed samples, some for the first time after they had been acquired by the genebank, others for routine regeneration if seed viability had declined or seed stocks were running low, or for characterization of the different rices for a whole series of traits, such as days to flowering, plant height, color of grains, and the like.

But to have a better appreciation of Ato’s work in the field and how that contributed to the work of the genebank, just watch this segment, 2:04 – 4:29 minutes in the video below to see for yourselves.

Ato remained the quiet man of GRC during the years I was at the helm, but he constantly grew in confidence, taking his first overseas trip on behalf of the genebank to present a paper at ICRISAT in Hyderabad, India in 1995, and eventually being recognised by his peers and elected to the roles I mentioned earlier.

I also relied on Ato to help me interact with GRC staff. If I became aware of a staff ‘situation’ developing (perhaps an unease I could detect as I made my daily visits to every part of the genebank), it would have been difficult for me as Head of GRC, and as a non-Filipino who didn’t speak Tagalog, to easily get to the bottom of things. Then I would ask Ato to help find out what was going on, deal with it if he could, and only elevate issues to me that needed my intervention. This relationship worked well, and I was very grateful to Ato for the management support he provided in this respect.

Thanks for everything that you did, Ato. Your contributions to the long-term conservation of rice genetic resources will long be remembered and appreciated.

With Ato’s retirement, there’s just one of ‘my’ staff left. Genebank Manager Pola de Guzman will also retire later this year. It will finally be the end of the Chang-Jackson-Sackville Hamilton era.


 

Science publications that influenced my choice of career . . .

I’m sure, like me, many scientists have a few publications that they treasure. No, I’m not referring to any which they themselves authored; rather, publications that made them sit up and pay attention, so to speak. And, in doing so, particularly stimulated their interest and perhaps even guided their own scientific careers subsequently.

I’ve now been retired for ten years, but I still look back to how I got started in the world of plant genetic resources fifty years ago, and some of the scientific publications that pointed me in that direction. Let me backup a little and explain how this came about.

In 1967, I was accepted on to a BSc degree course at the University of Southampton (on England’s south coast) to study environmental botany and geography. I’ve written elsewhere about the three very happy years I spent in Southampton until graduation in July 1970.

The core of my degree course, particularly in my third or senior year, was a two semester ecology module taught in the Botany department, and different aspects of physical geography (such as geomorphology, biogeography, and climatology) in the Geography department. But I also took several shorter elective modules in Botany, including plant speciation, plant breeding, and population genetics. This latter course was taught by one of the pioneers in this field, Vice Chancellor Professor Sir Kenneth Mather who came to Southampton from the University of Birmingham (where he had been head of the Department of Genetics). He claimed (probably with some justification) that he was the only teaching Vice Chancellor at that time in the UK.

Joyce Lambert

We were a small group of only six or so ecology students, and this module was taught by quantitative ecologist Dr Joyce Lambert (who was also my personal tutor). All of us were required to submit an extended essay of 4-5000 words on an ‘ecological topic’ of our choice. It goes without saying that Joyce hinted she would prefer essays about her interest, namely the application of numerical methods to study vegetation landscapes.

I did not heed Joyce’s ‘advice’; I guess she was not best pleased. Instead, and with encouragement from genetics lecturer Dr Joe Smartt, I chose to explore the relationship between ecology, genetics, and taxonomy (the related fields of ecological genetics and experimental taxonomy) in an essay about the concept of ‘ecotypes’. Simply put, an ecotype is a distinct form or race of a plant occupying a particular habitat.

So that was my aim. What would be my entry point? And which literature would be most useful for my purpose?

From the 1920s onwards, several botanists (Göte Turesson in Sweden, JW Gregor in Scotland, and three staff at the Carnegie Institute of Washington in Stanford: geneticist Jens Clausen, physiologist William Hiesey, and taxonomist David Keck) had studied the variation of species (genetically, physiologically, and taxonomically) in relation to their environments, and the role of natural selection on plant adaptation. There was a wealth of literature to delve into. But where to begin?

Jack Heslop-Harrison

I was fortunate that, just a few years earlier, Professor Jack Heslop-Harrison (then Mason Professor of Botany at the University of Birmingham) published an important review paper about what became for me a fascinating branch of botanical science, the study of variation within species in relation to environment.

Forty years of genecology, published in Advances in Ecological Research in 1964 (Vol. 2: 159-247) was, for me, one of those formative publications. Not only was the review thoroughly comprehensive in its coverage, but had the added quality of being extremely well written. It has stood the test of time. Yet, it would be interesting to bring it up to date, introducing all the latest evidence based on molecular biology and genomics.

When I contacted Heslop-Harrison’s son ‘Pat’ (who is Professor of Plant Cell Biology and Molecular Cytogenetics at the University of Leicester) to request a copy of his father’s paper (I’d ‘lost’ the copy I once had) he told me that he began writing a review 100 years of genecology, but had never completed it.

He did make this interesting comment: When I started on a ‘100 years’ update, I was taken that some parts [of ‘Forty years of genecology’] sounded remarkably old-fashioned, while other parts could fit unchanged in a strong grant application made today. But how the combination of molecular/marker studies and modelling has really allowed genecology to take its rightful place in biology.

Immersing myself in the various concepts of ‘ecotype’, ‘clines’, and ‘infraspecific variation’ among many others, Heslop-Harrison’s review not only provided me with the impetus to fulfil a pressing course assignment, but subconsciously perhaps helped me make some decisions about a future career. I guess this was the first time I became really enthusiastic about any botanical sub-discipline. Later on, when I began working in the area of conservation and use of plant genetic resources, the study of variation patterns and adaptation in crop species and their wild relatives became an important focus of what I set out to achieve. In fact, understanding the nature of crop plant variation—and how to use it—is one of the fundamental concepts underpinning the value of plant genetic resources.

No study of variation in plant species would be complete, even today I believe, without reference to the pioneering work of Clausen, Keck, and Hiesey in California over several decades from the 1930s. Their work had been highlighted, of course, in Heslop-Harrison’s review. I went back to their original papers*.

L-R: Jens Clausen (cytology and genetics), William Hiesey (physiology), and David Keck (taxonomy/botany)

And what an eye-opener they were: a classic set of papers, published between 1934 and 1958, describing experimental studies on the nature of species that really caught my attention, and to which I still return from time to time.

While others, like Turesson and Gregor, had also studied plant variation experimentally, their work was not on the same scale that Clausen and his colleagues achieved across central California, from the coast to the high Sierra Nevada.

Working with a range of species, they collected samples from different populations of each across this Californian transect and, using a reciprocal transplant approach, grew samples at experimental gardens on the coast at Stanford and at different altitudes in the mountains, at Mather and Timberline. So, for example, samples collected from coastal sites were grown at the high altitude garden, and vice versa and all combinations in between. Even the same species looked different under different environments, in terms of plant stature or days to flowering, for example, being just two of the many traits they studied. They were interested if these traits would persist when grown in another environment. Here is an example from yarrow or Achillea.

Clausen, J, DD Keck and WM Hiesey, 1948. Experimental studies on the nature of species. III: Environmental responses of climatic races of Achillea. Publication 581. Washington, D.C.: Carnegie Institution of Washington.

They studied how well plants from one environment thrived in another, identifying the adaptations that enabled them to survive, and understanding both the genetic and physiological basis for adaptation, while recognising some of the variants taxonomically, if warranted. Many were simply locally-adapted populations, or ecotypes. Just a beautiful and competent piece of science.

Anyway, come the summer of 1970 and having just graduated, I still wasn’t sure what I’d be doing or where. I’d been accepted on to the MSc course on Conservation and Utilization of Plant Genetic Resources at the University of Birmingham to begin in September. But while I had a guaranteed place, there was no funding. And without a studentship there was no way I could support myself and pay tuition fees.

That all changed at the beginning of August or thereabouts. I had a phone call from Professor Jack Hawkes, who was Mason Professor of Botany (succeeding Heslop-Harrison) and the MSc course director, letting me know he’d found some funds to support my studies. It was wonderful news, and I immediately began to make plans to move to Birmingham in mid-September.

There was one important thing Jack asked me to do: purchase a copy of a book that had just been published, and try and work my way through it before I landed up in Birmingham.

This book, Genetic Resources in Plants – their Exploration and Conservation, was more than an eye opener as far as I was concerned. It was as if the scales fell from my eyes. What a revelation!

The book was dedicated to Nikolai Ivanovich Vavilov. Until then I’d never heard of this eminent Russian geneticist, the ‘Father of Plant Genetic Resources’, who subsequently became something of a scientific hero of mine.

Edited by wheat breeder Sir Otto Frankel and FAO scientist Dr Erna Bennett, both pioneers of the 1960s genetic resources movement, this book was essential reading for anyone entering the new field of conservation and use of plant genetic resources.

Sir Otto Frankel and Erna Bennett

It emerged from a technical conference held at FAO headquarters in Rome on 18-26 September 1967, and comprised 44 chapters penned by many if not most of the leading lights then in genetic conservation and crop and forestry specialists from around the world. As Sir Otto wrote in the preface, the book attempts to define and develop the principles underlying the various stages of exploration, conservation and utilization. Its usefulness will depend on the degree to which it succeeds in illuminating practical problems, rather than offering prescriptions or instructions.

In the course of my own entry into the world of plant genetic resources, I came to meet and become friends with several of the contributors.

The six sections covered topics in: (1) Biological background (the nature of crop diversity, centers of origin, taxonomy); (2) Tactics of exploration and collection; (3) Examples of exploration (crops and forestry); (4) Evaluation and utilization; (5) Documentation, records and retrieval; and (6) Conservation.

It became something of a ‘bible’ for me, and even today, I dip into its many chapters to refresh some of my ideas. Yes, the world of conservation and use of plant genetic resources has moved on significantly since its publication 50 years ago. Just think of the remarkable advances in molecular biology and genomics that nowadays open up a whole new dimension to our understanding of variation among important crop species and their wild relatives. And the impressive progress in computing for both data analysis as well as data management for crop germplasm collections. Fifty years ago, many things that we consider routine today were then but a pipe dream, if they were even on someone’s intellectual horizon.

I really do believe that anyone contemplating a career in plant genetic conservation as I was, 50 years ago, would benefit from delving into Frankel and Bennett, not only to appreciate how the genetic resources movement started in the 1960s, but also just how we have come in the five decades since.

Potatoes or rice?

I graduated in July 1970 from the University of Southampton (a university on England’s south coast) with a BSc Hons degree in botany and geography. ‘Environmental botany’ actually, whatever that meant. The powers that be changed the degree title half way through my final (i.e. senior) year.

Anyway, there I was with my degree, and not sure what the future held in store. It was however the beginning of a fruitful 40 year career in international agricultural research and academia at three institutions over three continents, in a number of roles: research scientist, principal investigator (PI), program leader, teacher, and senior research manager, working primarily on potatoes (Solanum tuberosum) and rice (Oryza sativa), with diversions into some legume species such as the grasspea, an edible form of Lathyrus.

Potatoes on the lower slopes of the Irazu volcano in Costa Rica, and rice in Bhutan

I spent the 1970s in South and Central America with the International Potato Center (CIP), the 1980s at the University of Birmingham as a Lecturer in the School of Biological Sciences (Plant Biology), and almost 19 years from July 1991 (until my retirement on 30 April 2010) at the International Rice Research Institute (IRRI) in the Philippines¹.

I divided my research time during those 40 years more or less equally between potatoes and rice (not counting the legume ‘diversions’), and over a range of disciplines: biosystematics and pre-breeding, genetic conservation, crop agronomy and production, plant pathology, plant breeding, and biotechnology. I was a bit of a ‘jack-of-all-trades’, getting involved when and where needs must.

However, I haven’t been a ‘hands-on’ researcher since the late 1970s. At both Birmingham and IRRI, I had active research teams, with some working towards their MSc or PhD, others as full time researchers. You can see our research output over many years in this list of publications.

Richard Sawyer

Very early on in my career I became involved in research management at one level or another. Having completed my PhD at Birmingham in December 1975 (and just turned 27), CIP’s Director General Richard Sawyer asked me to set up a research program in Costa Rica. I moved there in April 1976 and stayed there until November 1980.


In these Covid-19 lockdown days, I’m having ample time to reflect on times past. And today, 30 April, it’s exactly 10 years since I retired.

Just recently there was a Twitter exchange between some of my friends about the focus of their research, and the species they had most enjoyed working on.

And that got me thinking. If I had to choose between potatoes and rice, which one would it be? A hard decision. Even harder, perhaps, is the role I most enjoyed (or gave me the most satisfaction) or, from another perspective, in which I felt I’d accomplished most. I’m not even going to hazard a comparison between living and working in Peru (and Costa Rica) versus the Philippines. However, Peru has the majesty of its mountain landscapes and its incredible cultural history and archaeological record (notwithstanding I’d had an ambition from a small boy to visit Peru one day). Costa Rica has its incredible natural world, a real biodiversity hotspot, especially for the brilliant bird life. And the Philippines I’ll always remember for all wonderful, smiling faces of hard-working Filipinos.

And the scuba diving, of course.

Anyway, back to potatoes and rice. Both are vitally important for world food security. The potato is, by far, the world’s most important ‘root’ crop (it’s actually a tuber, a modified underground stem), by tonnage at least, and grown worldwide. Rice is the world’s most important crop. Period! Most rice is grown and consumed in Asia. It feeds more people on a daily basis, half the world’s population, than any other staple. Nothing comes close, except wheat or maize perhaps, but much of those grains is processed into other products (bread and pasta) or fed to animals. Rice is consumed directly as the grain.


Just 24 when I joined CIP as a taxonomist in January 1973, one of my main responsibilities was to collect potato varieties in various parts of the Peruvian Andes to add to the growing germplasm collection of native varieties and wild species. I made three trips during my three years in Peru: in May 1973 to the departments of Ancash and La Libertad (with my colleague, Zósimo Huamán); in May 1974 to Cajamarca (accompanied by my driver Octavio); and in January/February 1974 to Cuyo-Cuyo in Puno and near Cuzco, with University of St Andrews lecturer, Dr Peter Gibbs.

Top: with Octavio in Cajamarca, checking potato varieties with a farmer. Bottom: ready for the field, near Cuzco.

My own biosystematics/pre-breeding PhD research on potatoes looked at the breeding relationships between cultivated forms with different chromosome numbers (multiples of 12) that don’t naturally intercross freely, as well as diversity within one form with 36 chromosomes, Solanum x chaucha. In the image below, some of that diversity is shown, as well as examples of how we made crosses (pollinations) between different varieties, using the so-called ‘cut stem method’ in bottles.

Several PhD students of mine at Birmingham studied resistance to pests and diseases in the myriad of more than 100 wild species of potato that are found from the southern USA to southern Chile. We even looked at the possibility of protoplast fusion (essentially fusion of ‘naked’ cells) between different species, but not successfully.

I developed a range of biosystematics projects when taking over leadership of the International Rice Genebank at IRRI, publishing extensively about the relationships among the handful (about 20 or so) wild rice species and cultivated rice. One of the genebank staff, Elizabeth Ma. ‘Yvette’ Naredo (pointing in the image below) completed her MS degree under my supervision.

Although this research had a ‘taxonomic’ focus in one sense (figuring out the limits of species to one another), it also had the practical focus of demonstrating how easily species might be used in plant breeding, according to their breeding relationships, based on the genepool concept of Harlan and de Wet, 1971 [1], illustrated diagrammatically below.


When I transferred to Costa Rica in 1976, I was asked to look into the possibility of growing potatoes under hot, humid conditions. At that time CIP was looking to expand potato production into areas and regions not normally associated with potato cultivation. One of the things I did learn was how to grow a crop of potatoes.

I was based in Turrialba (at the regional institute CATIE), at around 650 masl, with an average temperature of around 23°C (as high as 30°C and never much lower than about 15°C; annual rainfall averages more than 2800 mm). Although we did identify several varieties that could thrive under these conditions, particularly during the cooler months of the year, we actually faced a more insidious problem, and one that kept me busy throughout my time in Costa Rica.

Shortly after we planted the first field trials on CATIE’s experiment station, we noticed that some plants were showing signs of wilting but we didn’t know the cause.

With my research assistant Jorge Aguilar checking on wilted plants in one of the field trials.

Luis Carlos González

Fortunately, I established a very good relationship with Dr Luis Carlos González Umaña, a plant pathologist in the University of Costa Rica, who quickly identified the culprit: a bacterium then known as Pseudomonas solanacearum (now Ralstonia solanacearum) that causes the disease known as bacterial wilt.

I spent over three years looking into several ways of controlling bacterial wilt that affects potato production in many parts of the world. An account of that work was one of the first posts I published in this blog way back in 2012.

The other aspect of potato production which gave me great satisfaction is the work that my colleague and dear friend Jim Bryan and I did on rapid multiplication systems for seed potatoes.

Being a vegetatively-propagated crop, potatoes are affected by many diseases. Beginning with healthy stock is essential. The multiplication rate with potatoes is low compared to crops that reproduce through seeds, like rice and wheat. In order to bulk up varieties quickly, we developed a set of multiplication techniques that have revolutionised potato seed production systems ever since around the world.

AS CIP’s Regional Representative for Mexico, Central America, and the Caribbean (known as CIP’s Region II), I also contributed to various potato production training courses held each year in Mexico. But one of our signature achievements was the launch of a six nation research network or consortium in 1978, known as PRECODEPA (Programa REgional COoperativo DE PApa), one of the first among the CGIAR centers. It was funded by the Swiss Government.

Shortly after I left Costa Rica in November 1980, heading back to Lima (and unsure where my next posting would be) PRECODEPA was well-established, and leadership was assumed by the head of one of the national potato program members of the network. PRECODEPA expanded to include more countries in the region (in Spanish, French, and English), and was supported continually by the Swiss for more than 25 years. I have written here about how PRECODEPA was founded and what it achieved in the early years.

I resigned from CIP in March 1981 and returned to the UK, spending a decade teaching at the University of Birmingham.


Did I enjoy my time at Birmingham? I have mixed feelings.

I had quite a heavy teaching load, and took on several administrative roles, becoming Chair of the Biological Sciences Second Year Common Course (to which I contributed a module of about six lectures on agricultural ecosystems). I had no first teaching commitments whatsoever, thank goodness. I taught a second year module with my colleague Richard Lester on flowering plant taxonomy, contributing lectures about understanding species relationships through experimentation.

Brian Ford-Lloyd

With my close friend and colleague Dr Brian Ford-Lloyd (later Professor), I taught a final year module on plant genetic resources, the most enjoyable component of my undergraduate teaching.

One aspect of my undergraduate responsibilities that I really did enjoy (and took seriously, I believe—and recently confirmed by a former tutee!) was the role of personal tutor to 1st, 2nd and 3rd year students. I would meet with them about once a week to discuss their work, give advice, set assignments, and generally be a sounding board for any issues they wanted to raise with me. My door was always open.

Most of my teaching—on crop diversity and evolution, germplasm collecting, agricultural systems, among others—was a contribution to the one year (and international) MSc Course on Conservation and Utilization of Plant Genetic Resources on which I had studied a decade earlier. In my travels around the world after I joined IRRI in 1991, I would often bump into my former students, and several also contributed to a major rice biodiversity project that I managed for five years from 1995. I’m still in contact with some of those students, some of whom have found me through this blog. And I’m still in contact with two of my classmates from 1970-71.

Research on potatoes during the 1980s at Birmingham was not straightforward. On the one hand I would have liked to continue the work on wild species that had been the focus of Professor Jack Hawkes’ research over many decades.

With Jack Hawkes, collecting Solanum multidissectum in the central Andes north of Lima in early 1981 just before I left CIP to return to the UK. This was the only time I collected with Hawkes. What knowledge he had!

He had built up an important collection of wild species that he collected throughout the Americas. I was unable to attract much funding to support any research projects. It wasn’t a research council priority. Furthermore, there were restrictions on how we could grow these species, because of strict quarantine regulations. In the end I decided that the Hawkes Collection would be better housed in Scotland at the Commonwealth Potato Collection (or CPC, that had been set up after the Empire Potato Collecting Expedition in 1938-39 in which Jack participated). In 1987, the Hawkes Collection was acquired by the CPC and remains there to this day.

Dave Downing was the department technician who looked after the potato collection at Birmingham. He did a great job coaxing many different species to flower.

Having said that, one MSc student, Susan Juned, investigated morphological and enzyme diversity in the wild species Solanum chacoense. After graduating Susan joined another project on potato somaclones that was managed by myself and Brian Ford-Lloyd (see below). Another student, Ian Gubb, continued our work on the lack of enzymic blackening in Solanum hjertingii, a species from Mexico, in collaboration with the Food Research Institute in Norwich, where he grew his research materials under special quarantine licence. A couple of Peruvian students completed their degrees while working at CIP, so I had the opportunity of visiting CIP a couple of times while each was doing field work, and renew my contacts with former colleagues. In 1988, I was asked by CIP to join a panel for a three week review of a major seed production project at several locations around Peru.

With funding of the UK’s Overseas Development Administration (ODA, or whatever it was then), and now the Department for International Development (DFID), and in collaboration with the Plant Breeding Institute (PBI) in Cambridge and CIP, in 1983/84 we began an ambitious (and ultimately unsuccessful) project on true potato seed (TPS) using single seed descent (SSD) in diploid potatoes (having 24 chromosomes). Because of the potato quarantine situation at Birmingham, we established this TPS project at PBI, and over the first three years made sufficient progress for ODA to renew our grant for a second three year period.

We hit two snags, one biological, the other administrative/financial that led to us closing the project after five years. On reflection I also regret hiring the researcher we did. I’ve not had the same recruitment problem since.

Working with diploid potatoes was always going to be a challenge. They are self incompatible, meaning that the pollen from a flower ‘cannot’ fertilize the same flower. Nowadays mutant forms have been developed that overcome this incompatibility and it would be possible to undertake SSD as we envisaged. Eventually we hit a biological brick wall, and we decided the effort to pursue our goal would take more resources than we could muster. In addition, the PBI was privatized in 1987 and we had to relocate the project to Birmingham (another reason for handing over the Hawkes Collection to the CPC). We lost valuable research impetus in that move, building new facilities and the like. I think it was the right decision to pull the plug when we did, admit our lack of success, and move on.

We wrote about the philosophy and aims of this TPS project in 1984 [2], but I don’t have a copy of that publication. Later, in 1987, I wrote this review of TPS breeding [3].

Susan Juned

As I mentioned above, Brian Ford-Lloyd and I received a commercial grant to look into producing tissue-culture induced variants, or somaclones, of the crisping potato variety Record with reduced low temperature sweetening that leads to ‘blackened’ crisps (or chips in the USA) on frying. We hired Susan Juned as the researcher, and she eventually received her PhD in 1994 for this work. Since we kept the identity of each separate Record tuber from the outset of the project, over 150 tubers, and all the somaclone lines derived from each, we also showed that there were consequences for potato seed production and maintenance of healthy stocks as tissue cultures. We published that work in 1991. We also produced a few promising lines of Record for our commercial sponsor.

One funny aspect to this project is that we made it on to Page 3 of the tabloid newspaper The Sun, notorious in those days for a daily image of a well-endowed and naked young lady. Some journalist or other picked up a short research note in a university bulletin, and published an extremely short paragraph at the bottom of Page 3 (Crunch time for boffins) as if our project did not have a serious objective. In fact, I was even invited to go on the BBC breakfast show before I explained that the project had a serious objective. We weren’t just investigating ‘black bits in crisp packets’.

Brian and I (with a colleague, Martin Parry, in the Department of Geography) organized a workshop on climate change in 1989, when there was still a great deal of skepticism. We published a book in 1990 from that meeting (and followed up in 2013 with another).

Despite some successes while at Birmingham, and about to be promoted to Senior Lecturer, I had started to become disillusioned with academic life by the end of the 1980s, and began to look for new opportunities. That’s when I heard about a new position at IRRI in the Philippines: Head of the newly-established Genetic Resources Center, with responsibility for the world renowned and largest international rice genebank. I applied. The rest is history,


Klaus Lampe

I was appointed by Director General Klaus Lampe even though I’d never actually run a genebank before. Taking on a genebank as prestigious as the International Rice Genebank was rather daunting. But help was on the way.

I knew I had a good team of staff. All they needed was better direction to run a genebank efficiently, and bring the genebank’s operations up to a higher standard.

There was hardly an aspect of the operations that we didn’t overhaul. Not that I had the genebank team on my side from the outset. It took a few months for them to appreciate that my vision for the genebank was viable. Once on board, they took ownership of and responsibility for the individual operations while I kept an overview of the genebank’s operation as a whole.

I’ve written extensively in this blog about the genebank and genetic resources of rice, and in this post I gave an overview of what we achieved.

You can find more detailed stories of the issues we faced with data management and germplasm characterization, or seed conservation and regeneration (in collaboration with my good friend Professor Richard Ellis of the University of Reading). We also set about making sure that germplasm from around Asia (and Africa and the Americas) was safe in genebanks and duplicated in the International Rice Genebank. We embarked on an ambitious five year project (funded by the Swiss government) to collect rice varieties mainly (and some wild samples as well), thereby increasing the size of the genebank collection by more than 25% to around 100,000 samples or accessions. The work in Laos was particularly productive.

We did a lot of training in data management and germplasm collecting, and successfully studied how farmers manage rice varieties (for in situ or on farm conservation) in the Philippines, Vietnam, and India.

One of IRRI’s main donors is the UK government through DFID. In the early 1990s, not long after I joined IRRI, DFID launched a new initiative known as ‘Holdback’ through which some of the funding that would, under normal circumstances, have gone directly to IRRI and its sister CGIAR centers was held back to encourage collaboration between dneters and scientists in the UK.

Whenever I returned on annual home leave, I would spend some time in the lab at Birmingham. John Newbury is on the far left, Parminder Virk is third from left, and Brian Ford-Lloyd on the right (next to me). One of my GRC staff, the late Amy Juliano spent a couple of months at Birmingham learning new molecular techniques. She is on the front row, fourth from right.

With my former colleagues at the University of Birmingham (Brian Ford-Lloyd, Dr John  Newbury, and Dr Parminder Virk) and a group at the John Innes Centre in Norwich (the late Professor Mike Gale and Dr Glenn Bryan) we set about investigating how molecular markers (somewhat in their infancy back in the day) could be used describe diversity in the rice collection or identify duplicate accessions.

Not only was this successful, but we published some of the first research in plants showing the predictive value of molecular markers for quantitative traits. Dismissed at the time by some in the scientific community, the study of  associations between molecular markers and traits is now mainstream.

In January 1993, I was elected Chair while attending my first meeting of the Inter-Center Working Group on Genetic Resources (ICWG-GR) in Ethiopia (my first foray into Africa), a forum bringing expertise in genetic conservation together among the CGIAR centers.

ICWG-GR meeting held at ILCA in Addis Ababa, Ethiopia in January 1993.

Over the next three years while I was Chair, the ICWG-GR managed a review of genetic resources in the CGIAR, and a review of center genebanks. We also set up the System-Wide Genetic Resources Program, that has now become the Genebank Platform.


I never expected to remain at IRRI as long as I did, almost nineteen years. I thought maybe ten years at most, and towards the end of the 1990s I began to look around for other opportunities.

Then, in early 2001, my career took another course, and I left genetic resources behind, so to speak, and moved into senior management at IRRI as Director for Program Planning and Coordination (later Communications, DPPC). And I stayed in that role until retiring from the institute ten years ago.

Ron Cantrell

The Director General, Ron Cantrell, asked me to beef up IRRI’s resource mobilization and project management. IRRI’s reputation with its donors had slipped. It wasn’t reporting adequately, or on time, on the various projects funded at the institute. Furthermore, management was not sure just what projects were being funded, by which donor, for what period, and what commitments had been set at the beginning of each. What an indictment!

I wrote about how DPPC came into being in this blog post. One of the first tasks was to align information about projects across the institute, particularly with the Finance Office. It wasn’t rocket science. We just gave every project (from concept paper to completion) a unique ID that had to be used by everyone. We also developed a corporate brand for our project reporting so that any donor could immediately recognise a report from IRRI.

So we set about developing a comprehensive project management system, restoring IRRI’s reputation in less than a year, and helping to increase the annual budget to around US$60 million. We also took on a role in risk management, performance appraisal, and the development of IRRI’s Medium Term Plans and its Strategy.

Bob Zeigler

Then under Ron’s successor, Bob Zeigler, DPPC went from strength to strength. Looking back on it, I think those nine years in DPPC were the most productive and satisfying of my whole career. In that senior management role I’d finally found my niche. There’s no doubt that the success of DPPC was due to the great team I brought together, particularly Corinta who I plucked out of the research program where she was working as a soil chemist.

Around 2005, after Bob became the DG, I also took on line management responsibility for a number of support units: Communication and Publications Services (CPS), Library and Documentation Services (LDS), Information Technology Service (ITS), and the Development Office (DO). Corinta took over day-to-day management of IRRI’s project portfolio.

With my unit heads, L-R: Gene Hettel (CPS), Mila Ramos (LDS), Marco van den Berg (ITS), Duncan Macintosh (DO), and Corinta Guerta (DPPC).


So, ten years on, what memories I have to keep my mind ticking over during these quiet days. When I began this post (which has turned out much longer than I ever anticipated) my aim was to decide between potatoes and rice. Having worked my way through forty years of wonderful experiences, I find I cannot choose one over the other. There’s no doubt however that I made a greater contribution to research and development during my rice days.

Nevertheless, I can’t help thinking about my South American potato days with great affection, and knowing that, given the chance, I’d be back up in the Andes at a moment’s notice. Potatoes are part of me, in a way that rice never became.

Everyone needs good mentors. I hope I was a good mentor to the folks who worked with me. I was fortunate to have had great mentors. I’ve already mentioned a number of the people who had an influence on my career.

I can’t finish this overview of my forty years in international agriculture and academia without mentioning five others: Joe Smartt (University of Southampton); Trevor Williams (University of Birmingham); Roger Rowe (CIP); John Niederhauser (1990 World Food Prize Laureate); and Ken Brown (CIP)

L-R: Joe Smartt, Trevor Williams, Roger Rowe, and John Niederhauser.

  • Joe, a lecturer in genetics, encouraged me to apply for the MSc Course at Birmingham in early 1970. I guess without his encouragement (and Jack Hawkes accepting me on to the course) I never would have embarked on a career in genetic conservation and international agriculture. I kept in regular touch with Joe until he passed away in 2013.
  • At Birmingham, Trevor supervised my MSc dissertation on lentils. He was an inspirational teacher who went on to become the Director General of the International Board for Plant Genetic Resources (IBPGR) in Rome. The last time I spoke with Trevor was in 2012 when he phoned me one evening to congratulate me on being awarded an OBE. He passed away in 2015.
  • Roger joined CIP in July 1973 as Head of the Breeding and Genetics Department, from the USDA Potato Collection in Wisconsin. He was my first boss in the CGIAR, and I learnt a lot from him about research and project management. We are still in touch.
  • John was an eminent plant pathologist whose work on late blight of potatoes in Mexico led to important discoveries about the pathogen and the nature of resistance in wild potato species. John and I worked closely from 1978 to set up PRECODEPA. He had one of the sharpest (and wittiest) minds I’ve come across. John passed away in 2005.
  • Ken Brown

    Ken was a fantastic person to work with—he knew just how to manage people, was very supportive, and the last thing he ever tried to do was micromanage other people’s work. I learnt a great deal about program and people management from him.

Around the world in 40 years . . . Part 26: A sojourn in Sri Lanka

I visited Sri Lanka just the once. However, I don’t even remember which year or month. Only that it was the early 1990s, probably around 1993 or 1994. That was when I was planning a major rice conservation project at IRRI, and I wanted to determine if or how any Sri Lankan organizations would participate. As it turned out, for reasons that I’ll explain in due course, Sri Lanka did not join the project.

The Sri Lankan genebank, The Plant Genetic Resources Centre (PGRC) is based in Kandy in the island nation’s Central Province, of which it is the capital. It lies amongst the hills of the central plateau. The hills surrounding Kandy are covered in tea plantations. And, in many ways, Kandy is a magical place to visit. The scenery is outstanding.

Although I don’t remember in which hotel I stayed, I do remember it was perched on the summit of one of the hills, with views in every direction, as you can see in the gallery above. In the stillness of the dawn, I woke each morning to the sounds of birds calling to each other across the valleys. What a wonderful start to the day.

Kandy is home to a magnificent botanical garden (the Royal Botanical Gardens at Peradeniya just west of the city) and one of Buddhism’s most sacred places of worship, the Temple of the Tooth or Sri Dalada Maligawa, is located in the city center.


The Plant Genetic Resources Centre was opened in 1990. Its construction was a donation from the Government of Japan in 1989. So when I visited it had been open for just a few years—and looked like it. But, unlike one or two other genebanks whose construction Japan had supported in other Asian countries, the staff at PGRC were certainly making the most of their expanded facilities to store seeds and tissue culture or in vitro conservation.

Once again I am unable to name most of the people I met at PGRC, with one exception: Mr CN Sandanayake, who was one of my MSc students at the University of Birmingham in 1986.

CN Sandanayake talks with one of his colleagues at PGRC.

And as you can see from one of the photos in the gallery above, everything stops for tea!

When I discussed participation in the IRRI-led rice biodiversity project, it was clear that Sri Lanka had already made significant progress to collect and conserve indigenous rice varieties and wild species. My former colleague at IRRI, Dr Duncan Vaughan had visited Sri Lanka in the 1980s to help with the collection of wild rices.

Furthermore, PGRC had a cadre of excellent technical staff, and as you can see from the photos, excellent facilities for germplasm conservation. And, given the ongoing civil war there were many no-go areas in the country, especially in the north and east. However, in Kandy, there was no tangible signs of the conflict.

I made a side trip, with Sandanayake, to the Rice Research & Development Institute at Batalagoda, some 50km north of Kandy. Here are a couple of photos I took on that journey.

There I met with MS Dhanapala, a rice breeder who had also come to Birmingham in the 1980s to attend short courses on plant genetic resources, and also spend some time in the Department of Genetics.

Sitting, L-R: Dhanapala, me, Sandanayake. I don’t remember the names of those standing.

Sri Lanka has had a very successful rice breeding program, and many of its varieties have been adopted throughout Asia, after being shared and trialled through INGER, the IRRI-led International Network for the Genetic Evaluation of Rice, that I wrote about in 2015.


Now to return to Kandy tourism.

The Royal Botanic Gardens at Peradeniya cover almost 150 acres. There are wide open spaces to wander around, but also exquisite orchid houses to enjoy, with a multiplicity of species and varieties to take in.

As I mentioned, the Temple of the Tooth is a sacred shrine to Buddhists, and although not overrun with pilgrims during my visit was, nevertheless, quite busy.

One of the most impressive exhibits, in a side room, is a huge, stuffed elephant that died in 1988. This was Raja, a tusker who led ceremonial processions from the Temple for over 50 years.

All too soon my stay in Kandy was over, and I headed down to Colombo on the west coast to take my flight back to Singapore, and from there to the Philippines. It’s certainly a country I would like to return to.


 

Around the world in 40 years . . . Part 25: Walking the Great Wall of China

During the nineteen years I spent in the Far East, I visited China just twice. The first time was in March 1995, and this post is all about that visit. It must have been in 2009 that I was in China again, for the annual meeting of the CGIAR (Consultative Group on International Agricultural Research) held in Beijing, just across the street from the famous Beijing National Stadium (aka Bird’s Nest) built for the 2008 Olympic Games.

However, back to 1995.

Dr Bao-Rong Lu

A year earlier I had recruited Dr Bao-Rong Lu (a Chinese national from the southwest Sichuan Province) to work in IRRI’s Genetic Resources Center (GRC) on the diversity of wild rice species. Bao-Rong had just completed his PhD in Sweden at the Swedish University of Agriculture under the supervision Professor Roland von Bothmer, studying the cytogenetics of wheat species, if memory serves me correctly. He had also spent some months working at the Institute of Botany, The Chinese Academy of Sciences (IB-CAS), in Beijing prior to joining IRRI.

With a major rice biodiversity project getting underway at IRRI in 1995, I decided that a visit to China with Bao-Rong was the appropriate moment to initiate some further contacts and possible collaboration. Our visit took in three cities: Beijing, Hangzhou (in Zhejiang Province west of Shanghai), and Guangzhou (Canton) in the south.

First stop was the IB-CAS where I met with the Director (whose name I cannot recall, unfortunately) and many of the staff.

With the Director of the Institute of Botany and staff. Bao-Rong is standing on my left, and the Director on my right.

I was invited to present a seminar about the International Rice Genebank at IRRI and its role in the global conservation of rice genetic resources.

There was also some time for sightseeing around Beijing, and this was my opportunity to tick off another item on my bucket list: walking on the Great Wall of China (at Mutianyu, about 45 miles north of Beijing).

As you can see from these photos, there were few visitors, unlike scenes I have seen in the media in recent years.

We also took a tour of the Forbidden City in Beijing, and a walk around Tiananmen Square. Again not crowded! In one of the photos you can see the Great Hall of the People behind Bao-Rong. During the CGIAR meeting in Beijing that I mentioned earlier, the official dinner (and entertainment) was hosted by the Chinese in the Great Hall. It’s massive!

The photos appear hazy, because it was. It was quite cold in Beijing in March, with a stiff northwesterly breeze blowing over the city, laden with dust from the far west of China. It felt like being sand-blasted.

We also visited some Ming era tombs near Beijing, but I’m unable to find any photos of that particular visit.

On one night the Vice President of the Chinese Academy of Sciences hosted a small dinner in my honor. On another, Bao-Rong introduced me to the delights of spicy Sichuan cuisine. There was a Sichuan restaurant in our hotel where all the staff were from the province.

Trevor Williams

Later that same evening, as Bao-Rong and I were enjoying a beer in the bar overlooking the hotel reception, I saw someone who I recognised enter the dining room. I had to investigate. And, lo and behold, it was Trevor Williams who had supervised my MSc dissertation at the University of Birmingham in 1971. Around 1977, Trevor left Birmingham to become the first Director of the International Board for Plant Genetic Resources (IBPGR – now Bioversity International) in Rome. In 1995 I hadn’t seen Trevor for about six years, and so we spent the rest of the evening catching up over rather too many beers. Having left IBPGR by then, he was in Beijing setting up an organization that would become INBAR, the International Network for Bamboo and Rattan with its headquarters in Beijing.

After a few days in Beijing, we headed south to the city of Hangzhou (inland from Shanghai on the Qiantang River) in Zhejiang province. We were there to visit the China National Rice Research Institute (CNRRI) and meet with its director Professor Ying Cunshan. Professor Ying participated in the rice biodiversity project as a member of the project Steering Committee. CNRRI is the home of China’s largest rice genebank, which was modelled (inadvisedly in my opinion) on the genebank at IRRI.

After a couple of days in Hangzhou, we headed southwest to the city of Guangzhou (Canton) and I experienced one of the most nerve-wracking flights ever.

Much as I am fascinated by aviation in general, I’m somewhat of a nervous flyer. And in the mid-1990s Chinese airlines were only just beginning to modernise their fleets with Boeing and Airbus aircraft. Many were still flying Soviet-era Russian aircraft, like the Tupolev (probably a ‘154’) that was assigned to our flight. On that morning, flights out of Hangzhou were delayed due to fog, and at the same time Guangzhou was also fogged in. Over a period of a couple hours, other flights (of mainly new aircraft) did depart, leaving just the Tupolev on the apron for our flight. Eventually the flight was called and we made our way out to the aircraft. Looking around the cabin as I made my way to my seat, it crossed my mind that this aircraft had seen better days.

Anyway, we took off and headed for Guangzhou. Approaching that city after a flight of about 90 minutes, the captain informed us that fog was still hanging over the airport but he would continue the landing. Only to abort that just before touching down, and returning to Hangzhou! My nerves were on edge. After refuelling, and a further delay, we departed again. This time we did find a gap in the fog and landed. As we were on our final approach and seconds from touch-down, a female passenger immediately in front of me decided to get out of her seat to retrieve her hand luggage from the overhead bin. That was the final straw for me, and I shouted at her, in no uncertain terms, to sit the f*** down. Not my best moment, I admit.

In Guangzhou, our destination was the Guangzhou wild rice nursery and meet with the staff (again I don’t remember who precisely). I believe the nursery was managed through the Guangzhou Academy of Agricultural Sciences. As in Beijing, I gave another seminar here.

In a 2005 paper, Bao-Rong and others has written about wild rice conservation in China.


Completing our visit to Guangzhou, I took a flight into Hong Kong (maybe under 40 minutes) to connect with another back to Manila.

Although China did not participate directly in the rice biodiversity project since the country had already invested heavily in rice collection and conservation, Professor Ying Cunshan served on the Steering Committee for the 5-year life of the project. We felt that his experience, and recognition among other rice scientists, would be an invaluable addition to the team.

I have two particular reflections on this first trip to China. First, in crowded areas the Chinese had little ‘respect’ for personal space, and I often found myself checking my pace of walking as others crossed in front of me, seemingly oblivious of the fact that I was there. And it wasn’t just me, being a foreigner. It just seemed the normal thing to do.

Secondly, I realised that I am not a very adventurous eater. Some of the dishes I was presented with did not encourage my appetite. There was certainly a lack of synchronization between my stomach, eyes and brain. I did find Sichuanese cooking delicious, however. In Guangzhou, where many ‘exotic’ dishes were prepared, I got round any difficulties by explaining to my hosts, through Bao-Rong, that I was vegetarian. And those dishes were equally delicious.

Bao-Rong remained at IRRI for two contracts, a total of six years. After he left IRRI in 2000, he returned to China and it wasn’t long before he joined Fudan University in Shanghai. He is now Professor and Chairman of the Department of Ecology and Evolutionary Biology, and Deputy Director of the Institute of Biodiversity Science. He currently serves as a Member of the Chinese National Biosafety Committee.


 

Around the world in 40 years . . . Part 24: A Laotian experience

Laos or the Lao PDR (the Lao People’s Democratic Republic – actually a Unitary Marxist–Leninist one-party socialist republic) is one of the few landlocked countries in Asia. But it does have a connection to the sea, down the Mekong River where, through its mighty delta in Vietnam, it disgorges into the South China Sea. For a considerable length, the Mekong is the international border between Myanmar and Laos, and Thailand and Laos.

During the 19 years I spent in Asia (with the International Rice Research Institute in the Philippines) I visited Laos more than any other country, probably a couple of times a year over a five to six year period. Why? Because it was a focal country for the major rice conservation project that I managed between 1995 and 2000, funded by the Swiss government.

The Swiss, through the Swiss Agency for Development and Cooperation (SDC), also funded an in-country Lao-IRRI Program. So, as we were looking to strengthen the collection and conservation of indigenous rice varieties and wild rices in that country, it was a logical step to associate our rice biodiversity project administratively with the Lao-IRRI Project. The scientist who we hired for the Lao component of the project, Dr Seppana Appa Rao (originally from a sister center, ICRISAT, in Hyderabad, India) was based in the Lao capital Vientiane, and reported on a day-to-day basis to the leader of the Lao-IRRI Project, Australian agronomist Dr John Schiller (who passed away a couple of years ago).

Enjoying dinner with Appa Rao and John Schiller at John’s home in Vientiane.


In February 1997 I was joined on one of these visits to Laos by my wife Steph. IRRI had a generous travel policy. For every so many days a scientist was travelling outside the Philippines (but discounting the days of departure and arrival), his/her spouse or partner was entitled to one trip to a destination in Asia. So, we took advantage of that policy for a slightly extended visit to Laos (to take in some of the sights) as well as a weekend in Bangkok, through we had to transit in any case. A trip to Laos inevitably involved an overnight stop in Bangkok on both legs of the journey, taking a late flight out of Manila to Bangkok (about three hours) then the first flight on Thai Airways or Lao Aviation the next morning to Vientiane.

When I first visited Laos in 1995, the population of Vientiane was less than 400,000. It’s now reported at over 800,000. Back in the day it had the feel of a small town hugging the banks of the Mekong. But even then the traffic could become snarled at times. I wonder what it’s like nowadays? Looking at a satellite image the other day, the spread from the city center is clear. Even back in the 1990s, the city had begun to rapidly spread eastwards. The National Agricultural Research Center (NARC) of the National Agriculture and Forestry Research Institute (NAFRI) had its research station in this area, and where a rice genebank was constructed with financial support from the Swiss.


On this particular trip, Steph and I spent time with Appa and his Lao colleagues, Dr Chay Bounphanousay and Ms Kongphanh Kanyavong at the research center, looking at the genebank, field plots and various other facilities used to conserve the rice varieties collected throughout the country. This was also of interest for Steph as she originally trained in genetic resources, and has an MSc degree in genetic resources conservation  and use from the University of Birmingham (where we met in 1971/72).

L-R: Kongphanh Kanyavong, Appa Rao, and Chay Bounphanousay

We also visited a research site where wild rices were being monitored in a joint project with Japanese scientists. It was hoped that data from that project would inform the establishment of field or in situ conservation sites around the country.


Driving around Vientiane as tourists, we noted that two buildings dominate the skyline in the city center. The first, the Patuxai monument, is a huge war memorial that commemorates the struggle for independence from France. The other, a short distance away to the northeast, is Pha That Luang, a large, gold covered Buddhist stupa.

And after a hard day in the field, or touring the city and markets, what better way to end the day than a stroll along the banks of the Mekong.

That’s Thailand on the far bank.

On another day, Appa, his wife, Chay, and Kongphanh took us for a boat excursion round the Nam Ngum Reservoir, about 70 km north of Vientiane, and afterwards to the Lao Zoo nearby.


Steph and I were also invited to participate in a Baci Ceremony at John’s home, which involves the tying of white cotton strings around person’s wrists and the prayer saying or well wishing for the person that the ceremony is intended for. I had been to one of these ceremonies before, during my first visit to Laos. Another new IRRI staff member, agronomist Bruce Linquist and his family, were also welcomed to Laos at this particular ceremony.


But the tourist highlight of our visit was a weekend in Luang Prabang (a 40 min flight north of Vientiane), an ancient city standing on a peninsula at the confluence of the Mekong and the Nam Khan River.

In 1997 there were few tourists in the city besides ourselves. As we walked through the streets of the ‘old town’ the locals we passed would smile and say hello, and go on about their business. They paid no attention to us whatsoever. Luang Prabang has become a mecca for tourists from afar, and must be a very different place nowadays.

After checking into our hotel (I don’t remember which one—it was new and on the southwest of the city center), we set out to explore the sights.

First on our list was the sixteenth century Buddhist temple Wat Xieng Thong, or Temple of the Golden City, at the northern end of the peninsula. It is one of the most important shrines in the country.

The architecture is breathtaking, and as we wandered around the temple, there was a just a feeling of serenity.

Later in the day before sunset, we climbed 100m high Phousi Hill to enjoy the 360° panorama from the summit, looking north over the old town and the Nam Khan River.


I guess the highlight of our trip to Luang Prabang was the 25 km or so boat trip we took upstream along the Mekong to visit the shrines at the Pak Ou Caves, which are opposite the mouth of the Ou River as it flows into the Mekong.

As I already mentioned, Luang Prabang was very quiet, and we hired a river boat to ourselves. The journey took about two hours, during which we had the chance to take in, close-up, the majesty of the Mekong.

At the landing stage where we took our boat. You can see several of these boats behind Steph, looking north along the Mekong.

Approaching the landing stage at Pak-Ou, our boatman carefully positioned his boat so that we could disembark safely. While we were ashore, he turned the boat around ready for the return, but also a short diversion into the mouth of the Ou River.

There are two caves: Tham Ting is the lower; Tham Phum is the upper. Both are filled with hundreds if not thousands of Buddha sculptures.

We were the only visitors on this day, and had the site to ourselves. Nowadays, it’s rather different as this photo (copied from the website http://www.viajeasean.com) clearly shows.

After a late afternoon meal overlooking the Mekong back in Luang Prabang, our visit to this ancient city came to an end, and we flew back to Vientiane the following morning, and on to Bangkok.


 

Genebanks are the future . . . but there is a big challenge ahead

Our ability to adapt to changing climates will be determined, to a considerable extent, upon our ability to feed ourselves, to provide shelter and clothing, and for many peoples in many developing countries there will be problems in obtaining fuelwood for cooking or heating.

My close friend and former colleague Professor Brian Ford-Lloyd and I wrote that 30 years ago in the first chapter [1] of the book on climate change and genetic resources that we edited with Martin Parry.

We also wrote that to avert famine it would be necessary to raise crop yields and identify and use the sorts of genetic resources to contribute to this effort. Fortunately, these genetic resources are, to a large extent, already conserved in genebanks around the world.

In a recent post, I argued that, in the face of climate change, genebanks are the future. And while I hold to that assertion, I must also highlight a challenge that must be addressed—with greater urgency—and one that I already raised 30 years ago!

And that challenge is all about the potential impacts of climate change on genebank operations. I’m concerned about how rising temperatures and changing seasons might affect the ability of a genebank to produce good quality seeds during initial multiplication or thereafter to regenerate seed stocks.

We also have limited information how the environmental pest and plant pathogen load will change under a changing climate. That’s a particular concern for plant species that cannot be stored as seeds but are conserved in field genebanks. In this, the International Year of Plant Health, it is a particular genebank issue worthy of more attention.

Furthermore, we shouldn’t discount possible increases in genebank costs as cooling equipment works harder to maintain cold rooms at the desired temperatures of -18°C for long-term conservation (in so-called Base Collections), or just above 0°C for germplasm that is available for distribution and exchange (in Active Collections), the situation found in many genebanks.


Many (but not all) genebanks were set up in parts of the world where the crops they conserve are important, and where many originated, in so-called ‘centers of diversity’. That holds particularly for the international genebanks managed in eleven of the CGIAR centers, such as for potatoes at the International Potato Center (CIP) in Peru, beans and cassava at the International Center for Tropical Agriculture (CIAT) in Colombia, or rice at the International Rice Research Institute (IRRI) in the Philippines, to give just three examples.

But there are exceptions. CIMMYT, the International Maize and Wheat Improvement Center (located just outside Mexico City) certainly lies in the center of diversity for maize, but not wheat, which is a crop that was domesticated and evolved under domestication in the Near East and fringes of the Mediterranean. Another exception is Bioversity International, based in Rome that maintains an important collection of bananas (Musa spp.) as tissue culture samples (known as in vitro conservation) as well as samples stored frozen (or cryopreserved) at the temperature of liquid nitrogen (-196°C) in Belgium at the Katholieke Universiteit Leuven (KU Leuven).

You can find out more about the CGIAR genebanks on the Genebank Platform website.

As the network of genebanks expanded worldwide, with almost every country setting up at least one national genebank, many genebanks now hold samples of varieties and wild species from distance regions. And it does have some important implications for long-term conservation and regeneration, and exchange of germplasm.


Long-term conservation of many plant species in genebanks is possible because their seeds can be dried to a low moisture content and stored at low temperature. We refer to these seeds as orthodox, and we have a pretty good idea of how to dry them to an optimum moisture content (although research at IRRI has thrown new light on some of the critical drying processes). Provided they can be kept dry and cool, we can predict—with some confidence—how long they will survive in storage before they need to be grown again, or ‘regenerated’, to produce healthy seeds stocks.

On the other hand, the seeds of some species, many from the tropics, do not tolerate desiccation or low temperature storage. We refer to the seeds of these species as recalcitrant. There again, there is also a group of crops that cannot be stored as seeds but must be maintained, like the banana example referred to above, as tissue cultures or cryopreserved, if technically feasible; or in field genebanks because they reproduce vegetatively. The potato for example is grown from tubers, and for any variety, each tuber is genetically identical (a clone) to all the others of that variety. Although potatoes do produce seeds (often in abundance), they do not breed true. That’s why conservation of the original varieties is so important.

However, seeds do not live forever, and periodically regenerated if there are signs of declining viability. Or when seed stocks have become depleted because they have been sent to breeders and researchers around the world.


Climate change is already affecting crop productivity in some parts of the world. Increases in temperature (notably higher nighttime temperatures) are linked with a reduction of fertility in rice [2] for example. Stressed plants produce seeds of lower quality and, in wheat, have an effect on seedling vigour and potentially on yield [3].

Many (perhaps most) genebanks aim to grow their germplasm close to the genebank location, although this may not always be possible. Will the environments of genebank locations remain constant under climate change? Most certainly not. Temperatures have already risen, and are predicted to increase even further unless governments really do take concerted action to reduce our carbon footprint. While temperatures will increase, daylength will remain constant. Under climate change we will see new combinations of temperature and daylength. Response to daylength (or photoperiodism) is a key adaptive trait in many plant species. It is already a challenge to grow some genebank samples at a single location because of their wide latitudinal provenance.

Richard Ellis

Incidentally, 30 years on, it’s worthwhile to take a second look at Chapter 6 in our genetic resources and climate change book [4] by Professor Richard Ellis and colleagues at the University of Reading on the relationship between temperature and crop development and growth.

Seed quality is all important for genebank managers. Unlike farmers, however, they are less concerned about yield per se. They do need to understand the impacts of higher temperatures, drought, or submergence—and when they occur in a plant’s life cycle—on seed quality, because seed quality is a key determinant of long-term survival of seeds.

In a recent article, Richard wrote this: . . . when scientists breed new crop varieties using genebank samples as “parents”, they should include the ability to produce high-quality seed in stressful environments in the variety’s selected traits. In this way, we should be able to produce new varieties of seeds that can withstand the increasingly extreme pressures of climate change.

While a genebank might be able to regenerate its conserved germplasm closeby today, to what extent will these ‘regeneration environments’ become ‘stressful environments’ under a changing climate? What measures must a genebank take to ensure the production of the highest quality seeds? Furthermore, how will the pest and disease load change, and what impact will that have during regeneration and, perhaps more importantly, on germplasm conserved in field genebanks?

We were faced by a similar situation almost 30 years ago after I had joined IRRI. There’s no question that IRRI conserves, in its International Rice Genebank, the world’s largest and genetically most diverse collection of rice varieties and wild species.

Kameswara Rao

One important group of rice varieties, the so-called japonica rices originated in temperate zones, and it was tricky to produce high quality seeds in Los Baños (14°N). With my colleague Kameswara Rao (who received his PhD in Richard’s lab at Reading), we carefully analysed the factors affecting seed quality in the japonica varieties grown in Los Baños [5], and adapted the regeneration cycle to the most appropriate time of year. Given that water was not a limiting factor (there were irrigation ponds on the IRRI Experiment Station) we were not constrained by the changing seasons as such. This would not be possible for all genebanks where growing seasons are more differentiated, in terms of temperature and water availability.


I did look into the possibility of growing the japonica (and other ‘difficult’ varieties) at other sites, even outside the Philippines. What seemed, at the outset, as a logical solution to a challenging problem, became a logistical nightmare.

I was concerned that the International Rice Genebank could ‘lose’ control of the management of germplasm samples in the field unless genebank staff were assigned to oversee that work, even in another country. Afterall, the reputation of the genebank lies in its ability to safely conserve germplasm over the long-term and safely distribute seeds, conditions I was not prepared to compromise.

There were also various plant quarantine issues, seemingly insurmountable. Plant quarantine personnel are, by outlook, a conservative bunch of people. And with good reason. IRRI successfully operates its germplasm exchange (both receipt and distribution) under the auspices of the Philippines Department of Agriculture’s National Plant Quarantine Services Division (of the Bureau of Plant Industry). The institute’s Seed Health Unit carries out all the tests necessary to certify all imports and exports of rice seeds meet exacting quarantine standards. All samples received by IRRI must be tested and, if they are destined for future distribution, must be grown in the field at IRRI for further observation and certification. That would negate the advantages of producing seeds in a ‘better’ environment. Countries like the USA or Russia that cover a huge range of latitude and longitude have a network of experiment stations where germplasm could be grown, and under the same plant quarantine jurisdiction. For many countries and their genebanks, that will just not be an option.

So the challenge for genebank managers is to make sure the impact of climate change on germplasm management and exchange is part of risk management. And begin discussions (if they have not already started) to determine how inter-genebank collaboration could overcome some of the potential constraints I have raised.

Never have genebanks been so relevant . . . or needed

There has perhaps never been a better justification for conservation of seeds in genebanks, or ex situ conservation as it’s commonly known.

The devastating bush fires that have ravaged huge swathes of eastern Australia have highlighted the fragility of environments that are being affected adversely by the consequences of climate change. It’s a wake-up call, even though some of us were commenting on this a generation ago (and more recently in 2014).

While many news stories have emotionally focused on the impact of the fires on wildlife—the injury to and death of millions of animals—very little has appeared in the media about the impacts on plant species. One story stood out, however: the extraordinary measures that firefighters took to protect the only natural stand of ancient Wollemi pines at a secret location in the Blue Mountains west of Sydney.

In another story I came across, there are concerns that a wild species of sorghum native to East Gippsland in southeast Australia may now be headed towards extinction as fires swept across its habitats. Only time will tell whether this particular species has survived.

Bush fires are not uncommon in Australia and many other parts of the world. Vegetation is, however, quite resilient and, given time, often recovers to a semblance of what was there before fires ravaged the landscape, although the balance of species may be disrupted for a few years.

Clearly nature is under threat. Indeed, in an article in The Guardian on 20 January 2020 the acting executive secretary of the UN Convention on Biological Diversity, Elizabeth Maruma Mrema, is quoted as imploring ‘governments to ensure 2020 is not just another “year of conferences” on the ongoing ecological destruction of the planet, urging countries to take definitive action on deforestation, pollution and the climate crisis.’

Catastrophic fires, and other effects of environmental degradation and climate change, vividly illustrate the necessity of having a dual conservation strategy, backing up conservation in nature, or in situ conservation, with conservation of seeds in genebanks, where appropriate. It’s clear that relying in situ conservation alone is too high a risk to take.

About 25 years ago, while I was leading the genetic conservation program at the International Rice Research Institute (IRRI) in the Philippines, and conserving the world’s largest and most diverse collection of rice varieties and wild species in the International Rice Genebank, vocal lobby groups were pressing hard in several international forums and the media to redirect conservation away from genebanks (they were often referred to as ‘gene morgues’) towards in situ conservation, in nature for wild species or on-farm for cultivated varieties.

The criticism of many genebanks, including some of those managed at centers of the Consultative Group for International Agricultural Research or CGIAR, was not unwarranted. Insufficient attention was given to applying internationally-agreed genebank standards. This was not entirely the fault of genebank managers, both inside and outside the CGIAR. They were often starved of funds, living hand to mouth, year to year as it were, and expected to manage a long-term conservation commitment on inadequate annual budgets.

Standards in the eleven CGIAR genebanks have been raised through the Genebank Platform, supported by the Crop Trust. Between them, not only do the CGIAR genebanks conserve some of the most world’s important collections of genetic resources of cereals, legumes, and roots and tubers, but these collections have been studied in depth to find useful traits, and the volume of germplasm shared annually for research and production is impressive. Just take a look at the data for the years 2012-2018.

Other international efforts like the Crop Wild Relatives Project (supported by the Government of Norway), and managed by the Crop Trust with the Royal Botanic Gardens, Kew have focused attention on the importance of conserving the wild relatives of crop plants as they are often genetically endowed with traits not found in their domesticated derivatives. My own experience studying nematode resistance in wild potatoes from Bolivia for example illustrated the importance of wild species for crop improvement.

Today, we have a whole new suite of tools to study the crop varieties and wild species conserved in genebanks around the world. As the genome of each new species is sequenced, another door is opened on the genetic diversity of nature, how it’s organized, and how genes control different traits. Indeed an argument has recently been made to genotype all samples (or accessions in the ‘official’ parlance) in a genebank. Certainly this is an approach that was merely a dream only two decades ago.

I still argue, however, that in tandem with the molecular analysis of crop diversity, there must be an in-depth evaluation of how different varieties behave in real environments. In joint research between former colleagues of mine at The University of Birmingham (Professors Brian Ford-Lloyd and John Newbury and Dr Parminder Virk) and myself at IRRI in the 1990s, we demonstrated the predictive value of molecular markers for several quantitative characters associated with crop productivity. Somewhat derided at the time, association genetics has become an important approach to study crop diversity.

I’ve been publishing about climate change and the value of plant genetic resources for over 30 years, beginning when there was far more skepticism about this phenomenon than today. At a conference on Crop Networks, held in Wageningen in the Netherlands in December 1990, I presented a paper outlining the need for collaborative research to study germplasm collections in the face of climate change.

And in that paper I argued that widespread testing in replicated field trials would be necessary to identify useful germplasm. With the addition nowadays of molecular markers and genome-wide detailed information for many species, there is now a much better opportunity to evaluate germplasm to identify gene sources that can help protect crops against the worst ravages of climate change and maintain agricultural productivity. Even though political leaders like Donald Trump and Scott Morrison continue to deny climate change (or merely pay lip service), society as a whole cannot ignore the issue. Afterall, for a predicted global population of 9.8 billion by 2050, most of whom will not produce their own food, continued agricultural productivity is an absolute necessity. The conservation, evaluation, and use of plant genetic resources stored in the world’s genebanks is a key component of achieving that goal.

Genebanks are the future! However, in a follow-up story, I write that genebanks still face a major challenge under a changing climate. Read more here.

Have [botany] degree . . . will travel (#iamabotanist)

One thing I had known from a young boy was that I wanted to see the world; and work overseas if possible. Following somewhat in the footsteps of my parents, Fred and Lilian Jackson.

Who would have thought that a degree in botany would open up so many opportunities?

Come 1 January, it will be 47 years since I joined the staff of the International Potato Center (CIP) in Lima, Peru, and the start of a 37 year career in the plant sciences: as a researcher, teacher, and manager. Where has the time flown?

After eight years in South and Central America, I spent a decade on the faculty of the School of Biological Sciences at the University of Birmingham. Then, in 1991, I headed to Southeast Asia, spending almost 19 years at the International Rice Research Institute (IRRI) in the Philippines, before retiring in 2010.

However, I have to admit that Lady Luck has often been on my side, because my academic career didn’t get off to an auspicious start and almost thwarted my ambitions.

While I enjoyed my BSc degree course at the University of Southampton (in environmental botany and geography) I was frankly not a very talented nor particularly industrious student. I just didn’t know how to study, and always came up short in exams. And, on reflection, I guess I burnt the candle more at one end than the other.

It would hard to underestimate just how disappointed I was, in June 1970, to learn I’d been awarded a Lower Second Class (2ii) degree, not the Upper Second (2i) that I aspired to. I could have kicked myself. Why had I not applied myself better?

But redemption was on the horizon.

Prof. Jack Hawkes

In February 1970, Professor Jack Hawkes (head of the Department of Botany at the University of Birmingham) interviewed me for a place on the MSc Course Conservation and Utilization of Plant Genetic Resources, that had opened its doors to the first cohort some months earlier. I must have made a favorable impression, because he offered me a place for September.

But how was I to support myself for the one year course, and pay the tuition  fees? I didn’t have any private means and, in 1970, the Course had not yet been recognized for designated studentships by any of the UK’s research councils.

Through the summer months I was on tenterhooks, and with the end of August approaching, started seriously to think about finding a job instead.

Then salvation arrived in the form of a phone call from Professor Hawkes, that the university had awarded me a modest studentship to cover living expenses and accommodation (about £5 a week, or equivalent to about £66 in today’s money) as well as paying the tuition fees. I could hardly believe the good news.

Prof. Trevor Williams

By the middle of September I joined four other students (from Venezuela, Pakistan, Turkey, and Nigeria) to learn all about the importance of crop plant diversity. Over the next year, discovered my academic mojo. I completed my MSc dissertation on lentils under Course Tutor (and future Director General of the International Board for Plant Genetic Resources, now Bioversity International), Professor Trevor Williams.

Starting a career in international agricultural research
Just before Christmas 1970, Hawkes traveled to Peru and Bolivia to collect wild potatoes. On his return in February 1971, he dangled the possibility of a one year position in Peru (somewhere I had always wanted to visit) to manage the potato germplasm collection at CIP while a Peruvian researcher came to Birmingham for training on the MSc Course. Then, in mid-summer, CIP’s Director General, Dr. Richard Sawyer, visited Birmingham and confirmed the position at CIP beginning in September 1971.

But things didn’t exactly go to plan. Funding from the British government’s overseas development aid budget to support my position at CIP didn’t materialise until January 1973. So, during the intervening 15 months, I began a PhD research project on potatoes (under the supervision of Professor Hawkes), continuing with that particular project as part of my overall duties once I’d joined CIP in Lima, under the co-supervision of Dr. Roger Rowe. That work took me all over the Andes—by road, on horseback, and on foot—collecting native varieties of potatoes for the CIP genebank.

Screening potatoes in Turrialba, Costa Rica for resistance to bacterial wilt.

After successfully completing my PhD in December 1975, I transferred to CIP’s Outreach Program in Central America, moved to Costa Rica for the next 4½ years, and began research on potato diseases, adaptation of potatoes to warm climates, and seed production. This was quite a change from my thesis research, but I acquired valuable experience about many different aspects of potato production. I learnt to grow a crop of potatoes!

But this posting was not just about research. After a year, my regional leader (based in Mexico) moved to the USA to pursue his PhD, and CIP asked me to take over as regional research leader. Thus I began to develop an interest in and (if I might be permitted to say) a flair for research management. In this role I traveled extensively throughout Central America and Mexico, and the Caribbean Islands, and helped to found and establish one of the most enduring and successful research partnerships between national research programs and any international agricultural research institute: PRECODEPA.

Then, just as I was thinking about a move to CIP’s regional office in the Philippines (for Southeast Asia), an entirely different opportunity opened up, and we moved back to the UK.

Back to Birmingham
In January 1981 I successfully applied for a Lectureship in my old department (now named the Department of Plant Biology) at Birmingham. I said goodbye to CIP in March 1981, and embarked on the next stage of my career: teaching botany.

The lectureship had been created to ensure continuity of teaching in various aspects of the conservation and use of plant genetic resources (and other topics) after Professor Hawkes’ retirement in September 1982. I assumed his particular teaching load, in crop plant evolution and germplasm collecting on the MSc Course, and flowering plant taxonomy to second year undergraduates, as well as developing other courses at both undergraduate and graduate level.

In addition to my continuing research interest on potatoes I assembled a large collection of Lathyrus species and one PhD student from Malaysia made an excellent study of species relationships of the one cultivated species, the grasspea, L. sativus. I successfully supervised (or co-supervised) the theses of nine other PhD students (and at least a couple of dozen MSc students) during the decade I spent at Birmingham.

I generally enjoyed the teaching and interaction with students more than research. Having struggled as an undergraduate myself, I think I could empathise with students who found themselves in the same boat, so-to-speak. I took my tutor/tutee responsibilities very seriously. In fact, I did and still believe that providing appropriate and timely tutorial advice to undergraduates was one of the more important roles I had. My door was always open for tutees to drop by, to discuss any issues in addition to the more formal meetings we had on a fortnightly basis when we’d discuss some work they had prepared for me, and I gave feedback.

While I appreciate that university staff are under increasing pressures to perform nowadays (more research, more grants, more papers) I just cannot accept that many consider their tutor responsibilities so relatively unimportant, assigning just an hour or so a week (or less) when they make themselves accessible by their tutees.

The 1980s were a turbulent time in the UK. Politics were dominated by the Tories under Margaret Thatcher. And government policies came to significantly affect the higher education sector. By the end of the decade I was feeling rather disillusioned by university life, and although I was pretty confident of promotion to Senior Lecturer, I also knew that if any other opportunity came along, I would look at it seriously.

And in September 1990 just such an opportunity did come along, in the form of an announcement that IRRI was recruiting a head for the newly-created Genetic Resources Center.

Dr. Klaus Lampe

A return to international agriculture
It was early January 1991, and I was on a delayed flight to Hong Kong on my way to the Philippines for an interview. Arriving in Los Baños around 1 am (rather than 3 pm the previous afternoon), I had just a few hours sleep before a breakfast meeting with the Director General, Dr. Klaus Lampe and his two deputies. Severely jet-lagged, I guess I more or less sleep-walked through the next three days of interviews, as well as delivering a seminar. And the outcome? IRRI offered me the position at the end of January, and I moved to the Philippines on 1 July remaining there for almost 19 years.

For the first ten years, management of the International Rice Genebank (the world’s largest collection of rice varieties and wild species) was my main priority. I have written about many aspects of running a genebank in this blog, as well as discussing the dual roles of genebank management and scientific research. So I won’t repeat that here. Making sure the rice germplasm was safe and conserved in the genebank to the highest standards were the focus of my early efforts. We looked at better ways of growing diverse varieties in the single environment of IRRI’s Experiment Station, and overhauled the genebank data management system. We also spent time studying the diversity of rice varieties and wild species, eventually using a whole array of molecular markers and, in the process, establishing excellent collaboration with former colleagues at the University of Birmingham and the John Innes Centre in Norwich, UK.

Dr. Ron Cantrell

Then, one day in early 2001, IRRI’s Director General, Dr. Ron Cantrell, called me to his office, asking me to give up genebanking and join the institute’s senior management team as Director for Program Planning and Communications. As I said earlier, I really enjoyed management, but wasn’t sure I wanted to leave research (and genetic resources) behind altogether. But after some serious soul-searching, I did move across in May 2001 and remained in that position until my retirement in April 2010.

Even in that position, my background and experience in the plant sciences was invaluable. All research project proposals for example passed through my office for review and submission to various donors for funding. I was able not only look at the feasibility of any given project in terms of its objectives and proposed outcomes within the project timeframe, I could comment on many of the specific scientific aspects and highlight any inconsistencies. Because we had a well-structured project proposal development and submission process, the quality of IRRI projects increased, as well as the number that were successfully supported. IRRI’s budget increased to new levels, and confidence in the institute’s research strategy and agenda gained increased confidence among its donors.

What a good decision I made all those years ago to study botany. I achieved that early ambition to travel all over the world (>60 countries in connection with my work) in North and South America, Europe, Africa, Asia, and Australia. But the study (and use) of plants gave me so much more. I used the knowledge and experience gained to help transform lives of some of the poorest farmers and their families, by contributing to efforts to grow better yielding crops, more resilient to climate change, and resistant to diseases.

I’m sure that a degree in botany would be the last in many people’s minds as leading to so many opportunities such as I enjoyed. Knowing that opportunities are out there is one thing. Seizing those opportunities is quite another. And I seized them with both hands. I never looked back.

I should also mention that I also ascribe some of my success to having had excellent mentors—many mentioned in this piece—throughout my career to whom I could turn for advice. Thank you!

Management and science – are they equally important roles for a genebank manager?

There’s an interesting article by Nicola Temple and Michael Major (science communications specialists for Scriptoria and the Crop Trust, respectively), on the Genebank Platform website, about Dr David Ellis who retired at the end of 2018 as head of the genebank at the International Potato Center (CIP) in Lima, Peru (where I began my career in international agricultural research in January 1973).

Titled David Ellis: Finding the balance between manager and scientist, the article describes David’s illustrious career, and highlights an important issue that many genebank managers face. Let me quote directly what they wrote:

David argues that genebank managers need to balance science with the management of their collections. “If you focus purely on the science, then management of the genebank suffers,” he says. “If you focus solely on being a genebank manager, then you are never viewed by your scientific peers as a research scientist and that can mean fewer opportunities for collaboration.”

His perspectives—which I fully endorse—resonated with me, and got me thinking about the time, almost 30 years ago, when I joined the International Rice Research Institute (IRRI) in the Philippines as Head of the newly-created Genetic Resources Center (GRC) with responsibility for (among other things) the internationally-important rice genebank, the International Rice Germplasm Center that, in the fullness of time, we renamed the International Rice Genebank. I was head of GRC for a decade, after which I changed roles at IRRI, and relinquishing all my genetic resources responsibilities.

A career in genetic resources
By July 1991, I’d already been working on the conservation and use of plant genetic resources for twenty years. I’d studied at the University of Birmingham under Professor Jack Hawkes and Professor Trevor Williams, and had forged a career at CIP (in Peru and Central America) for over eight years, before returning to Birmingham to join the faculty of the School of Biological Sciences (helping to train the next generation of germplasm scientists).

However, until joining IRRI, I’d never managed a genebank.

I first heard about the job at IRRI in September 1990, when a position announcement landed on my desk in the morning post. I was intrigued. Who had sent this to me? At the same time, the thought of running a genebank was rather attractive, because by 1990 I had become somewhat disillusioned with academic life.

The IRRI position represented an opportunity to return to international agricultural research that I had enjoyed during my years with CIP from 1973-1981.

As initially advertised, the Head of the Genetic Resources Center position was described merely as a service role with no assigned research responsibilities whatsoever. The Head would report directly to the Deputy Director General (International Programs)—not the DDG (Research).

On the positive side, however, the position would be equivalent to other Division Heads and Program Leaders giving the incumbent an opportunity to represent the genebank directly in institute management discussions.

Having sent in my application, I traveled to the Philippines in early January 1991 for an interview, and was offered the position three weeks later. During the interview(s), and in the subsequent negotiations to iron out the terms and conditions of my appointment, I made it a condition of accepting that I (and my future GRC staff) would have a research role. Indeed, without that commitment and support from senior management, I was not interested in the position. I can be persuasive. My viewpoint prevailed!

Learning about genebanking – on the job
Management and science are almost equally important roles. But not quite. Management and safety of any genebank collection (including making it available to users worldwide) must always be the top priority.

Dr TT Chang

Before 1991 there had been just one person—eminent rice geneticist and upland rice breeder, Dr TT Chang—as head of the genebank for about thirty years. Very quickly I realised that some important changes must be made, and the best known genebank practices and standards adopted. And that’s where I focused my efforts for the first three years of my tenure in GRC.

Initially I had to immerse myself in how the genebank was being managed, especially in terms of staffing needs and people management, and to develop a plan to make it run much more efficiently. That meant identifying and appointing staff to lead critical functions in the genebank like seed conservation, field operations (multiplication of genebank accessions and rejuvenation), characterization, or data management. Finding or assigning existing staff for the right roles.

What I did find was a highly motivated and professional staff who had never received any real guidance as to their roles, nor had they been given any specific responsibilities. As a consequence, productivity was rather low, as different members of staff overlapped in their day-to-day activities, sometimes at cross purposes.

It took me about six months to understand just how the genebank functioned, and how many operations needed to be updated. But I also had the tricky task of ‘side-lining’ the most senior of the national staff, Eves Loresto, from the line of communication to me from other staff members. She had been Dr Chang’s assistant, and nothing reached him from the staff unless it passed through her first. This was, I felt, an obvious obstacle to accomplishing the necessary changes to staff roles and productivity. Ultimately I found her an important role in leading various components of an externally-funded biodiversity project (by the Swiss government) that I couldn’t have managed on my own.

It took about three years, but we overhauled almost everything that the genebank did (and producing an important manual of genebank operations, something that all CGIAR genebanks are now expected to have). One of the key problem areas was data management, a complete nightmare, as I have described elsewhere on my blog.

We brought all field operations back on to the IRRI Experiment Station, and through investment in facilities, we were able to remodel and upgrade the genebank cold stores, the seed testing laboratory, and germplasm handling protocols for responding efficiently to requests for rice germplasm, in conjunction with the Seed Health Unit which handled all aspects of quarantine and phytosanitary certification for import and export of rice seeds.

We also made sure that the collection was fully duplicated at the USDA National Laboratory for Genetic Resources Preservation in Fort Collins, CO, an initiative that had begun under my predecessor, but needed acceleration.

By the time of the first CGIAR system-wide review of genebanks that was completed in 1994-95, IRRI’s genebank was rated as ‘a model for others to emulate‘. While IRRI did invest in the genebank (improved configuration of storage rooms, laboratories, seed drying, etc.), much of what we achieved in the genebank did not actually require much additional or even special funding. Just a realignment of the way the genebank operated. And a lot of hard work by great staff to make the necessary improvements. I can’t stress too much how important it was to have the staff onside, and spending much effort in people management, including having more than 70% of all positions in GRC upgraded and staff promoted.

You can see much of how the genebank operates in this video below. And while it’s true that my successor, Dr Ruaraidh Sackville Hamilton built on the improvements made during the 1990s, we achieved the current genebank standards, and this permitted IRRI to move to the next level and meet its obligations and performance targets under the current funding structure of the Genebank Platform.

As the staff grew into their roles in the genebank, there was more opportunity to reach out to national rice programs around Asia, as well in Africa and Latin America. We helped train a large cadre of national scientists in genebank data management and, to accompany germplasm collecting, we offered practical workshops. National programs then shared collected germplasm with IRRI, and the size of the International Rice Genebank Collection grew by about 25% between 1995 and 2000. Overall, there were 48 courses in 14 countries. For details, see the project final report.

Turning to research
In July 1991, GRC had essentially no research profile whatsoever. Just a few minor studies, tinkering around the edges of research. From 1994 or thereabouts, that all changed. We invested time, people, and funds to:

  • Study the effects of seed production environment and seed quality and survival in storage;
  • Understand the diversity of rice using molecular markers;
  • Clarify the taxonomy of rice species, primarily those most closely related to Oryza sativa, the rice grown widely around the world; and
  • Understand the dynamics of rice conservation by farmers from the joint perspectives of population genetics and social anthropology.

Because we started from such a low base, I decided to forge important collaborations with several research groups to kick-start our research efforts.

Dr Kameswara Rao

In terms of seed production (and seed conservation), we had an excellent collaboration with Professor Richard Ellis at the University of Reading in the UK. We also hired a postdoc, Dr Kameswara Rao (from ICRISAT in Hyderabad, India) to work at IRRI on these joint projects. Kameswara had completed his PhD at Reading under the supervision of Professor Eric Roberts. After leaving IRRI, Kameswara joined the genebank program at the International Center for Biosaline Agriculture in Dubai, UAE; he has since retired.

Dr Parminder Virk

The use of molecular markers to study crop diversity was in its infancy in the early 1990s, although as I pointed out in a recent blog post, a number of molecular approaches had been used during the 1980s and earlier in different labs. We partnered with my former colleagues at the University of Birmingham, Professors Brian Ford-Lloyd and John Newbury (now retired) and Dr Parminder Virk (who eventually joined IRRI as a rice breeder and is now with the HarvestPlus program in India), in collaboration with the late Professor Mike Gale’s group at the John Innes Centre in Norwich.

These were highly effective collaborations, and we also built up our in-house capacity by sending one of the GRC staff for short-term training at Birmingham (sponsored by the British Council) while developing a molecular marker laboratory in GRC.

We undertook all taxonomy research in-house, and hired Dr Lu Bao-Rong from China to lead this effort. We also assigned two staff full-time to the molecular and taxonomy research, and support staff as well.

The on-farm conservation research was one component of the Swiss-funded biodiversity project I referred to earlier. One scientist, Dr Jean-Louis Pham came to IRRI from the French public research institution IRD in Montpellier to head the on-farm group.

I think we accomplished a great deal in the decade I was in charge of the International Rice Genebank. We established a solid foundation to take the genebank forward over the next two decades. I have listed below most of the GRC publications that appeared during this period. Links to PDF files of many of the papers can be found here.

The molecular marker and genomics research was strengthened in 2001 (as I was coming to the end of my tenure in GRC) with the appointment of Dr Ken McNally.

Dr Ken McNally and Dr Fiona Hay

Around 2002 a seed physiologist, Dr Fiona Hay, joined GRC and although she has now moved to Aarhus University in Denmark, her research on seed drying and storage contributed significantly towards safeguarding this valuable germplasm collection.

Looking back on the 1990s, I think GRC can be proud of its research output. We did, as David Ellis proposed, establish our scientific credibility and, in a number of forums, took that message out to the wider scientific community and the public at large. Always, however, knowing that the genebank collection was safe for the long term, and available and accessible to everyone around the world who had need of germplasm to improve rice—which is, after all, the world’s most important staple crop.

Are you plant blind?

In our 1986 book Plant Genetic Resources: An Introduction to their Conservation and Use, my former colleague and friend of almost 50 years, Professor Brian Ford-Lloyd and I wrote (on page 1):

To most people the word ‘conservation’ conjures up visions of lovable cuddly animals like giant pandas on the verge of extinction. Or it refers to the prevention of the mass slaughter of endangered whale species, under threat because of human’s greed and short-sightedness. Comparatively few  however, are moved to action or financial contribution by the idea of economically important plant genes disappearing from the face of the earth. . . . But plant genetic resources make little impression on the heart even though their disappearance could herald famine on a greater scale than ever seen before, leading to ultimate world-wide disaster.

Hyperbole? Perhaps. Through our 1986 lens that did not seem far-fetched. And while it’s fair to say that the situation today is better in some respects than Brian and I predicted, there are new threats and challenges, such as global warming.

The world needs genetic diversity to breed varieties of crops that will keep agricultural systems sustainable, allow production of crops in drought-prone regions, where temperatures are increasing, and where new races of diseases threaten even the very existence of agriculture for some crops.

That genetic diversity comes from the hundreds of thousands of crop varieties that farmers have nurtured for generations since the birth of agriculture millennia ago, or in closely related wild species. After all, all crops were once wild species before domestication.

These are the genetic resources that must be safely guarded for future generations.

The work of the International Board for Plant Genetic Resources (IBPGR), then the International Plant Genetic Resources Institute (IPGRI), was pivotal in coordinating and supporting genetic resources programs worldwide, in the 1970s, 80s and 90s.

Then a new and very important player came along. Over the past decade and half the Crop Trust, has provided long-term support to some of the world’s most important genebanks.

International mechanisms have been put in place to support collection, conservation, study, and use of plant genetic resources. Yet, much remains to be done. And ‘Joe Public’ is probably still as unaware of the importance of the crop varieties and their wild relatives (and perhaps plants in general) as we feared more than three decades ago.


Wildlife programs on TV are mostly about animals, apart from the weekly gardening programs, and some such as David Attenborough’s The Private Life of Plants (broadcast in 1995). Animal programs attract attention for precisely the reasons that Brian and I highlighted in 1986. A couple of nights ago for instance I watched a fascinating, hour-long program on the BBC about hippos in the Okavango Delta of Botswana. Wonderful footage revealing never-before-seen hippo behaviour and ecology.

When it comes to genetic resources, animals don’t do so badly either, at least here in the UK. We get an almost weekly item about the importance of rare breeds of livestock and their imperiled status during the BBC’s flagship Countryfile program on Sunday evenings presented by farmer Adam Henson, whose father Joe helped set up the Rare Breeds Survival Trust (RBST) in 1973. The RBST has been pivotal in rescuing many breeds from the brink of extinction. Just last night (28 July) Adam proudly showed an Albion calf born the day before on his farm in the Cotswolds. The Albion breed is one of the rarest in the UK.

But that says very little about all the endangered livestock breeds around the world that are fortunately the focus of the work of the International Livestock Research Institute (ILRI).

However . . .

When was the last time—if ever—you watched a TV documentary about the rare (so-called ‘heritage’) varieties of the food plants on which we depend, or their closest wild species relatives, such as the barleys of Ethiopia or the potatoes of the South American Andes, for instance. And would you really care if you hadn’t?

Are you even aware that the barleys that we use for brewing originally came from Ethiopia and the Middle East? Or that the Spanish brought the potato back to Europe in the 16th century from Peru? What about your daily cups of tea or coffee?

These are just some of the myriad of fascinating histories of our food crops. Today many of these staples are often more important in agriculture in parts of the world far distant from the regions where they originated and were first domesticated.

In the UK, enthusiasts will be aware of heritage vegetable varieties, and the many varieties of fruits like apples that have disappeared from commercial orchards, but are still grown at places like Berrington Hall in Herefordshire.

Take a look at this article by freelance communicator Jeremy Cherfas about the origins of the food we eat. Jeremy has written a lot about genetic resources (and many other aspects of sustainable agriculture). As he says, you may discover a few surprises.

In centers of domestication, the diversity of the crops grown by farmers is impressive indeed. It’s wonderful. It’s BEAUTIFUL! The domestication of crops and their use by farmers worldwide is the story of civilization.

Here are just a few examples from beans, maize, cocoa, cucurbits, wheat, and lentil.

And take a look at the video below.

Who could fail to be impressed by such a range of shapes and colors of these varieties? And these varieties (and wild species) contain all the genes we need to keep crops productive.

Plant genetic resources: food for the stomach, food for the soul.


My own work since 1971 concerned the conservation and use of potatoes and rice (and some legume species as side projects).

In Peru, I came to learn just how important potatoes are for communities that live at altitude in the Andes. Could the Inca empire have grown and dominated the region had there been no potatoes (and maize)?

Machu Picchu

And there are so many wild species of potatoes that can be found from the southern USA to the south of Chile and east into the plains of Brazil. The International Potato Center (CIP) in Lima (where I worked for over eight years) has the world’s largest genebank of potato varieties. Important wild species collections are maintained there, as well as in Scotland at the Commonwealth Potato Collection (maintained by the James Hutton Institute), and the USA, at the NRSP-6 Potato Genebank in Sturgeon Bay, WI.

Rice is the food of Asia. There are thousands upon thousands of varieties that grow in standing water, or on sloping uplands, or in areas that flood and so have evolved to elongate rapidly to keep pace with rising flood waters.

Here is a selection of images of rice diversity in Laos, one of the countries that we explored during the 1990s.

Would it have been possible to build the temple complex at Angkor Wat in Cambodia in the 12th century without rice? It has been estimated that upwards of one million workers were employed in its construction. That workforce needed a constant supply of staple rice, the only crop that could be grown productively in this monsoon environment.

These potato and rice examples are the tip of the genetic resources and civilization history iceberg. Think about the origins of agriculture in Turkey and the Mideast, 10,000 years ago. Remains of wheat, barley and pulses like lentil and chickpea have been found at the earliest cities in that region. And these histories are repeated all around the world.


In 1983 and 1984, BBC2 aired two series of a program called Geoffrey Smith’s World of Flowers, in which Smith (a professional gardener and broadcaster) waxed lyrical on the history of many of his favorite garden plants, and their development in cultivation: tulips from Turkey, dahlias from Mexico, lilies from North America, and many, many more.

In these programs, he talked about where and how the plants grow in the wild, when they had been collected, and by whom, and how through decades (centuries in some cases) of hybridization and selection, there are so many varieties in our gardens today. The programs attracted an audience of over 5 million apparently. And two books were also published.

I had an idea. If programs like these could be so popular, how about a series on the food plants that we eat, where they originated, how they were domesticated, and how modern varieties have been bred using these old varieties and wild species. I envisaged these programs encompassing archaeology and crop science, the rise of civilizations, completing the stories of why and which crops we depend on.

I wrote a synopsis for the programs and sent it to the producer at the BBC of the Geoffrey Smith programs, Brian Davies. I didn’t hear back for several weeks, but out of the blue, he wrote back and asking to come up to Birmingham for a further discussion. I pitched the idea to him. I had lots of photos of crop diversity and wild species, stories about the pioneers of plant genetic resources, like Vavilov, Jack Harlan, Erna Bennett, and Jack Hawkes, to name just a few. I explained how these plant stories were also stories about the development and growth of civilizations, and how this had depended on plant domestication. Stories could be told from some of the most important archaeological sites around the world.

Well, despite my enthusiasm, and the producer warming to the idea, he eventually wrote back that the BBC could not embark on such a series due to financial limitations. And that’s all I heard. Nevertheless, I still think that a series along these lines would make fascinating television. Now who would present the series (apart from myself, that is!)?

Maybe its time has come around again. From time-to-time, interesting stories appear in the media about crops and their origins, as this recent one about cocoa and vanilla in the Smithsonian Magazine illustrates.

But we need to do more to spread the plant genetic resources ‘gospel’. The stories are not only interesting, but essential for our agricultural survival.


 

Lentils (and Mrs. Vavilov) on my mind . . .

Nikolai Ivanovich Vavilov (1887-1943)—The Father of Plant Genetic Resources—is one of my scientific heroes. Yet I knew nothing about him until September 1970 when I began my graduate studies concerning the conservation and use of plant genetic resources at The University of Birmingham (in the Department of Botany as it was then).

Last Saturday, 26 January, was the 76th anniversary of Vavilov’s death in a Soviet prison.

Prison photos of Vavilov.

Vavilov’s grave in Saratov.

Botanist, science writer, and broadcaster James Wong (@Botanygeek) posted a short thread of tweets about Vavilov. So, I tweeted a reply to James about three scientists (two I worked with; the other I’d been introduced to) who met Vavilov in the 1930s.

I followed up with another  tweet.

Actually, Elena Barulina (1896-1957) was Vavilov’s second wife who passed away just two years after Vavilov had been ‘rehabilitated’ by the Soviet government, as she was working her way through his various publications.

Vavilov had first married Ekaterina Saharova in 1912, and they had one son, Oleg (born 1918).

Vavilov divorced Ekaterina in 1926 and married Elena; they had one son, Yuri (born 1928). Both Oleg and Yuri became physicists, like their renowned uncle Sergey, Nikolai’s younger brother. Ekaterina died in 1963 never having remarried.

Elena (Helena) Barulina was an international lentil expert, publishing an important monograph in 1930. During the course of 1970-71, I got to know this publication in great detail.

So how did I get involved with lentils, and what was the outcome? As part of the MSc course requirements at Birmingham, each student had to present a short dissertation. I opted to carry out a study of crop variation, but first I had to choose the species for my study.

Trevor Williams

My dissertation supervisor was Dr J Trevor Williams (who went on to become the first Director General of the International Board for Plant Genetic Resources or IBPGR (that then became the International Plant Genetic Resources Institute or IPGRI, and is now Bioversity International) in Rome.

In November 1970, we scanned the pages of Flora Europaea, looking for potential targets among the various legume species. And there, under the cultivated lentil (Lens culinaris) was the important comment: Origin unknown. Now there was a challenge if ever we saw one!

Lentil is an ancient crop, associated with the earliest developments and spread of agriculture in the Near East and Mediterranean, and this is where the wild lentil species are also found. When I began my study, there were just five recognized lentil species (this was increased to seven in a 2015 paper):

  • Lens culinaris (the cultivated species)
  • L. orientalis
  • L. nigricans
  • L. ervoides
  • L. montbretii (now regarded as a species of Vicia)

I presented my dissertation, Studies in the genus Lens Miller with special reference to Lens culinaris Medik., in September 1971, having used Barulina’s monograph as my lentil ‘Bible’ throughout.

I grew a large field trial of lentil varieties and, from my analysis of the variation in morphological characters, some chromatographic analyses, and growth pattern relationships, concluded that the small- and large-seeded forms described by Barulina as subsp. microsperma and subsp. macrosperma were the extremes of a continuous variation pattern, and not correlated with geographical origin. Similar small- and large-seeded forms can also be seen in other legumes like faba bean and grasspea.

To analyze the relationships between the different lentil species, I spent several days working in the Herbarium at the Royal Botanic Gardens at Kew, measuring variation in many morphological characters on as many herbarium specimens of lentil species I could get my hands on. I also borrowed herbarium specimens from several other herbaria. In all I must have looked at least a couple of hundred herbarium sheets.

Hybrid indices for lentil species.

Species were compared by constructing hybrid indices (a numerical method developed and first described in 1949 by renowned American botanist, Edgar Anderson—another scientific hero of mine—in his seminal publication Introgressive Hybridization). This allowed me to determine to what extent variation patterns in lentil species overlapped, or were distinct. Click on the image to the right to see an enlarged version of the resulting hybrid indices.

While the variation patterns between some species were quite distinct, the continuity in variation between L. orientalis and L. culinaris led me to the conclusion that we might be describing a wild species progenitor-domesticate relationship. And, indeed, this is what I proposed in my dissertation.

A year later, the eminent Israeli botanist Daniel Zohary actually published a paper¹ in the scientific journal Economic Botany arriving at the same conclusion. The studies I commenced in 1970-71 were continued by Carmen Sánchez Kilner the following year, and in our 1974 paper we proposed that L. culinaris and L. orientalis were subspecies of the same species, L. culinaris. In 1979, another Israeli botanist, Gideon Ladizinsky, reached the same conclusion based on hybridization experiments and cytogenetic analysis, in a paper published in Euphytica.

Today, I’m sure students would dive straight into analyses of molecular markers to clarify the taxonomy and species relationships. Almost 50 years ago these techniques were not available, so we had to rely on a thorough analysis of species morphology, an approach that is often regarded today as ‘old hat’ but still remains the solid foundation of plant taxonomy. It was an approach that served us well, and our conclusions were corroborated by others later on.

I see my studies on lentils as an important link to Vavilov and his colleagues such as Elena Barulina. Also, in later research, I drew on Vavilov’s Law of Homologous Series and its relevance to potatoes, especially with regard to resistance to the cyst nematode (Globodera spp.).

It’s also interesting to note just how relevant the ‘Vavilov approach’ still is today (76 years after his death), guiding the exploration and use plant genetic resources to increase agricultural productivity, which was the focus of my career over 40 years.

A botanical field trip to the south of Peru . . . 45 years ago

In 1976, a paper appeared in the scientific journal Flora, authored by University of St Andrews botanist Peter Gibbs¹ (now retired), on the breeding system of a tuber crop, oca (Oxalis tuberosa), that is grown by farmers throughout the Andes of Peru and Bolivia.

Like a number of Oxalis species, oca has a particular floral morphology known as heterostyly that promotes outcrossing between different plants. In his 1877 The Different Forms of Flowers on Plants of the Same Species, Charles Darwin had illustrated (in Fig. 11) the particular situation of tristyly in ‘Oxalis speciosa‘, the same floral morphology that is found in oca. In this illustration taken from Darwin’s publication, the ‘legitimate’ pollinations are shown; stigmas can only receive pollen from stamens at the same level in another flower.

Anyway, to cut a long story short, Peter had visited Peru in early 1974 (hard to believe that it’s 45 years ago), made collections of oca from a number of localities, particularly one village, Cuyo Cuyo, in the Department of Puno in the south of Peru (just north of Lake Titicaca), and then studied the breeding system of the oca varieties that he’d collected. His 1976 paper in Flora emanated from that field trip.


But there’s more to that story (and publication) than meets the eye. It was also tied up with the research I was carrying out on potatoes in the Peruvian Andes at that time. Peter and I made that field trip together, spending at least three weeks on the road, before flying back to Lima from Cuzco.

I don’t recall precisely when I first met Peter. We were obviously in touch when planning the trip south, but I simply can’t remember whether, during 1973, Peter had passed through Lima where I was working at the International Potato Center (CIP) in La Molina since January that year, or he had contacted CIP’s Director General Richard Sawyer asking if the center could provide logistical support and the DG had passed that request on to me. Whatever the course of events, Peter and I came to an agreement to make a field trip together to the south of Peru.

This is the route of more than 2000 km that we took.

While working as an Associate Taxonomist at CIP I was also registered for a PhD in potato biosystematics (under potato expert Professor Jack Hawkes at The University of Birmingham) which I was expected to complete by 1975. My work, studying the breeding relationships of potato varieties with different chromosome numbers was similar, in some respects, to that Peter envisaged with oca.

I’d been looking for suitable field locations where it might be possible to study the dynamics of potato cultivation in an ‘unspoiled’ area where mostly traditional potato varieties were cultivated rather than varieties bred and released on the market in recent years. At the back end of 1973 I made a short visit to Puno on the shore of Lake Titicaca to explore several possible field sites. Then, Peter proposed we visit the remote village of Cuyo Cuyo, around 250 km north of Puno. He’d come across a paper (either one by AW Hill in 1939 or another by WH Hodge in 1951 – both are cited by Peter in his Flora paper) that described widespread oca cultivation at Cuyo Cuyo on a series of ancient terraces, but also of potato varieties. I wasn’t sure if this was the location I was looking for, but agreed that we could explore Cuyo Cuyo first before heading north towards Cuzco in search of other likely sites.


Our journey south to Puno took at least three days if memory serves me correctly. Our trusty chariot was a short wheelbase Land Rover, with a canvas hood.

Not the most secure vehicle if you have to park up overnight in an unprotected lot. Nor the most comfortable; very sturdy suspension. But an excellent vehicle otherwise for ‘driving’ out of tricky situations.

We headed south on the Panamericana Sur, stopping at Ica or Nazca on the first night south of Lima, then on the Arequipa on the second day.

The Panamericana hugs the coast through the southern desert, crossing river valleys that flow down from the Andes to meet the Pacific Ocean. Along these, and in the area of Camana (where the road heads inland to Arequipa) quite a lot of rice is grown.

From Arequipa it must have taken another day to travel to Puno across the altiplano.

We then had another night to recoup in Puno, enjoying a comfortable bed, some good food, and perhaps one too many algarrobina cocktails (made from pisco) that Peter had taken a shine to.

Along the shore of Lake Titicaca near Puno


It took a day to travel to Cuyo Cuyo, across the altiplano (>4000 masl), fording rivers, and then, as we approached the village from the south, dropping into a steep-sided valley, the Sandia Gorge.

We hit a cloud layer, obscuring views of the valley, but also coming across a landslide that had to be cleared before we could make progress.

Once past that barrier, the cloud cleared and we began to see something of the majesty of the Cuyo Cuyo valley, with the steep valley sides covered in ancient terraces that, as we discovered over the next few days, were still be farmed communally as they had been for generations apparently. On the descent into Cuyo Cuyo, the banks alongside the road were also covered in masses of a beautiful begonia (Begonia clarkei Hook.) with large white flowers about 3-4 inches in diameter.


Where to stay? There was no hotel or pensión in Cuyo Cuyo. We did however have some camping gear with us such as camp beds, sleeping bags and the like. Plus all our other equipment for collecting (and drying) herbarium samples, and flowers and flower buds for pollen and chromosome studies.

After some enquiries we met Sr Justo Salas Rubín (who was, if I remember correctly, the local postmaster – seen with Peter below) who gave us space in one of the rooms of his home (the ‘post office’?) to set up ‘camp’. We also soon became quite a curiosity for the local children (and some animal friends as well).

I was not disappointed that we chose Cuyo Cuyo first. It was an extraordinary location where we could interact with potato and oca farmers who grew a wide range of varieties, and who were open to collaborate with us. Since that visit in 1974 several other botanists (and anthropologists) have made field studies at Cuyo Cuyo on the agricultural terraces that I described here.

While Peter set about collecting samples in the many oca fields (mainly beside the river on the valley floor), I set off up the terraces to study a couple of fields for their varietal composition, the ploidy (or chromosome number) of these varieties, and the factors that led farmers to accept or reject varieties. I was interested to see how triploid varieties (sterile forms with 36 chromosomes that can only be formed following hybridization between varieties with 48 and 24 chromosomes) could enter farmer systems, and at what frequency.

I also looked at the methods used to cultivate potatoes, and the tools used.²

On the left is a foot plough, about 4 feet in length, known in Cuyo Cuyo as a ‘huire’ (most often ‘chaqui taccla’ in other parts of Peru). Its component parts are: A. ‘calzada’ that rests on the shoulder; B. ‘huiso’ or hand grip; C. ‘lazo’ or leather binding fastening the parts together; D. ‘taquillpo’ or foot rest; and E. the ‘reja’ or blade. On the right is a hand tool used for harvesting potatoes (and presumably oca as well) called the ‘lawccana’, as well as other cultivations during the growing season. Its component parts are: A. the ‘ccalo’ or handle; B. the ‘lazo’, a leather thong holding the blade C. or ‘chonta’ on to the handle.

My paper on potatoes at Cuyo Cuyo was finally published in 1980 in the journal Euphytica. And that’s a tale in itself.³

Peter was keen to make herbarium sheets of many of the varieties he’d collected. We set up a dryer in the house where we were staying. But there was a problem. Most of the samples were pretty wet to begin with, as we experienced intermittent rain during our stay in Cuyo Cuyo. Oca stems are very fleshy, and despite our best efforts, they just didn’t dry out. Even when we got them back to Lima, and Peter prepared them for shipping back to St Andrews, many of the samples were still showing signs of life.

Indeed, after he returned to Scotland, Peter was able to take cuttings from his herbarium samples and grow plants to maturity in the glasshouse, thus continuing his studies there.


After three or four days in Cuyo Cuyo, we retraced our steps to Puno, then headed north towards Cuzco and further study sites near Chinchero.

At these, I was particularly interested in taking flower bud samples from different potato fields. In the area we chose, farmers grew a combination of bred varieties for sale in the local markets of Cuzco and, around their homes, native varieties for home consumption. In this photo, large plantings of commercial varieties stretch into the distance. Around the homes in the foreground, in walled gardens, farmers grew their native varieties.

As I was busy looking at different varieties, these two women came by, and one sat down to breastfeed her baby. They are wearing the traditional dress of that region of Cuzco.

On another day we set out to study potato (and oca) fields a little more remote, so had to hire horses to reach our destination.

Field work complete, Peter and I spent a couple of days resting up in Cuzco before flying back to Lima. We left the Land Rover there for one of my colleagues Zósimo Huamán to pick up, as he planned to undertake some fieldwork as well before driving back to Lima.

During the couple of days in Cuzco we paid a call on Prof. César Vargas, a renowned Peruvian botanist (and close friend of my PhD supervisor Jack Hawkes), who I’d met once before in January 1973 not long after I arrived in Peru. Prof Vargas’s daughter Martha studied for her MSc degree in botany at the University of St Andrews.

L to R: my wife Steph, Peter, and Martha Vargas

All in all, we had a successful field trip to the south of Peru. It’s hard to believe it all took place 45 years ago next month. But it remains, in my mind’s eye, quite a significant trip from the years I spent in Peru.


¹ Peter graduated in botany from the University of Liverpool, and completed his PhD in 1964 there under the supervision of Professor Vernon Heywood, who moved to the University of Reading to become head of that university’s Department of Botany a couple of years later. Peter and I had a lot to talk about, because in 1969-70, when I was an undergraduate at the University of Southampton, Vernon Heywood gave a series of 20 lectures on flowering plant taxonomy over 10 weeks to Southampton botanists, because Leslie Watson, Southampton’s taxonomy lecturer had moved to Australia. Vernon and I renewed our acquaintance some years later, in 1991, when he and I attended a genetic resources meeting at the Food and Agriculture Organization of the United Nations (FAO) in Rome just before I moved to the Philippines to join the International Rice Research Institute (IRRI).

² One interesting piece of information that didn’t make it into my thesis but which I remember clearly was the incidence of geophagy among some residents of Cuyo Cuyo. I was taken to a location where farmers would excavate small quantities of a hard clay, that would be ground to a powder and mixed with water to form a slurry or soft paste. They would then dip recently harvested boiled potatoes in the clay as this, apparently, would decrease the slightly ‘spicy’ flavor of some of the varieties. I’m not sure how widespread this behavior was, but it’s something that has stuck in my mind all these years. I think I once had photos but they are long lost, more’s the pity.

³ I completed my PhD in December 1975, and shortly afterwards moved to Costa Rica to continue working for CIP, in potato breeding and agronomy. I started to prepare three manuscripts from my thesis for publication in Euphytica. The first, on varietal diversity, was submitted in February 1977, and published later the same year. The second, on breeding relationships, was published in 1978, having been submitted in July 1977. The third, on the ethnobotany of potato cultivation in Cuyo Cuyo finally appeared in print in 1980, having been submitted to Euphytica in February 1979.

But Euphytica had not been the first choice for this third paper. I actually produced a manuscript for the journal Economic Botany, and it included more details of the cropping systems and varietal choices made by farmers. My paper was received by the journal and acknowledged, but then I heard nothing more, for months and months. Eventually I wrote to the editor asking about the status of my manuscript. And I received a very strange reply.

It seemed that the editor-in-chief had retired, and his replacement had found, on file, manuscripts that had been submitted up to 20 years earlier, but had never been published! I was asked how I wanted to proceed with my manuscript as there was no guarantee it would appear in print any time soon. But about the same time, I received a nice letter from the then editor of Euphytica, Dr AC Zeven, complimenting me on my PhD thesis (which he had read in the library at Wageningen University in the Netherlands) and encouraging me to publish my work on the ethnobotany of potatoes – if I hadn’t already done so. I withdrew my manuscript from Economic Botany, and after some reformatting to fit the Euphytica style, sent it to Dr Zeven. He requested some deletions of the more descriptive sections on ethnobotany, and published my paper in 1980.


One last thing: I also remember was the novel that Peter was reading throughout the trip. Watership Down by Richard Adams, first published in 1972, that went on to become a literary sensation. I did read it myself at some point, but whether I borrowed Peter’s copy immediately after the trip, or some time later, I don’t recall. I know I didn’t think it would become the phenomenon that it did. What do I know?


 

Discovering Vavilov, and building a career in plant genetic resources: (3) Becoming a genebanker in the 1990s, and beyond

My decision to leave a tenured position at the University of Birmingham in June 1991 was not made lightly. I was about to be promoted to Senior Lecturer, and I’d found my ‘home’ in the Plant Genetics Research Group following the reorganization of the School of Biological Sciences a couple of years earlier.

But I wasn’t particularly happy. Towards the end of the 1980s, Margaret Thatcher’s Conservative Government had become hostile to the university sector, demanding significant changes in the way they operated before acceding to any improvements in pay and conditions. Some of the changes then forced on the university system still bedevil it to this day.

I felt as though I was treading water, trying to keep my head above the surface. I had a significant teaching load, research was ticking along, PhD and MSc students were moving through the system, but still the university demanded more. So when an announcement of a new position as Head of the Genetic Resources Center (GRC) at the International Rice Research Institute (IRRI) in the Philippines landed on my desk in September 1990, it certainly caught my interest. I discussed such a potential momentous change with Steph, and with a couple of colleagues at the university.

Nothing venture, nothing gained, I formally submitted an application to IRRI and, as they say, the rest is history. However, I never expected to spend the next 19 years in the Philippines.


Since 1971, I’d worked almost full time in various aspects of conservation and use of plant genetic resources. I’d collected potato germplasm in Peru and the Canary Islands while at Birmingham, learned the basics of potato agronomy and production, worked alongside farmers, helped train the next generation of genetic conservation specialists, and was familiar with the network of international agricultural research centers supported through the Consultative Group on International Agricultural Research or CGIAR.

What I had never done was manage a genebank or headed a department with tens of staff at all professional levels. Because the position in at IRRI involved both of these. The head would be expected to provide strategic leadership for GRC and its three component units: the International Rice Germplasm Center (IRGC), the genebank; the International Network for the Genetic Evaluation of Rice (INGER); and the Seed Health Unit (SHU). However, only the genebank would be under the day-to-day management of the GRC head. Both INGER and the SHU would be managed by project leaders, while being amalgamated into a single organizational unit, the Genetic Resources Center.

I was unable to join IRRI before 1 July 1991 due to teaching and examination commitments at the university that I was obliged to fulfill. Nevertheless, in April I represented IRRI at an important genetic resources meeting at FAO in Rome, where I first met the incoming Director General of the International Board for Plant Genetic Resources (soon to become the International Plant Genetic Resources Institute or IPGRI), Dr Geoff Hawtin, with whom I’ve retained a friendship ever since.

On arrival at IRRI, I discovered that the SHU had been removed from GRC, a wise decision in my opinion, but not driven I eventually discerned by real ‘conflict of interest’ concerns, rather internal politics. However, given that the SHU was (and is) responsible, in coordination with the Philippines plant health authorities, to monitor all imports and exports of rice seeds at IRRI, it seemed prudential to me not to be seen as both ‘gamekeeper and poacher’, to coin a phrase. After all the daily business of the IRGC and INGER was movement of healthy seeds across borders.


Klaus Lampe

My focus was on the genebank, its management and role within an institute that itself was undergoing some significant changes, 30 years after it had been founded, under its fifth Director General, Dr Klaus Lampe, who had hired me. He made it clear that the head of GRC would not only be expected to bring IRGC and INGER effectively into a single organizational unit, but also complete a ‘root and branch’ overhaul of the genebank’s operations and procedures, long overdue.

Since INGER had its own leader, an experienced rice breeder Dr DV Seshu, somewhat older than myself, I could leave the running of that network in his hands, and only concern myself with INGER within the context of the new GRC structure and personnel policies. Life was not easy. My INGER colleagues dragged their feet, and had to be ‘encouraged’ to accept the new GRC reality that reduced the freewheeling autonomy they had become accustomed to over the previous 20 years or so, on a budget of about USD1 million a year provided by the United Nations Development Program or UNDP.

When interviewing for the GRC position I had also queried why no germplasm research component had been considered as part of the job description. I made it clear that if I was considered for the position, I would expect to develop a research program on rice genetic resources. That indeed became the situation.


Once in post at IRRI, I asked lots of questions. For at least six months until the end of 1991, I made no decisions about changes in direction for the genebank until I better understood how it operated and what constraints it faced. I also had to size up the caliber of staff, and develop a plan for further staff recruitment. I did persuade IRRI management to increase resource allocation to the genebank, and we were then able to hire technical staff to support many time critical areas.

But one easy decision I did make early on was to change the name of the genebank.  As I’ve already mentioned, its name was the ‘International Rice Germplasm Center’, but it didn’t seem logical to place one center within another, IRGC in GRC. So we changed its name to the ‘International Rice Genebank’, while retaining the acronym IRGC (which was used for all accessions in the germplasm collection) to refer to International Rice Genebank Collection.

In various blog posts over the past year or so, I have written extensively about the genebank at IRRI, so I shall not repeat those details here, but provide a summary only.

I realized very quickly that each staff member had to have specific responsibilities and accountability. We needed a team of mutually-supportive professionals. In a recent email from one of my staff, he mentioned that the genebank today was reaping the harvest of the ‘seeds I’d sown’ 25 years ago. But, as I replied, one has to have good seeds to begin with. And the GRC staff were (and are) in my opinion quite exceptional.

In terms of seed management, we beefed up the procedures to regenerate and dry seeds, developed protocols for routine seed viability testing, and eliminated duplicate samples of genebank accessions that were stored in different locations, establishing an Active Collection (at +4ºC, or thereabouts) and a Base Collection (held at -18ºC). Pola de Guzman was made Genebank Manager, and Ato Reaño took responsibility for all field operations. Our aim was not only to improve the quality of seed being conserved in the genebank, but also to eliminate (in the shortest time possible) the large backlog of samples to be processed and added to the collection.

Dr Kameswara Rao (from IRRI’s sister center ICRISAT, based in Hyderabad, India) joined GRC to work on the relationship between seed quality and seed growing environment. He had received his PhD from the University of Reading, and this research had started as a collaboration with Professor Richard Ellis there. Rao’s work led to some significant changes to our seed production protocols.

Since I retired, I have been impressed to see how research on seed physiology and conservation, led by Dr Fiona Hay (now at Aarhus University in Denmark) has moved on yet again. Take a look at this story I posted in 2015.

Screen house space for the valuable wild species collection was doubled, and Soccie Almazan appointed as  wild species curator.

One of the most critical issues I had to address was data management, which was in quite a chaotic state, with data on the Asian rice samples (known as Oryza sativa), the African rices (O. glaberrima), and the remaining 20+ wild species managed in separate databases that could not ‘talk’ to each another. We needed a unified data system, handling all aspects of genebank management, germplasm regeneration, characterization and evaluation, and germplasm exchange. We spent about three years building that system, the International Rice Genebank Collection Information System (IRGCIS). It was complicated because data had been coded differently for the two cultivated and wild species, that I have written about here. That’s a genebank lesson that needs to be better appreciated in the genebank community. My colleagues Adel Alcantara, Vanji Guevarra, and Myrna Oliva did a splendid job, which was methodical and thorough.

In 1995 we released the first edition of a genebank operations manual for the International Rice Genebank, something that other genebanks have only recently got round to.

Our germplasm research focused on four areas:

  • seed conservation (with Richard Ellis at the University of Reading, among others);
  • the use of molecular markers to better manage and use the rice collection (with colleagues at the University of Birmingham and the John Innes Centre in Norwich);
  • biosystematics of rice, concentrating on the closest wild relative species (led by Dr Bao-Rong Lu and supported by Yvette Naredo and the late Amy Juliano);
  • on farm conservation – a project led by French geneticist Dr Jean-Louis Pham and social anthropologists Dr Mauricio Bellon and Steve Morin.

At the beginning of the 1990s there were no genome data to support the molecular characterization of rice. Our work with molecular markers was among use these to study a germplasm collection. The research we published on association analysis is probably the first paper that showed this relationship between markers and morphological characteristics or traits.

In 1994, I developed a 5-year project proposal for almost USD3.3 million that we submitted for support to the Swiss Development Cooperation. The three project components included:

  • germplasm exploration (165 collecting missions in 22 countries), with about half of the germplasm collected in Laos; most of the collected germplasm was duplicated at that time in the International Rice Genebank;
  • training: 48 courses or on-the-job opportunities between 1995 and 1999 in 14 countries or at IRRI in Los Baños, for more than 670 national program staff;
  • on farm conservation to:
    • to increase knowledge on farmers’ management of rice diversity, the factors that
      influence it, and its genetic implications;
    • to identify strategies to involve farmers’ managed systems in the overall conservation of
      rice genetic resources.

I was ably assisted in the day-to-day management of the project by my colleague Eves Loresto, a long-time employee at IRRI who sadly passed away a few years back.

When I joined IRRI in 1991 there were just under 79,000 rice samples in the genebank. Through the Swiss-funded project we increased the collection by more than 30%. Since I left the genebank in 2001 that number has increased to over 136,000 making it the largest collection of rice germplasm in the world.

We conducted training courses in many countries in Asia and Africa. The on-farm research was based in the Philippines, Vietnam, and eastern India. It was one of the first projects to bring together a population geneticist and a social anthropologist working side-by-side to understand how, why, and when farmers grew different rice varieties, and what incentives (if any) would induce them to continue to grow them.

The final report of this 5-year project can be read here. We released the report in 2000 on an interactive CD-ROM, including almost 1000 images taken at many of the project sites, training courses, or during germplasm exploration. However, the links in the report are not active on this blog.

During my 10 year tenure of GRC, I authored/coauthored 33 research papers on various aspects of rice genetic resources, 1 co-edited book, 14 book chapters, and 23 papers in the so-called ‘grey’ literature, as well as making 33 conference presentations. Check out all the details in this longer list, and there are links to PDF files for many of the publications.


In 1993 I was elected chair of the Inter-Center Working Group on Genetic Resources, and worked closely with Geoff Hawtin at IPGRI, and his deputy Masa Iwanaga (an old colleague from CIP), to develop the CGIAR’s System-wide Genetic Resources Program or SGRP. Under the auspices of the SGRP I organized a workshop in 1999 on the application of comparative genetics to genebank collections.

Professor John Barton

With the late John Barton, Professor of Law at Stanford University, we developed IRRI’s first policy on intellectual property rights focusing on the management, exchange and use of rice genetic resources. This was later expanded into a policy document covering all aspects of IRRI’s research.

The 1990s were a busy decade, germplasm-wise, at IRRI and in the wider genetic resources community. The Convention on Biological Diversity had come into force in 1993, and many countries were enacting their own legislation (such as Executive Order 247 in the Philippines in 1995) governing access to and use sovereign genetic resources. It’s remarkable therefore that we were able to accomplish so much collecting between 1995 and 2000, and that national programs had trust in the IRG to safely conserve duplicate samples from national collections.

Ron Cantrell

All good things come to an end, and in January 2001 I was asked by then Director General Ron Cantrell to leave GRC and become the institute’s Director for Program Planning and Coordination (that became Communications two years later as I took on line management responsibility for Communication and Publications Services, IT, and the library). On 30 April, I said ‘goodbye’ to my GRC colleagues to move to my new office across the IRRI campus, although I kept a watching brief over GRC for the next year until my successor, Dr Ruaraidh Sackville Hamilton, arrived in Los Baños.

Listen to Ruaraidh and his staff talking about the genebank.


So, after a decade with GRC I moved into IRRI’s senior management team and set about bringing a modicum of rationale to the institute’s resource mobilization initiatives, and management of its overall research project portfolio. I described here how it all started. The staff I was able to recruit were outstanding. Running DPPC was a bit like running a genebank: there were many individual processes and procedures to manage the various research projects, report back to donors, submit grant proposals and the like. Research projects were like ‘genebank accessions’ – all tied together by an efficient data management system that we built in an initiative led by Eric Clutario (seen standing on the left below next to me).

From my DPPC vantage point, it was interesting to watch Ruaraidh take GRC to the next level, adding a new cold storage room, and using bar-coding to label all seed packets, a great addition to the data management effort. With Ken McNally’s genomics research, IRRI has been at the forefront of studies to explore the diversity of genetic diversity in germplasm collections.

Last October, the International Rice Genebank was the first to receive in-perpetuity funding from the Crop Trust. I’d like to think that the significant changes we made in the 1990s to the genebank and management of rice germplasm kept IRRI ahead of the curve, and contributed to its selection for this funding.

I completed a few publications during this period, and finally retired from IRRI at the end of April 2010. Since retirement I have co-edited a second book on climate change and genetic resources, led a review of the CGIAR’s genebank program, and was honored by HM The Queen as an Officer of the British Empire (OBE) in 2012 for my work at IRRI.

So, as 2018 draws to a close, I can look back on almost 50 years involvement in the conservation and use of plant genetic resources for food and agriculture. What an interesting—and fulfilling—journey it has been.


 

 

 

 

Discovering Vavilov, and building a career in plant genetic resources: (2) Training the next generation of specialists in the 1980s

When, in the mid- to late-60s, Jack Hawkes was planning a one-year MSc course, Conservation and Utilization of Plant Genetic Resources (CUPGR), at the University of Birmingham (in the Department of Botany), Sir Otto Frankel (that doyen of the genetic resources movement) predicted that the course would probably have a lifetime of just 20 years, at most. By then, he assumed, all the persons who needed such training would have passed through the university’s doors. Job done! Well, it didn’t turn out quite that way.

The first cohort of four students graduated in September 1970, when I (and four others) arrived at the university to begin our careers in plant genetic resources. In 1989, the course celebrated its 20th anniversary. But there was still a demand, and Birmingham would continue to offer graduate training (and short course modules) in genetic resources for the next 15 or so years before dwindling applications and staff retirements made the course no longer viable.

Over its lifetime, I guess at least 500 MSc and Short Course students from more than 100 countries received their training in genetic conservation and use. So, for many years, the University of Birmingham lay at the heart of the growing genetic resources movement, and played a pivotal role in ensuring that national programs worldwide had the trained personnel to set up and sustain genetic conservation of local crops and wild species. Many Birmingham graduates went on to lead national genetic resources programs, as evidenced by the number who attended the 4th International Technical Conference on Plant Genetic Resources convened by FAO in Leipzig in June 1996.

Birmingham PGR students at the Leipzig conference in 1996. Trevor Sykes (class of 1969) is wearing the red tie, in the middle of the front row, standing next to Andrea Clausen (Argentina) on his left. Geoff Hawtin, then Director General of IPGRI is fourth from the right (On the back row), and Lyndsey Withers (who gave a course on in vitro conservation to Birmingham students) is second from the right on the front row (standing in between Liz Matos (from Angola) on her left, and the late Rosa Kambuou (Papua New Guinea).


In April 1981, I joined that training effort as a faculty member at the university. For the previous eight years, I had been working for the International Potato Center (CIP) in Peru and Costa Rica. Around September 1980 (a couple months before I left Costa Rica to return to Lima and my next assignment with CIP), I was made aware that a Lectureship had just been advertised in the Department of Plant Biology (as the Department of Botany had been renamed) to contribute to the MSc course curriculum.

Jack Hawkes was due to retire in September 1982 after he reached the mandatory retirement age (for full professors) of 67. He persuaded the university to create a lectureship in his department to cover some of the important topics that he would vacate, primarily in crop diversity and evolution.

After my arrival in Birmingham, I didn’t have any specific duties for first four months. With the intake of the 1981-82 cohort, however, it was ‘full steam ahead’ and my teaching load remained much the same for the next decade. My teaching focused on crop diversity and evolution, germplasm exploration, and agricultural systems, although I made some small contributions to other topics as well.

I also took on the role of Short Course Tutor for those who came to study on one or both of the semester modules (about 12 weeks each).

Since its inception in 1969, the overall structure of the course remained much the same, with about nine months of theory, followed by written examinations. The curriculum varied to some degree over the lifetime of the course, as did the content as new biology opened new opportunities to study, conserve, and use genetic resources.

Following the examinations, all students completed a three-month research project and submitted a dissertation around the middle of September, which was examined by an external examiner. The first external examiner, from 1970-1972, was Professor Norman Simmonds, then Director of the Scottish Plant Breeding Station, and a widely respected plant breeder and potato and banana expert.

Financial support for students came from a variety of sources. The year after I graduated, the course was recognized by one of the UK research councils (I don’t remember which) for studentship support, and annually three or four British students were funded in this way through the 1970s and 80s. By the late 1970s, the International Board for Plant Genetic Resources¹ (IBPGR) funded many of the students coming from overseas, and had also agreed an annual grant to the department that, among other aspects, funded a lectureship in seed physiology and conservation (held by Dr Pauline Mumford). A few students were self-funded.

Here are some of the classes from 1978 to 1988; names of students can be found in this file. Do you recognize anyone?

L: Class of 1978 | R: Class of 1979

L: Class of 1984 | R: Class of 1985

L: Class of 1986 | Class of 1987

L: Class of 1988 | R: Short Course participants, Autumn semester 1987

The first group of students that I had direct contact with, in the autumn of 1981, came from Bangladesh, Germany, Indonesia, Malaysia, Portugal, Turkey, and Uruguay. After nearly 40 years I can’t remember all their names, unfortunately.

The MSc class of 1982: L-R: Ghani Yunus (Malaysia), ?? (Uruguay), Rainer Freund (Germany), Ayfer Tan (Turkey), Dr Pauline Mumford (IBPGR-funded lecturer), ?? (Bangladesh), ?? (Bangladesh), Maria Texeira (Portugal), ?? (Indonesia).

Over the decade I remained at Birmingham, I must have supervised the dissertation projects of about 20-25 students, quite an intensive commitment during the summer months. Since my main interest was crop diversity and biosystematics, several students ran projects on potatoes and Lathyrus. I curated the Hawkes collection of wild potato species, and had also assembled a large collection of Lathyrus species from different countries and diverse environments. Some students wanted to work on crops and species important in their countries and, whenever possible, we tried to accommodate their interests. Even with glasshouse facilities it was not always possible to grow many tropical species at Birmingham². In any case, the important issue was for students to gain experience in designing and executing projects, and evaluating germplasm effectively. Two students from Uganda for example, studied the resistance of wild potatoes from Bolivia to the potato cyst nematode, in collaboration with the Nematology Department at Rothamsted Experiment Station.

Several students stayed on to complete PhD degrees under my supervision, or jointly supervised with my colleague Professor Brian Ford-Lloyd (who was the MSc Course Tutor), and I have written more about that here.

Immediately on joining the department in 1981, Jack asked me to take on the supervision of two of his students, Lynne Woodwards and Adi Damania who were half way through their research. Lynne competed her study of the non-blackening trait in a tetraploid (2n=4x=48 chromosomes) wild potato species from Mexico, Solanum hjertingii in 1982. Adi split his time between Birmingham and the Germplasm Institute in Bari, Italy, where he was co-supervised by Professor Enrico Porceddu, studying barley and wheat landraces from Nepal and Yemen. One of the methods he used was the separation of seed proteins using gel electrophoresis. His PhD was completed in 1983.

Lynne’s research on Solanum hjertingii was continued by Ian Gubb, in collaboration with the Institute of Food Research in Norwich.

Two Peruvian students, Rene Chavez (1978) and Carlos Arbizu (1979) completed their PhD theses in 1984 and 1990 respectively. They did all their experimental work at CIP in Lima, studying wide crosses in potato breeding, and wild potatoes as sources of virus resistance.

Malaysian student Ghani Yunus (1982) returned to Birmingham around 1986 to commence his PhD and continued his study of the grasspea (Lathyrus sativus) that he began for his MSc dissertation.


While the MSc course comprised my main teaching load, I also had some undergraduate teaching commitments. I did no First Year teaching, thank goodness! In the Summer Semester I had a 50% commitment to a Flowering Plant Taxonomy module as part of the Second Year Plant Biology stream. I also gave half a dozen lectures on agricultural systems as part of a Second Year Common Course attended by all Biological Sciences students, and I eventually became chair of that course.

With Brian, we offered a Third (Final) Year option in conservation and use of genetic resources under the Plant Biology degree. I guess during the 1980s some 40 students (maybe more) chose that option. The five-week module comprised about 20-25 lectures, and each student also had to undertake an practical project as well. It was quite a challenge to devise and supervise so many ‘doable’ projects during such a short period.


While all this was going on, I also had a couple of research projects on potatoes. The first, on true potato seed, was in collaboration with CIP in Peru and the Plant Breeding Institute in Cambridge. Over the project’s five-year life, I traveled to Lima at least once a year. This also gave me an opportunity to check on progress of my PhD students there.

In another project (with Brian) funded by industry, we investigated the opportunity for using somaclonal variation to identify genotypes resistant to low temperature sweetening in potatoes. The research had an important spin-off however for the genetic conservation of vegetatively-propagated crops like potatoes, as we demonstrated that genetic changes do occur during in vitro or tissue culture.

Knowing of my annual trips to Peru, the chocolate and confectionery manufacturers in the UK asked me to scope the possibility of establishing a field genebank in Peru of cacao (cocoa) trees in the northeast of the country. The industry had funded a project like this in Ecuador, and wanted to replicate it in Peru. Regrettably, the security situation deteriorated markedly in Peru (due to the Shining Path or Sendero Luminoso terrorist group), and the project never went ahead.


Brian and I collaborated a good deal during the 1980s, in teaching, research, and publishing.

Around 1983 he and I had the idea of writing a short general text about genetic resources and their conservation. As far as we could determine there were no books of this nature suitable for both undergraduates and postgraduates. Having approached the publisher Edward Arnold, we set about putting our ideas down on paper. The book appeared in 1986, with a print run of 3000, which quickly sold out. After Edward Arnold was taken over by Cambridge University Press, our modest volume was re-issued in a digitally printed version in 2010.

In 1988, we organized the first International Workshop on Plant Genetic Resources at Birmingham, on in situ conservation. The topic of the second two-day workshop, in April 1989, focused on climate change and genetic resources. We were ahead of our time! Proceedings from the workshop were published by Belhaven Press in 1990. It was a theme that my co-editors and I returned to in 2014, published by CAB International.


Around 1989, however, I was becoming increasingly disillusioned with university life, and had begun to think about seeking other opportunities, although none seemed to come along. Until September 1990, that is. One morning, I received in the mail a copy of a recruitment announcement for Head of the Genetic Resources Center at the International Rice Research Institute (IRRI) in the Philippines. To this day I have no idea who sent me this announcement, as there was no cover note.

Nothing ventured, nothing gained, I decided to submit my application. After all, IRRI was a sister center of CIP, and I was very familiar with the international agricultural research centers funded through the Consultative Group on International Agricultural Research (CGIAR).

Personally, I knew it would be a huge opportunity, but also a challenge for Steph and our two daughters Hannah (13) and Philippa (9). But apply I did, and went for an interview at the beginning of January 1991, learning three weeks later that I was the preferred candidate of three interviewed. All three of us were ex-Birmingham MSc and PhD, having completed our theses under the supervision of Jack Hawkes. My ‘rivals’ were managing genebanks in the UK and Nigeria. I had no genebank experience per se.

I was about to become a genebanker, but I couldn’t join the institute quite as early as IRRI management desired. I still had teaching and examination commitments to fulfill for that academic year, which would not be finished until the end of June. Nevertheless, IRRI did ask me to represent the institute at a meeting in April of the Commission on Plant Genetic Resources at the Food and Agriculture Organization (FAO) in Rome, the first of many that I would attend over the next decade.

Friday 28 June was my last day at the university. Two days later I was on my way to Manila, to open the next chapter of my genetic resources adventure.


¹ Around 1990, IBPGR became the International Plant Genetic Resources Institute (IPGRI), and later, Bioversity International, expanding its headquarters in Rome.

² One of the students in my 1970-71 class, Folu Ogbe from Nigeria, undertook a project on West African rice and part of one glasshouse was converted to a ‘rice paddy’!


 

 

Discovering Vavilov, and building a career in plant genetic resources: (1) Starting out in South America in the 1970s

Nikolai Vavilov

Russian geneticist and plant breeder Nikolai Vavilov (1887-1943) is a hero of mine. He died, a Soviet prisoner, five years before I was born.

Until I began my graduate studies in the Department of Botany at the University of Birmingham in the conservation and use of plant genetic resources (i.e., crops and their wild relatives) almost 50 years ago in September 1970, his name was unknown to me. Nevertheless, Vavilov’s prodigious publications influenced the career I subsequently forged for myself in genetic conservation.

Jack Hawkes

At the same time I was equally influenced by my mentor and PhD supervisor Professor Jack Hawkes, at Birmingham, who met Vavilov in St Petersburg in 1938.

Vavilov undoubtedly laid the foundations for the discipline of genetic resources —the collection, conservation, evaluation, and use of plant genetic resources for food and agriculture (PGRFA). It’s not for nothing that he is widely regarded as the Father of Plant Genetic Resources.

Almost 76 years on from his death, we now understand much more about the genetic diversity of crops than we ever dreamed possible, even as recently as the turn of the Millennium, thanks to developments in molecular biology and genomics. The sequencing of crop genomes (which seems to get cheaper and easier by the day) opens up significant opportunities for not only understanding how diversity is distributed among crops and species, but how it functions and can be used to breed new crop varieties that will feed a growing world population struggling under the threat of environmental challenges such as climate change.

These tools were not available to Vavilov. He used his considerable intellect and powers of observation to understand the diversity of many crop species (and their wild relatives) that he and his associates collected around the world. Which student of genetic resources can fail to be impressed by Vavilov’s theories on the origins of crops and how they varied among regions.

In my own small way, I followed in Vavilov’s footsteps for the next 40 years. I can’t deny that I was fortunate. I was in the right place at the right time. I had some of the best connections. I met some of the leading lights such as Sir Otto Frankel, Erna Bennett, and Jack Harlan, to name just three. I became involved in genetic conservation just as the world was beginning to take notice.


Knowing of my ambition to work overseas (particularly in South America), Jack Hawkes had me in mind in early 1971 when asked by Dr Richard Sawyer, the first Director General of the International Potato Center (CIP, based in Lima, Peru) to propose someone to join the newly-founded center to curate the center’s collection of Andean potato varieties. This would be just a one-year appointment while a Peruvian scientist received MSc training at Birmingham. Once I completed the MSc training in the autumn of 1971, I had some of the expertise and skills needed for that task, but lacked practical experience. I was all set to get on the plane. However, my recruitment to CIP was delayed until January 1973 and I had, in the interim, commenced a PhD project.

I embarked on a career in international agricultural research for development almost by serendipity. One year became a lifetime. The conservation and use of plant genetic resources became the focus of my work in two international agricultural research centers (CIP and IRRI) of the Consultative Group on International Agricultural Research (CGIAR), and during the 1980s at the University of Birmingham.


My first interest were grain legumes (beans, peas, etc.), and I completed my MSc dissertation studying the diversity and origin of the lentil, Lens culinaris whose origin, in 1970, was largely speculation.

Trevor Williams

Trevor Williams, the MSc Course tutor, supervised my dissertation. He left Birmingham around 1977 to become the head of the International Board for Plant Genetic Resources (IBPGR) in Rome, that in turn became the International Plant Genetic Resources Institute (IPGRI), and continues today as Bioversity International.

Joe Smartt

I guess that interest in legume species had been sparked by Joe Smartt at the University of Southampton, who taught me genetics and encouraged me in the first instance to apply for a place to study at Birmingham in 1970.

But the cold reality (after I’d completed my MSc in the autumn of 1971) was that continuing on to a PhD on lentils was never going to be funded. So, when offered the opportunity to work in South America, I turned my allegiance to potatoes and, having just turned 24, joined CIP as Associate Taxonomist.

From the outset, it was agreed that my PhD research project, studying the diversity and origin, and breeding relationships of a group of triploid (with three sets of chromosomes) potato varieties that were known scientifically as Solanum x chaucha, would be my main contribution to the center’s research program. But (and this was no hardship) I also had to take time each year to travel round Peru and collect local varieties of potatoes to add to CIP’s germplasm collection.

I explored the northern departments of Ancash and La Libertad (with my colleague Zósimo Huamán) in May 1973, and Cajamarca (on my own with a driver) a year later. Each trip lasted almost a month. I don’t recall how many new samples these trips added to CIP’s growing germplasm collection, just a couple of hundred at most.

In February 1974, I spent a couple of weeks in the south of Peru, in the department of Puno, studying the dynamics of potato cultivation on terraces in the village of Cuyo-Cuyo.

I made just one short trip with Jack Hawkes (and another CIP colleague, Juan Landeo) to collect wild potatoes in central Peru (Depts. of Cerro de Pasco, Huánuco, and Lima). It was fascinating to watch ‘the master’ at work. After all, Jack had been collecting wild potatoes the length of the Americas since 1939, and instinctively knew where to find them. Knowing their ecological preferences, he could almost ‘smell out’ each species.

My research (and Zósimo’s) contributed to a better understanding of potato diversity in the germplasm collection, and the identification of duplicate clones. During the 1980s the size of the collection maintained as tubers was reduced, while seeds (often referred to as true potato seed, or TPS) was collected for most samples.

Roger Rowe

Dr Roger Rowe was my department head at CIP, and he became my ‘local’ PhD co-supervisor. A maize geneticist by training, Roger joined CIP in July 1973 as Head of the Department of Breeding & Genetics. Immediately prior to joining CIP, he led the USDA’s Inter-Regional Potato Introduction Project IR-1(now National Research Support Program-6, NRSP-6) at the Potato Introduction Station in Sturgeon Bay, Wisconsin.

Although CIP’s headquarters is at La Molina on the eastern outskirts of Lima, much of my work was carried out in Huancayo, a six hour drive winding up through the Andes, where CIP established its highland field station. This is where we annually grew the potato collection.

During the main growing season, from about mid-November to late April  (coinciding with the seasonal rainfall), I’d spend much of every week in Huancayo, making crosses and evaluating different varieties for morphological variation. This is where I learned not only all the practical aspects of conservation of a vegetatively-propagated crop, and many of the phytosanitary implications therein, but I also learned how to grow a crop of potatoes. Then back in Lima, I studied the variation in tuber proteins using a tool called polyacrylamide gel electrophoresis (that, I guess, is hardly used any more) by separating these proteins across a gel concentration gradient, as shown diagrammatically in the so-called electrophoregrams below. Compared to what we can achieve today using a range of molecular markers, this technique was really rather crude.

Jack Hawkes visited CIP two or three times while I was working in Lima, and we would walk around the germplasm collection in Huancayo, discussing different aspects of my research, the potato varieties I was studying, and the results of the various crossing experiments.

With Jack Hawkes in the germplasm collection in Huancayo in January 1975 (L); and (R), discussing aspects of my research with Carlos Ochoa in a screenhouse at CIP in La Molina (in mid-1973).

I was also fortunate (although I realized it less at the time) to have another potato expert to hand: Professor Carlos Ochoa, who joined CIP (from the National Agrarian University across the road from CIP) as Head of Taxonomy.

Well, three years passed all too quickly, and by the end of May 1975, Steph and I were back in Birmingham for a few months while I wrote up and defended my dissertation. This was all done and dusted by the end of October that year, and the PhD was conferred at a congregation held at the university in December.

With that, the first chapter in my genetic resources career came to a close. But there was much more in store . . .


I remained with CIP for the next five years, but not in Lima. Richard Sawyer asked me to join the center’s Regional Research Program (formerly Outreach Program), initially as a post-doctoral fellow, the first to be based outside headquarters. Thus, in April 1976 (only 27 years old) I was posted to Turrialba, Costa Rica (based at a regional research center, CATIE) to set up a research project aimed at adapting potatoes to warm, humid conditions of the tropics. A year later I was asked to lead the regional program that covered Mexico, Central America, and the Caribbean.

CATIE had its own germplasm collections, and just after I arrived there, a German-funded project, headed by Costarrican scientist Dr Jorge León, was initiated to strengthen the ongoing work on cacao, coffee, and pejibaye or peach palm, and other species. Among the young scientists assigned to that project was Jan Engels, who later moved to Bioversity International in Rome (formerly IBPGR, then IPGRI), with whom I have remained in contact all these years and published together. So although I was not directly involved in genetic conservation at this time, I still had the opportunity to observe, discuss and learn about crops that had been beyond my immediate experience.

It wasn’t long before my own work took a dramatically different turn. In July 1977, in the process of evaluating around 100 potato varieties and clones (from a collection maintained in Toluca, Mexico) for heat adaptation (no potatoes had ever been grown in Turrialba before), my potato plots were affected by an insidious disease called bacterial wilt (caused by the pathogen Ralstonia solanacearum).

(L) Potato plants showing typical symptoms of bacterial wilt. (R) An infected tuber exuding the bacterium in its vascular system.

Turrialba soon became a ‘hot spot’ for evaluating potato germplasm for resistance against bacterial disease, and this and some agronomic aspects of bacterial wilt control became the focus of much of my research over the next four years. I earlier wrote about this work in more detail.

This bacterial wilt work gave me a good grounding in how to carefully evaluate germplasm, and we went on to look at resistance to late blight disease (caused by the fungus Phytophthora infestans – the pathogen that caused the Irish Potato Famine of the 1840s, and which continues to be a scourge of potato production worldwide), and the viruses PVX, PVY, and PLRV.

One of the most satisfying aspects of my work at this time was the development and testing of rapid multiplication techniques, so important to bulk up healthy seed of this crop.

My good friend and seed production specialist colleague Jim Bryan spent a year with me in Costa Rica on this project.

Throughout this period I was, of course, working more on the production side, learning about the issues that farmers, especially small farmers, face on a daily basis. It gave me an appreciation of how the effective use of genetic resources can raise the welfare of farmers and their families through the release of higher productivity varieties, among others.

I suppose one activity that particularly helped me to hone my management skills was the setting up of PRECODEPA in 1978, a regional cooperative potato project involving six countries, from Mexico to Panama and the Dominican Republic. Funded by the Swiss, I had to coordinate and support research and production activities in a range of national agricultural research institutes. It was, I believe, the first consortium set up in the CGIAR, and became a model for other centers to follow.

I should add that PRECODEPA went from strength to strength. It continued for at least 25 years, funded throughout by the Swiss, and expanding to include other countries in Central America and the Caribbean.

However, by the end of 1980 I felt that I had personally achieved in Costa Rica and the region as much as I had hoped for and could be expected; it was time for someone else to take the reins. In any case, I was looking for a new challenge, and moved back to Lima (38 years ago today) to discuss options with CIP management.

It seemed I would be headed for pastures new, the southern cone of South America perhaps, even the Far East in the Philippines. But fate stepped in, and at the end of March 1981, Steph, daughter Hannah (almost three) and I were on our way back to the UK. To Birmingham in fact, where I had accepted a Lectureship in the Department of Plant Biology.


The subsequent decade at Birmingham opened up a whole new set of genetic resources opportunities . . .


 

 

Three score and ten . . .

18 November 1948. Today is my 70th birthday. Septuagenarian. The Biblical three score and ten (Psalm 90:10)!

Steph and I have come away for the weekend to celebrate my birthday with The Beatles in Liverpool.

We are staying for a couple of nights at Jurys Inn close to the Albert Dock. Later this morning we’ve booked to visit the National Trust-owned Beatles’ Childhood Homes (of John Lennon and Paul McCartney). And after lunch, we will tour The Beatles Story where I’m hoping to see, displayed there, something special from my childhood.

How the years have flown by. Just a month ago, Steph and I celebrated our 45th wedding anniversary. And I find it hard to believe that I started university over 50 years ago.

That got me thinking. I’ve written quite a lot in this blog about the years after I graduated, my time working overseas, about travel, and what Steph and I have been up to since retiring in 2010.

However, I written much less about my early years growing up in Cheshire and Staffordshire. This is then an appropriate moment to fill some gaps.

A son of Cheshire
I was born in Knowlton House nursing home in Congleton, Cheshire (map), third son and fourth and youngest child of Frederick Harry Jackson (aged 40), a photo process engraver, and Lilian May Jackson, also aged 40, housewife.

Mum and Dad, around 1959/60 after we had moved to Leek

My eldest brother Martin has been able to trace our family’s ancestry (mainly on my father’s side) back to someone named Bull, who was my 13th great-grandfather, born around 1480 on the Staffordshire/ Derbyshire border, just one of my 32,000 plus direct ancestors then. I must be related to royalty in one way or another (as are most of us), although looking at the occupations noted for many of them in various official documents (birth and marriage certificates, census data), we came a long way down the pecking order. Definitely below the salt! We’re Irish on my mother’s side of the family.

A punk before it was fashionable!

I am also a child of the National Health Service (NHS) that was founded in July 1948. In fact, I’m (approximately) the 190,063rd baby born under the NHS!

Knowlton House on Parson Street in Congleton – it’s no longer a nursing home.

I wonder who assisted at my birth? It could well have been our family Dr Galbraith, or Nurses Frost and Botting.

Dr Galbraith (R) was our family doctor, who (with his partner Dr Ritchie) often attended births at Knowlton House, and is seen here with resident midwife Nurse Rose Hannah Frost, who assisted at more than 3000 births. There is a very good chance either Nurse Frost or Nurse May Botting (who ran the nursing home) assisted at my birth. In this photo from 1936, Dr Galbraith and Nurse Frost are holding the Nixon triplets. Photo courtesy of Alan Nixon, who was apparently named after Dr Galbraith.

My dad registered my birth¹ on 22 November (Entry No. 442). There are few ‘Michaels’ in the family; Thomas is my paternal grandfather’s name.

My eldest brother Martin was born in September 1939, just a couple of days before war was declared on Germany. My sister Margaret was born in January 1941. Martin and Margaret spent much of WWII with my paternal grandparents in rural Derbyshire. My elder brother Edgar (‘Ed’) is, like me, one of the baby boomer generation, born in July 1946.

The difference of around 55 years – 1951/52 and 2006

I’ve often wondered what sacrifices Mum and Dad had to make to give us all such a good start in life.

Growing up in Congleton, we lived at 13 Moody Street, close to the town center’s High Street.

There’s not much to tell about my first couple of years, other than what I can surmise from a few photographs taken around that time when I was still in my pram or just beginning to walk. Two things I do remember clearly, though. The hens my father used to keep, and even the large henhouse he constructed at the bottom of the garden. And our female cat, Mitten, and all her kittens. That must have been the start of becoming an ailurophile (cat lover).

My best friend was Alan Brennan, a year younger, who lived a little further up Moody Street at No. 23 (and with whom I reconnected through this blog, after a gap of around 60 years!).

With Alan and his parents (and friends) at Timbersbrook, in 1955. I clearly remember Mr Brennan’s Vauxhall car – a Wyvern I believe.

We didn’t go to the same primary school. Like my brothers and sister before me, I was enrolled (in September 1952 or April 1953, maybe as late as September 1953) at the small Church of England school on Leek Road in Mossley, south of the town. By then, Martin had moved on to grammar school in Macclesfield; Margaret had also transferred to secondary school in Congleton.

Each morning, Ed and I would catch the bus in the High Street together for the short, 1½ mile ride to Mossley. And even as young as five, I would sometimes walk home alone from school during the summer months, along Leek Road and Canal Road/Street. How times change!

I remember the headteacher, Mr Morris, as a kind person. My class teachers were Mrs Bickerton (on the left) and Mrs Johnson (on the right). Courtesy of Liz Campion.

There was a real community of children around Moody Street, Howie Lane/Hill, and Priesty Fields. In summer, we’d all wander up to play on the swing bridge over the Macclesfield Canal (beyond the cemetery – where we would also play in a WWII air raid shelter). The bridge has long been replaced, but from comments on a Congleton Facebook group I belong to, it seems that over the generations, many children enjoyed the swing bridge as much as we did.

In winter, we had fun in the snow at Priesty Fields just round the corner from Moody St. And, as you can see below, we enjoyed dressing up. Happy days!

Alan Brennan is the little by to the left of the ‘clown’, and in front of the ‘pirate’, my elder brother Ed. The lower image was taken on May Day, probably 1953 or 54. I’m on the left, carrying the sword, uncertain whether to be a knight or a cowboy.

I often joined my father when he went out on photographic assignments for the Congleton Chronicle (where he was Chief Photographer), often to Biddulph Grange when it was an orthopedic hospital, also to Astbury, and out into the beautiful Cheshire countryside.

I remember one outing in particular, to Little Moreton Hall in May 1954. This is my father’s photo of Manley Morris Men dancing there, an image that stuck in my mind for many years. So much so that when I went to university in the later 1960s, I helped form a morris dancing side, the Red Stags, that’s still going strong (albeit in a slightly different form) 50 years later.

For family holidays I remember those in North Wales, at a caravan park or, on one occasion, a camping coach, a converted railway carriage alongside the mainline to Holyhead next to the beach at Abergele.

During these early years, until July 1954, rationing was still in place that had come into effect at the start of the Second World War. I often wonder how my parents managed to raise four children during these difficult years. One thing I do recall, however, is how we shared things, particularly confectionery. No individual treats. My father would buy a Mars bar (I’m sure they were bigger then) and cut it into six pieces. Funny how these things stick in one’s memory.


The move to Leek
April 1956. A big change in my life. My family upped sticks and moved 12 miles southeast to the market town of Leek in north Staffordshire, where my father took over a retail photography business. As I was only 7½ when we moved, I’ve come to regard Leek as my home town. My parents lived there for the rest of their lives. My father passed away in 1980, and after my mother had a stroke in 1990, only then did she move away from Leek to spend her last couple of years in a care home near my sister in South Wales.

We lived at No. 65, St Edward Street, and within a couple of days of arriving there, I’d made friends with three boys who lived close by: Philip Porter (next door), Geoff Sharratt – whose father was publican at The Quiet Woman pub a few doors away, and David Phillips who lived over the road. Geoff’s younger sister Susan sometimes joined in our games, as did Philip’s sister Jill. We were the ‘St Edward Street Gang’.

Here we are in the late 1950s (probably 1958), in the yard of The Quiet Woman pub. L-R: Sue, Geoff, me, Philip, and Dave. And again in 2018.

Geoff was my best friend, and we spent a lot of time playing together. There were several upstairs rooms at The Quiet Woman, one of which was the Lodge of the Royal Antediluvian Order of Buffaloes (RAOB, the Buffs, a fraternal organization somewhat similar to the Freemasons). During inclement weather, we often took refuge in the Lodge, playing among the benches and high chairs.

I was also a cub scout, as was Ed.

Around 1960, the lease on No. 65 came due, so my father decided to to find a better location for his business. First, he moved across St Edward’s St to No. 56 (while we lived in a flat at the top of the Market Place). In 1962/63 my father acquired No. 19 Market Place as premises for his photographic business, with living accommodation above. This was just what he had been looking for, centrally located in the town, lots of footfall. But the whole property had to be refurbished; there was only one water tap – in the cellar. He did much of the refurbishment himself. I’ve never ceased to be amazed at his DIY talents, something I sadly have not inherited to the same degree. My parents remained at No. 19 until they retired in 1976.

Sandwiched between Jackson the Optician (no relation) on the left, and Victoria Wine on the right, No 19 Market Place was my parents home for 14 years.

Around the same time, Geoff’s parents left The Quiet Woman and moved elsewhere in the town. I was also traveling every day to school to Trent Vale on the south side of Stoke-on-Trent (a round trip of about 28 miles), while Geoff continued his education in Leek. As a consequence, we drifted apart, but through my blog we reconnected in 2012.
