When the late Professor Jack Hawkes was appointed to a lectureship in botany at the University of Birmingham in 1952, he had already been working on potatoes for more than a decade. And immediately prior to arriving in Birmingham he’d spent three years in Colombia helping to establish a national potato breeding program. From then until his retirement in 1982 – and indeed throughout the 1980s – Birmingham was an important center for potato studies.
The potato germplasm that Hawkes collected (with EK Balls and W Gourlay in the 1938-39 expedition to South America) eventually formed the basis of the Empire then Commonwealth Potato Collection, maintained at the James Hutton Institute in Scotland. Throughout the 50s, 60s, 70s, and 80s Jack also had a large collection of wild potato (Solanum) species at Birmingham. This was a special quarantine collection; in the 1980s for potato quarantine purposes, Birmingham was effectively outside the European Union! For more than two decades Jack was assisted by horticultural technician Dave Downing, seen in the photo below. At the end of the 1980s we decided to donate the seed stocks from Jack’s collection to the Commonwealth Potato Collection, and it went into quarantine in Scotland. As the various lines were tested for viruses diseases they were introduced into the main collection. Jack used this collection to train a succession of PhD students on the biosystematics of potatoes. I continued with this tradition after I joined the University of Birmingham in 1981. My first student graduated in 1982 (after I had taken over supervision from Jack).
Here is the list of University of Birmingham PhD students who worked on potatoes, as far as I can remember. All of them from 1975 (with the exception of Ian Gubb) had also attended the MSc course on genetic resources:
Richard Lester (UK), 1962. Taught at Makerere University in Uganda, before joining the Dept. of Botany at Birmingham in 1969. Retired in 2002, and died in 2006. Studied the biochemical systematics of Mexican wild Solanum species. The species Solanum lesteri is named after him.
Richard Tarn (UK), 1967. Emigrated to Canada in 1968, and joined Agriculture Canada as a potato breeder in Fredericton, New Brunswick. Retired in 2008. Studied the origin of ploidy levels in wild species.
Katsuo Armando Okada (Argentina), 1970 (?). Retired. Was with IBPGR for a while in the 1980s (?) in Colombia. Studied the origin of Solanum x rechei from Argentina.
Phillip Cribb (UK), 1972. He joined the Royal Botanic Gardens – Kew, and became a renowned orchid taxonomist. Studied the origin of the tetraploid Solanum tuberosum ssp. andigena.
Mike Jackson (UK), 1975. Studied the triploid cultigen Solanum x chaucha. Joint with CIP and Roger Rowe.
David Astley (UK), 1975. Became the curator of the vegetable genebank at Wellesbourne (now the Warwick Crop Centre). Studied the Bolivian wild species Solanum sucrense. The species S. astleyi is named after Dave.
Zosimo Huaman (Peru), 1976. He returned to the International Potato Center (CIP) in Lima, and continued working with the germplasm collection until December 2000; he then began work with several NGOs on biodiversity issues in Peru. Studied the origin of the diploid cultigen Solanum x ajanhuiri. Joint with CIP and Roger Rowe.
Peter Schmiediche (Germany), 1977. He continued working with CIP as a potato breeder (for resistance to bacterial wilt), and was later CIP’s regional leader based in Indonesia. Now retired and sharing his time between Texas (where his children settled) and his native Berlin. Studied the bitter potatoes Solanum x juzepczukii (3x) and S. x curtilobum (5x). Joint with CIP and Roger Rowe.
Luis Lopez (Colombia), 1979. Studied wild species in the Series Conicibaccata.
Lenny Taylor (UK), late 1970s. I don’t remember his thesis topic, but I think it had something to do with tetraploid forms. He joined the Potato Marketing Board (now the Potato Council) but I’ve lost contact.
Lynne Woodwards (UK), 1982. Studied the Mexican tetraploid Solanum hjertingii, which does not show enzymic blackening in cut tubers.
Rene Chavez (Peru), 1984. He returned to the University of Tacna, Peru, but also spent time at CIAT in Cali, Colombia studying a large wild cassava (Manihot spp.) collection. He sadly died of cancer a couple of years ago. Studied wide crossing to transfer resistance to tuber moth and potato cyst nematode. Joint with CIP and Peter Schmiediche.
Elizabeth Newton (UK), 1987? Studied sexually-transmitted viruses in potato. Joint with former CIP virologist Roger Jones (now at the University of Western Australia) at the MAFF Harpenden Laboratory.
Denise Clugston (UK), 1988. Studied embryo rescue and protoplast fusion to use wild species in potato breeding.
Carlos Arbizu (Peru), 1990. An expert on minor Andean tuber crops, he came from the University of Ayacucho. Spent time working in the germplasm program at CIP. Studied the origin and value of resistance to spindle tuber viroid in Solanum acaule. Joint with CIP and principal virologist Luis Salazar (who gained his PhD while studying at the Scottish Crop Research Institute in Dundee).
Ian Gubb (UK), 1991. Studied the biochemical basis of non-blackening in Solanum hjertingii. Joint with the Food Research Institute, Norwich.
Susan Juned (UK), 1994. Now a sustainable technology consultant, Sue is an active local government councillor, and has stood for election to parliament on a couple of occasions for the Liberal Democrats. Studied somaclonal variation in potato cv. Record; this commercial contract research was commissioned by United Biscuits.
David Tay (Malaysia), 2000. He worked in Australia and then was Director of the USDA Ornamental Plant Germplasm Center in Columbus, Ohio, but returned to CIP as head of the genetic resources unit in 2007. He’s now left CIP. I think he worked on diploid cultivated species. Joint with CIP. Not sure why his PhD is dated 2000, as he’d been in CIP in the late 70s.
I also supervised several MSc students who completed dissertations on potatoes (Reiner Freund from Germany, and Beatrice Male-Kayiwa and Nelson Wanyera from Uganda).
The Birmingham link with CIP is rather interesting. In the early 70s, staff at CIP seemed to have a graduate degree in the main from one of four universities: Cornell, North Carolina State, Wisconsin, or Birmingham.
Besides the Birmingham PhD students who went on to work at CIP, my wife Stephanie (MSc 1972, who had been working with the Commonwealth Potato Collection from November 1972 – June 1973 when it was still based at the Scottish Plant Breeding Station – now closed) joined the Breeding and Genetics Dept. at CIP in July 1973.
Roger Rowe, who had been in charge of the US potato genebank in Sturgeon Bay, Wisconsin, also joined CIP in July 1973 as head of the Breeding and Genetics Dept. He co-supervised (with Jack Hawkes) a number of Birmingham PhD students.
With the closure of Jack’s collection at Birmingham we were able to develop other potato research ideas since there were no longer any quarantine restrictions. In 1984 we secured funding from the Overseas Development Administration (now the Department for International Development – DfID) to work on single seed descent (SSD) from diploid potatoes to produce true potato seed (TPS). Diploids are normally self-incompatible, but evidence from a range of species had shown that such incompatibility could be broken and transgressive segregants selected. The work was originally started in collaboration with the Plant Breeding Institute (PBI) in Cambridge, but when the Thatcher government privatized the PBI and sold it to Monsanto in 1988, we continued the work at Birmingham. After a further year we hit a ‘biological brick wall’ and decided that the resources needed would be too great to warrant continued effort. This paper reflects our philosophy on TPS . Another paper  spells out the approach we planned.

I was wondering if Rene chavez hd published his work on Cyste nemaotde resistance and wrote his name on google and this araticle of so many people i know came up.. well done mike!!
HI Maria – just type ‘CIP’ in the search box and I think you’ll find a lot more to interest you. I’ll send you details of Rene’s cyst nematode work.
Hi, Dr Jackson. Greetings from Sarawak. I chanced upon your blog and this particular page has brought back such a lot of memories. I’m from the 1984 batch at University of Birmingham together with Nelson Wanyera who’s mentioned above. I look forward to reading your many interesting articles in my free time. It’s good to be able to reconnect through this. Hope this finds you well.
Hi Yen Nyuk, How wonderful to hear from you. I’ve often wondered what you were up to, as with all my former students. I will send you an email. Mike 🙂
Hi Sir Mike Jackson, you wrote wonderful. It would be an honor for me to tell you that I am grand daughter of Dr. Altaf ur Rehman. You made me cry, as you wrote beautifully about your whole journey of university of Birmingham with my grand father. He was my mentor. I can’t explain my feelings, and it will be my honor for me to talk to you.
I will wait for your reply….
