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.
