Collaboration between food security institutions and research organizations has contributed to improvements in global grain production that have benefitted millions of farmers around the world – and must continue today. This message was highlighted during a ceremony hosted by the International Maize and Wheat Improvement Center (CIMMYT) to recognize the legacy of World Food Laureate and former CIMMYT Wheat Program Director Sanjaya Rajaram.

The ceremony, held at the CIMMYT Experimental Station in Toluca, State of Mexico, officially dedicated the Station in honor of Sanjaya Rajaram, honoring his memory as an “enemy of world hunger” and one of the scientists who has most contributed to global food security.

The Indian-born naturalized Mexican researcher, who was the third person from CIMMYT to receive the World Food Prize, was recognized for having developed more than 480 high-yielding and adaptable wheat varieties that have been planted on approximately 58 million hectares around the world.

“For this impressive achievement, which seems easy to summarize in one sentence, Raj became a giant of the ‘right to food’ and one of the fiercest enemies of hunger in the world,” said CIMMYT Director General Bram Govaerts.

“Building on the work of Dr. Norman Borlaug, Dr. Sanjaya Rajaram was a driving force in making CIMMYT into the extraordinary institution that it is today,” said Claudia Sadoff, Managing Director, Research Delivery and Impact of CGIAR, a global research partnership of which CIMMYT is a member.

“The challenges of today compel us to redouble our efforts to breed more resilient and more nutritious crops, as Dr. Sanjaya Rajaram did, Sadoff added. “This ceremony reminds us that Dr Rajaram’s legacy and the ongoing efforts of CIMMYT and CGIAR scientists must answer that.”

Awards for international cooperation in food security

At the event, CIMMYT presented awards to the Secretary of Foreign Affairs of Mexico, Marcelo Ebrard Casaubón, and of Secretary of Agriculture and Rural Development (SADER), Víctor Villalobos Arámbula, for their promotion of food security and social inclusion in Mexico and Latin America.

The Secretary of Foreign Affairs of Mexico expressed his gratitude for the Norman E. Borlaug and reaffirmed his commitment to “work in the international arena as we have done, but now we will have to work harder, with greater intensity.”

The Secretary of Agriculture and Rural Development of Mexico, Víctor Villalobos Arámbula, emphasized that Mexico, Latin America and CIMMYT play an important role in the struggle to improve the conditions of small-scale farmers and the resilience of agri-food systems, noting that more than 300,000 farmers grow maize, wheat and associated crops on over one million hectares in Mexico using sustainable technologies from the CIMMYT-led MasAgro project, now called Crops for Mexico.

“Throughout this administration,” he said, “we have designed, implemented and refined, through collaboration between SADER and CIMMYT, sustainable development strategies with a systemic approach that facilitates the participation of producers in more integrated and efficient value chains both in Mexico and in other countries.”

India’s Ambassador to Mexico, Pankaj Sharma, highlighted that his nation owes a large part of its Green Revolution to the “Sonora” wheat variety, which was developed in Mexico, a country that is considered one of the cradles of agriculture at a global level, with arable land accounting for 15 percent of the total land dedicated to agriculture in the world.

Report on the results of the Crops for Mexico initiative

CIMMYT’s Wheat Germplasm Bank Curator and Genotyping Specialist Carolina Sansaloni presented highlighted impacts from Crops for Mexico, the main cooperative project between the Government of Mexico — through the Secretary of Agriculture and Rural Development — and CIMMYT, and a flagship initiative in the application of technologies in sustainable agriculture.

The project has been in operation for more than a decade in 28 states in Mexico, with the collaboration of more than 100 national and international partners and private and public sector agencies in 12 regions, offering research infrastructure and training development for sustainable agronomic practices, she explained.

She reported that the results of 40 platforms, 500 demonstration modules and two thousand extension areas have an impact on more than one million hectares and benefit 300,000 maize, wheat and bean producers, with the use of high-yield varieties.

Rosalinda Muñoz Tafolla, a maize farmer in Amacuzac, in the Mexican state of Morelos, explained that her drive to produce healthy food led her to participate in Crops for Mexico, where CIMMYT’s support and advice has enabled her to dramatically increase her farm’s productivity while protecting the soil and conserving natural resources.

She explained that with the conservation agriculture system she learned to improve soil conditions, planted a new maize variety, and was supported in marketing her harvest at a good price and selling 2,000 maize ears (mostly weighing 200 grams each).

CIMMYT to dedicate historic wheat experimental station to Sanjaya Rajaram

Written by Marcia MacNeil on March 18, 2021. Posted in News.

The International Maize and Wheat Improvement Center (CIMMYT) will rename one of its most historic and successful wheat experimental stations in honor of Sanjaya Rajaram, a former Wheat Program director, distinguished scientist and World Food Prize laureate.

Rajaram, one of the most successful and influential wheat breeders ever, passed away in Mexico on February 17, 2021. The wheat experimental station managed by CIMMYT in Toluca, Mexico, will be renamed “Centro Experimental Sanjaya Rajaram” in his honor.

Rajaram joined CIMMYT in 1969, working alongside Nobel Prize Laureate and scientist Norman Borlaug in Mexico. Recognizing his talent and initiative, Borlaug appointed Rajaram as head of CIMMYT’s wheat breeding program when he was 29 years old. His career accomplishments include overseeing the development of more than 480 high-yielding, disease-resistant wheat varieties, which are sown today on 58 million hectares in 51 countries.

The wheat experimental station is located on the outskirts of Mexico’s fifth largest city, Toluca, about 60 kilometers southwest of Mexico City. It is a key testing location in the shuttle breeding process that Borlaug developed in the 1960s in his quest for high-yielding wheat to avert global famine — a breeding process that successfully continues to this day. It is also the site where Borlaug famously received news of his 1970 Nobel Peace Prize win.

“Dr. Rajaram was a world-renowned wheat breeder and scientist and a true hunger fighter. In 2014, he was recognized with one of the highest honors in agriculture, the World Food Prize, in acknowledgement for improving the lives of hundreds of millions of people through his work on high-yielding and disease-resistant wheat varieties grown on more than 58 million hectares throughout the world,” said CIMMYT Director General Martin Kropff. “He was an inspiring and cherished presence at CIMMYT for 40 years. His loss is felt by all of us and I am delighted to be able to honor him this way.”

“It is only fitting that a wheat experimental station crucial to Borlaug’s pioneering work be named for Dr. Rajaram, who followed in his footsteps,” said CIMMYT Chief Operating Officer, Deputy Director General for Research, and Integrated Development Program Director Bram Govaerts.

A virtual event to remember Rajaram and officially dedicate the Toluca station in his honor is tentatively planned for May.

New greenhouse honors scientist, aims to further maize wild relatives research

Written by Natasha Nagarajan on April 2, 2020. Posted in Features. 1 Comment on New greenhouse honors scientist, aims to further maize wild relatives research

On February 27, 2020, the International Maize and Wheat Improvement Center (CIMMYT) opened a new greenhouse at its research station in Tlaltizapán, in Mexico’s state of Morelos. The Garrison Wilkes Center for Maize Wild Relatives is named after a pioneering scientist in the field of maize genetics.

“The name teosinte refers to a group of wild relatives of maize,” said Denise Costich, manager of the maize germplasm collection at CIMMYT. “The seven members of this group — all in the genus Zea — are more grass-like than maize, produce hard-shelled seeds that are virtually inedible, and are capable of enduring biotic and abiotic stressors better than their crop relative.” Teosintes must be protected, Costich explained, as they possess some desirable qualities that could help improve maize resilience in difficult conditions. Since CIMMYT’s Germplasm Bank is the global source for teosinte seed, the new greenhouse, designed exclusively for the regeneration of teosinte accessions from the bank collection, will ensure that there will always be seed available for research and breeding.

Garrison Wilkes was one of the first scientists to emphasize the importance of the teosintes and their close biological relationship to maize. He spent more than 50 years working on maize conservation in collaboration with CIMMYT. Together with scientists such as Angel Kato, a former CIMMYT research assistant and longtime professor, Suketoshi Taba, former head of CIMMYT’s Germplasm Bank, and Jesus Sanchez, as researchers at the University of Guadalajara, he contributed to the development of the global maize collection of CIMMYT’s Germplasm Bank as it exists today.

Keeping seeds alive

Teosintes are the wild plants from which maize was domesticated about 7,000 years ago. They are durable, with natural resistance to disease and unfavorable weather, and grow primarily in Mexico, Guatemala, Honduras and Nicaragua. “What makes [teosinte] a wild plant is its seed dispersal. Corn doesn’t disperse its seed — it’s stuck on the cob. To be a wild plant means they can sow their own seed and survive,” explained Wilkes. Keeping these seeds alive could be the key to developing resilient modern maize with the potential to feed millions.

One of the difficulties in growing maize and teosinte in Tlaltizapán to produce seed for global distribution is that the station is surrounded by sugarcane fields. Sugarcane carries a disease called the Sugarcane Mosaic Virus (SCMV), to which maize and teosinte are susceptible, and SCMV-positive seed cannot be distributed outside of Mexico. Additionally, if teosinte and maize are grown in close proximity to one another, it becomes very difficult to control gene flow between them via airborne pollen. Several experiments, ranging from growing the teosinte in pots to monitoring that the maize and teosinte flower at different times, could not fully guarantee that there was no cross-contamination. Therefore, in order to continue to cultivate maize and teosinte within the same station, the CIMMYT Germplasm Bank needed to create an isolated environment.

On average, the teosinte seed collections in the germplasm bank were nearly 19 years old, and 29% were not available for distribution due to low seed numbers. Researchers needed to find a way to produce more high-quality seed and get started as soon as possible. “My staff and I visited Jesus Sanchez, a world-renowned teosinte expert, and learned as much as we could about how to cultivate teosinte in greenhouses,” explained Costich “We realized that this could be the solution to our teosinte regeneration problem.”

Construction of the new greenhouse began in late 2017, with funding received from the 2016 Save a Seed Campaign — a crowdfunding initiative which raised more than $50,000. Donations contributed to activities such as seed storage, tours and educational sessions, seed collection, seed repatriation and regeneration of depleted seeds. With the new greenhouse, CIMMYT scientists can now breed teosinte without worrying about maize contamination, and prevent the extinction of these valuable species.

CIMMYT holds most of the world’s publically accessible collections of teosinte. “The wild relatives are a small part of our collection, but also a very important part, as they are theoretically the future of genetic diversity,” said Costich.“They have been important in the evolution of the crop. If we lose them, we can’t learn anything more from them, which would be a shame.”
