As scientists study and learn more about the complicated genetic makeup of the wheat genome, one chromosomal segment has stood out, particularly in efforts to breed high-yielding wheat varieties resistant to devastating and quickly spreading wheat diseases.

Known as the 2NvS translocation, this segment on the wheat genome has been associated with grain yield, tolerance to wheat stems bending over or lodging, and multiple-disease resistance.

Now, thanks to a new multi-institution study led by wheat scientist Liangliang Gao of Kansas State University, we have a clearer picture of the yield advantage and disease resistance conferred by this chromosomal segment for wheat farmers — and more opportunities to capitalize on these benefits for future breeding efforts.

The Aegilops ventricosa 2NvS segment in bread wheat: cytology, genomics and breeding, published in Theoretical and Applied Genetics, summarizes the collaborative effort by scientists from several scientific institutions — including International Maize and Wheat Improvement Center (CIMMYT) head of global wheat improvement Ravi Singh and wheat scientist Philomin Juliana —  to conduct the first complete cytological characterization of the 2NvS translocation.

A rich background

The 2NvS translocation segment has been very valuable in disease-resistance wheat breeding since the early 1990s. Originally introduced into wheat cultivar VPM1 by the French cytogeneticist Gerard Doussinault in 1983 by crossing with a wild wheat relative called Aegilops ventricosa, the segment has been conferring resistance to diseases like eye spot (Pch1 gene), leaf rust (Lr37 gene), stem rust (Sr38 gene), stripe rust (Yr17 gene), cereal cyst (Cre5 gene), root knot (Rkn3 gene) and wheat blast.

The high-yielding blast-resistant CIMMYT-derived varieties BARI Gom 33 and WMRI#3 (equivalent to Borlaug100),released in Bangladesh to combat a devastating outbreak of wheat blast in the region, carry the 2NvS translocation segment for blast resistance.

Earlier research by Juliana and others found that the proportion of lines with the 2NvS translocation had increased by 113.8% over seven years in CIMMYT’s international bread wheat screening nurseries: from 44% in 2012 to 94.1% in 2019. It had also increased by 524.3% in the semi-arid wheat screening nurseries: from 15% in 2012 to 93.7% in 2019. This study validates these findings, further demonstrating an increasing frequency of the 2NvS translocation in spring and winter wheat breeding programs over the past two decades.

New discoveries

The authors of this study completed a novel assembly and functional annotation of the genes in the 2NvS translocation using the winter bread wheat cultivar Jagger. They validated it using the spring wheat cultivar CDC Stanley and estimated the actual size of the segment to be approximately 33 mega base pairs.

Their findings substantiate that the 2NvS region is rich in disease resistance genes, with more than 10% of the 535 high-confidence genes annotated in this region belonging to the nucleotide-binding leucine-rich repeat (NLR) gene families known to be associated with disease resistance.  This was a higher number of NLRs compared to the wheat segment of the Chinese Spring reference genome that was replaced by this segment, adding further evidence to its multiple-disease resistant nature.

In addition to being an invaluable region for disease resistance, the study makes a strong case that the 2NvS region also confers a yield advantage.  The authors performed yield association analyses using yield data on lines from the Kansas State University wheat breeding program, the USDA Regional Performance Nursery —comprising lines from central US winter wheat breeding programs — and the CIMMYT spring bread wheat breeding program, and found a strong association between the presence of the segment and higher yield.

Global benefits

The yield and disease resistance associations of the 2NvS genetic segment have been helping farmers for years, as seen in the high proportion of the segment present in the improved wheat germplasm distributed globally through CIMMYT’s nurseries.

“The high frequency of the valuable 2NvS translocation in CIMMYT’s internationally distributed germplasm demonstrates well how CIMMYT has served as a key disseminator of lines with this translocation globally that would have likely contributed to a large impact on global wheat production,” said study co-author Juliana.

Through CIMMYT’s distribution efforts, it is likely that national breeding programs have also effectively used this translocation, in addition to releasing many 2NvS-carrying varieties selected directly from CIMMYT distributed nurseries.

With this study, we now know more about why the segment is so ubiquitous and have more tools at our disposal to use it more deliberately to raise yield and combat disease for wheat farmers into the future.

The global network safeguarding the world’s wheat

The new interactive map allows visitors to visually explore the milestones that allowed a global network of researchers to fight threats to wheat production.
The new interactive map allows visitors to visually explore the milestones that allowed a global network of researchers to fight threats to wheat production.

In 2005, preeminent wheat breeder and Nobel Laureate Norman E. Borlaug sounded the alarm to bring the world’s attention to the outbreak of a new variant of stem rust, Ug99, that threatened to wipe out 80% of the world’s wheat.

The result was the Borlaug Global Rust Initiative (BGRI), a global community that pioneered innovative ways for scientists and smallholder farmers around the globe to collaborate on meeting challenges brought about by wheat disease and climate change.

As a founding member of BGRI, the International Maize and Wheat Improvement Center (CIMMYT) and, later, the CGIAR Research Program on Wheat, played a crucial role in the core work of the initiative. They led breeding and large-scale international testing to develop disease resistant wheat varieties, coordinated closely with longstanding national partners to facilitate the release and spread of the varieties to farmers, and contributed to critical disease monitoring and tracking initiatives.

The BGRI has documented these efforts and related resources in a newly released interactive story map: Inside the global network safeguarding the world’s wheat from disease and climate change. The map highlights the BGRI’s efforts from 2005 to 2020 to introduce climate-resilient, disease-resistant wheat to resource-constrained wheat growers around the world, especially in sub-Saharan Africa and South Asia.

When a disease threatens to destroy the world’s most important food crop, who do you call?

The map highlights work undertaken by scientists on the front lines of the Durable Rust Resistance in Wheat (DRRW) and Delivering Genetic Gain in Wheat (DGGW) projects from 2005 to 2020. These achievements formed the foundation for the work that continues today under the auspices of the CIMMYT-led  Accelerating Genetic Gains In Maize and Wheat for Improved Livelihoods (AGG) project.

BGRI scientists from more than 22 national and international agricultural research centers infused resilience into wheat and largely staved off large-scale rust epidemics, working with farmers in East Africa, South Asia and other important bread baskets of the world. The BGRI community improved breeding pipelines, created the world’s most sophisticated pathogen surveillance network, increased capacity in germplasm testing nurseries while conserving and sharing genetic resources, and training new generations of young scientists.

Through videos, photos, interviews, journal articles, blogs, news stories and other resources, the map allows visitors to explore the multifaceted work from hunger fighters in Australia, Canada, China, Ethiopia, India, Kenya, Mexico, Nepal, Russia, the United Kingdom, the United States and other countries.

Written and produced by BGRI cinematographer Chris Knight and associate director for communications Linda McCandless, the map is linked to multimedia and resources from contributors around the world.

Wheat breeders from across the globe took a big step towards modernizing their molecular breeding skills at a recent workshop sponsored by the Wheat Initiative, with the CGIAR Excellence in Breeding Platform (EiB) and the International Maize and Wheat Improvement Center (CIMMYT).

The workshop focused on three open-source tools used in molecular breeding: GOBii-GDM for genomic data management, Flapjack for data visualization and breeding analysis, and Galaxy for Genomic Selection. These tools help breeders make selections more quickly and precisely, and ultimately lead to more cost effective and efficient improvement of varieties.

The Wheat Initiative — a global scientific collaboration whose goals are to create improved wheat varieties and disseminate better agronomic practices worldwide — and its Breeding Methods and Strategies expert working group had planned to host these trainings during the 2020 Borlaug Global Rust Initiative Technical Workshop in the United Kingdom. After it became obvious that in-person trainings were not possible, the course organizers — including CIMMYT molecular wheat breeder Susanne Dreisigacker and EiB Adoption Lead and former GOBii project director Elizabeth Jones — decided to come together to host online workshops.

Many of the tools will be incorporated into EiB’s Enterprise Breeding System (EBS), a new integrated data management system being developed for CGIAR breeders. Jones plans to also design training modules for these molecular breeding tools that will be accessible to anyone through the EiB Toolbox.

In the meantime, the tools used in the workshop are all freely available: DArTView, Flapjack (training videos), GOBii-GDM (request access through the web form or by email), and Galaxy Genomic Selection.

The first session of the workshop “Transforming Wheat Breeding Through Integrated Data Management with GOBii and Analysis in Flapjack” benefited breeders from Australia, Canada, Ethiopia, France, India, Ireland, Italy, Morocco, Pakistan, Switzerland, Tunisia, the United Kingdom and the United States.

Powering data analysis around the world

The workshop series, “Transforming Wheat Breeding Through Integrated Data Management with GOBii and Analysis in Flapjack,” aimed to benefit breeders from wheat producing countries all over the world, with sessions over two different time zones spread out over three days to reduce “Zoom fatigue.” Participants joined the first session from Australia, Canada, Ethiopia, France, India, Ireland, Italy, Morocco, Pakistan, Switzerland, Tunisia, the United Kingdom and the United States.

“It was wonderful to see the diversity of participants that we were able to train through an online workshop, many of whom otherwise might not have been able to travel to the UK for the original meeting,” said Jones. “Participants were very engaged, making the workshop so rewarding.”

The workshop was guided by Teresa Saavedra, Wheat Initiative coordinator. Apart from Dreisigacker and Jones, other trainers explained specific tools and approaches. Iain Milne from the James Hutton Institute in Scotland gave more details about the Flapjack genotyping visualization tool, which includes analysis for pedigree verification, marker assisted backcrossing and forward breeding. Andrew Kowalczyk, developer at Diversity Arrays Technology, spoke about the genotyping data QC tool DArTView.

Clay Sneller, wheat breeder at Ohio State University, contributed training materials for important molecular breeding tools. Carlos Ignacio, previously based at the International Rice Research Center (IRRI) and now working on a PhD in Genomic Selection at Ohio State University, contributed his experience as a GOBii team member and a major contributor towards the design of Flapjack tools. Star Gao, application specialist with GOBii and now a requirements analyst for the Enterprise Breeding System, also facilitated the sessions.

Gilles Charmet, research director at the France’s National Research Institute for Agriculture, Food and Environment (INRAE), introduced the sessions in the Americas/Europe time zone with welcome remarks and overview of the goals of the Wheat Initiative. Alison Bentley, director of the CIMMYT Global Wheat Program, briefed on the achievements and goals of the CIMMYT Wheat program and the Accelerating Genetic Gains in Maize and Wheat for Improved Livelihoods (AGG) project.

“This training will contribute towards us reaching our AGG goals of accelerating gains in wheat, by sharing technical knowledge, and allowing our beneficiary partners to have state-of-the-art know-how in the use of genetic and genomic data,” Bentley said.

Participant Stéphane Boury from Caussade Semences, France commented, “This was a very effective way to learn about new tools in wheat breeding.”

The sessions continue in Australasia next week, and will be introduced by Peter Langridge, chair of the Scientific Board for the Wheat Initiative, and EiB director Michael Quinn. Sanjay Kumar Singh, incoming chair of the Breeding expert working group for the Wheat Initiative, will close the event.

With great sorrow, we report the passing of Sanjaya Rajaram, former Wheat Program director and distinguished scientist at the International Maize and Wheat Improvement Center (CIMMYT), in Mexico on February 17, 2021, at the age of 78. Rajaram was one of the most successful and influential wheat breeders ever, and was distinguished with the World Food Prize in 2014.

As leader of bread wheat breeding and later director of CIMMYT’s Global Wheat Program, Rajaram — affectionately known by his colleagues as “Raj” — personally oversaw the development of more than 480 high-yielding, disease-resistant varieties sown on 58 million hectares in 51 countries, increasing global wheat production by more than 200 million tons during his lifetime in diverse regions across the globe.

“At CIMMYT, we all remember Raj as a great and humble colleague helping the team to perform at the highest levels of science with impact. Many of us within CIMMYT, as well in national programs worldwide, have been inspired by him,” said Martin Kropff, CIMMYT Director General. “We will also remember him as a friend who cared for others and treated all people alike.”

“Dr. Rajaram built a generation of wheat breeders at CIMMYT, ICARDA and national research institutions, who are carrying on his legacy and ensuring that new wheat varieties continue to reach farmers. We will deeply miss his presence and encouragement,” said Ravi Singh, head of the Wheat Improvement program once led by Rajaram.

A life devoted to wheat breeding

Born on a small farm in India in 1943, Rajaram studied genetics and plant breeding at the Indian Agricultural Research Institute in New Delhi. After receiving his Ph.D. from the University of Sydney, he joined CIMMYT in 1969, diligently working as a wheat breeder 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 at just 29 years of age.

Borlaug described Rajaram as “a scientist of great vision who made a significant contribution to the improvement of world wheat production, working for the benefit of hundreds of thousands of farmers in countries across the globe.”

Among Rajaram’s many accomplishments include being awarded the prestigious World Food Prize in 2014 for his role in increasing global wheat production and alleviating world hunger. His crossing of spring and winter wheat varieties led to new advances in wheat varieties that were stable across a wide range of environments, as well as featuring high yields and resistance to wheat diseases, particularly rust and foliar blight.

In 2015, he was awarded the Pravasi Bharatiya Samman award, the highest honor conferred on Indians overseas. He also received the highly prestigious Padma Shri award from the government of India in 2001, the Friendship Award from the government of China in 1998, numerous fellowships from scientific societies and doctorates from various universities.

Rajaram recognized the importance of sharing his knowledge and cultivating the talents of the next generation of plant scientists, training and mentoring more than 700 scientists from developing countries worldwide.

Rajaram also served as Director of the Integrated Gene Management Program at the International Center for Agricultural Research in the Dry Areas (ICARDA) before formally retiring in 2008. In his retirement, he continued as a special scientific advisor to CIMMYT and ICARDA, residing in his home of Mexico.

In addition to his successful career as a plant scientist, Rajaram launched and operated Resource Seeds International, a company to study and market seed of improved wheat varieties.

The CIMMYT community sends our deepest condolences to Rajaram’s family during this period.

Heat and Drought Wheat Improvement Consortium (HeDWIC)

The Heat and Drought Wheat Improvement Consortium (HeDWIC) is a global research and capacity building network that takes wheat research from the theoretical to the practical by incorporating the best science into real-life breeding scenarios.

By harnessing the latest technologies in crop physiology, genetics and breeding, HeDWIC makes it easier for wheat scientists to work together on solutions to the complex problems of heat and drought adaptation, contributing to the development of new, climate-resilient wheat varieties for farmers. HeDWIC-associated scientists examine current breeding material and collections held in germplasm banks and apply genomic and phenomic tools to identify novel diversity for heat, drought adaptative traits. This results in novel pre-bred lines in terms of genetic diversity for key stress-adaptive traits suitable for use in breeding programs and/or re-selection as cultivars.

The consortium delivers these lines to public and private wheat programs worldwide via the International Wheat Improvement Network (IWIN) — coordinated for more than half a century by the International Maize and Wheat Improvement Center (CIMMYT) — as international public goods whose global impacts are well documented. Through PhD sponsorships and other opportunities for involvement in research, HeDWIC also provides hands-on training to young scientists, preparing a new generation of crop experts to tackle the pressing issues of crop adaptation under future climate scenarios.

HeDWIC adds value to developing more climate-resilient wheat varieties by:

  • Facilitating global coordination of wheat research related to heat and drought stress in partnership with the Wheat Initiative.
  • Developing research and breeding technologies in response to the priorities of stakeholders: researchers, breeders, farmers, seed companies, national programs, and funding organizations.
  • Connecting geographically and agro-climatically diverse sites for rigorous testing of promising concepts.
  • Curating data resources for use by the global wheat research community.
  • Accelerating the deployment of new knowledge and strategies for developing more climate resilient wheat.
  • Preparing a new generation of promising young scientists from climate-affected regions to tackle crop improvement challenges faced by their own countries.
  • Building additional scientific capacity of wheat researchers in a coordinated fashion that enables a faster response to productivity threats associated with climate change.
  • Enabling farmers to adapt to wheat production in a hotter and drier climate faster due to the coordinated effort and synergy lent by HeDWIC.

HeDWIC is directly funded by the Foundation for Food and Agriculture Research (FFAR) and is supported by in-kind contributions from IWIN, the Bill & Melinda Gates Foundation/UK Foreign, Commonwealth and Development Office (FCDO)-funded Accelerating Genetic Gains in Maize and Wheat for Improved Livelihoods (AGG) project, the CGIAR Research Program on Wheat (WHEAT), the International Wheat Yield Partnership, the Wheat Initiative’s AHEAD, and many international partners who support research and capacity building activities through ongoing collaboration.

It also builds on decades of breeding and collaborative research under abiotic stress coordinated by CIMMYT, with support from agencies including Mexico’s Secretariat of Agriculture and Rural Development (SADER), the CGIAR Trust Fund —in particular the Australian Centre for International Agricultural Research (ACIAR), the UK Foreign, Commonwealth and Development Office (FCDO), and the US Agency for International Development (USAID) — Australia’s Grains Research Development Corporation (GRDC), Germany’s Ministry of Agriculture (BMEL), the Bill & Melinda Gates Foundation, the US Department of Agriculture (USDA), and others.

Lightbulb moments

The challenges facing our food system are growing, both in size and in complexity. In order to tackle these issues and meet the needs of our changing world, the International Maize and Wheat Improvement Center (CIMMYT) understands the importance of assembling a workforce that is diverse, creative and representative. In addition to encouraging STEM careers and hiring more women in scientific positions, we must also foster a more encouraging scientific community for women whose careers are just sparking.

Whether it is through a school field trip, a first internship or a PhD thesis project, CIMMYT is committed to encouraging young women to step into the lab and the fields, and up to the challenge, as we strive to create a more equitable community. On the International Day of Women and Girls in Science, we are inspired by the words of some of the many brilliant women whose scientific careers are just beginning, lighting the pathway to a more equitable future.

The International Day of Women and Girls in Science is particularly meaningful to CIMMYT’s new Global Wheat Program (GWP) Director, Alison Bentley. Listen and watch as she tells her story, from her first lightbulb moment on a high school field trip, to a leadership position in the wheat research world.

In celebration of the International Day of Women and Girls in Science, CIMMYT is participating in a unique marathon event, carrying a global conversation with CGIAR women scientists that are leading change and creating solutions to some of the world’s biggest challenges.

Powered by Women in Research and Science (WIRES), a new employee-led resource group at CGIAR, the event will showcase the many ways women scientists are transforming the way we look at our food, land and water systems around the world. In addition to learning about cutting-edge science, you’ll be able to engage with inspiring speakers in 13 different countries.

Australia’s High Commissioner to India, Barry O’Farrell, visited the Borlaug Institute for South Asia (BISA) in Ludhiana, India, on January 20, 2021 along with his delegation.

O’Farrell acknowledged the historic role of the International Maize and Wheat Improvement Center (CIMMYT) sharing the seeds of the most recent, climate-resilient, high-yielding, and disease-resistant wheat genotypes. He also appreciated that this work is being continued with even greater vigor by BISA for the benefit of India and the whole of South Asia.

The High Commissioner was happy to note that wheat germplasm is freely shared with public and private sector national partners under constant guidance and collaboration with the Indian Council of Agricultural Research (ICAR) and the Department of Agriculture Research and Education (DARE).

O’Farrell emphasized the strong collaboration between Indian and Australian research institutes. He called for even more cross-learning between scientists and other stakeholders for research, policy and capacity development in the areas of land, water, climatic resilience, environmental sustainability and germplasm enhancement for the benefit of farmers of both countries.

Witnessing science in action

Arun Kumar Joshi, CIMMYT Regional Representative for Asia and Managing Director of BISA, welcomed the group and briefed the visitors on CIMMYT and BISA’s collaboration with ICAR and DARE.

H.S. Sidhu, Principal Research Engineer at BISA, and M.L. Jat, Principal Scientist and Systems Agronomist at CIMMYT, presented the major challenges and research outputs related to climate change, the food-energy-water nexus and the overall agricultural sustainability challenges faced by India.

One of the successful examples of collaboration between Australia and India is the Happy Seeder, which addresses these challenges through conservation agriculture and sustainable intensification. O’Farrell saw the expansive wheat fields sown with the Happy Seeder and was impressed by the technology.

The group also discussed the evidence-based policy changes that have taken place, as well as future strategies for accelerated impact through new approaches, like carbon farming. A detailed discussion took place on climate-smart agriculture research, with a focus on precision water and nutrient management using digital agriculture technologies and their complementarity for boosting Happy Seeder uptake.

The High Commissioner and his delegation also visited the wheat breeding program, where CIMMYT researcher Uttam Kumar explained the development of wheat genotypes — in collaboration with ICAR-DARE and the national agriculture research system — for a range of environments, management conditions, and against various stresses, with the ultimate objective of serving the needs of smallholder farmers.

O’Farrell also appreciated the BISA-designed Phenocart for high-throughput precision phenotyping in wheat improvement. O’Farrell highlighted and appreciated that this season, BISA is conducting the largest wheat breeding trial in South Asia: currently more than 60,000 plots are planted at the BISA station in Ludhiana alone.

Ravi Singh, Distinguished Scientist and Head of Global Wheat Improvement at the International Maize and Wheat Improvement Center (CIMMYT), has received the highest honor conferred by the Government of India to non-resident Indians.

The Pravasi Bharatiya Samman Award recognizes outstanding achievements by non-resident Indians, persons of Indian origin, or organizations or institutions run by them either in India or abroad. Awardees are selected for their support to India’s causes and concerns by a committee led by the Vice President and the Minister of External Affairs of India. The awardees, according to the awards website, “represent the vibrant excellence achieved by our diaspora in various fields.” The online award announcement ceremony took place on January 9, 2021, with India’s President Ram Nath Kovind as a chief guest.

Ravi Singh, whose career at CIMMYT spans 37 years, was recognized for his invaluable contributions to wheat research and the development and training of scientists that have increased food production and nutritional security in Mexico, India and numerous other countries in Africa, Asia and Latin America.

“The award recognizes and values many years of wheat breeding at CIMMYT, where I had the opportunity, privilege and satisfaction to have contributed and made impacts through our invaluable partners in India and many other countries,” Singh said. “By continuously providing superior varieties, we increased wheat production and incomes of millions of smallholder farming families.”

Singh’s nomination cited his contribution to the development, release and cultivation by national partners worldwide of over 550 wheat varieties over the past three decades. These national partners include the Indian Council of Agricultural Research (ICAR) and its affiliated institutions in India. These varieties, sown annually on over 40 million hectares by as many farmers, add over $1 billion annually to farmers’ incomes through increased productivity and built-in disease resistance, thus reducing chemical dependence to a negligible level.

“Great teamwork leads to breakthroughs — and is the only way to achieve a common goal. Dr. Ravi Singh’s work alleviating hunger is a great service to mankind,” said Gyanendra Pratap Singh, director of the ICAR Indian Institute of Wheat and Barley Research (ICAR-IIWBR). “We are proud to have him on our team.”

“This award recognizes Dr. Ravi Singh’s important contribution to CIMMYT wheat breeding, delivering major impacts to wheat production and smallholder livelihoods in India, and around the world,” said Alison Bentley, director of CIMMYT’s Global Wheat Program.

Over his career, Singh has nourished and further expanded an already strong partnership between CIMMYT, ICAR and various agricultural universities in India by developing and sharing each year new, diverse wheat varieties possessing increased grain and straw yields, resistance to diseases such as rusts, spot blotch and blast, climate resilience, and processing and nutritional quality.

Over the past decade, Singh’s team developed about half of the wheat varieties released in India through the ICAR network. These include the country’s first high-yielding biofortified varieties, WB-2 and PBW1-Zn, released in 2017 to benefit India’s zinc-deficient population.

Millions of farmers in India continue to grow CIMMYT wheat varieties or their derivatives developed by Indian institutions, to ensure safe and abundant harvests and better nutrition.

Ravi Singh’s numerous recognitions include membership as a Fellow of the American Association for the Advancement of Science (AAAS), the American Phytopathological Society (APS), the Crop Science Society of America (CSSA), the American Society of Agronomy (ASA) and India’s National Academy of Agricultural Science (NAAS). His awards include the Outstanding CGIAR Scientist Award, the CSSA Crop Science Research Award, the University of Minnesota E.C. Stakman Award, and the China State Council’s Friendship Award, among others. He has been included among the top 1% of highly cited researchers according to Clarivate Analytics-Web of Science every year since 2017. Singh also serves as Adjunct Professor at Cornell University and Kansas State University.

The International Maize and Wheat Improvement Center (CIMMYT) sadly notes the passing of Byrd C. Curtis, former Director of the Global Wheat Program, on January 7. He was 95 years old and lived in Fort Collins, Colorado, USA, with his wife Eloise Curtis.

From his studies at Oklahoma State University to retiring after a fruitful international career with Colorado State University, Cargill Inc. and CIMMYT, he never got weary of sharing his passion for breeding better, tastier and sturdier wheat to improve peoples’ livelihoods.

He was an innovator at heart and his legacy will live on through Colorado State University’s wheat breeding program and the many wheat varieties he developed. Not only did he start Colorado State University’s wheat breeding program in 1963, but he also ensured that the varieties that were bred by his team reflected the needs of humanity for decades to come, such as the hard, red winter wheat variety named after himself.

Curtis worked at CIMMYT from 1982 and 1988 as Director of the Global Wheat Program. Together with his team, he worked to position CIMMYT as the leading international research-for-development and breeding organization for wheat for years to come.

“Byrd was very keen to build oral communication skills of scientists, which has been very helpful to me,” said Ravi Singh, Head of Global Wheat Improvement at CIMMYT. “He also initiated the Turkey-CIMMYT-ICARDA International Winter Wheat Improvement Partnership’s (IWWIP) winter wheat breeding program and even worked there in Turkey in his final year with CIMMYT to ensure it would take off well.”

Byrd was instrumental and showed tremendous foresight. IWWIP’s establishment in Turkey became first major breeding program within CGIAR that was hosted by a national program. He strongly supported the creation of the Wide Crossing Program. The synthetic wheat varieties developed in this program have had global impact on wheat improvement.

Aside from his remarkable technical legacy, Byrd had a knack for choosing the right people for the job. In the six years as Director of the Global Wheat Program, he hired scientists who held major roles in global wheat improvement: Ravi Singh, Distinguished Scientist and Head of Global Wheat Improvement; Wolfgang Pfeiffer, former leader of spring bread wheat, durum wheat, and triticale crop improvement; and Hans Braun, Director of the Global Wheat Program from 2004 to 2020.

“Byrd not only initiated the winter wheat program,” said former Global Wheat Program Director Hans Braun, who was hired by Byrd in 1983. “He was also director when the tropical wheat program was implemented in Thailand.” This program’s work increased yields up to 1.5 tons per hectare but ultimately did not convince Thai farmers. Nevertheless, Braun said, “One of the oddest experiences I’ve had was to see our winter wheat material from Turkey grown in the Thai jungle!”

After retiring from his professional life in 1991, Curtis and his wife Eloise moved back to Fort Collins, where his career started in the 1960s and where he will be remembered by his townspeople — and fellow athletes and gym-goers — for his determination and active lifestyle.

The CIMMYT community sends its deepest sympathies and wishes for peace to the Curtis family.

Wheat constitutes 20% of all calories and protein consumed, making it a cornerstone of the human diet, according to the United Nations. However, hotter and drier weather, driven by a changing climate, threatens the global wheat supply. To address this threat, the Foundation for Food and Agriculture Research (FFAR) awarded a $5 million grant to the International Maize and Wheat Improvement Center (CIMMYT) to develop climate-resilient wheat. CIMMYT leads global research programs on maize and wheat, sustainable cropping systems and policies to improve farmers’ livelihoods. These activities have driven major gains in wheat variety improvement across the globe for decades; in the US alone, for example, over 50% of the wheat acreage is sown with CIMMYT-related varieties.

Wheat is among the most widely grown cereal crops in the world and the third-largest crop grown in the US by acre. Nearly all US wheat crops are improved and supported by public agriculture research. As most wheat in the US is dependent on rainfall and has no access to irrigation, this research is critical for helping the plants — and producers — weather climatic changes including extreme heat and drought. Additionally, the demand for wheat is expected to rise in the coming years — as much as 60% by 2050. Without public research, wheat production could decrease by nearly 30% over the same period due to extreme climate conditions.

“FFAR leverages public agriculture research funding through public-private partnerships to pioneer actionable research. With temperatures on the rise and water becoming scarcer, we are committed to supporting wheat farmers and providing new wheat varieties designed with future environmental challenges in mind,” said FFAR’s Executive Director Sally Rockey.

Using the FFAR grant, CIMMYT researchers are pioneering wheat breeding technologies to produce heat-tolerant, drought-resistant and climate-resilient wheat.

CIMMYT researchers and collaborators are applying cutting-edge approaches in genomics, remote sensing and big data analysis to develop new breeding technologies. A key intervention will explore the vast and underutilized reserve of wheat genetic resources to fortify the crop against current and future climate-related stresses.

“This project will help bridge a longstanding gap between state-of-the-art technological findings and crop improvement to deliver climate resilient wheat to farmers as quickly as possible,” said Matthew Reynolds, head of Wheat Physiology at CIMMYT and principal investigator of the project.

Breakthroughs from the FFAR funded project will achieve impact for growers via the International Wheat Improvement Network (IWIN) that supplies new wheat lines to public and private breeding programs worldwide, and has boosted productivity and livelihoods for wheat farmers for over half a century, especially in the Global South.

The research and breeding supported by FFAR will be conducted under the Heat and Drought Wheat Improvement Consortium (HeDWIC), a project led by CIMMYT in partnership with experts across the globe, designed to ensure wheat’s long-term climate resilience. Under the umbrella of the Wheat Initiative’s AHEAD unit, the most relevant advances in academia will be channeled to HeDWIC to help further boost impacts.

“‘Heat,’ ‘drought’ and ‘wheat’ are three of the most important words for billions of people,” said CIMMYT Interim Deputy Director for Research Kevin Pixley. “This partnership between CIMMYT and FFAR will help ensure that the best agricultural science is applied to sustainably raise production of one of the world’s most important staple crops, despite unprecedented challenges.”

CIMMYT Director General Martin Kropff said, “This project represents not only a breakthrough to develop wheat for the future, but also an emerging partnership between CIMMYT and FFAR. I look forward to a productive collaboration that will move us all closer to our mission of maize and wheat science for improved livelihoods.”

FFAR’s investment was matched by co-investments from the CGIAR Research Program on Wheat (WHEAT) and Accelerating Genetic Gains for Maize and Wheat (AGG), a project which is jointly funded by  the Bill & Melinda Gates Foundation and the UK Foreign, Commonwealth, and Development Office (FCDO).

New research by an international team of scientists, including scientists from the International Maize and Wheat Improvement Center (CIMMYT) and the Indian Council of Agricultural Research (ICAR), shows that adopting a portfolio of conservation agriculture and crop diversification practices is more profitable and better for the environment than conventional agriculture.

Reported last month in Nature Scientific Reports, the results of the study should encourage farmers and policymakers in South Asia to adopt more sustainable crop management solutions such as diversifying crop rotations, direct-seeding rice, zero tillage and crop residue retention.

Rice-wheat has for a long time been the dominant cropping system in the western Indo-Gangetic plains in India. However, issues such as water depletion, soil degradation and environmental quality as well as profitability have plagued farmers, scientists and decision makers for decades. To tackle these issues, researchers and policymakers have been exploring alternative solutions such as diversifying rice with alternative crops like maize.

“Climate change and natural resource degradation are serious threats to smallholder farmers in South Asia that require evidence-based sustainable solutions. ICAR have been working closely with CIMMYT and partners to tackle these threats,” said SK Chaudhari, deputy director general of the Natural Resource Management at ICAR.

In the study, CIMMYT scientists partnered with the ICAR-Central Soil Salinity Research Institute, International Rice Research Institute (IRRI), Borlaug Institute for South Asia (BISA), Swami Keshwan Rajasthan Agriculture University and Cornell University to evaluate seven cropping system management scenarios.

The researchers measured a business-as-usual approach, and six alternative conservation agriculture and crop diversification approaches, across a variety of indicators including profitability, water use and global warming potential.

They found that conservation agriculture-based approaches outperformed conventional farming approaches on a variety of indicators. For example, conservation agriculture-based rice management was found to increase profitability by 12%, while decreasing water use by 19% and global warming potential by 28%. Substituting rice with conservation agriculture-based maize led to improvements in profitability of 16% and dramatic reductions in water use and global warming potential of 84% and 95%. Adding the fast-growing legume mung bean to maize-wheat rotations also increased productivity by 11%, profitability by 25%, and significantly decreased water use by 64% and global warming potential by 106%.

However, CIMMYT Principal Scientist and study co-author M.L. Jat cautioned against the allure of chasing one silver bullet, advising policymakers in South Asia to take a holistic, systems perspective to crop management.

“We know that there are issues relating to water and sustainability, but at the same time we also know that diversifying rice — which is a more stable crop — with other crops is not easy as long as you look at it in isolation,” he explained. “Diversifying crops requires a portfolio of practices, which brings together sustainability, viability and profits.”

With South Asia known as a global “hotspot” for climate vulnerability, and the region’s population expected to rise to 2.4 billion by 2050, food producers are under pressure to produce more while minimizing greenhouse gas emissions and damage to the environment and other natural resources.

“Tackling these challenges requires strong collaborative efforts from researchers, policymakers, development partners and farmers,” said Andrew McDonald, a systems agronomist at Cornell University and co-author of the study. “This study shows this collaboration in action and brings us closer to achieving resilient, nutritious and sustainable food systems.”

“The results of this study show that one-size doesn’t fit all when it comes to sustainable crop management,” said PC Sharma, director of India’s ICAR-Central Soil Salinity Research Institute (ICAR-CSSRI). “Farmers, researchers and policymakers can adopt alternative crop rotations such as maize-wheat or maize-wheat-mung bean, but they can also improve existing rice-wheat rotations using conservation agriculture methods.”

The past, present and future of agricultural research

On November 13, 2020, researchers from the International Maize and Wheat Improvement Center (CIMMYT) and the Bangladesh Wheat and Maize Research Institute (BWMRI) held a virtual meeting to update Bangladesh’s Minister for Agriculture Md Abdur Razzaque on their organizations’ ongoing research activities regarding the development of sustainable, cereal-based farming systems.

The purpose of this event was to inform influential stakeholders of the implications of the impending transition to One CGIAR for collaborative research activities in Bangladesh and how CIMMYT will continue its support to the its partners in the country, including the government and other CGIAR centers. The event was chaired by CIMMYT’s Director General Martin Kropff, who called-in from CIMMYT’s headquarters in Mexico, and Razzaque, who attended the event as a special guest. Around 21 participants from various government offices including the Department of Agricultural Extension (DAE) and the Bangladesh Agricultural Research Council (BARC) were in attendance.

Speaking at the event, Razzaque thanked CIMMYT for its support in increasing maize and wheat production in Bangladesh — as the main source of germplasm for these two crops — which has been crucial for assuring food and income security and helping the country reach towards the Sustainable Development Goals. He expressed his gratitude for CIMMYT’s help in mitigating the threats posed by pests and diseases, and supporting climate information services which have enabled farmers to avoid crop losses in mung bean, and he requested that CIMMYT to intensify its research on cropping systems, heat- and disease-tolerant wheat varieties, and the introduction of technologies and farming practices to sustainably increase production and reduce wheat imports.

Timothy J. Krupnik, CIMMYT’s country representative for Bangladesh, guided participants through the history of CIMMYT’s engagement in Bangladesh from the 1960s to the present and outlined the organization’s plan for future collaboration with the government. In addition developing wheat blast-resistant varieties, exchanging germplasm and seed multiplication programs for disease-resistant varieties, Krupnik described collaborative efforts to fight back against fall armyworm, research in systems agronomy to boost crop intensity and the use of advanced simulation models and remote sensing to assist in increasing production while reducing farm drudgery, expensive inputs, water and fuel use, and mitigating greenhouse gas emissions.

He also highlighted efforts to create a skilled work force, pointing to CIMMYT’s collaboration with the Bangladesh Agricultural Research Institute (BARI) on appropriate agricultural mechanization and USAID-supported work with over 50 machinery manufacturers across the country.

“This historical legacy, alongside world-class scientists and committed staff, germplasm collection, global impact in farmer’s fields, next generation research and global network of partners have made CIMMYT unique,” explained Kropff during his closing remarks, which focused on the organization’s research and collaboration on climate-smart and conservation agriculture, high-yielding, stress- and disease-tolerant maize and wheat variety development, value chain enhancement, market development, precision agronomy and farm mechanization in Bangladesh.

He expressed his gratitude towards the Government of Bangladesh for supporting CIMMYT as an international public organization in the country, thus enabling it to continue delivering impact, and for recognizing the benefits of the transition to a more integrated network of international research centers through One CGIAR, under which CIMMYT and other centers will strengthen their support to the government to help Bangladesh achieve zero hunger.
