Perth, Australia – September 24, 2024 – Esteemed Professor Matthew Reynolds, Head of Wheat Physiology at CIMMYT, will deliver a pivotal plenary at the International Wheat Congress, centering on enhancing abiotic stress tolerance in wheat through the integration of complex traits by combining cutting-edge artificial intelligence with genetic diversity. This significant session promises to contribute valuable insights towards addressing the pressing global challenge of food security.
Pioneering Research to Future-Proof Wheat
Crop yield depends on a myriad of traits that interact across various dimensions such as growth stage, plant architecture, and growing environment. Until now, the complexity of these interactions has impeded precision breeding for traits like abiotic stress tolerance, input use efficiency, and yield potential. However, recent advancements in AI, remote sensing, and gene sequencing are making more deterministic breeding feasible.
In his presentation, Professor Reynolds will introduce a series of wiring diagrams representing trait interactions over time for wheat. These diagrams, based on empirical data and crop models, will serve as a framework for AI-assisted simulations to explore different breeding strategies. This innovative approach enables the genetic control of complex traits, allowing for more resilient wheat varieties that can withstand environmental stresses.
Collaborative Efforts Driving Innovation
This initiative is a collaboration between CIMMYT, the University of Florida, University of Queensland, and Wageningen University. The goal is to leverage advanced technologies to combine complex genetic traits in wheat, improving its tolerance to drought, heat, and poor soil conditions. This research holds significant promise for farmers worldwide, ensuring stable yields even under challenging growing conditions.
Impact and Benefits
Global Food Security: By developing high-yielding, climate-resilient wheat varieties, this research contributes to global food security, particularly benefiting farmers in South Asia and Africa.
Environmental Sustainability: Innovative research in Biological Nitrification Inhibition (BNI) addresses nitrogen pollution and enhances nitrogen use efficiency in wheat, contributing to environmental sustainability.
Disease Resistance: Advanced breeding techniques are being employed to develop wheat varieties resistant to devastating diseases like wheat rust, protecting yields and ensuring food security.
“By combining cutting-edge AI and genetic diversity, we are future-proofing wheat to thrive in challenging environments,” said Professor Matthew Reynolds.
The session will take place during Plenary Session 4 on Tuesday, September 24, 2024, from 8:30 am to 8:50 am at the Perth Convention and Exhibition Centre.
About CIMMYT
CIMMYT is a cutting-edge, non-profit, international organization dedicated to solving tomorrow’s problems today. By fostering improved production systems for maize, wheat, and other cereals through applied agricultural science, CIMMYT enhances the livelihoods and resilience of millions of resource-poor farmers while working towards a productive, inclusive, and resilient agrifood system within planetary boundaries.
A new study by CIMMYT, published in Global Change Biology, reveals that ancient wild relatives of wheat, which have adapted to extreme environmental conditions for millions of years, could be key to securing our future food supply. These wild varieties offer valuable genetic traits that can help modern wheat resist diseases, build climate resilience, and reduce agricultural emissions, making them essential for adapting to increasingly challenging growing conditions.
CIMMYT, Mexico, August 27, 2024 — Crop wild relatives that have survived changing climates for millions of years may provide the solution to adapting wheat, humanity’s most widely grown crop, to climate change. Two new studies led by the International Maize and Wheat Improvement Center (CIMMYT) reveal how tapping into this ancient genetic diversity can revolutionize wheat breeding and safeguard global food security.
As the weather becomes more erratic and extreme, wheat — providing 20% of all calories and protein globally and serving as the primary staple food for 1.5 billion people in the Global South — faces unprecedented threats. These include heat waves, delayed rains, flooding, and new pests and diseases.
“We’re at a critical juncture,” says Dr. Matthew Reynolds, co-author of both studies. “Our current breeding strategies have served us well, but they must now address more complex challenges posed by climate change.”
The research points to a vast, largely untapped reservoir of nearly 800,000 wheat seed samples stored in 155 genebanks worldwide. These include wild relatives and ancient, farmer-developed varieties that have withstood diverse environmental stresses over millennia. Although only a fraction of this genetic diversity has been utilized in modern crop breeding, it has already delivered significant benefits.

Proven impacts of wild wheat genes
One of the studies, a review published today in Global Change Biology (GCB)*, documents the immense impact of wild relatives’ traits, including on environmental sustainability. It finds that the cultivation of disease-resistant wheat varieties has avoided the use of an estimated 1 billion liters of fungicide just since 2000.
“Without transferring disease-resistant genes from wild relatives to wheat, fungicide use would have easily doubled, harming both human and environmental health,” says Dr. Susanne Dreisigacker, Molecular Breeder at CIMMYT and co-author of the review.
Sharing of new wheat breeding lines through the CIMMYT-led International Wheat Improvement Network, comprising hundreds of partners and testing sites around the world, increases productivity worth USD 11 billion of extra grain every year. The extra productivity has saved millions of hectares of forests and other natural ecosystems from cultivation.
The review highlights other key breakthroughs using wheat wild relatives, including:
Some experimental wheat lines incorporating wild traits show up to 20% more growth under heat and drought conditions compared to current varieties.
Genes from a wheat wild relative have generated the first crop ever bred to interact with soil microbes, reducing the production of nitrous oxide, a potent greenhouse gas, and enabling the plants to use nitrogen more efficiently.
New, high-yielding cultivars in Afghanistan, Egypt and Pakistan were developed using wild genes and have been released as they are more robust to the warming climate.
“Breeding the first beneficial interaction with the soil microbiome — in this case biological nitrification inhibition, or BNI-wheat — is a landmark achievement by CIMMYT and JIRCAS, opening up a whole new spectrum of opportunities to boost cropping systems’ resilience and reduce environmental footprints,” says Victor Kommerell, co-author of the GCB review, and Director of CropSustaiN, a new research initiative to determine the global climate mitigation and food security potential of BNI wheat.
The second study in Nature Climate Change* showcases the urgent need to scale-up exploration and use of genetic diversity for improved climate resilience. Among the traits needed are deeper, more extensive root systems for better water and nutrient access; photosynthesis that performs well across a wider temperature range; better heat tolerance in reproductive processes; and improved survival during delayed rains or temporary flooding.
“Tapping into the complex climate-resilient traits so urgently needed today requires both access to greater genetic diversity and a paradigm shift in breeding approaches,” explains co-author of the GCB review, Dr. Julie King of Nottingham University.
Modern crop breeding has focused on a relatively narrow pool of ‘star athletes’: elite crop varieties that are already high performers and that have known, predictable genetics. In contrast, the genetic diversity of wild wheat relatives offers complex climate-resilient traits — but their use has been more time-consuming, costly and riskier than traditional breeding approaches with elite varieties. Now, new technologies have changed that equation.
Making the impossible possible
“We have the tools to quickly explore genetic diversity that was previously inaccessible to breeders,” explains Dr. Benjamin Kilian, co-author of the review and coordinator of the Crop Trust’s Biodiversity for Opportunities, Livelihoods and Development (BOLD) project that supports conservation and use of crop diversity globally.
Among these tools are next-generation gene sequencing, big-data analytics, and remote sensing technologies, including satellite imagery. The latter allows researchers to routinely monitor traits like plant growth rate or disease resistance at unlimited numbers of sites globally.
However, realizing the full potential of these genetic resources will require global cooperation. “The most significant impacts will come through widespread sharing of genetic resources and technologies,” says Dr. Kilian.
New technologies allow crop researchers to precisely identify and transfer beneficial traits from wild relatives, making what has been seen as a risky, time-consuming process into a targeted, efficient strategy for climate-proofing crops. “Satellite technology turns the planet into a laboratory,” says Dr. Reynolds, “Combined with artificial intelligence to super-charge crop-breeding simulations, we can identify whole new solutions for climate resilience.”
This research, which also applies to any crop with surviving wild relatives, promises to enhance global food security and make cropping systems more environmentally sustainable. Developing more resilient and efficient wheat varieties will help feed a global population while reducing agriculture’s environmental footprint.

Wheat breeding strategies for increased climate resilience
With the challenges of climate change already affecting plant breeding, especially warmer days and warmer nights, the time to future proof the world’s food supply is now. In order to make the best-informed changes, scientists at CIMMYT ran simulations mimicking five scenarios that might play out over the next 70+ years.
The researchers used 3,652 breeding line records from six global nurseries administered by the International Wheat Improvement Network, which is coordinated by CIMMYT, and involves hundreds of partners and testing sites worldwide. Researchers ran the data through five different climate change scenarios, ranging from stable to severe.
Along with colleagues from Henan Agricultural University, Zhengzhou, China, ICARDA, and the Chinese Academy of Agricultural Sciences, CIMMYT scientists published their research in Nature Climate Change.
The results showed that less than one-third of wheat varieties adapted well to the warming the planet has already seen in the last 10 years. As temperatures increased in the simulation, researchers found a clear connection between rising temperatures and lower stability for a variety. As the global wheat-growing area becomes warmer and experiences more frequent heatwaves, breeding programs have to look beyond just yield optimization.
“Stability is key for breeding programs and farmers,” said co-lead author Matthew Reynolds, CIMMYT distinguished scientist and head of wheat physiology. “Knowing that a specific variety works well in a specific environment and produces an expected amount of yield allows farmers better plan their crop futures.”
“We performed the analysis from different perspectives, so that climate effects and appropriate adjustment suggestions for current breeding models can be considered from climate change, gene selection and/or gene–environment interaction perspectives,” said co-lead author Wei Xiong, CIMMYT Senior Scientist and Agricultural System Modeler.
The paradox of breeding elite lines
Local and regional breeding programs, as well as targeted breeding by CIMMYT, contribute to gene pools that overlap for many key agronomic traits, which limit genetic diversity.
“It is an unintended consequence,” said Reynolds. “As conventional breeding focuses on crossing the best and elite material, such focus can actually reduce genetic diversity.”
This ‘paradox’ shows the need to increase genetic variability and environmental diversification in breeding programs that are developing higher-yielding climate-resilient cultivars. Breeding programs also need to target traits associated with improved adaptation to increased temperatures and tolerance to heatwaves, which requires multidisciplinary integration.
Looking to the past for answers
Over the past 10,000 years, the climate has been unusually stable, meaning modern, domesticated bread wheat has not been exposed to wide swings in temperature that are forecast for the next 100 years. Wild wheat relatives, like Triticeae, have had millions of years of experience in weathering changing climates.
CIMMYT has a pre-breeding program that examines wild wheat races and more exotic sources for climate resilience traits. When such traits are identified genetically, new breeding techniques such as gene editing can be employed and breeding models refined.
To activate these new techniques, several barriers need to be overcome, including more sharing of germplasm between countries and breeding teams, the use of faster breeding cycles where appropriate and improved understanding of genes that improve heat tolerance without a yield penalty.
With reduced climate resilience and slow cultivar development, the need to increase genetic variability for climate adaptation is urgent, particularly in developing countries, where warming rate is unprecedented, and breeding cycles tend to be longer than in developed countries.
“Faced with more climate variability, breeders need to revisit their breeding strategies to integrate genetic diversity that confers climate resilience without penalties to productivity,” said Reynolds.
In a discussion on the future of crop breeding at the Cereals seminar, experienced wheat breeder Bill Angus highlighted CIMMYT as a leading example of effective global crop breeding, particularly for regions with limited agricultural inputs. He emphasized that while the UK has a competitive wheat breeding environment, it could learn from CIMMYT’s approach, which successfully develops wheat varieties suited for the developing world, where farmers often lack the luxury of chemical inputs. Angus advocated for the UK to adopt a more impactful and globally engaged breeding strategy, drawing inspiration from CIMMYT’s successes.

A study by the Technical University of Munich (TUM) warns that the wheat blast fungus Magnaporthe oryzae threatens up to 75% of Africa’s wheat cultivation. The disease, spread by windborne spores and exacerbated by climate change, worsens food insecurity. While Zimbabwe remains unaffected, preventive measures are in place. The Zambia Agriculture Research Institute (ZARI), with CIMMYT’s collaboration, is building regional capacity to combat the disease. The study emphasizes the need for resistant wheat varieties and enhanced global and regional cooperation to protect wheat production and ensure food security.
Ethiopia is the largest wheat producer in Africa, accounting for around 65% of the total wheat production in sub-Saharan Africa. Despite the old tradition of rainfed wheat cultivation in the highlands, irrigated production in the dry, hot lowlands is a recent practice in the country.
In the irrigated lowlands of Afar and Oromia, situated along the Awash River Basin, CIMMYT and the Ethiopian Institute of Agricultural Research (EIAR) have been supporting small scale farming households to improve yields since 2021. The Adaptation, Demonstration and Piloting of Wheat Technologies for Irrigated Lowlands of Ethiopia (ADAPT-Wheat) project supports research centers to identify new technologies suitable for target planting areas through adaptation and development, which are then released to farmers. Funded by Germany’s Federal Ministry for Economic Development (BMZ) and Deutsche Gesellschaft fuer Internationale Zusammenarbeit (GIZ) GMBH, EIAR leads on implementation while CIMMYT provides technical support and coordination.

So far, several bread and durum wheat varieties and agronomic practices have been recommended for target areas through adaptation and demonstration. The seeds of adapted varieties have been multiplied and distributed to small scale farmers in a cluster approach on seed loan basis.
Cross-continent collaboration
The Werer Agricultural Research Center (WRC) run by EIAR has released two wheat varieties: one bread wheat line (EBW192905) and one durum wheat line (423613), both suitable for agroecology between 300-1700 meters above sea level.
Both varieties were selected from the CIMMYT wheat breeding program at its headquarters in Mexico. The new bread wheat variety exceeded the standard checks by 17% (Gaámabo and Kingbird) and 28% (Mangudo and Werer).
The lines were trialed through multi-location testing in Afar and Oromia, with both lines displaying tolerance to biotic and abiotic stresses. Accelerated seed multiplication of these varieties is in progress using main and off seasons.

“These new varieties will diversify the number of adapted wheat varieties in the lowlands and increase yields under irrigation” said Geremew Awas, a CIMMYT research officer working for the ADAPT project in Ethiopia. Hailu Mengistu, EIAR wheat breeder at WRC, also indicated the need for fast seed delivery of climate resilient wheat varieties on farmers’ hands to realize genetic gain and increase income and food security of the households.
These new varieties will be provided with a local name by breeders to make it easy for farmers and other growers to identify them and will be introduced to farmers through demonstrations and field days. Eligible seed growers who are interested in producing and marketing the basic and certified seeds of these varieties can access early generation seeds from the WRC.
The irrigated lowlands of Afar and Oromia in Ethiopia are vital areas for the cultivation of wheat and increasing their productivity is crucial to attaining food security in the light of extended drought and other climate shocks.
Adaptation, Demonstration, and Piloting of Wheat Technologies for Irrigated Lowlands of Ethiopia (ADAPT-Wheat) is a three-year project funded by Germany’s Federal Ministry for Economic Cooperation and Development with the objective of identifying, verifying, and adopting wheat technologies that increase wheat production and productivity in Afar and Oromia.
As part of ADAPT-Wheat’s capacity building mission, four Ethiopian wheat researchers from different disciplines visited the Indian Central Soil Salinity Research Institute (CSSRI), the Indian Institute of Wheat and Barely Research (IIWBR), Land force (Dasmesh Mechanical Works), the Borlaug Institute for South Asia (BISA), and National Agro Industries from 13 -22 March 2024.
At CSSRI, the researchers learned how to reclaim salt-affected soils through the use of salt tolerant crops, improve management of water usage, and employ cover crops in salt-affected soils to reduce soil temperature and evapotranspiration. They also visited a sodic and saline microplot facility used to screen genotypes under the desired salinity and sodicity stresses. The researchers witnessed ongoing activities such as agrochemical/ biological/hydraulic technologies to reclaim salt-affected soils, the use of poor-quality irrigation water for crop production and the adoption of ameliorative technologies for salinity management.
The Ethiopian researchers also attended an international conference organized by the Indian Society of Soil Salinity and Water Quality, “Rejuvenating salt affected soil ecologies for land degradation neutrality under changing climate.”

They learned about breeding methods, and advances in yield enhancement, disease resistance, sustainable agricultural practices, innovative farming methods, genetic stocks developed for grain protein, iron, and zinc enhanced wheat varieties, phytic acid levels, gluten strength, and grain texture.
At Dasmesh Mechanical Works, they learned the operation and maintenance of equipment ADAPT-Wheat has purchased from Dasmesh, including machines for plowing, land leveling, planting, and threshing.
The visit to BISA included an introduction to Conservation Agriculture methods, such as fertilizer use efficiency and crop residue management, which will ultimately help improve productivity back in Ethiopia. They also viewed an ongoing experiment on Precision–Conservation Agriculture Based Maize-Wheat Systems.
Finally, the researchers visited the CIMMYT-India office and met with Mahesh Kumar Gathala, systems agronomist and lead scientist.
“We are proud to host our Ethiopian colleagues. Collaborating with them allowed us to learn as much from them as they hopefully learned from us during their visit,” said Gathala.

For Daniel Muleta (irrigated wheat project coordinator), Shimelis Alemayehu (agronomist), Hailu Mengistu (wheat breeder) and Lema Mamo (soil scientist) all from Ethiopian Institute of Agricultural Research (EIAR), the visit to India was beyond their imagination and gave them the opportunity to participate in salinity workshop, visited different institutions and gained experience. Shimelis said “even though the workshop was for experience sharing the travel made was beyond that”.
The team acknowledged CIMMYT-Ethiopia and CIMMYT India offices and EIAR management.
As the global population approaches the 10 billion mark, the reliance on fertilisers to boost agricultural production has become an essential, yet environmentally challenging, practice. A Century-long dependence on these additives has allowed food production to keep pace with the growth in human population. However, the use of fertilisers across various farming systems is now causing severe ecological stress. The leaching of nitrogen into natural ecosystems, coupled with the release of greenhouse gases, is pushing the Earth’s environmental limits to a critical threshold.
To address this, an ambitious new research initiative aims to shrink the nitrogen footprint of agriculture by developing a breakthrough technology based on nature’s own solutions: a natural process called biological nitrification inhibition (BNI). The Novo Nordisk Foundation has awarded CIMMYT a grant of up to USD 21.1 million to lead an innovation research initiative called CropSustaiN that is designed to reduce the nitrogen footprint of wheat cultivation.
“Success in this initiative could lead to a major shift in agricultural practices globally, benefiting both the planet and farmers’ livelihoods. In addition to using less fertiliser, cost for the farmer will be minimal because all the components are already in the seed. This initiative could, potentially, be extended from wheat cultivation to include other staple crops like maize and rice,” says Claus Felby, Senior Vice President, Biotech, Novo Nordisk Foundation.
“BNI could be a part of how we revolutionise nitrogen management in agriculture. It represents a genetic mitigation strategy that not only complement existing methods but also has the potential to decrease the need for synthetic fertilisers substantially. The mitigation potential of better nitrogen fertiliser management could be as impactful for the Global South as the Green Revolution,” explains Bram Govaerts, Director General, CIMMYT.
Revolutionary mitigation approach
Rooted in a seed-based genetic strategy, BNI leverages a plant’s innate ability to suppress soil nitrification through the release of natural compounds. This approach potentially promises to curb the use and leaching of synthetic nitrogen fertilisers—a significant contributor to greenhouse gas emissions and water pollution—without compromising wheat yield or soil vitality. The BNI-method contrasts with synthetic nitrification inhibitors and could offer a more scalable and cost-effective solution, potentially reducing nitrogen fertiliser usage by 20%, depending on regional farming conditions.
By harnessing the power of genetics in plant seeds, CropSustaiN leverages the natural process of BNI to develop new wheat varieties that require significantly less nitrogen fertiliser. Using conventional breeding, genes from wild crop relatives like wild rye, which have inherently better nitrogen use efficiency, are incorporated. CIMMYT makes such breeding products available to its global network of partners for the international public good.
The agenda for CropSustaiN includes validating BNI efficacy across diverse climates and integrating the technology into mainstream agricultural protocols. While the venture carries success risks, the potential rewards—ranging from widespread BNI adoption to valuable insights into nitrogen management—position it as a pioneering initiative. By ensuring that the seeds developed through this program are accessible to all farmers without exclusive patent rights, the Novo Nordisk Foundation is leading an inclusive approach to agricultural innovation.
CropSustaiN builds on the joint research by the Japan International Research Center for Agricultural Sciences (JIRCAS) and CIMMYT that started in 2015. The initiative has already yielded BNI wheat lines tested over three farming seasons. These innovative crops are now poised for further development and for scaling worldwide, indicating a potential paradigm shift in agricultural practices.
The Novo Nordisk Foundation has already laid the groundwork for CropSustaiN by funding related BNI research at CIMMYT, the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), Aarhus University, the University of Aberdeen, and the University of Copenhagen -thus fostering an ecosystem for research innovation.
