The largest real-world test of grains that grow year after year without replanting is showing promise for saving money, helping the environment, and reducing labor in China.
Initial trials with perennial rice as part of the Sustainable Agrifood Systems (SAS) program by the International Maize and Wheat Improvement Center (CIMMYT) suggest the crop could be a game changer for agriculture and food security.
The next phase of the research will determine whether farmers wish to adopt Perennial Rice 23 (PR23), which has been developed by breeding an Asian variety of rice with a wild, perennial relative from Nigeria.
Mustafa Alisarli, Bolu Abant Izzet Baysal University rector, is awarded for hosting this symposium by the representative of the Turkish Ministry of Agriculture and Forestry, General Directorate of Agricultural Research and Policies (GDAR), Dr Suat Kaymak.
The International Maize and Wheat Improvement Center (CIMMYT) coordinated the VIII International Cereal Nematode Symposium between September 26-29, in collaboration with the Turkish Ministry of Agriculture and Forestry, the General Directorate of Agricultural Research and Policies and Bolu Abant Izzet Baysal University.
As many as 828 million people struggle with hunger due to food shortages worldwide, while 345 million are facing acute food insecurity – a crisis underpinning discussions at this symposium in Turkey focused on controlling nematodes and soil-borne pathogens causing reduced wheat yields in semi-arid regions.
A major staple, healthy wheat crops are vital for food security because the grain provides about a fifth of calories and proteins in the human diet worldwide.
Seeking resources to feed a rapidly increasing world population is a key part of tackling global hunger, said Mustafa Alisarli, the rector of Turkey’s Bolu Abant Izzet Baysal University in his address to the 150 delegates attending the VIII International Cereal Nematode Symposium in the country’s province of Bolu.
Suat Kaymak, Head of the Plant Protection Department, on behalf of the director general of the General Directorate of Agricultural Research and Policies (GDAR), delivered an opening speech, emphasizing the urgent need to support the CIMMYT Soil-borne Pathogens (SBP) research. He stated that the SBP plays a crucial role in reducing the negative impact of nematodes and pathogens on wheat yield and ultimately improves food security. Therefore, the GDAR is supporting the SBP program by building a central soil-borne pathogens headquarters and a genebank in Ankara.
Discussions during the five-day conference were focused on strategies to improve resilience to the Cereal Cyst Nematodes (Heterodera spp.) and Root Lesion Nematodes (Pratylenchus spp.), which cause root-health degradation, and reduce moisture uptake needed for proper development of wheat.
Richard Smiley, a professor emeritus at Oregon State University, summarized his research on nematode diseases. He has studied nematodes and pathogenic fungi that invade wheat and barley roots in the Pacific Northwest of the United States for 40 years. “The grain yield gap – actual versus potential yield – in semiarid rainfed agriculture cannot be significantly reduced until water and nutrient uptake constraints caused by nematodes and Fusarium crown rot are overcome,” he said.
Experts also assessed patterns of global distribution, exchanging ideas on ways to boost international collaboration on research to curtail economic losses related to nematode and pathogen infestations.
A special session on soil-borne plant pathogenic fungi drew attention to the broad spectrum of diseases causing root rot, stem rot, crown rot and vascular wilts of wheat.
Soil-borne fungal and nematode parasites co-exist in the same ecological niche in cereal-crop field ecosystems, simultaneously attacking root systems and plant crowns thereby reducing the uptake of nutrients, especially under conditions of soil moisture stress.
Limited genetic and chemical control options exist to curtail the damage and spread of these soil-borne problems which is a challenge exacerbated by both synergistic and antagonistic interactions between nematodes and fungi.
Nematodes, by direct alteration of plant cells and consequent biochemical changes, can predispose wheat to invasion by soil borne pathogens. Some root rotting fungi can increase damage due to nematode parasites.
Integrated managementFor a holistic approach to addressing the challenge, the entire biotic community in the soil must be considered, said Hans Braun, former director of the Global Wheat Program at CIMMYT.
Braun presented efficient cereal breeding as a method for better soil-borne pathogen management. His insights highlighted the complexity of root-health problems across the region, throughout Central Asia, West Asia and North Africa (CWANA).
Richard A. Sikora, Professor emeritus and former Chairman of the Institute of Plant Protection at the University of Bonn, stated that the broad spectrum of nematode and pathogen species causing root-health problems in CWANA requires site-specific approaches for effective crop health management. Sikora added that no single technology will solve the complex root-health problems affecting wheat in the semi-arid regions. To solve all nematode and pathogen problems, all components of integrated management will be needed to improve wheat yields in the climate stressed semi-arid regions of CWANA.
Building on this theme, Timothy Paulitz, research plant pathologist at the United States Department of Agriculture Agricultural Research Service (USDA-ARS), presented on the relationship between soil biodiversity and wheat health and attempts to identify the bacterial and fungal drivers of wheat yield loss. Paulitz, who has researched soil-borne pathogens of wheat for more than 20 years stated that, “We need to understand how the complex soil biotic ecosystem impacts pathogens, nutrient uptake and efficiency and tolerance to abiotic stresses.”
Julie Nicol, former soil-borne pathologist at CIMMYT, who now coordinates the Germplasm Exchange (CAIGE) project between CIMMYT and the International Center for Agricultural Research in the Dry Areas (ICARDA) at the University of Sydney’s Plant Breeding Institute, pointed out the power of collaboration and interdisciplinary expertise in both breeding and plant pathology. The CAIGE project clearly demonstrates how valuable sources of multiple soil-borne pathogen resistance in high-yielding adapted wheat backgrounds have been identified by the CIMMYT Turkey program, she said. Validated by Australian pathologists, related information is stored in a database and is available for use by Australian and international breeding communities.
Economic losses
Root-rotting fungi and cereal nematodes are particularly problematic in rainfed systems where post-anthesis drought stress is common. Other disruptive diseases in the same family include dryland crown and the foot rot complex, which are caused mainly by the pathogens Fusarium culmorum and F. pseudograminearum.
The root lesion nematode Pratylenchus thornei can cause yield losses in wheat from 38 to 85 percent in Australia and from 12 to 37 percent in Mexico. In southern Australia, grain losses caused by Pratylenchus neglectus ranged from 16 to 23 percent and from 56 to 74 percent in some areas.
The cereal cyst nematodes (Heterodera spp.) with serious economic consequences for wheat include Heterodera avenae, H. filipjevi and H. latipons. Yield losses due to H. avenae range from 15 to 20 percent in Pakistan, 40 to 92 percent in Saudi Arabia, and 23 to 50 percent in Australia.
In Turkey, Heterodera filipjevi has caused up to 50 percent crop losses in the Central Anatolia Plateau and Heterodera avenae has caused up to 24 percent crop losses in the Eastern Mediterranean.
The genus Fusarium which includes more than a hundred species, is a globally recognized plant pathogenic fungal complex that causes significant damage to wheat on a global scale.
In wheat, Fusarium spp. cause crown-, foot-, and root- rot as well as head blight. Yield losses from Fusarium crown-rot have been as high as 35 percent in the Pacific Northwest of America and 25 to 58 percent in Australia, adding up losses annually of $13 million and $400 million respectively, due to reduced grain yield and quality. The true extent of damage in CWANA needs to be determined.
Abdelfattah Dababat, CIMMYT’s Turkey representative and leader of the soil-borne pathogens research team said, “There are examples internationally, where plant pathologists, plant breeders and agronomists have worked collaboratively and successfully developed control strategies to limit the impact of soil borne pathogens on wheat.” He mentioned the example of the development and widespread deployment of cereal cyst nematode resistant cereals in Australia that has led to innovative approaches and long-term control of this devastating pathogen.
Dababat, who coordinated the symposium for CIMMYT, explained that, “Through this symposium, scientists had the opportunity to present their research results and to develop collaborations to facilitate the development of on-farm strategies for control of these intractable soil borne pathogens in their countries.”
Paulitz stated further that soil-borne diseases have world-wide impacts even in higher input wheat systems of the United States. “The germplasm provided by CIMMYT and other international collaborators is critical for breeding programs in the Pacific Northwest, as these diseases cannot be managed by chemical or cultural techniques,” he added.

Road ahead
Delegates gained a greater understanding of the scale of distribution of cereal cyst nematodes and soil borne pathogens in wheat production systems throughout West Asia, North Africa, parts of Central Asia, Northern India, and China.
After more than 20 years of study, researchers have recognized the benefits of planting wheat varieties that are more resistant. This means placing major emphasis on host resistance through validation and integration of resistant sources using traditional and molecular methods by incorporating them into wheat germplasm for global wheat production systems, particularly those dependent on rainfed or supplementary irrigation systems.
Sikora stated that more has to be done to improve Integrated Pest Management (IPM), taking into consideration all tools wherever resistant is not available. Crop rotations for example have shown some promise in helping to mitigate the spread and impact of these diseases.
“In order to develop new disease-resistant products featuring resilience to changing environmental stress factors and higher nutritional values, modern biotechnology interventions have also been explored,” Alisarli said.
Brigitte Slaats and Matthias Gaberthueel, who represent Swiss agrichemicals and seeds group Syngenta, introduced TYMIRIUM® technology, a new solution for nematode and crown rot management in cereals. “Syngenta is committed to developing novel seed-applied solutions to effectively control early soil borne diseases and pests,” Slaats said.
It was widely recognized at the event that providing training for scientists from the Global North and South is critical. Turkey, Austria, China, Morocco, and India have all hosted workshops, which were effective in identifying the global status of the problem of cereal nematodes and forming networks and partnerships to continue working on these challenges.

AGG is a collaborative project led by the International Maize and Wheat Improvement Center (CIMMYT) bringing together global partners to advance the development of higher-yielding varieties.
This field day was organized by the Crops Research Institute at Ghana’s Council for Scientific and Industrial Research (CSIR-SARI), the International Institute of Tropical Agriculture (IITA) and the department of agriculture.
During the event, researchers aimed to encourage farmer adoption by familiarizing them with the stress-tolerant hybrids and emphasizing the high and stable grain yields.
To mitigate their amount of greenhouse gas (GHG) emissions, companies and individuals have access to international voluntary carbon offset markets, which are trading systems that financially compensate credit producer participants for offsetting the amount of carbon emitted. An innovative new initiative from the International Maize and Wheat Improvement Center (CIMMYT) and the Indian Council of Agricultural Research Institute (ICAR) is working to establish carbon markets among smallholder farmers in India, with the goal of reducing GHG emissions, encouraging climate smart farming practices through financial incentives.
In India, agriculture is one of the biggest sources of GHG emissions – between 14 and 21 percent of all GHGs are attributable to agricultural activities, which derive from the use of farm machinery, rice cultivation, fertilizer use, and other activities. Emissions from agriculture are increasing drastically due to synthetic fertilizers and enteric fermentation from livestock.
Within CIMMYT’s farmer-centered approach, participants in voluntary carbon markets will improve their own financial viability in two ways – through adopting sustainable practices and through receipt of payments from carbon markets. The approach will also employ regenerative interventions such as direct dry seeding of rice, minimal tillage, crop diversification, use of biofertilizers, and perennial cropping all while contributing to an overall reduction in GHG emissions.
“Working with ICAR to engage smallholder farmers with high-quality carbon offsets allows the farmers to offset their unavoidable emissions,” said Vijesh Krishna, senior CIMMYT scientist. “This program promotes inclusiveness because this newly created income is distributed among participating farmers, thereby improving their income.”
These regenerative agriculture interventions will increase and retain soil’s carbon content, water permeability and retention, resulting in crops’ ability to withstand drought, flooding, and temperature stresses. Only a small percentage of farmers currently implement these methods in India.
CIMMYT and ICAR researchers estimate that widespread adoption of these practices, combined with upgraded technologies, has the potential to return the carbon levels in agricultural soils from an average of 0.5 percent back to 1.5 percent. At present, the agricultural soils of India are poor with respect to soil organic carbon.
Carbon markets for smallholders
About 2,000 small holder farmers of Punjab, Haryana, and parts of Maharashtra, all in India, are enrolled in the project through individual partnership agreements. Once farmers implement regenerative agricultural methods, they will be eligible to receive payments for carbon credits generated for 10 to 20 years, conditional upon continuing to use climate-smart practices.
“We believe these efforts can be expanded to other regions of India, and other countries,” said Sieg Snapp, CIMMYT’s Sustainable Agrifood Systems (SAS) program director. “Helping farmers and reducing GHG emissions at the same time is the way forward in dealing the crisis of climate change.”
Farms are geo-tagged and monitored using remote sensing for regenerative farming practices, and soil carbon content will be measured at the beginning and end of the crop cycle. Those that produce rice and wheat with a lower carbon footprint will be identified, so their produce gets purchase and price preferences from those who want to promote lower carbon agriculture.
Digital agronomy tools and satellite imagery analysis to measure and verify soil carbon offsets and on-farm GHG emission levels are essential for scaling small farmer-centered carbon projects. The veracity, transparency, and traceability of each carbon offset have direct implications for its credibility and actual market value. CIMMYT will contribute towards a Measurement, Reporting, and Verification (MRV) platform to expand climate action country-wide.
So far, CIMMYT and ICAR researchers estimate that the enrolled smallholder famers have sequestered between four and five tons of carbon dioxide. After independent third-party auditors verify the data, farmers will be paid based on the amount of GHG reduction, with the first carbon offset payments expected to be issued in 2023.

The conflict between Russia and Ukraine undoubtedly impacts food security, as these two countries are responsible for more than a quarter of wheat traded globally. Developing countries that rely heavily on wheat imports are most at risk from this supply disruption.
Set against an existing backdrop of food insecurity and increasing poverty, the conflict exacerbates present challenges. The United Nations Food and Agriculture Organization (FAO) predicts that a further 11 to 19 million people will be experiencing chronic hunger by 2023, on top of the existing 193 million people facing food insecurity, and at least 47 countries are expected to fall short of the Zero Hunger target, one of the UN Sustainable Development Goals (SDGs).
In a study at the International Maize and Wheat Improvement Center (CIMMYT), scientists theorized that the domestic price of wheat is determined by the international price. Their hypothesis also supposed that wheat production is constant and that no significant change in wheat consumption habits is expected in the foreseeable future.
Schematic diagram on the relationship between export-import price, producer price, and wheat consumption.
Scientists discovered that a 1 percent decrease in the global wheat trade could increase the producers’ price by 1.1 percent in the countries sampled. Furthermore, a 1 percent increase in the producers’ price could reduce annual per capita wheat consumption by 0.59 percent, daily calorie intake by 0.54 percent and protein intake by 0.64 percent. A 50% reduction in Russian and Ukrainian wheat exports could increase prices by 15 percent, leading to an 8% reduction in wheat consumption and dietary energy intake.
Rising costs of staple foods such as wheat can lead to violence and social unrest, as witnessed in 2007-11. It is therefore vital to ensure that import-dependent, resource-poor countries are supported to address their precarious food security. Steady public funding, investment in research, and enhanced production in wheat-growing nations can play an integral role in achieving a solution. In the long-term, closing the yield gap through research and investment, particularly in Africa, will lead towards self-sufficiency in wheat in Africa, contributing towards overall food security across the continent.
The International Maize and Wheat Improvement Center (CIMMYT) Director General, Bram Govaerts, participated in a panel discussion on applied maize science to sustainably feed the world as part of the International Maize Congress on October 19-20, 2022 in Argentina.
The congress was organized by the governments of Córdoba and of the Central Region provinces of Argentina, together with the Argentine Maize and Sorghum Association (MAIZAR) and the Córdoba Grain Exchange.
Other panelists for the session included representatives from Argentina’s National Agricultural Technology Institute (INTA), the National Scientific and Technical Research Council (CONICET), and the National University of Mar del Plata.
In his presentation, Govaerts highlighted CIMMYT’s scientific efforts to improve the resilience of grain-based systems and produce sufficient, nutritious, and sustainable diets. He also shared CIMMYT’s determination to adopt a collaborative and future-proof approach to research, factoring in climate change to support effective decision-making processes for food producers and to meet demand for innovations and technologies.
The origins of the CGIAR, the world’s largest publicly funded agricultural research consortium for the poor, are closely related to the Green Revolution; a revolution mostly told as the work of one Northern hero with a superior technology that saved the world from starvation. Only recently has the notion that the introduction of that superior technology was one of many investments and innovations that kicked off as the Revolution started to gain ground – and that these investments and innovations came from both the North and South. Scaling of innovation happens in a larger system, often one that feels resistant to whatever we try to scale or, like in the case of the Green Revolution, aligned with what was being scaled and thus led to a tipping point and a completely new way agriculture is produced. The Revolution changed our relation to food, from which there was no going back.
In my ten years at the CGIAR – from 2005 to 2010 at the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) and then from 2017 to now at the International Maize and Wheat Improvement Center (CIMMYT) – major shifts can be observed in how scaling is approached.
First, scaling equals large adoption during the project, stemming from strong confidence that “if we build it, they will come”, or we just show how good our innovation is and others will scale it. From my own experience developing scale-appropriate drip irrigation in the Sahel, North Africa, I can say that approach hardly worked. When I re-joined the CGIAR in 2017, there was much more attention to the context in which the intervention is being scaled – we need to “create an enabling environment” for the innovation, and multiple innovations need to scale alongside “our”, mostly technical, innovation. It was very interesting to see up close how more and more colleagues have started to question whether scaling is “good” in the first place and whether it should be about “our” innovations.
COVID-19 and the major energy transitions that are going on in Europe and some states in the United States of America (USA) seem to have awoken a much stronger systems view, the realization that change takes decades, and that there are winners and losers in that process. I think we did a great job in questioning the “silver bullet” and “transfer of technology” mindset and see the achievement of the UN Sustainable Development Goals (SDGs) as a transition process that requires radically different approaches and addresses multiple leverage points.
Scaling at One CGIAR
The major reform from 15 CGIAR centers to One CGIAR was the perfect opportunity to take scaling seriously as a science and an art. A range of methodologies have been developed, and informal networks of like-minded people have worked together a lot to push for a new paradigm on scaling. It is great that scaling is now well embedded in the One CGIAR strategy for the future. The big One CGIAR Initiatives have all reserved about 5 percent of their budgets to integrate scaling expertise. Also, scaling is very much recognized as a topic that requires a culture and mindset change within the organization to be much more effective.
Not surprisingly, the Call to Action from the Global South and its eight action points resonated a lot with me, especially since the following principles match really well:
It is not about reaching a target as fast as possible but about the whole environment for sustainability – more is not always better. Scaling can help us understand whether project outputs have contributed to something good (Action 1).
We need to reflect better on the viability of some innovations to go to scale – rather than promoting or selling our own solutions, supporting Southern solutions could increase viability (Action 7).
Problem owners should be in charge of scaling – scaling should be a locally owned process where those on the ground negotiate what is good and enough, and we, the research and development organizations, facilitate and support (Action 2).
The way projects are designed and implement set us up for failure. We create fake, highly controlled environments designed to prove that our innovation works – the gap with the reality on the ground could not be larger. The development community, with donors, need to rethink our approach (Action 5).
We need to invest in learning and the science of scaling. Organizations in the Global North need modesty in understanding that our role is not neutral and realize that there is so much we don’t know (Action 8).
Within organizations, scaling is a cultural issue tightly connected to change management. We need to shift mindsets and behaviors to allow better scaling to happen.
That this Call comes from researchers in the Global South is so powerful. It shows us that the current ways of working are not delivering and paints a picture of a better way of doing things, but at the moment, we are in uncertain limbo between the two. The guidance in the Call can help to incite momentum and change. I believe we are coming to a critical mass of people that can tip the scale and that the actions in the Call can become the new normal – so that the stories we tell in the future focus not just on external (Northern) innovations that lead to big change, but on the interplay between what is going in the South and how external “solutions” fit in.

How does CIMMYT’s improved maize get to the farmer?
CIMMYT is happy to announce four new, improved tropical maize hybrids that are now available for uptake by public and private sector partners, especially those interested in marketing or disseminating hybrid maize seed across Latin America and similar agro-ecological zones. Public- and private-sector organizations are hereby invited to apply for licenses to pursue national release and /or scale-up seed production and deliver these maize hybrids to farming communities.
The deadline to submit applications to be considered during the first round of allocations is 25 November 2022. Applications received after that deadline will be considered during subsequent rounds of product allocations.
The newly available CIMMYT maize hybrids, CIM20LAPP1C-9, CIM20LAPP1C-10, CIM20LAPP1A-11 and CIM20LAPP1A-12, were identified through rigorous trialing and a stage-gate advancement process which culminated in the 2020 and 2021 CIMMYT Latin America Stage 4 and Stage 5 Trials. The products were found to meet the stringent performance criteria for CIMMYT’s LA-PP1A and LA-PP1C breeding pipelines. While there is variation between different products coming from the same pipeline, the LA-PP1A and LA-PP1C pipelines are designed around the target product profiles described below:

Food crops and animal feeds produced through biotechnology innovations can now be imported into Kenya after the ban on genetically modified organisms (GMOs) was lifted.
Kenyan scientists and research institutions are now able to develop crop varieties that will benefit farmers and their communities.
In a landmark statement on October 3, the Cabinet said: “In accordance with the recommendation of the Task Force to review matters relating to GMOs and Food Safety, and in fidelity with the guidelines of the National Biosafety Authority (NBA) on all applicable international treaties including the Cartagena Protocol on Biosafety (CPB), Cabinet vacated its earlier decision of 8th November 2012 prohibiting the open cultivation of GMOs and the importation of food crops and animal feeds produced through biotechnology innovations; effectively lifting the ban on GMOs. By dint of the executive action open cultivation and importation of white (GMO) maize is now authorized.”

Experts at the International Maize and Wheat Improvement Center (CIMMYT) are working with partners to drive self-sufficiency in poultry feed and achieve more sustainable maize systems in Nepal thanks to the Nepal Seed and Fertilizer (NSAF) project.
About 3,000 metric tons (t) of poultry feed is used in Nepal every day, with maize making up about half of feed ingredients. The Feed Association of Nepal estimates that more than 80% of maize for animal feed requirements are met through imports, which costs around $100 million a year. Maize imports are estimated to exceed $130 million in 2022.
Through the NSAF project — a project which facilitates sustainable increases in Nepal’s national crop productivity, income and household-level food and nutrition security across 20 districts — CIMMYT scientists have been supporting public private partnerships to increase commercial maize production and strengthen the “seed to feed” chain in the country.
In the Terai region, huge swaths of land lie fallow in the spring season. Experts estimate that enough maize grain could be produced on this land to substitute about 40% of maize imports to the country. Increasing spring maize production in these fallow lands has been one of the goals of the NSAF team, as well as improving coordination between public and private sectors. To do this, the team have designed a multi-stakeholder engagement initiative to strengthen the seed to feed chain.
In December 2020, CIMMYT experts began the initiative to scale up the use of new maize hybrid varieties and improved agronomic practices. In the spring of 2022, CIMMYT researchers partnered with public and private organizations in Banke, Bardiya and Kailali to help commercialize hybrid maize production and strengthen maize value chain coordination in the region. Partners included integrated agriculture and livestock development offices in Bardiya, agriculture knowledge centers in Banke and Kailali, local governments, farmer cooperatives, seed companies, agro-dealers and feed mills.
Working with these partners, CIMMYT scientists also advanced efforts to improve the capacity of actors to increase efficiency in supply chains, production and marketing, provide local employment and strengthen the market for domestically produced maize for poultry feed.
As of September 2022, the following milestones have been achieved:
Provincial governments have established multi-stakeholder maize commercial networks at sites where maize actors and stakeholders participate to coordinate commercial maize production, access to support services and to link farmers and grain buyers.
In 2022, more than 2,000 households from 19 local government units produced maize on 547 ha in Banke, Bardiya and Kailali. The total maize production increased from 1390t in 2021 to 3,232t in 2022. This was an increase of 61% in the number of farmers and 52% in area. The value of maize sold also tripled from USD 306,900 in 2021 to USD 915,700 in 2022.
The farm gate price of maize by 22% and the Government of Nepal invested $2.37 million to support access to quality seed, agriculture machinery and irrigation facilities.
Farmers sold 500t maize grains to feed mills in 2022, a huge jump from only 30t in 2021.
In partnership with the Government of Nepal, CIMMYT researchers organized training programs for farmers in maize commercial network sites on production, post-harvest, exposure visits and marketing to prepare them to produce maize as per buyers’ requirements. They also guided farmers on how to access credit, crop insurance, and digital advisory services to further improve their production and marketing.

Next steps
CIMMYT scientists plan to double the number of districts under the maize commercialization model from three to six in 2023. The Department of Agriculture under the Ministry of Agriculture and Livestock Development, and the local and provincial governments are keen to scale out the model to several maize production regions of Nepal.
In a joint assessment with the Government of Nepal and private sector partners, CIMMYT scientists identified a number of key areas for further development. These include supporting farmers to access high yielding, short duration and stress tolerant maize varieties, as well as best management practices for improving maize production. Other priorities include developing models for contractual arrangements between farmers groups and feed mills, encouraging public and private sector investment in village-level warehouses with drying facilities. Finally, CIMMYT and partners are eager to introduce incentives such as subsidies on grain produced and sold by farmers through cooperatives, develop national maize quality standards and update the 1976 Feed Act.
Going forward, CIMMYT’s research on public private partnership for commercial maize production will focus on drivers of uptake of technology and institutional innovations, the role of aggregation models and contractual arrangements in maize market system coordination and impact assessment on farmers benefits.
Faced with climate change and having to keep pace in the race to feed the world’s growing population, farmers of staple crops like wheat are under pressure to constantly increase yield per hectare.
Increasing yield gains is especially important in Afghanistan, where per capita consumption of wheat is nearly three times more than the global average and wheat accounts for up to 60% of daily caloric intake of the average Afghan citizen.
The International Maize and Wheat Improvement Center (CIMMYT) develops and distributes improved seed targeted toward diverse wheat growing regions in the developing world, including Afghanistan, a net importer of wheat. A study by CIMMYT scientists, published in CropScience, measured yield gain and improvement in a variety of traits of CIMMYT developed varieties compared against local wheat, over a 14-year period. The results showed the CIMMYT varieties confer yield gains, contributing to an increase in Afghanistan’s wheat productivity.
In terms of yield, the CIMMYT varieties showed an increase of 123 kilograms per hectare (kg/ha) over the time interval studied, compared to 107 kg/ha for local varieties.
“This study shows continual increases in yield from CIMMYT varieties across Afghanistan,” said lead author Rajiv Sharma. “This shows the potential of genetically improved germplasm to increase yields, strengthen resistance to diseases and improve other important traits.”
Researchers also examined specific traits, like days to heading and overall plant height. Days to heading refers to the number of days from planting to when the plant is ready to be harvested and overall plant height is the highest measurement a plant reaches. This is important because if a wheat plant grows too high, it will lodge (fall over) under its own weight, rendering it non-harvestable.
Across the CIMMYT varieties there was a 1.8 day per year reduction in days to heading. This is a positive sign for Afghan wheat production as research has shown that crop durations will be reduced because of climate-associated stresses. Shorter crop duration also reduces the cost of crop production, since shorter crop duration reduces the requirements for water, labor, fertilizer, and other resources.
In terms of plant height, the CIMMTY varieties showed a gain of 0.77 cm per year. Although a negative correlation between plant height and grain yield has been reported in other studies, this is not the case in Afghanistan. Increased plant height is often an indicator of higher biomass (the amount of aboveground volume including leaves and stems which might fall to the ground) which drives higher yield, provided the plant does not lodge. Higher biomass is also required in many developing countries, including Afghanistan, to produce straw that is used dry fodder feed for livestock. This appears to result from selections to increase overall production, mitigate negative impacts and fulfil the changing preference of farmers.
“This kind of evaluation is important in determining the efficacy of CIMMYT’s efforts to provide improved wheat varieties tailored to diverse production environments around the world,” said Alison Bentley, co-author of the study and director of CIMMYT’s Global Wheat Program. “It also makes a strong case for continued investment in plant breeding and for the collaboration between Afghanistan and CIMMYT.”
Plant health scientists from The Sainsbury Laboratory, the John Innes Institute at Norwich Research Park, and the International Maize and Wheat Improvement Center (CIMMYT) have collaborated on guidance divided into short-, medium- and long-term priorities, designed to mitigate impending food crises and stabilize wheat supply chains.
In the short-term, wheat production must be increased and wheat flour can be blended with other low-cost cereals. Increasing the local, regional and global resilience of wheat supply is the medium-term solution, while long-term proposals center on ensuring diversity in agro-ecosystems.
In an article for Mexico Business News, Bram Govaerts, Director General of the International Maize and Wheat Improvement Center (CIMMYT), provides context for the organization’s seed systems strategy in relation to current challenges in agriculture.
Despite producing roughly 27 million tons of white maize used each year, Mexico imports approximately 18 million tons of yellow maize for fodder and raw material. To reduce reliance on imports, productivity of staple crops needs to be increased, during a time when climate change, conflict, COVID-19 and cost of living are all causing additional pressures.
Developing seeds with high yields and resilience to the impacts of climate change is required to close yield gaps in a sustainable way. However, the needs of smallholders differ from those of commercial farming, so inclusivity in seed systems is essential.

The Ambassador of Mexico to Norway, Ulises Canchola Gutiérrez, delivered a deposit from the International Maize and Wheat Improvement Center (CIMMYT) to the Svalbard Global Seed Vault on October 12.
CIMMYT was the ninth depositor in the Seed Vault in 2022, with a contribution of 263 accessions of maize and 3,548 accession of wheat.
“Professionally, I am pleased to carry out this activity that contributes to the conservation of genetic resources and guarantees food security of two of the major crops that feed the world,” said Rocio Quiroz, assistant research associate at CIMMYT. “When we prepare a shipment as a team, it is extraordinary because we contribute to the perpetuity of each accession deposited in the vault. Very few people have the privilege of doing so.”

What is the Seed Vault?
The Seed Vault is a genebank collection that holds duplicates of seeds from more than 1,700 genebanks around the world, playing the role of a backup collection. By protecting these varieties from catastrophic loss, the Seed Vault contributes towards food security for future generations.
Owned by Norway and managed in partnership between the Norwegian Ministry of Agriculture and Food, NordGen, and the Crop Trust, the Seed Vault currently holds 1,165,041 seed varieties, with capacity for millions more.
In 2020, CIMMYT was the largest contributor, providing 173,779 maize and wheat accessions from 131 countries.

How is germplasm stored at CIMMYT?
CIMMYT’s own germplasm bank contains approximately 150,000 unique collections of wheat seed and its ancestors and is the largest unified collection in the world for a single crop.
For maize, the germplasm bank contains more than 28,000 samples, including the world’s largest collection of maize landraces, representing nearly 90% of maize diversity in the Americas.
Carolina Sansaloni, manager of the wheat genebank at CIMMYT, said, “I am proud of all CIMMYT germplasm bank staff that made a great effort to send an additional 3,800 accessions to the Svalbard as safety duplications. This contribution is for the food security of humanity.”
