CIMMYT scientists deliver training to improve agriculture in Uzbekistan
Scientists from the Research Institute of Plant Genetic Resources in Uzbekistan (RIPGR) attended training on gene bank management and genetic resources, coordinated by CIMMYT-Türkiye on 13-20 April 2024. Hosted at the Turkish Department of Agricultural Economics and Project Management (TAGEM), the training is supported by the World Bank Group, which is helping Uzbekistan to modernize the country’s agriculture. With one of the highest levels of wheat consumption in Central Asia, the modernization project aims to increase Uzbekistan’s wheat yield and meet demand for the crop.
The course included lectures on status and activity of the Turkish Seed Germplasm Bank (TSGB), policy instruments and international perspectives on plant genetic resources, herbarium techniques, biotechnology studies, and genetic resources. Uzbek scientists also became acquainted with scientific laboratories, visiting the field station in İkizce Gölbaşı and learned about the breeding, pathology, and agronomy activities at the station as well as the collaboration activities between CGIAR Research Centers and TAGEM.
Country-wide expertise
In addition to sessions at CIMMYT’s office in Türkiye, participants also visited the National Gene Bank in Ankara and the National Gene Bank of Izmir.
At the latter location, experts delivered sessions on a range of topics, such as the Plant Diversity and Genetic Resources Program of Türkiye; in vitro and cryopreservation techniques; the conservation, data recording, and documentation of plant genetic resources; conservation and utilization of vegetable genetic resources; conservation studies on mushroom genetic resources; studies on wheat genetic resources and wheat breeding at the international winter wheat breeding program; regional collaboration to combat wheat rust disease in Central and West Asia and North Africa (CWANA); and international winter wheat breeding strategies.
In addition to the seminar sessions, the participants also visited several locations to familiarize themselves with scientific processes in field and laboratory conditions. They visited the field gene banks, guided by Fatih Çağir, who provided brief information about the fruit genetic resources activities of Türkiye. They also visited the plant collection activities and herbarium techniques laboratory, the National Gene Bank, Herbarium, Fungarium & Seed Physiology Laboratory of the Plant Genetics Resources Department & Plant Tissue Center, and the Regional Cereal Rust Research Center.
The importance of the training course for Uzbek scientists is to study the system of rational use, conservation, and management of plant genetic resources of Türkiye and to introduce new innovative knowledge in Uzbekistan. It also consists of discussing aspects related to bilateral cooperation and sustainable development in the field of plant genetic resources as well gene bank management.
The delegation from Uzbekistan, on behalf of the Ministry of Agriculture of the Republic of Uzbekistan, and the director of the Research Institute of Plant Genetic Resources, Zafarjon Mashrapovich Ziyaev, expressed their deep gratitude to the organizers and departments for this training course.
Indian scientists visit Türkiye for soil and root health training program
Soil is the foundation of agriculture, and healthy soil is critical to the entire ecosystem. However, soil health is under threat today as many factors make soil unhealthy, leading to significant losses in farming. CIMMYT in India has been addressing these issues in partnership with national and international institutions, while CIMMYT’s SBP program in Türkiye aims to deliver high-yielding wheat germplasm that is resistant to SBP and supports the International Soil-Borne Pathogens Research & Development Center (ISBPRDC) of Türkiye. It also facilitates knowledge exchange and technology transfer to support joint research and development activities to improve soil health.
On arrival, the group of scientists and professors from Bihar was welcomed by Metin Türker, director general of Agricultural Research and Policies (TAGEM). Talking about the intricate nexus of agriculture, climate, and technology, Türker emphasized varietal developments to irrigation advancements and engaged in lively discussions with the group, fueled by a shared vision for agricultural sustainability.
Led by Abdelfattah A. Dababat, CIMMYT country representative in Türkiye and the leader of the SBD program, the scientists and professors from India ventured into the heart of research institutions, immersing themselves in the latest innovations in wheat improvement and plant pathology. Their journey took them from Ankara to Eskisehir and ended at the Abant Izzet Baysal University, Bolu, where they were greeted by passionate experts eager to share their knowledge. Bonds were forged amid lectures and laboratory demonstrations, and ideas ignited, paving the way for future collaborations.

Thereafter, participants visited the plant pathology laboratory where Abdelfattah A. Dababat and Gül Erginbas-Orakci gave an overview of laboratory methods to study Cereal Cyst Nematodes and Root-Lesion Nematodes with live demonstrations. Innovative approaches to tackle the Plant-Parasitic Nematodes in agriculture were also discussed. In the agronomy laboratory, Oğuz Önder gave a live demonstration for estimating plant grain and biomass yield by optical sensor-based technologies. Participants also had the opportunity to explore the soil science laboratory and become familiar with state-of-the-art equipment used for soil nutrient analysis.
Visit to Bolu
The participants visited Abant Izzet Baysal University, in Bolu, where the Rector Professor. Mustafa Alişarlı welcomed them. This was followed by presentations and discussions on burning issues in agriculture. Professor Senol Yildiz gave a presentation on soil health assessment and management. Professor Halil Kütük of the Department of Plant Protection gave a brief overview of the latest research advancement in biological control of major crop diseases. In continuation, Abdelfattah A. Dababat gave an overview of the cereal cyst nematode and their management. The discussion led to a brainstorming session on soil health management, soil-borne diseases, soil microbiome, and the challenges of using microorganisms for soil health improvements. The major challenges and opportunities for agriculture development under changing climate scenarios in India and Türkiye were also discussed.
The training course exposed participants to the latest research and technologies for soil and root health management to increase agricultural productivity and profitability immediately and into the future. During the entire visit, participants working in different fields (soil science, agronomy, plant breeding, and microbiology) interacted with Türkiye’s expert counterparts to discuss their work and share valuable research insights. Several topics and technologies relevant to global agriculture, like zero tillage, climate-resilient agriculture, precision input management, hidden hunger, and digital agriculture, were discussed. Participants also explored future opportunities for bilateral research collaborations between India and Türkiye.
Participants expressed their deepest gratitude to the CIMMYT team at Türkiye, led by Abdelfattah A. Dababat, for arranging an effective training program and for the support provided at every step. “Your careful planning and thoughtful execution have created an environment where learning flourishes and connections are made. Thank you for your invaluable contribution to our learning journey,” said the participants. Participants also expressed their sincere thanks to the Ministry of Agriculture, Türkiye, and the BISA team for coordinating this training and making the entire experience seamless and impactful for all involved.

Inauguration of the international soil-borne pathogens research & development center in Ankara, Turkey
Soil-borne pathogens (SBP) are a serious threat to Turkey’s food security, especially as climate extremes (temperature, precipitations) become more commonplace. SBP are an array of specific adverse effects, such as root rot, wilt, yellowing, and dwarfing caused by fungi, bacteria, viruses, and nematodes. These pathogens can cause 50-75% yield loss in crops.
On May 2, 2023, the International Maize and Wheat Improvement Center (CIMMYT) Country Representative in Turkey, Abdelfattah Dababat, joined the inauguration ceremony of the International Soil-Borne Pathogens Research & Development Center (ISBPRDC).
Vahit Kirişci, Turkish Minister of Agriculture and Forestry, inaugurated the Center, which is the first of its kind in the Central West Asia and North Africa (CWANA) region dedicated to advancing research on SBPs and developing innovative solutions to control and prevent their spread.
The opening ceremony took place at the Directorate of Plant Protection Central Institute working under the General Directorate of Agricultural Research and Policies (TAGEM), and it was attended by deputy ministers, TAGEM’s DG, and high-level officials of the Ministry of Agriculture and Forestry.
Serving under the auspices of the General Directorate of Agricultural Research and Policies (TAGEM), part of the Turkish Minister of Agriculture and Forestry, the ISBPRDC will meet international standards for sanitary conditions.
CGIAR and TAGEM mutually supported the SBP CIMMYT Turkey program by establishing and funding the ISBPRDC.
Bringing partners together
CIMMYT is signing a collaboration agreement with the ISBPRDC to facilitate knowledge exchange and technology transfer between the two institutions, which will support joint research and development activities aimed at improving crop health and productivity.
“The most effective way forward to battle against threats to food security is through cooperation,” said Dababat. “This collaboration is a great opportunity for Turkey’s seed industry to maintain its competitive advantage in foreign markets.”
Thirty-five scientists and technicians will work at the ISBPRDC and the institute will act as an umbrella for all SBP research in Turkey. Bahri Dağdaş International Agricultural Research Institute (BDIARI), the Transitional Zone Agricultural Research Institute (TZARI), and the Plant Protection Central Research Institute (PPCRI) with offices in Konya, Eskisehir, and Ankara, respectively, will support the ISBPRDC center and collaborate with the SBP program at CIMMYT to deliver high-yielding wheat germplasm that is resistant to SBP.
Among new programs at the center are the development of a robust surveillance system to track pathogens, a genebank for germplasm, and screening facilities for resistance against SBP.
Indian scientists visit CIMMYT Türkiye facility for wheat improvement systems
Scientists from the All India Coordinated Research Project (AICRP) on Wheat and Barley, part of the Indian Council of Agricultural Research (ICAR), and the Mountain Research Centre for Field Crops at Sher-e-Kashmir University of Agricultural Sciences and Technology visited the International Maize and Wheat Improvement Center (CIMMYT) facility in Türkiye on November 14-17.
This trip was an extension of their visit to the Türkiye Akdeniz University, Antalya, under the ICAR-NAHEP overseas fellowship program. The trip to CIMMYT program in Türkiye was with the objective to get exposure to CIMMYT’s germplasm and other new developments in wheat improvement that may be helpful for wheat production in the Northern Hill zone of India, which grows wheat on around 0.8 million hectares.
Ajaz Ahmed Lone, Principal Scientist, Genetics and Plant Breeding at the Dryland Agricultural Research Station, and Shabir Hussain Wani, Scientist, Genetics and Plant Breeding and Principal Investigator, aimed to learn more about CIMMYT’s wheat improvement systems.
After a brief introduction on CIMMYT’s international and soil borne pathogens program in Türkiye by Abdelfattah Dababat, CIMMYT Country Representative for Türkiye and program leader, the visitors met with General Directorate of Agricultural Research and Policies (TAGEM) representative Fatma Sarsu and her team to discuss possible collaboration and capacity building between the two institutions.
Wheat improvement in Türkiye
Lone and Wani also visited the GenBank in Ankara to meet its head, Senay Boyraz Topaloglu, who gave a presentation about the GenBank and highlighted the site’s various facilities.
They then visited the Transitional Zone Agricultural Research Institute (TZARI) in Eskisehir, located in Central Anatolian Plateau of Türkiye, to hear about historical and current studies, particularly within the national wheat breeding program delivered by Head of the Breeding Department, Savas Belen. Belen briefed the visitors about the institute’s facilities, and the collaboration with CIMMYT scientists on wheat breeding activities and germplasm exchange.
Dababat and Gul Erginbas-Orakci, research associate at CIMMYT, presented an overview of soil borne pathogens activities in TZARI-Eskisehir.
Before the visitors departed to Konya, Director of TZARI, Sabri Cakir, welcomed the visitors in his office.
On the final day, the scientists were briefed about Bahri Dagdas International Agricultural Research Institute (BDIARI) through a presentation given by Murat Nadi Tas and Musa Turkoz. Bumin Emre Teke from the animal department presented a European project report on animal breeding, and Mesut Kirbas provided an overview of a European project on e-organic agriculture, as well as visits to the institute’s laboratory and field facilities and the newly established soil borne pathogens field platform.
Dababat said, “It was a fruitful short trip which enabled scientist from SKUAST-Kashmir and CIMMYT-Türkiye to share knowledge about wheat improvement activities and will give way to a road map for future research collaborations between the three institutions.”
Research shows impact of root and crown rot in wheat
Kazakhstan is the ninth largest country in the world and the fourteenth largest producer of wheat; in 2021 alone, the country produced 14.3 million tons (t) of wheat on 12.1 million hectares (ha). Despite this impressive figure, wheat yield in the country falls below average at 1172.5 t/ha compared to 3474.4 t/ha globally.
Research into wheat diseases in Kazakhstan has primarily revolved around airborne fungal foliar diseases, such as stem rust, leaf rust and stripe rust, which can be devastating for farmers and their crops. However, the effects of fungi relating to wheat root and crown root were yet to be examined – these diseases affect yields, stands and grain quality due to infections that cause damping-off, blight, necrosis, and dry rotting.
Using plant samples taken during the 2019 growing season, scientists from the International Maize and Wheat Improvement Center (CIMMYT) conducted a quantitative survey to determine the distribution of this fungi. Using morphological and molecular tools on 1,221 samples from 65 sites across the central, eastern, and southeastern region, scientists found that Bipolaris sorokiniana and Fusarium acuminatum were the most predominant fungal species isolated.
In total, 74 isolates from 16 species were tested, revealing that F. culmorum and F. pseudograminearum, B. sorokinaiana, Fusarium sp., R. solani, F. redolens, C. spicifera, C. inaequalis, and N. orvzae were virulent fungi.
Results show the diverse spectrum of pathogenic fungal species linked to wheat crown and root rot in Kazakhstan and is highly likely to be the first report from the country on the presence of F. seudograminearum, Fusarium sp., C. spicifera, and C. inaequalis.
With this new data, scientists can develop mitigations to prevent crop loss and improve wheat yield across Kazakhstan.

Combatting soil-borne pathogens and nematodes vital for food security
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.
Scientists step up wheat landrace conservation efforts in Afghanistan, Turkey and other countries in the region
For thousands of years, farmers in Afghanistan, Turkey and other countries in the region, have been breeding wheat, working closely with the environment to develop traditional wheat varieties known as landraces. Untouched by scientific breeding, landraces were uniquely adapted to their environment and highly nutritious.
As agriculture became more modernised and intensified, it threatened to push these traditional landraces into extinction, resulting in the loss of valuable genetic diversity. Institutions around the world decided to act, forming germplasm collections known as genebanks to safely house these landraces.
In 2009, a team of wheat scientists from the International Maize and Wheat Improvement Center (CIMMYT), the International Center for Agricultural Research in the Dry Areas (ICARDA), the UN Food and Agriculture Organization (FAO), and national partners set off on a five-year expedition across Central Asia to collect as many landraces as they could find. The project, led by FAO Cereal Breeder and former CIMMYT Principal Scientist Alexey Morgunov, was made possible by the International Treaty on Plant Genetic Resources for Food and Agriculture Benefit-Sharing Fund.
The project had two main missions. The first is to preserve landrace cultivation in three countries, Afghanistan, Turkey and other countries in the region by selecting, purifying, and multiplying the landraces and giving them back to farmers. The second is to scientifically evaluate, characterize and use these landrace varieties in ongoing breeding programmes, exchange the information between the countries, and to deposit the seeds in genebanks to safely preserve them for future generations.
The latest results from the project were published in July in the journal Crops. The study, authored by a team of experts from CIMMYT, ICARDA, FAO, and research institutes in Afghanistan, Turkey and other countries in the region, compared the diversity, performance, and adaptation of the collected wheat landraces with modern varieties grown in the regions using a series of field experiments and cutting-edge genomic tools.
“Landraces are very useful from a breeding perspective because they have been cultivated by farmers over thousands of years and are well adapted to climate change, have strong resistance to abiotic stresses and have very good nutritional quality,” said Rajiv Sharma, a CIMMYT senior scientist and co-author of the paper.
“We were interested in seeing how well landraces adapt to certain environments, how they perform agronomically, and whether they are more diverse than modern varieties grown in these regions – as well as give their improved versions back to farmers before they are lost.”
The experiments, which were carried out in 2018 and 2019 in Turkey, and 2019 in Afghanistan, and other countries in the region revealed several physical characteristics in landraces which are no longer present in modern varieties. For example, the team found striking differences in spike and grain colors with landraces more likely to have red spikes and white grains, and modern varieties tending to have white spikes and red grains. This may have adaptive values for high altitudes and dry conditions.
A surprising finding from the study, however, was that landraces were not more genetically diverse than modern landraces.
“Many people thought that when we went from cultivating landraces to modern varieties, we lost a lot of diversity but genetically speaking, that’s not true. When you look at the genomic profile, modern varieties are just as diverse as landraces, maybe even a little bit more so,” said Sharma.
When the team compared landraces and modern varieties on crop performance, the results were mixed with modern wheat varieties outyielding landraces in half of the environments tested. However, they found that the highest yielding landraces were just as good as the best modern varieties – a reassuring finding for farmers concerned about the productivity of their crops.
A new breeding paradigm
The results of the study have important implications for landrace conservation efforts in farmers’ fields and in future breeding strategies. While crossing wheat landraces with modern varieties to develop improved modern varieties is not new, the authors proposed a novel alternative breeding strategy to encourage the continued cultivation of landraces: improving landraces by crossing them with other landraces.
“In order to maintain landraces, we have to make them competitive and satisfy farmers’ needs and requirements. One option is that we breed landraces,” said Sharma.
“For example, you might have a landrace that is very-high yielding but susceptible to disease. By crossing this variety with another landrace with disease-resistant traits you can develop a new landrace better suited to the farmer and the environment. This approach maintains all the features of landraces – we are simply accelerating the evolution process for farmers to replace the very fast disappearance of these traditional varieties.”
This approach has already been used by crop scientists at the University of California, Davis who has successfully developed and registered “heirloom-like varieties” of dry beans. The varieties trace about 98% of their ancestry to landraces but are resistant to the common mosaic virus.
Heirloom food products are becoming increasingly popular with health-conscious consumers who are willing to pay a higher price for the products, garnering even more interest in conserving traditional landraces.
One of the overarching aims of the project was to give wheat landraces back to farmers and let nature take its course. Throughout the mission, the team multiplied and returned landrace seed to over 1500 farmers in communities across Afghanistan, Turkey and other countries in the region. The team also supplied over 500 farmers with improved landrace seed between 2018 and 2019.
Despite the political turmoil facing these countries, particularly Afghanistan, farmers are still growing wheat and the project’s contribution to food security will continue.
These landraces will take their place once more in the farming landscape, ensuring on-farm wheat diversity and food security for future generations.
This research was conducted with the financial assistance of the European Union within the framework of the Benefit-Sharing Fund project “W2B-PR-41-TURKEY” of the FAO’s International Treaty on Plant Genetic Resources for Food and Agriculture.
How to shockproof staples in a looming global food crisis
The conflict in Ukraine has had a deeply destabilizing effect on the global wheat trade, causing unprecedented price volatility and uncertainty. As my colleagues and I have previously highlighted, the unintended consequences are likely to have outsized impacts on livelihoods in the Global South.
As the G7 group of nations recently acknowledged in a joint statement, the conflict is leading to steep price rises and increasing global food insecurity for millions, especially those most vulnerable, such as women and children.
In a new paper published in Nature Food, scientists and partners of the International Maize and Wheat Improvement Center (CIMMYT) present a package of applied solutions to respond to the crisis and ensure future wheat stability.
To stem the potential food crisis, food is needed in more places, and faster.
Recently announced talks between Russia, Turkey, Ukraine and the United Nations, among other negotiations, are already underway as part of this international effort to develop short-term solutions.
However, at present we are seeing the brakes applied in several places. For example, in India century-high temperature extremes have recently reduced official wheat production estimates by 6 percent, leading to reduced export potential. This shows the compounding effect of climatic instability on global wheat markets, an impact that is expected to worsen over time.
In our solutions agenda, we propose a package of short-, medium- and longer-term actions and urge immediate and sustained support for shockproofing major food security staple crops, including wheat.
- In the short term, the priority is mitigation of food security shocks through boosting production in existing high- and low-productivity areas, ensuring access to grain, and making use of flour substitution.
- In the medium term, we must increase the local, regional, and global resilience of wheat supply through targeted expansion (within agro-ecological boundaries), support for self-sufficiency, comprehensive technical support in production systems, and mainstreamed crop monitoring capacity.
- In the longer term, the transition to agri-food system resilience will need to encompass agroecosystem diversity, address gender disparities in agriculture and rural communities, and sustain an increased investment in a holistic, agri-food transition.
Conflict is being waged on wheat on multiple fronts: on battlefields, in the political arena and by our changing climate. Together these factors interact and amplify the threat to staple wheat production. To address this complexity, we now need to move beyond defining the problem to implementing practical action to ensure stable supply.
How interactions among hidden enemies and drought effects grain yield and disease severity in bread wheat
In nature, plants are simultaneously exposed to a complex system of biotic and abiotic stresses that limit crop yield. The cereal cyst nematode Heterodera filipjevi and dryland crown rot, caused by Fusarium, are important diseases facing cereal production around the world that cause significant yield loss. Yield loss accelerates when those diseases coexist with other abiotic stresses, such as drought.
Hexaploid bread wheat (Triticum aestivum L.) is an essential staple food for a large part of the world’s population, covering around 20% of daily caloric intake in the human diet, with global production at about 670.8 million tons per year, produced over 215.4 million hectares of land worldwide. Therefore, the program studying soil-borne pathogens at the International Maize and Wheat Improvement Center (CIMMYT)’s Turkey office initiated a study to investigate the effect of soil borne diseases (H. filipjevi and Fusarium culmorum) individually and in combination with drought on some morphological and physiological traits in wheat germplasm with different genetic tolerances to the three studied factors.
In this study, yield components included thousand kernel weight, spike weight, seed per spike and total grain yield. Morphological parameters, including plant height, final plant number (seedling emergence), relative water content, leaf chlorophyll content, H. filipjevi cyst number and presence of crown rot, were studied under greenhouse conditions in Turkey.
The main findings of the study showed that the interaction among water stress, F. culmorum and H. filipjevi increased the damage on the wheat parameters studied when compared with each stress applied alone. One of the most significant damages was seen in high seedling mortality under the three combined stresses (56% seedling death rate), which indicates the damage on wheat yield might occur at the seedling stage rather than later stages. This reduces plant density per area, which was ultimately responsible for low grain yield produced. The known dryland disease, crown rot, caused by F. culmorum, was significantly pronounced under water-stressed conditions.
In all studied parameters, the lowest damage was found among the resistant cultivars to biotic or abiotic stresses. This underscores the importance of wheat breeding programs to develop resistant germplasm, and reminds farmers to replace their old, susceptible varieties with new, resistant ones.
Based on our intensive experience in the CWANA region, most wheat growers basically do not recognize soil borne pathogens as a problem. In fact, most of them do not know that what nematode or soil fungal species are in their fields affecting yield. The term “hidden enemy” perfectly applies to the problems in the region and beyond. Integrated pest management (IPM) is, however, not practiced in the entire region and soil borne pathogen-induced yield losses are simply accepted.
We can conclude from this study that yield reduction in wheat due to soil borne pathogens could be lessened by improving and understanding the concept of IPM in the region where the practice of winter mono-culturing of wheat is the norm. Management of cereal soil-borne pathogens, especially cereal cyst nematode and crown rot, could involve an integrated approach that includes crop rotation, genetic resistance, crop nutrition and appropriate water supply.

CIMMYT trains next generation of scientists to tackle soil-borne pathogens
Two new students have graduated from the International Maize and Wheat Improvement Center’s (CIMMYT’s) Soil-Borne Pathogens program. The two new graduates, Khawla Mehalaine and Salah-Eddine Laasli, were supervised by CIMMYT senior scientist Abdelfattah Dababat.
He leads the Soil-Borne Pathogens program, which focuses on identifying the main soil-borne pathogens associated with cereals and developing an integrated pest management approach to combat them. The research team is particularly interested in finding novel sources of resistance against these pathogens.
Over the last two decades, CIMMYT scientists leading the Soil-Borne Pathogens program have trained tens of students which constitute the next generation of top researchers on this topic. Through this program, CIMMYT has also organized workshops and courses in North Africa, including a symposium on cereal nematodes held in Agadir, Morocco, in 2017.
Since soil-borne pathogens are exacerbated by water stress conditions, researchers have identified the Central and West Asia and North Africa regions as priority areas, due to their vulnerability to drought.
On March 1, 2021, Syngenta, in collaboration with CIMMYT and other partners, led the first One Earth Soil and Root Health Forum, an event which examined the importance of root and soil health to food security, climate resilience and livelihoods. The event also created a community for action on root and soil health.
Nematodes in Algeria
Mehalaine holds an engineering degree in agronomy and a master’s degree in plant protection from the Higher National School of Agronomy (ENSA) in Algeria. She successfully defended her PhD dissertation “Studies of cereal cyst nematodes of the genus Heterodera in the regions of northern Algeria” in June 2021, graduating from ENSA with honors.
She studied the behavior of four durum wheat varieties against cereal cyst nematodes through field surveys, molecular identification at species levels, and by evaluating the yield components of these wheat varieties.
She was promoted by ENSA professor Hammach M. and supervised by Dababat from CIMMYT, and professors Mustafa Imren and Göksel Özer from Abant Izzet Baysal University in Turkey.
“Completing my doctorate was a truly enriching experience and a challenging but rewarding journey,” Mehalaine said. “It was a collective effort and I am extremely grateful to Dr Abdelfattah Dababat for sharing his scientific skills, for his patience and support, and for all the opportunities I was given to further my research. Thanks to him, I got to know the world of nematodes. Special thanks to CIMMYT for funding the molecular study part.”
Root-lesion nematode and crown rot fungi
Laasli graduated with an International Master of Agronomic and Environmental Nematology (IMANEMA) from Ghent University, in collaboration with CIMMYT, the National Institute of Agricultural Research in Morocco and the Faculty of Agriculture at Abant Izzet Baysal University in Turkey.
His master thesis, entitled “Interaction of Root-Lesion Nematode (Pratylenchus thornei) and Crown Rot fungi (Fusarium culmorum) associated with wheat resistance under simulated field conditions,” was promoted by Wim Bert, a professor at the University of Ghent, and Dababat. The project was also supervised by Imren and Özer.
Laasli evaluated the host status of 150 spring wheat lines to both P. thornei and F. culmorum, and estimated the damage caused by the disease complex involving both pathogens at different infection scenarios. He found several lines that possessed multiple resistance to both diseases tested — which could be powerful sources of resistance for breeding program worldwide.

A challenge solved
For scientists, determining how best to increase wheat yields to meet food demand is a persistent challenge, particularly as the trend toward sustainably intensifying production on agricultural lands grows.
The United Nations projects that the current global population of 7.6 billion will increase to more than 9.8 billion by 2050, making higher grain yield potential vital, particularly as climate instability increases due to global warming. International efforts are also focused on meeting the Zero Hunger target detailed in the UN Sustainable Development Goals before they expire in 2030.
Now, a new landmark research survey on the grain yield potential and climate-resilience of bread wheat (Triticum aestivum L.) has brought scientists a few strides closer to meeting their ambitions.
Grain yield has traditionally been an elusive trait in genomic wheat breeding because of its quantitative genetic control, which means that it is controlled by many genomic regions with small effects.
Challenges also include a lack of good understanding about the genetic basis of grain yield, inconsistent grain yield quantitative trait loci identified in different environments, low heritability of grain yield across environments and environment interactions of grain yield.
To dissect the genetic architecture of wheat grain yield for the purposes of the research, which appeared in Scientific Reports, researchers implemented a large-scale genome-wide association study based on 100 datasets and 105,000 grain yield observations from 55,568 wheat breeding lines developed by the International Maize and Wheat Improvement Center (CIMMYT).
They evaluated the lines between 2003 and 2019 in different sites, years, planting systems, irrigation systems and abiotic stresses at CIMMYT’s primary yield testing site, the Norman E. Borlaug Experimental Research Station, Ciudad Obregon, Mexico, and in an additional eight countries — including Afghanistan, India and Myanmar — through partnerships with national programs.
The researchers also generated the grain-yield associated marker profiles and analyzed the grain-yield favorable allele frequencies for a large panel of 73,142 wheat lines, resulting in 44.5 million data points. The marker profiles indicated that the CIMMYT global wheat germplasm is rich in grain yield favorable alleles and is a trove for breeders to choose parents and design strategic crosses based on complementary grain yield alleles at desired loci.
“By dissecting the genetic basis of the elusive grain-yield trait, the resources presented in our study provide great opportunities to accelerate genomic breeding for high-yielding and climate-resilient wheat varieties, which is a major objective of the Accelerating Genetic Gain in Maize and Wheat project,” said CIMMYT wheat breeder Philomin Juliana.
“This study is unique and the largest-of-its-kind focusing on elucidating the genetic architecture of wheat grain yield,” she explained, “a highly complex and economically important trait that will have great implications on future diagnostic marker development, gene discovery, marker-assisted selection and genomic-breeding in wheat.”
Currently, crop breeding methods and agronomic management put annual productivity increases at 1.2% a year, but to ensure food security for future generations, productivity should be at 2.4% a year.
So, the extensive datasets and results presented in this study are expected to provide a framework for breeders to design effective strategies for mitigating the effects of climate change, while ensuring food-sustainability and security.
“CIMMYT is at my heart”
After a 37-year career, Hans-Joachim Braun is retiring from the International Maize and Wheat Improvement Center (CIMMYT). As the director of the Global Wheat Program and the CGIAR Research Program on Wheat, Braun’s legacy will resonate throughout halls, greenhouses and fields of wheat research worldwide.
We caught up with him to capture some of his career milestones, best travel stories, and vision for the future of CIMMYT and global wheat production. And, of course, his retirement plans in the German countryside.
Major career milestones
Native to Germany, Braun moved to Mexico in 1981 to complete his PhD research at CIMMYT’s experimental station in Obrégon, in the state of Sonora. His research focused on identifying the optimum location to breed spring wheat for developing countries — and he found that Obrégon was in fact the ideal location.
His first posting with CIMMYT was in Turkey in 1985, as a breeder in the International Winter Wheat Improvement Program (IWWIP). This was the first CGIAR breeding program hosted by a CIMMYT co-operator, that later developed into the joint Turkey, CIMMYT and the International Center for Agricultural Research in the Dry Areas (ICARDA) winter wheat program. “In 1990, when the Commonwealth of Independent States was established, I saw this tremendous opportunity to work with Central Asia to develop better wheat varieties,” he said. “Today, IWWIP varieties are grown on nearly 3 million hectares.”
Although Braun was determined to become a wheat breeder, he never actually intended to spend his entire career with one institution. “Eventually I worked my entire career for CIMMYT. Not so usual anymore, but it was very rewarding. CIMMYT is at my heart; it is what I know.”
“Make the link to the unexpected”
One of Braun’s standout memories was a major discovery when he first came to Turkey. When evaluating elite lines from outside the country — in particular lines from a similar environment in the Great Plains — his team noticed they were failing but nobody knew why.
Two of his colleagues had just returned from Australia, where research had recently identified micronutrient disorders in soil as a major constraint for cereal production. The team tried applying micro-nutrients to wheat plots, and it became crystal clear that zinc deficiency was the underlying cause. “Once aware that micro-nutrient disorders can cause severe growth problems, it was a minor step to identify boron toxicity as another issue. Looking back, it was so obvious. The cover picture of a FAO book on global soil analysis showed a rice field with zinc deficiency, and Turkey produces more boron than the rest of the world combined.”
“We tested the soil and found zinc deficiency was widespread, not just in the soils, but also in humans.” This led to a long-term cooperation with plant nutrition scientists from Cukurova University, now Sabanci University, in Istanbul.
But zinc deficiency did not explain all growth problems. Soil-borne diseases — cyst and lesion nematodes, and root and crown rot — were also widespread. In 1999, CIMMYT initiated a soil-borne disease screening program with Turkish colleagues that continues until today. Over the coming decade, CIMMYT’s wheat program will make zinc a core trait and all lines will have at least 25% more zinc in the grain than currently grown varieties.
After 21 years in Turkey, Braun accepted the position as director of CIMMYT’s Global Wheat Program and moved back to Mexico.
Partnerships and friendships
Braun emphasized the importance of “mutual trust and connections,” especially with cooperators in the national agricultural research systems of partner countries. This strong global network contributed to another major milestone in CIMMYT wheat research: the rapid development and release of varieties with strong resistance to the virulent Ug99 race of wheat rust. This network, led by Cornell University, prevented a potential global wheat rust epidemic.
CIMMYT’s relationship with Mexico’s Ministry of Agriculture and the Obregón farmers union, the Patronato, is especially important to Braun.
In 1955, Patronato farmers made 200 hectares of land available, free if charge, to Norman Borlaug. The first farm community in the developing world to support research, it became CIMMYT’s principal wheat breeding experimental station: Norman Borlaug Experimental Station, or CENEB. When Borlaug visited Obregón for the last time in 2009, the Patronato farmers had a big surprise.
“I was just getting out of the shower in my room in Obregón when I got a call from Jorge Artee Elias Calles, the president of the Patronato,” Braun recalls. “He said, ‘Hans, I’m really happy to inform you that Patronato decided to donate $1 million.’”
The donation, in honor of Borlaug’s lifetime of collaboration and global impact, was given for CIMMYT’s research on wheat diseases.
“This relationship and support from the Obregón farmers is really tremendous,” Braun says. “Obregón is a really special place to me. I am admittedly a little bit biased, because Obregón gave me a PhD.”

A worldwide perspective
Braun’s decades of international research and travel has yielded just as many stories and adventures as it has high-impact wheat varieties.
He remembers seeing areas marked with red tape as he surveyed wheat fields in Afghanistan in the 1990s, and the shock and fear he felt when he was informed that they were uncleared landmine areas. “I was never more scared than in that moment, and I followed the footsteps of the guy in front of me exactly,” Braun recalls.
On a different trip to Afghanistan, Braun met a farmer who had struggled with a yellow rust epidemic and was now growing CIMMYT lines that were resistant to it.
“The difference between his field and his neighbors’ was so incredible. When he learned I had developed the variety he was so thankful. He wanted to invite me to his home for dinner. Interestingly, he called it Mexican wheat, as all modern varieties are called there, though it came from the winter wheat program in Turkey.”
Seeing the impact of CIMMYT’s work on farmers was always a highlight for Braun.
CIMMYT’s future
Braun considers wheat research to be still in a “blessed environment” because a culture of openly-shared germplasm, knowledge and information among the global wheat community is still the norm. “I only can hope this is maintained, because it is the basis for future wheat improvement.”
His pride in his program and colleagues is clear.
“A successful, full-fledged wheat breeding program must have breeders, quantitative genetics, pathology, physiology, molecular science, wide crossing, quality, nutrition, bioinformatics, statistics, agronomy and input from economists and gender experts,” in addition to a broad target area, he remarked at an acceptance address for the Norman Borlaug Lifetime Achievement award.
“How many programs worldwide have this expertise and meet the target criteria? The Global Wheat Program is unique — no other wheat breeding program has a comparable impact. Today, around 60 million hectares are sown with CIMMYT-derived wheat varieties, increasing the annual income of farmers by around $3 billion dollars. Not bad for an annual investment in breeding of around $25 million dollars. And I don’t take credit for CIMMYT only, this is achieved through the excellent collaboration we have with national programs.”
A bright future for wheat, and for Braun
After retirement, Braun is looking forward to settling in rural Inzlingen, Germany, and being surrounded by the beautiful countryside and mountains, alongside his wife Johanna. They look forward to skiing, running, e-biking and other leisure activities.
“One other thing I will try — though most people will not believe me because I’m famous for not cooking — but I am really looking into experimenting with flour and baking,” he says.
Despite his relaxing retirement plans, Braun hopes to continue to support wheat research, whether it is through CIMMYT or through long friendships with national partners, raising awareness of population growth, the “problem of all problems” in his view.
“We have today 300 million more hungry people than in 1985. The road to zero hunger in 2030 is long and will need substantial efforts. In 1970, Organization for Economic Co-Operation and Development (OECD) countries agreed to spend 0.7% of GDP on official development assistance. Today only 6 countries meet this target and the average of all OECD countries has never been higher than 0.4%. Something needs to change to end extreme poverty — and that on top of COVID-19. The demand for wheat is increasing, and at the same time the area under wheat cultivation needs to be reduced, a double challenge. We need a strong maize and wheat program. The world needs a strong CIMMYT.”

The end of an era: Alexey Morgunov retires after a 28-year career
At the end of 2019, the International Maize and Wheat Improvement Center (CIMMYT) will say goodbye to Alexey Morgunov, head of the International Winter Wheat Improvement Program (IWWIP) in Turkey.
A native of Russia, Morgunov joined CIMMYT as a spring wheat breeder in 1991 working with Sanjaya Rajaram, former Global Wheat Program director and World Food Prize laureate. Morgunov went on to work as a breeder of winter wheat in Turkey in 1994 and later to Kazakhstan, where he helped generate new wheat varieties and technologies for Central Asia and the Caucasus region.
Since 2006 he has led the International Winter Wheat Improvement Program (IWWIP), a highly-productive collaboration between Turkey, the International Center for Research in Dry Areas (ICARDA), and CIMMYT.
As part of that program, Morgunov contributed to the development of more than 70 widely grown wheat varieties in Central and West Asia and, in 2013, to a national wheat landrace inventory in Turkey. He has also helped develop and characterize synthetic wheats — created by crossing modern durum wheat with grassy relatives of the crop — and used them in breeding to broaden the diversity of winter wheat.
A professional journey across Central Asia
Morgunov said his childhood in rural Russia instilled in him the importance of agriculture and of education.
“My parents, who lived in rural Russia, went through hunger and were trying to make sure that their children worked somewhere close to food production so that we wouldn’t go hungry,” he explained. “They said: ‘OK, Alex, you go to an agricultural university and you will not be hungry.’ ”
After his university studies, Morgunov joined the Plant Breeding Institute at Cambridge as a visiting scientist in the late 1980s, where he crossed paths with CIMMYT scientists seeking to partner with the newly independent states of the former Soviet Union. After an interview in 1991, he was invited to join the CIMMYT team in Mexico as a wheat breeder.
He was later posted to Kazakhstan to build relationships in Central Asia, a period he cites as a standout. “In the late 90s CIMMYT started working with Central Asian countries experiencing severe food security issues,” he said. “They didn’t really have any technologies or varieties for grain production, so we started a program in 95/96 which later developed into a CGIAR program.”
“We had great impact in those countries at the time, introducing zero tillage in Kazakhstan, new seed varieties in Tajikistan after the civil war, and high-yielding rust-resistant varieties to Uzbekistan.”
Reflecting on his time at CIMMYT, it was the friends and connections he made that stood out the most for Morgunov.
“The thing I most enjoyed was communicating with colleagues,” Morgunov said. “You start working in Kazakhstan and other places and building up cooperation and technical relationships and, over time, these relationships become friendships that we enjoy for as long as we live. I think this is very satisfactory for us as human beings.”
Last month, Morgunov received a fellowship from the Crop Science Society of America. The award is the highest recognition granted by the association.
Active retirement
Despite his plans to retire, Morgunov still plans to continue working — but on his own terms. “My wife is from Kazakhstan so we will be moving there and I plan to continue working in a different capacity and different schedule,” he explains. “Some Russian universities are writing to me to participate in projects and also universities from Kazakhstan. I have a couple of PhD students in Kazakhstan so I’d like to move more into the educational side of things, working with younger people.”
He was also given an Adjunct Faculty position by Washington State University early this year and will volunteer for them.
Morgunov has also recommended that CIMMYT creates an “emeritus” status for long-serving colleagues retiring from the organization, so they can continue to support the organization.
It won’t be all work though. Morgunov is a devoted tennis player and plans to improve his backhand. A keen sailor, he also hopes to spend more time on the waves and visiting new countries.
