As a fast growing region with increasing challenges for smallholder farmers, Asia is a key target region for CIMMYT. CIMMYTâs work stretches from Central Asia to southern China and incorporates system-wide approaches to improve wheat and maize productivity and deliver quality seed to areas with high rates of child malnutrition. Activities involve national and regional local organizations to facilitate greater adoption of new technologies by farmers and benefit from close partnerships with farmer associations and agricultural extension agents.

Today the Weed Science Society of America (WSSA) announced the Honorary Member award for Ram Kanwar Malik, senior scientist at the International Maize and Wheat Improvement Center (CIMMYT). This award is given every year to a person who has made outstanding contributions to weed science âthrough their research, teaching, publishing and outreach.â
Malik’s early engagement in agricultural sustainability led to initiatives exploring herbicide resistance evolution and management, zero tillage, and other resource-conservation technologies. At the Cereal Systems Initiative for South Asia (CSISA) â a regional project led by CIMMYT â Malik and his colleagues helped promote the practice of early wheat sowing to beat terminal heat stress, resulting in increased wheat yield in Indiaâs eastern Indo-Gangetic Plains.
“WSSA’s Honorary Member award is one of the highest recognitions bestowed by the Weed Science Society of America,â said Krishna Reddy, Chair of the WSSA 2022 Award Committee. â[The] Honorary Member is selected for meritorious service to weed science, among non-members from North America or any weed scientist from other countries. Only one person per year is awarded this membership. Dr. Malik’s significant research in weed science and his collaborative effort to deliver solutions for farmers in developing countries like India is inspirational.”
Phalaris minor is a pernicious weed that affects crops like wheat and substantially reduces its yield potential.
Malik has worked extensively in the Indo-Gangetic Plains, leading many initiatives and innovations over the years, in collaboration with national and international partners. The WSSA award highlights Malik’s inspiring work in tackling herbicide resistance problems, first reported in India by his team in 1993. Malik was instrumental in developing a management solution for herbicide-resistant Phalaris minor, a pernicious weed in wheat crops. The integrated weed management system he helped develop raised wheat yield capacity significantly for farmers in the Indo-Gangetic Plains.
“The WSSA Honorary Member award reiterates the importance of agronomic management for sustained weed control strategies across cropping systems,” Malik said. “CIMMYT and partners, including the Australian Centre for International Agricultural Research (ACIAR), were the first to introduce zero tillage in wheat as part of a strategy to manage weed resistance problems in India. It is an honor that WSSA has recognized this collective work of ours,” he acknowledged.
Malik has devoted more than thirty years to transforming agricultural systems in the Indo-Gangetic Plains, working closely with farmers and partners, and building the capacity of national agricultural and research extension systems. he is a firm believer in farmers’ participation: “Large-scale adoption of sustainable agricultural practices is possible when we work together to leverage technologies which are mutually agreed by partners and meet farmers’ needs.”
Malik is a fellow of the Indian Society of Agronomy and the Indian Society of Weed Science (ISWS), which granted him the Lifetime Achievement Award. He has also received the Outstanding Achievement Award from the International Weed Science Society (IWSS) and the 2015 Derek Tribe Award from the Crawford Fund.
He remains passionate about and invested in changing the lives of farmers through better-bet agronomy and by leading innovative research at CIMMYT.

Researchers at the International Maize and Wheat Improvement Center (CIMMYT) have studied and witnessed that women, particularly in South Asia, have strongly ingrained and culturally determined gender roles.
While women play a critical part in agriculture, their contributions are oftentimes neglected and underappreciated. Is there any way to stop this?
On International Day of Women and Girls in Science, we spoke to Pragya Timsina about how womenâs participation in agriculture is evolving across the Eastern Gangetic Plains and her findings which will be included in a paper coming out later this year: âNecessity as a driver of bending agricultural gender norms in South Asiaâ. Pragya is a Social Researcher at CIMMYT, based in New Delhi, India. She has worked extensively across different regions in India and is currently involved in various projects in India, Nepal and Bangladesh.
What is the current scenario in the Eastern Gangetic Plains of South Asia on gender disparities and womenâs involvement in agriculture? Is it the same in all locations that your research covered?
Currently, traditional roles, limited mobility, societal criticism for violating gender norms, laborious unmechanized agricultural labor, and unacknowledged gender roles are among the social and cultural constraints that women face in the Eastern Gangetic Plains. Our research shows that while these norms exist throughout the Eastern Gangetic Plains, there are outliers, and an emerging narrative that is likely to lead to further bending (but not breaking, yet) of such norms.
Are there any factors that limit women from participating in agriculture?Â
Cultural and religious norms have influence gender roles differently in different households but there are definitely some common societal trends. Traditionally, women are encouraged to take on roles such as household chores, childcare, and livestock rearing, but our research in the Eastern Gangetic Plains found that in specific regions such as Cooch Behar (West Bengal), women were more actively involved in agriculture and even participated in women-led village level farmers’ groups.
How or what can help increase womenâs exposure to agricultural activities?
At the community level, causes of change in gender norms include the lack of available labor due to outmigration, the necessity to participate in agriculture due to a labor shortage, and a greater understanding and exposure to others who are not constrained by gendered norms. There are instances where women farmers are provided access and exposure to contemporary and enhanced technology advances, information, and entrepreneurial skills that may help them become knowledgeable and acknowledged agricultural decision makers. In this way, research projects can play an important role in bending these strongly ingrained gendered norms and foster change.
In a context where several programs are being introduced to empower women in agriculture, why do you think they havenât helped reduce gender inequality?
Our study reveals that gender norms that already exist require more than project assistance to transform.
While some women in the Eastern Gangetic Plains have expanded their engagement in public places as they move away from unpaid or unrecognized labor, this has not always mirrored shifts in their private spaces in terms of decision-making authority, which is still primarily controlled by men.
Although, various trends are likely to exacerbate this process of change, such as a continued shortage of available labor and changing household circumstances due to male outmigration, supportive family environments, and peer support.
What lessons can policymakers and other stakeholders take away to help initiate gender equality in agriculture?
Although gender norms are changing, I believe they have yet to infiltrate at a communal and social level. This demonstrates that the bending of culturally established and interwoven systemic gender norms across the Eastern Gangetic Plains are still in the early stages of development. To foster more equitable agricultural growth, policymakers should focus on providing inclusive exposure opportunities for all community members, regardless of their standing in the household or society.
What future do the women in agriculture perceive?
Increasing development projects are currently being targeted towards women. In certain circumstances, project interventions have initiated a shift in community attitudes toward women’s participation. There has been an upsurge in women’s expectations, including a desire to be viewed as equal to men and to participate actively in agriculture. These patterns of women defying gender norms appear to be on the rise.
What is your take on womenâs participation in agriculture, to enhance the desire to be involved in agriculture?
Higher outmigration, agricultural labor shortages, and increased shared responsibilities, in my opinion, are likely to expand rural South Asian women’s participation in agricultural operations but these are yet to be explored in the Eastern Gangetic Plains. However, appropriate policies and initiatives must be implemented to ensure continued and active participation of women in agriculture. When executing any development projects, especially in the Eastern Gangetic Plains, policies and interventions must be inclusive, participatory, and take into account systemic societal norms that tend to heavily impact women’s position in the society.
On this International Day of Women and Girls in Science, CIMMYT speaks to Tripti Agarwal, whose research paper delves into the impact of Climate-Smart Agricultural Practices (CSAPs) on women and farming households in Bihar, India. CSAPs offer a promising solution to address environmental issues through gender-inclusive technological interventions. As we celebrate the achievements of women in science today, we see CSAPs bridging the gender gap and empowering women.
Hello Tripti, it’s great to talk to you about labor migration and how the adoption of CSAPs ensures household food security. Could you share how this approach influences gender equality in farming households?Â
My paper is titled “Gendered impacts of climate-smart agriculture on household food security and labor migration: insights from Bihar, India.” Bihar is highly vulnerable to hydro-meteorological natural disasters that cause agricultural production loss. The issue is that the male workforce migrates to other cities to seek different employment opportunities and improve their families’ livelihoods, often leaving the women behind to farm. Women left behind are then responsible for household and farming activities, making them overburdened. Therefore, Climate Smart Agricultural Practices (CSAPs) could play a vital role in safeguarding the loss in production and supporting livelihoods. The concept of Climate-Smart Villages (CSVs) links this, acknowledging the gender gap and striving to promote gender-equitable approaches in knowledge enhancement, capacity development, and better practices. CSAPs empower women to support farming decision-making and a better utilization of resources
That is interesting. Would you also tell us how the CSV program addresses climatic risks from technological and social perspectives?Â
As per the study I mentioned earlier, climatic stress that affects crop production directly impacts a household’s food security and, more severely, women’s food security. The CSV program promotes adopting climate-resilient practices and technologies that mitigate the risk of crop loss and ensure enough food for the household. CSV is a promising solution to address environmental issues through gender-inclusive technological interventions.
Ensuring food for the household is the most important thing. We also see that this paper highlighted the knowledge gaps between men and women farmers in terms of CSAPs. What action plan is needed to have a more equitable gender-responsive environment at the policy level?Â
The paper attempts to drive the concentration of the state/policymakers in providing more opportunities to women in having access to resources. Policies or strategies â driven towards ensuring female education, knowledge and capacity building â are likely to play a significant role in providing access and control of resources to women across their lifetimes in varied areas of work.
As per the research paper, the probability of out-migration is reduced by 21% with the adoption of CSAPs. What factors do you think are the critical indicators of this trend?Â
The increase in knowledge about CSAPs, both for men and women, supports household decision-making in adopting CSAPs. With the adoption of CSAPs, the increase in agricultural production reduced the compulsion of males to migrate, and better female literacy also had a negative and significant effect on male out-migration
The study also reveals that the farmer’s education has a direct impact on the adoption of CSAPs. Is there any plan to bridge this gap? Or a suggestion for the policy makers to address this issue?Â
There are two steps to be covered on this front. First, to have gender-equitable knowledge dissemination and to ensure that women receive the required and necessary information about CSAPs. For this, the role of women in society needs to be strengthened and would primarily come from (i) support from the family & society and (ii) right to education. Second, knowledge alone is not enough to contribute to economic activities. Gender-inclusive strategies need to be framed and implemented to provide women the required access and control over resources. For this, multi-sectoral efforts are necessary, like having policies from the government, corporates supporting the cost of efforts, specialized agencies providing the expertise, NGO partners working with the community, and foremost, support from the society.
Very rightly said, and we hope that some strong measures are taken at the policy level. Today, women play a huge role in agriculture; thus, it becomes vital to enhance their capacities, especially in newer technologies. In this context, what approaches can you suggest to strengthening their skills and knowledge to achieve a gender-empowered agricultural domain?Â
There is no limit to enhancing the skills and capacities of an individual. And when we talk about women, especially in rural/agricultural contexts, we see that support from the family is critical for them. To ensure that, we need ways to educate men on how women can support them in providing better livelihoods. Creating plans and roadmaps for women would help achieve a gender-empowered agricultural domain, but we must also bring behavior change among men towards a more accepting role of women in farming and decision making.
One last question related to this special day. Why do you love your work? And how is science exciting for you?
I was assigned the position of Project Administrator; however, after working for many years with a team of experts, my interest in research slowly ignited. Thanks to the support I received, I decided to work closely on the subject and identify the areas where I may add value. Linking my knowledge and field studies, I started contributing to relevant publications like this one, which is the output of my years of experience at CIMMYT. I received a lot of support from my team, especially from Dr. M.L. Jat, who has been a great mentor throughout my journey of learning and growth.
M.L. Jat is a Principal Scientist at CIMMYT and co-author of the article. Building on this publication, CIMMYT’s gender research will be further strengthened under the One CGIAR Regional Integrated Initiative on Transforming Agri-Food Systems in South Asia (TAFSSA), which has a core learning site in Bihar.
Emerging in the last 120 years, science-based plant breeding begins by creating novel diversity from which useful new varieties can be identified or formed. The most common approach is making targeted crosses between parents with complementary, desirable traits. This is followed by selection among the resulting plants to obtain improved types that combine desired traits and performance. A less common approach is to expose plant tissues to chemicals or radiation that stimulate random mutations of the type that occur in nature, creating diversity and driving natural selection and evolution.
Determined by farmers and consumer markets, the target traits for plant breeding can include improved grain and fruit yield, resistance to major diseases and pests, better nutritional quality, ease of processing, and tolerance to environmental stresses such as drought, heat, acid soils, flooded fields and infertile soils. Most traits are genetically complex â that is, they are controlled by many genes and gene interactions â so breeders must intercross and select among hundreds of thousands of plants over generations to develop and choose the best.
Plant breeding over the last 100 years has fostered food and nutritional security for expanding populations, adapted crops to changing climates, and helped to alleviate poverty. Together with better farming practices, improved crop varieties can help to reduce environmental degradation and to mitigate climate change from agriculture.
Is plant breeding a modern technique?
Plant breeding began around 10,000 years ago, when humans undertook the domestication of ancestral food crop species. Over the ensuing millennia, farmers selected and re-sowed seed from the best grains, fruits or plants they harvested, genetically modifying the species for human use.
Modern, science-based plant breeding is a focused, systematic and swifter version of that process. It has been applied to all crops, among them maize, wheat, rice, potatoes, beans, cassava and horticulture crops, as well as to fruit trees, sugarcane, oil palm, cotton, farm animals and other species.
With modern breeding, specialists began collecting and preserving crop diversity, including farmer-selected heirloom varieties, improved varieties and the cropsâ undomesticated relatives. Today hundreds of thousands of unique samples of diverse crop types, in the form of seeds and cuttings, are meticulously preserved as living catalogs in dozens of publicly-administered âbanks.â
The International Maize and Wheat Improvement Center (CIMMYT) manages a germplasm bank containing more than 180,000 unique maize- and wheat-related seed samples, and the Svalbard Global Seed Vault on the Norwegian island of Spitsbergen preserves back-up copies of nearly a million collections from CIMMYT and other banks.
Through genetic analyses or growing seed samples, scientists comb such collections to find useful traits. Data and seed samples from publicly-funded initiatives of this type are shared among breeders and other researchers worldwide. The complete DNA sequences of several food crops, including rice, maize, and wheat, are now available and greatly assist scientists to identify novel, useful diversity.
Much crop breeding is international. From its own breeding programs, CIMMYT sends half a million seed packages each year to some 800 partners, including public research institutions and private companies in 100 countries, for breeding, genetic analyses and other research.
Early in the 20th century, plant breeders began to apply the discoveries of Gregor Mendel, a 19th-century mathematician and biologist, regarding genetic variation and heredity. They also began to take advantage of heterosis, commonly known as hybrid vigor, whereby progeny of crosses between genetically different lines will turn out stronger or more productive than their parents.
Modern statistical methods to analyze experimental data have helped breeders to understand differences in the performance of breeding offspring; particularly, how to distinguish genetic variation, which is heritable, from environmental influences on how parental traits are expressed in successive generations of plants.
Since the 1990s, geneticists and breeders have used molecular (DNA-based) markers. These are specific regions of the plantâs genome that are linked to a gene influencing a desired trait. Markers can also be used to obtain a DNA âfingerprintâ of a variety, to develop detailed genetic maps and to sequence crop plant genomes. Many applications of molecular markers are used in plant breeding to select progenies of breeding crosses featuring the greatest number of desired traits from their parents.
Plant breeders normally prefer to work with âeliteâ populations that have already undergone breeding and thus feature high concentrations of useful genes and fewer undesirable ones, but scientists also introduce non-elite diversity into breeding populations to boost their resilience and address threats such as new fungi or viruses that attack crops.
Transgenics are products of one genetic engineering technology, in which a gene from one species is inserted in another. A great advantage of the technology for crop breeding is that it introduces the desired gene alone, in contrast to conventional breeding crosses, where many undesired genes accompany the target gene and can reduce yield or other valuable traits. Transgenics have been used since the 1990s to implant traits such as pest resistance, herbicide tolerance, or improved nutritional value. Transgenic crop varieties are grown on more than 190 million hectares worldwide and have increased harvests, raised farmersâ income and reduced the use of pesticides. Complex regulatory requirements to manage their potential health or environmental risks, as well as consumer concerns about such risks and the fair sharing of benefits, make transgenic crop varieties difficult and expensive to deploy.
Genome editing or gene editing techniques allow precise modification of specific DNA sequences, making it possible to enhance, diminish or turn off the expression of genes and to convert them to more favorable versions. Gene editing is used primarily to produce non-transgenic plants like those that arise through natural mutations. The approach can be used to improve plant traits that are controlled by single or small numbers of genes, such as resistance to diseases and better grain quality or nutrition. Whether and how to regulate gene edited crops is still being defined in many countries.

Selected impacts of maize and wheat breeding
In the early 1990s, a CIMMYT methodology led to improved maize varieties that tolerate moderate drought conditions around flowering time in tropical, rainfed environments, besides featuring other valuable agronomic and resilience traits. By 2015, almost half the maize-producing area in 18 countries of sub-Saharan Africa â a region where the crop provides almost a third of human calories but where 65% of maize lands face at least occasional drought â was sown to varieties from this breeding research, in partnership with the International Institute of Tropical Agriculture (IITA). The estimated yearly benefits are as high as $1 billion.
Intensive breeding for resistance to Maize Lethal Necrosis (MLN), a viral disease that appeared in eastern Africa in 2011 and quickly spread to attack maize crops across the continent, allowed the release by 2017 of 18 MLN-resistant maize hybrids.
Improved wheat varieties developed using breeding lines from CIMMYT or the International Centre for Agricultural Research in the Dry Areas (ICARDA) cover more than 100 million hectares, nearly two-thirds of the area sown to improved wheat worldwide, with benefits in added grain that range from $2.8 to 3.8 billion each year.
Breeding for resistance to devastating crop diseases and pests has saved billions of dollars in crop losses and reduced the use of costly and potentially harmful pesticides. A 2004 study showed that investments since the early 1970s in breeding for resistance in wheat to the fungal disease leaf rust had provided benefits in added grain worth 5.36 billion 1990 US dollars. Global research to control wheat stem rust disease saves wheat farmers the equivalent of at least $1.12 billion each year.
Crosses of wheat with related crops (rye) or even wild grasses â the latter known as wide crosses â have greatly improved the hardiness and productivity of wheat. For example, an estimated one-fifth of the elite wheat breeding lines in CIMMYT international yield trials features genes from Aegilops tauschii, commonly known as âgoat grass,â that boost their resilience and provide other valuable traits to protect yield.
Biofortification â breeding to develop nutritionally enriched crops â has resulted in more than 60 maize and wheat varieties whose grain offers improved protein quality or enhanced levels of micro-nutrients such as zinc and provitamin A. Biofortified maize and wheat varieties have benefited smallholder farm families and consumers in more than 20 countries across sub-Saharan Africa, Asia, and Latin America. Consumption of provitamin-A-enhanced maize or sweet potato has been shown to reduce chronic vitamin A deficiencies in children in eastern and southern Africa. In India, farmers have grown a high-yielding sorghum variety with enhanced grain levels of iron and zinc since 2018 and use of iron-biofortified pearl millet has improved nutrition among vulnerable communities.

Thefuture
Crop breeders have been laying the groundwork to pursue genomic selection. This approach takes advantage of low-cost, genome-wide molecular markers to analyze large populations and allow scientists to predict the value of particular breeding lines and crosses to speed gains, especially for improving genetically complex traits.
Speed breeding uses artificially-extended daylength, controlled temperatures, genomic selection, data science, artificial intelligence tools and advanced technology for recording plant information â also called phenotyping â to make breeding faster and more efficient. A CIMMYT speed breeding facility for wheat features a screenhouse with specialized lighting, controlled temperatures and other special fixings that will allow four crop cycles â or generations â to be grown per year, in place of only two cycles with normal field trials. Speed breeding facilities will accelerate the development of productive and robust varieties by crop research programs worldwide.
Data analysis and management. Growing and evaluating hundreds of thousands of plants in diverse trials across multiple sites each season generates enormous volumes of data that breeders must examine, integrate, and co-analyze to inform decisions, especially about which lines to cross and which populations to discard or move forward. New informatics tools such as the Enterprise Breeding System will help scientists to manage, analyze and apply big data from genomics, field and lab studies.
Following the leaders. Driven by competition and the quest for profits, private companies that market seed and other farm products are generally on the cutting edge of breeding innovations. The CGIARâs Excellence in Breeding (EiB) initiative is helping crop breeding programs that serve farmers in low- and middle-income countries to adopt appropriate best practices from private companies, including molecular marker-based approaches, strategic mechanization, digitization and use of big data to drive decision making. Modern plant breeding begins by ensuring that the new varieties produced are in line with what farmers and consumers want and need.
India has conferred posthumously upon Sanjaya Rajaram, 2014 World Food Prize laureate and former wheat breeder and Director of the Wheat Program at the International Maize and Wheat Improvement Center (CIMMYT), its prestigious 2022 Padma Bhushan Award in “Science and Engineering” in recognition of “distinguished service of high order.”
Among the most successful crop breeders in history, Rajaram, who passed away in 2021, personally oversaw the development of nearly 500 high-yielding and disease-resistant wheat varieties that were grown on at least 58 million hectares in over 50 countries, increasing global wheat production by more than 200 million tons and especially benefiting hundreds of millions of the resource-poor whose diets and livelihoods depend on this critical crop. In India and the neighboring South Asian nations of Bangladesh, Nepal, and Pakistan, inhabitants consume more than 120 million tons of wheat and wheat-based foods each year.
âDr. Rajaram was a true titan of wheat breeding and an inspiration for young researchers, training and mentoring more than 700 scientists from developing countries worldwide,â said Bram Govaerts, CIMMYT director general. âHe was also a complete gentleman, comporting himself with modesty and grace despite his many honors and accomplishments; his first priority was helping and crediting others. Rajaram is an example today for all of us to keep working with the final stakeholder â the farmer â in mind.â
The rise from rural beginnings
Born on a small farm in District Varanasi, Uttar Pradesh, India, in 1943, Rajaram studied genetics and plant breeding at the Indian Agricultural Research Institute in New Delhi. After receiving his Ph.D. from the University of Sydney, he joined CIMMYT in 1969, working as a wheat breeder alongside Nobel Prize Laureate and CIMMYT scientist Norman Borlaug in Mexico. Recognizing his talent and initiative, Borlaug appointed Rajaram as head of CIMMYTâs wheat breeding program at just 29 years of age.
The Padma Bhushan Award was announced by President Ram Nath Kovind of India on the countryâs Republic Day, January 26. In 2015, Rajaram received the Pravasi Bharatiya Samman award, the highest honor conferred on Indians overseas. In 2001 he accepted the Padma Shri award from the government of India and, in 1998, the Friendship Award from the government of China.

Though a plant breeder and scientist by profession, Rajaram used the platform of his 2014 World Food Prize to promote an expansive, integrated vision for agricultural development. âIf we want to make a change, research wonât do it alone; we need to work directly with farmers and to train young agronomists, ensuring they have a broad vision to address the problems in farmersâ fields,â Rajaram said at a news conference in Mexico City in 2014.
Rajaram also served as Director of the Integrated Gene Management Program at the International Center for Agricultural Research in the Dry Areas (ICARDA) before formally retiring in 2008. In his retirement, he continued as a special scientific advisor to CIMMYT and ICARDA.
Longstanding partners pushing forward for farmers
“Indiaâs agricultural research community is proud of the distinguished achievements of Dr. Rajaram,” said Trilochan Mohapatra, Director General of the Indian Council of Agricultural Research (ICAR) and Secretary of the Department of Agricultural Research and Education (DARE), of India’s Ministry of Agriculture and Farmers’ Welfare. “ICAR greatly appreciates its valuable collaborations with CIMMYT to help farmers grow better crops and conserve resources under increasingly challenging conditions.”
The partnership of India with CIMMYT harks back to the 1960s-70s, when Indian farmers tripled national wheat yields in a few years by growing Borlaugâs high-yield wheat varieties and adopting improved farming practices.
In 2011, India and CIMMYT jointly launched the Borlaug Institute for South Asia (BISA) to improve cropping systems and food security, helping farmers to confront climate change and natural resource scarcities, among other challenges.
S. Ayyappan, former ICAR Director General who signed the joint declaration of intent for BISAâs establishment in India, has been honored with the 2022 Padma Shri Award.
CIMMYT is a non-profit international agricultural research and training organization focusing on two of the worldâs most important cereal grains, maize and wheat, and related cropping systems and livelihoods. Wheat varieties derived from CIMMYT and ICARDA research cover more than 100 million hectares â nearly two-thirds of the area sown to improved wheat worldwide â and bring benefits in added grain worth as much as $3.8 billion each year.
Genomic selection identifies individual plants based on the information from molecular markers, DNA signposts for genes of interest, that are distributed densely throughout the wheat genome. For wheat blast, the results can help predict which wheat lines hold promise as providers of blast resistance for future crosses and those that can be advanced to the next generation after selection.
In this study, scientists from the International Maize and Wheat Improvement Center (CIMMYT) and partners evaluated genomic selection by combining genotypic data with extensive and precise field data on wheat blast responses for three sets of genetically diverse wheat lines and varieties, more than 700 in all, grown by partners at locations in Bangladesh and Bolivia over several crop cycles.
The study also compared the use of a small number of molecular markers linked to the 2NS translocation, a chromosome segment from the grass species Aegilops ventricosa that was introduced into wheat in the 1980s and is a strong and stable source of blast resistance, with predictions using thousands of genome-wide markers. The outcome confirms that, in environments where wheat blast resistance is determined by the 2NS translocation, genotyping using one-to-few markers tagging the translocation is enough to predict the blast response of wheat lines.
Finally, the authors found that selection based on a few wheat blast-associated molecular markers retained 89% of lines that were also selected using field performance data, and discarded 92% of those that were discarded based on field performance data. Thus, both marker-assisted selection and genomic selection offer viable alternatives to the slower and more expensive field screening of many thousands of wheat lines in hot-spot locations for the disease, particularly at early stages of breeding, and can speed the development of blast-resistant wheat varieties.
The research was conducted by scientists from the International Maize and Wheat Improvement Center (CIMMYT), the Bangladesh Wheat and Maize Research Institute (BWMRI), the Instituto Nacional de InnovaciĂłn Agropecuaria y Forestal (INIAF) of Bolivia, the Borlaug Institute for South Asia (BISA) and the Indian Council of Agricultural Research (ICAR) in India, the Swedish University of Agricultural Sciences (Alnarp), and Kansas State University in the USA. Funding for the study was provided by the Bill & Melinda Gates Foundation, the Foreign and Commonwealth Development Office of the United Kingdom, the U.S. Agency for International Development (USAID), the CGIAR Research Program on Wheat (WHEAT), the Indian Council of Agricultural Research (ICAR), the Swedish Research Council, and the Australian Centre for International Agricultural Research (ACIAR).

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 worldâs 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)âs 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 âhidden enemyâ 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.

Indian agricultural researcher Pooja Bhatnagar-Mathur, a Principal Scientist at CIMMYT, says aflatoxin, a toxin produced from soil fungus and found in groundnuts like peanuts, is a serious public health and food safety problem around the globe.
Several recent studies document the long-term health and economic benefits from the âGreen Revolutionâ â the widespread adoption of high-yielding staple crop varieties during the last half of the 20th century â and argue for continued investment in the development and use of such varieties.
âOur estimates provide compelling evidence that the health benefits of broad-based increases in agricultural productivity should not be overlooked,â the authors state. âFrom a policy perspective, government subsidies for inputs leading to a green revolution as well as investments in extension and R&D programs seem to be important.â

The COVID-19 pandemic exposed the fragility of the global food system and the need to transform it, increasing its environmental and economic resilience to withstand future threats, and underpinning healthier diets. The studies suggest that improved versions of cereal crops such as rice, wheat, and maize can play a key role.
âOur work speaks to the importance of supporting innovation and technology adoption in agriculture as a means of fostering economic development, improved health, and poverty reduction, said author Jan von der Goltz. âIt also suggests that it is reasonable to view with some alarm the steady decline in funding for cereal crop improvement over the last few decades in sub-Saharan Africa, the continent with least diffusion of modern varieties.â
Likewise, a study co-authored by Prashant Bharadwaj of the University of California, San Diego, concluded that farmer adoption of high-yielding crop varieties (HYVs) in India reduced infant mortality dramatically across the country. Between 1960 and 2000, infant deaths dropped from 163.8 to 66.6 per 1,000 live births, and this occurred during the decades of Indiaâs wheat productivity leap from 0.86 to 2.79 tons per hectare, as a result of HYV adoption and improved farming practices.
âWhat both of these papers do is to carefully establish a causal estimate of how HYVs affect infant mortality, by only comparing children born in the same location at different points in time, when HYV use was different, and by checking that mortality before arrival of HYVs was trending similarly in places that would receive different amount of HYVs,â Bharadwaj said.
âIn the absence of a randomized control trial, these econometric techniques produce the best causal estimate of a phenomenon as important as the spread of HYVs during and after the Green Revolution,â he added. These thoughts were echoed by University of California San Diego professor Gordon McCord, a co-author of the global study.
Recent studies indicate that the Green Revolution also had long-term economic impacts, which also affected health outcomes.
In a 2021 update to the 2018 paper âTwo Blades of Grass: The Impact of the Green Revolution,â Douglas Gollin, Professor of Development Economics at Oxford University and co-authors found that, in 90 countries where high-yielding varieties were adopted between 1965 and 2010, food crop yields increased by 44% and that, had this adoption not occurred, GDP per capita in the developing world could be half of what it is today.
Even a 10-year delay of the Green Revolution would, in 2010, have cost 17% of GDP per capita in the developing world, with a cumulative GDP loss of $83 trillion, equivalent to one year of current global GDP.
These GDP and health impacts were boosted by a related reduction in population growth. By observing causal inference at country, regional and developing world levels, and using a novel long-term impact assessment method, the study authors detected a trend: as living standards improved for rural families, they generally wanted to invest more in their children and have fewer.
âOur estimates suggest that the world would have contained more than 200 million additional people in 2010, if the onset of the Green Revolution had been delayed for ten years,â Gollin and his co-authors stated. This lower population growth seems to have increased the relative size of the working age population, which furthered GDP growth.

A long-term investment in system transformation
It takes time from the point of an intervention to when broad health impacts can be observed in the population, the authors note. For example, although the development of modern high-yielding varieties began in the 1950s and 60s, the rate of adoption did not speed up until the 1980s, 1990s, and even into the 2000s, with evidence from sub-Saharan Africa showing that variety adoption has increased by as much in the 2000s as in the four preceding decades.
In addition, any nutrition and food security strategy which aims to reach the second Sustainable Development Goal of feeding 9 billion by 2050 must incorporate wider system transformation solutions, such as zero-emissions agriculture, affordable, diverse diets and increased land conservation.
As Gollin explained, âThe Green Revolution taught us that we need to approach productivity increases, especially in staple crop yields, differently. The challenge now is more complex: we need to get the same productivity increases, with fewer inputs and resources, more environmental awareness, and in larger quantities for more people.â
In part, this means increasing productivity on existing agricultural land with positive environmental and social impacts, according to Bram Govaerts, director general of the International Maize and Wheat Improvement Center (CIMMYT).
âBreeding and sharing more productive, hardy crop varieties is as important as ever,â Govaerts said, âbut also engaging farmers â in our case, smallholders â in shared research and innovation efforts to bridge yield gaps, build climate-resilient farming systems, and open access to better nutrition and market opportunities.â
