CIMMYT scientists have also made available a summary of key facts and figures about the impact of the Russia-Ukraine war on wheat supply (PowerPoint, 32MB): changing patterns of consumption and effect on food prices, geographic export supply concentration, global wheat imports, and specific vulnerabilities particularly in the Global South.
The Russia-Ukraine conflict will cause massive disruptions to global wheat supply and food security. Agricultural research investments are the basis of resilient agri-food systems and a food-secure future.
War highlights the fragility of the global food supply â sustained investment is needed to feed the world in a changing climate, Alison Bentley explains on Nature.
A new Bloomberg op-ed urges nations to steer more money to organizations like CIMMYT that are advancing crucial research on how to grow more resilient wheat and maize crops in regions that are becoming steadily less arable.
The war in Ukraine, coupled with weather-related disruptions in the worldâs major grain-producing regions, could unleash unbearable humanitarian consequences, civil unrest, and major financial losses worldwide, say Sharon E. Burke (Ecospherics) and Bram Govaerts (CIMMYT) on The Boston Globe.
The paper âEnlisting wild grass genes to combat nitrification in wheat farming: A nature-based solutionâ received the 2021 Cozzarelli Prize, which recognizes outstanding articles published in the journal Proceedings of the National Academy of Sciences of the United States of America (PNAS). The paper was published as a joint research collaboration of Japan International Research Center for Agricultural Sciences (JIRCAS), the International Maize and Wheat Improvement Center (CIMMYT), the University of the Basque Country (UPV/EHU) and Nihon University.
The study identifies of a chromosomal region that regulates the biological nitrification inhibition (BNI) ability of wheat grass (Leymus racemosus), a wild relative of wheat. It also outlines the development of the world’s first BNI-enhanced wheat, through intergeneric crossing with a high-yielding wheat cultivar.
This research result is expected to contribute to the prevention of nitrogen pollution that leads to water pollution and greenhouse gas emissions, reducing the use of nitrogen fertilizer while maintaining productivity.

How does CIMMYTâs improved maize get to the farmer?
CIMMYT is proud to announce a new, improved highland maize hybrid that is now available for uptake by public- and private-sector partners, especially those interested in marketing or disseminating hybrid maize seed across upper altitudes of Eastern Africa and similar agro-ecologies. National agricultural research system (NARS) and seed companies are hereby invited to apply for licenses to pursue national release, scale-up seed production, and deliver these maize hybrids to farming communities.
The deadline to submit applications to be considered during the first round of allocations is 8 April 2022. Applications received after that deadline will be considered during subsequent rounds of product allocations.
The newly available CIMMYT maize hybrid, CIM20EAPP3-01-47, was identified through rigorous trialing and a stage-gate advancement process that culminated in the 2021 Eastern Africa Regional On-Farm Trials for CIMMYTâs eastern Africa highland maize breeding pipeline (EA-PP3). While individual products will vary, the EA-PP3 pipeline aims to develop maize hybrids fitting the product profile described in the following table:

A new $25.7 million project, led by the International Maize and Wheat Improvement Center (CIMMYT), a Research Center part of CGIAR, the worldâs largest public sector agriculture research partnership, is expanding the use of biodiversity held in the worldâs genebanks to develop new climate-smart crop varieties for millions of small-scale farmers worldwide.
As climate change accelerates, agriculture will be increasingly affected by high temperatures, erratic rainfall, drought, flooding and sea-level rise. Looking to the trove of genetic material in genebanks, scientists believe they can enhance the resilience of food production by incorporating this diversity into new crop varieties â overcoming many of the barriers to fighting malnutrition and hunger around the world.
“Better crops can help small-scale farmers produce more food despite the challenges of climate change. Drought-resistant staple crops, such as maize and wheat, that ensure food amid water scarcity, and faster-growing, early-maturing varieties that produce good harvests in erratic growing seasons can make a world of difference for those who depend on agriculture. This is the potential for climate-adaptive breeding that lies untapped in CGIARâs genebanks,” said Claudia Sadoff, Managing Director, Research Delivery and Impact, and Executive Management Team Convener, CGIAR.
Over five years, the project, supported by the Bill & Melinda Gates Foundation, aims to identify plant accessions in genebanks that contain alleles, or gene variations, responsible for characteristics such as heat, drought or salt tolerance, and to facilitate their use in breeding climate-resilient crop varieties. Entitled Mining useful alleles for climate change adaptation from CGIAR genebanks, the project will enable breeders to more effectively and efficiently use genebank materials to develop climate-smart versions of important food crops, including cassava, maize, sorghum, cowpea and rice.

The project is a key component of a broader initiative focused on increasing the value and use of CGIAR genebanks for climate resilience. It is one of a series of Innovation Sprints coordinated by the Agriculture Innovation Mission for Climate (AIM4C) initiative, which is led by the United Arab Emirates and the United States.
âBreeding new resilient crop varieties quickly, economically and with greater precision will be critical to ensure small-scale farmers can adapt to climate change,â said Enock Chikava, interim Director of Agricultural Development at the Bill & Melinda Gates Foundation. âThis initiative will contribute to a more promising and sustainable future for the hundreds of millions of Africans who depend on farming to support their families.â
Over the past 40 years, CGIAR Centers have built up the largest and most frequently accessed network of genebanks in the world. The network conserves and makes nearly three-quarters of a million crop accessions available to scientists and governments. CGIAR genebanks hold around 10% of the worldâs plant germplasm in trust for humanity, but account for about 94% of the germplasm distributed under the International Treaty on Plant Genetic Resources for Food and Agriculture, which ensures crop breeders globally have access to the fundamental building blocks of new varieties.
âThis research to develop climate-smart crop varieties, when scaled, is key to ensuring that those hardest hit by climate shocks have access to affordable staple foods,â said Jeffrey Rosichan, Director of the Crops of the Future Collaborative of the Foundation for Food & Agriculture Research (FFAR). âFurther, this initiative benefits US and world agriculture by increasing genetic diversity and providing tools for growers to more rapidly adapt to climate change.â
âWe will implement, for the first time, a scalable strategy to identify valuable variations hidden in our genebanks, and through breeding, deploy these to farmers who urgently need solutions to address the threat of climate change,â said Sarah Hearne, CIMMYT principal scientist and leader of the project.
Building on ten years of support to CIMMYT from the Mexican government, CGIAR Trust Fund contributors and the United Kingdomâs Biotechnology and Biological Sciences Research Council (BBSRC), the project combines the use of cutting-edge technologies and approaches, high-performance computing, GIS mapping, and new plant breeding methods, to identify and use accessions with high value for climate-adaptive breeding of varieties needed by farmers and consumers.

In the traditional Indian society Madhulika Singh grew up in, girls choosing to study science, technology, engineering or mathematics (STEM) was as radical as choosing a life partner on their own.
“They say women hold up half the sky. I believe they should hold up as much and contribute equally in STEM too,” says Singh, now an agriculture specialist at the International Maize and Wheat Improvement Center (CIMMYT).
In her early teens she saw her mother, a school headmaster, comfortably navigate her career along with her domestic responsibilities without a sweat. She later saw a similar example in her sister-in-law. “I grew up thinking âthere is so much that a woman is capable of,â whether at home or her workplace,” Singh recalls.
This strong idea of women’s potential led her to pursue studies in science. “Many women before me, like my mother’s generation, were encouraged to take up [careers in] humanities â become a teacher, or pursue home management courses â to ensure a smooth transition once married,” Singh explains. She hoped this would change during her time and that following a career in STEM would be a matter of choice â not gender.
Singhâs goals and ambitions were very clear from the very beginning. In school, she was interested in biology, particularly plant studies and botany. Her inquisitive nature was reflected in her projects and presentations, scoring her high grades. She demonstrated a thorough understanding of plant physiology and her passion for the subject. The budding scientist always wanted to know more and to do more, which Singh feels resonates with her current research and publications.
A popular quote attributed to Mahatma Gandhi says âBe the change you want to see in the world.â When Singh chose to take up plant science in graduate school and then agriculture science for her doctorate, she became the change she had hoped to see in her home and society as a young girl. With the support from her family but a skeptical society, she went ahead and pursued a career in STEM, beginning her research on maize genotypes and conservation agriculture. In 2013 she joined CIMMYT as a physiologist.

Helping farmers transition to conservation agriculture
Singh currently works in her home state of Bihar for the Cereal Systems Initiative for South Asia (CSISA), led by CIMMYT. She is engaged with over ten thousand farmers from the states of Bihar and Uttar Pradesh, supporting the adoption of  conservation agriculture practices.
Farming is vital for the region, as nearly 70% of the population is engaged in agriculture and extension services. However, food and livelihoods are threatened by the small size of farms, low incomes, and comparatively low levels of agricultural mechanization, irrigation and productivity.
Singh and her colleagues have led the transition from traditional farming to sustainable intensification practices â like early wheat sowing, zero tillage and direct-seeded rice â which have helped smallholder farmers increase their yield potential substantially.
“We believe a project like CSISA, along with the government and partners, can help advance and support in realizing the full agriculture potential of these regions,” Singh explains.
Roots in the soil
Her grandparents were farmers. “To be able to care for the land that provided you nourishment and a living was always admired upon,” she says. As a crop scientist, Singh’s family acknowledges her work as an extension of the services her grandparents practiced.
Sustained by this motivation and encouragement, Singh feels reassured of her role: joining other scientists, partners and farmers to make agriculture sustainable and our communities food-secure.
âThe fact that the data we generate from our experiments serve as building blocks in the generation of knowledge and help farmers optimize the cost of inputs and increase their productivity is fulfilling and enriching to me,” Singh expresses.
Apart from working to build the capacity of farmers and extension workers, Singh supports the implementation of field trials and community-based technology demonstrations. She also helps refine key agricultural innovations, through participatory testing, and optimizes cropping systems in the region.
Leading the way for for the next generation
A true representative of the STEM community, Singh is always learning and using her experience to give back to society. She has co-authored numerous books and contributed to journals, sharing her knowledge with others.
Other women leaders in STEM have inspired Singh in her professional life, including CIMMYTâs former deputy director general for research Marianne Banziger. Singh believes Banziger was trailblazing and that young girls today have many female role models in STEM that can serve as inspiration.
The change is already here and many more young women work in STEM, pursuing excellence in agriculture sciences, engineering and research studies contributing to as well as claiming âhalf the sky.”

Over the course of ten years, WHEAT worked with hundreds of research and development partners worldwide to release high-yielding, disease-resistant, nutritious and climate-resilient wheat varieties, and efficient, sustainable wheat-based cropping systems.
This final report from 2021 shares important research on staple cerealsâ role in global efforts towards food security, the number and distribution of wheat farms, the expected impact of climate change on wheat productivity, nitrogen-in-agriculture research, nutrition, and the most critical, immediate effects of COVID-19 on food systems, and more.
With its national partners, WHEAT released 70 new CGIAR-derived wheat varieties to farmers in 13 countries in 2021, and developed 18 innovations in the areas of genetics, biophysics, farm management, research and communication methods, or social sciences.
Over the past several decades, maize breeders have made considerable strides in the development and deployment of new hybrids. These offer higher yields compared to older varieties and reduce the risks farmers face from the vagaries of a changing climate and emerging pest and disease threats. But, for small-scale farmers to adopt new, improved climate-resilient and stress-tolerant maize hybrids at scale, they must be first available, accessible and their benefits need to be widely understood and appreciated. This is where vibrant national seed industries potentially play an important role.
Prior to the 1990s, government agencies tended to play the lead role in hybrid production and distribution. Since then, expectations are that the private sector â in particular locally owned small-scale seed enterprises â produce maize hybrids and distribute them to farmers. When successful, local seed industries are able to produce quality new hybrids and effectively market them to farmers, such that newer hybrids replace older ones in agrodealer stores in relatively short periods of time. If small seed enterprises lack capacities or incentives to aggressively market new hybrids, then the gains made by breeding will not be realized in farmersâ fields. By monitoring seed sales, breeders at CIMMYT and elsewhere, as well as seed business owners, gain insights into smallholdersâ preferences and demands.
A recent publication in Food Security assesses the capacities of 22 small and medium-sized seed enterprises in Mexico to produce and market new maize hybrids. The study draws on the experience of the MasAgro project, a decade-long development whereby the International Maize and Wheat Improvement Center (CIMMYT), in partnership with Mexicoâs Department of Agriculture and Rural Development (SADER), engaged with dozens of locally owned seed businesses to expand their portfolio of maize hybrids.
The authors, led by CIMMYT senior economist Jason Donovan, highlight the critical role the MasAgro project played in reinvigorating the portfolios of maize seeds produced by small and medium-sized enterprises. MasAgro âfilled a gap that had long existed in publicly supported breeding programsâ by providing easy access to new cultivars, available to local seed companies without royalties or branding conditions, and without the need for seed certification. The enterprises, in turn, showed a remarkably high capacity to take up new seed technology, launching 129 commercial products between 2013 and 2017.
âWithout doubt the MasAgro project can be considered a success in terms of its ability to get new maize germplasm into the product portfolios of small seed companies throughout Mexico,â Donovan said.
The authors also delve into the challenges these maize enterprises faced as they looked to scale the new technologies in a competitive market that has long been dominated by multinational seed enterprises. They observed a lack of access to physical capital, which in turn evidenced a lack of financial capital or access to credit, as well as limited marketing know-how and capacity to integrate marketing innovations into their operations. While most maize enterprises identified the need to expand sales of new commercial products, âsigns of innovation in seed marketing were limitedâ and most of them relied heavily on sales to local and state governments.
According to Donovan, âThe MasAgro experience also shows that a strong focus on the demand side of formal seed systems is needed if breeding programs are to achieve greater impact in less time. This implies more attention to how farmers decide on which seed to purchase and how seed companies and seed retailers market seed to farmers. It also implies strong coordination between public sector to make building the local seed industry a national imperative.â
Beyond the Mexican context, the paperâs findings may be of particular interest to development organizations looking to supply local seed industries facing strong competition from regional and multinational companies. One example is the effort to support small seed businesses in Nepal, which face strong competition from larger Indian companies with long histories of engagement in Nepalese seed markets. There are also important lessons for policymakers in eastern and southern Africa, where strict controls over seed release and certification potentially lead to higher production costs and slower rates of introduction of new products by local maize seed companies.
This international Womenâs Day, March 8, 2022, the International Maize and Wheat Improvement Center (CIMMYT) celebrates the essential role that women play in agriculture and food systems, and acknowledges that gender equality is essential to achieve a sustainable future. The burden of climate change impacts women disproportionately, even though we rely on them to drive change in climate adaptation, mitigation and solutions.
For example, in the last year, CIMMYT research found that educating women farming wheat in Bihar, India, increases the adoption of climate-smart agricultural practices, which, in turn, reduces greenhouse gas emissions, and boosts nitrogen productivity, eco-efficiency and yield. Additionally, in Mexico, a CIMMYT study found that women are less likely to default on agricultural credit than men, but seldom receive loans. Connecting women to financial capital to obtain agricultural inputs is an essential step in boosting their decision-making in food production.

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.

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.
