CIMMYT has several offices in the Americas, including global headquarters in Mexico and a regional office in Colombia. Activities are supported by an additional 140 hectares of stations in diverse agro-ecological zones of Mexico. CIMMYTâs genebank in Mexico stores 27,000 maize and 170,000 wheat seed collections â key to preserving the crop genetic diversity of the region. CIMMYT projects range from developing nutritionally enhanced maize to mapping regional climate change hot spots in Central America. The comprehensive MasAgro project aims to increase wheat production in Mexico by 9 million tons and maize production by 350,000 tons by 2030. CIMMYT promotes regional collaboration and facilitates capacity building for scientists, researchers and technicians.

A new partnership announced today between the International Maize and Wheat Improvement Center (CIMMYT), PepsiCo and Grupo Trimex will greatly contribute to scale out sustainable farming practices in the central Mexican states of Guanajuato and MichoacĂĄn, which together form the countryâs second wheat producing region.
The project Agriba Sustentable â a shortened reference for BajĂo Sustainable Agriculture â will promote the adoption of conservation agriculture-based sustainable intensification practices among local farmers who will have access to PepsiCoâs wheat grain supply chain via Grupo Trimex.
âA part of the wheat that we use in Mexico for our products comes from the BajĂo region,â said Luis Treviño, Director of Sustainability at PepsiCo Latin America. âHowever, agricultural production in the region has needs and areas of opportunity that we were able to identify thanks to the experience and deep knowledge that CIMMYT has developed over the years.â
Agriba Sustentable is the latest example of the new business models that CIMMYT is exploring as part of its integrated development approach to agri-food systems transformation, which seeks to engage multiple public, private and civil sector collaborators in cereals value chain development and enhancement efforts.
âThe projectâs specific goal is to improve the sustainability of the wheat production system in the BajĂo region by enabling the adoption of technological innovations and sustainable production practices among at least 200 farmers in the Grupo Trimex supply chain during the first year of implementation, and to gradually scale out to reach many more farmers,â said Bram Govaerts, Director General of CIMMYT.
CIMMYTâs long-term field trials in Mexico have shown that conservation agriculture-based sustainable intensification practices raise wheat yields by up to 15% and cut greenhouse gas emissions by up to 40%.
âThe farming practices that CIMMYT promotes reduce environmental impact,â said Mario Ruiz, Sourcing Manager of Grupo Trimex. âConservation agriculture can cut CO2 emissions by up to 60% from reduced diesel consumption, lower fuel use by up to 70% and water consumption by 30%.â
According to PepsiCo Mexico, Agriba Sustentable is an important step for its global vision PepsiCo Positive (pep+), which seeks to offset its agricultural footprint by promoting sustainable farming on 2.8 million hectares globally. The plan also aims to improve the livelihoods of 250,000 people who are part of their global agricultural supply chain and to source sustainably 100% of the companyâs key ingredients by 2030.

Have you ever considered that bread and pasta are made from different types of wheat? How about the fact that there are thousands of different wheat products consumed around the world, and each one has unique characteristics and processing requirements?
Scientists at the International Maize and Wheat Improvement Center (CIMMYT) understand that the quality of the final product, be it spaghetti, a loaf of sourdough bread or a tandoori naan, is highly dependent on the quality of the grain and the flour it becomes. Every year, CIMMYT analyzes thousands of wheat lines in detail at its Wheat Quality laboratory to determine the nutritional, processing and end-use quality of the grain. In this short video, CIMMYTâs Wheat Quality lab head Maria Itria Ibba explains exactly what they are looking for and how they find it.
First, CIMMYT scientists test the overall grain quality by analyzing grain weight, density, protein content, moisture content and hardness.
The grains are then milled into flour, which is again analyzed for moisture content, protein content, color and protein quality. Protein quality is especially important to determine the end-use for the type of flour, and CIMMYT conducts several tests to determine this characteristic. Bread and durum wheat flours specifically are analyzed for overall protein quality by checking SDS-sedimentation volume. Mixographs are used to assess the flourâs mixing and absorption characteristics, and alveographs are used to measure dough deformation properties.
At the end of the tests, bread wheat flours are transformed into leavened breads and scored based on the loafâs volume and crumb quality. Durum wheat flour, used to make Italian-style pasta, is scored based on grain quality, flour yellowness, high protein content and protein quality.
CIMMYTâs work ensures that wheat-derived foods produced in developing countries are nutritious, affordable, and maximize profits for each actor in the value chain.

Ridderâs smart technology is used by CIMMYT scientists to develop wheat and maize varieties that boost production, prevent crop disease and improve smallholder farmersâ livelihood.
The International Maize and Wheat Improvement Center (CIMMYT) is offering a new set of elite, improved maize hybrids to partners for commercialization in the tropical lowlands of Latin America and similar agro-ecological zones. National agricultural research systems (NARS) and seed companies are invited to apply for licenses to commercialize these new hybrids, in order to bring the benefits of the improved seed to farming communities. In some countries, depending on the applicable regulatory framework for commercial maize seed, successful applicants may first need to sponsor the products through the national registration / release process prior to commercialization.
The deadline to submit applications to be considered during the first round of allocations is September17, 2021. Applications received after that deadline will be considered during the following round of product allocations.
Information about the newly available CIMMYT maize hybrids from the Latin America breeding program, application instructions and other relevant material is available in the CIMMYT Maize Product Catalog and in the links provided below.
Applications must be accompanied by a proposed commercialization plan for each product being requested. Applications may be submitted online via the CIMMYT Maize Licensing Portal in English or Spanish.
Alternatively, applications may be submitted via email to GMP-CIMMYT@cgiar.org using the PDF forms available for download at the links below. Each applicant will need to complete one copy of Form A for their organization, then for each hybrid being requested a separate copy of Form B. (Please be sure to use these current versions of the application forms.)

Every year, the spores of the wheat blast fungus lie in wait on farms in South America, Bangladesh, and beyond. In most years, the pathogen has only a small impact on the countriesâ wheat crops. But the disease spreads quickly, and when the conditions are right thereâs a risk of a large outbreak â which can pose a serious threat to the food security and livelihood of farmers in a specific year.
To minimize this risk, an international partnership of researchers and organizations have created the wheat blast Early Warning System (EWS), a digital platform that notifies farmers and officials when weather conditions are ideal for the fungus to spread. The team, which began its work in Bangladesh, is now introducing the technology to Brazil â the country where wheat blast was originally discovered in 1985.
The International Maize and Wheat Improvement Center (CIMMYT), the Brazilian Agricultural Research Corporation (EMBRAPA), Â Brazilâs University of Passo Fundo (UPF) and others developed the tool with support from USAID under the Cereal Systems Initiative for South Asia (CSISA) project.
Although first developed with the help of Brazilian scientists for Bangladesh, the EWS has now come full circle and is endorsed and being used by agriculture workers in Brazil. The team hopes that the system will give farmers time to take preventative measures against the disease.
Outbreaks can massively reduce crop yields, if no preventative actions are taken.
âIt can be very severe. It can cause a lot of damage,â says MaurĂcio Fernandes, a plant epidemiologist with EMBRAPA.
Striking first
In order to expand into a full outbreak, wheat blast requires specific temperature and humidity conditions. So, Fernandes and his team developed a digital platform that runs weather data through an algorithm to determine the times and places in which outbreaks are likely to occur.
If the system sees a region is going to grow hot and humid enough for the fungus to thrive, it sends an automated message to the agriculture workers in the area. These messages â texts or emails â alert them to take preemptive measures against the disease.
More than 6,000 extension agents in Bangladesh have already signed up for disease early warnings.
In Brazil, Fernandes and his peers are connecting with farmer cooperatives. These groups, which count a majority of Brazilian farmers as members, can send weather data to help inform the EWS, and can spread alerts through their websites or in-house applications.
Wheat blast can attack a plant quickly, shriveling and deforming the grain in less than a week from the first symptoms. Advance warnings are essential to mitigate losses. The alerts sent out will recommend that farmers apply fungicide, which only works when applied before infection.
âIf the pathogen has already affected the plant, the fungicides will have no effect,â Fernandes says.
A blast from the past
Because wheat had not previously been exposed to Magnaporthe oryzae, most wheat cultivars at the time had no natural resistance to Magnaporthe oryzae, according to Fernandes.  Some newer varieties are moderately resistant to the disease, but the availability of sufficient seed for farmers remains limited.
The pathogen can spread through leftover infected seeds and crop residue. But its spores can also travel vast distances through the air.
If the fungus spreads and infects enough plants, it can wreak havoc over large areas. In the 1990s â shortly after its discovery â wheat blast impacted around three million hectares of wheat in South America. Back in 2016, the disease appeared in Bangladesh and South Asia for the first time, and the resulting outbreak covered around 15,000 hectares of land. CGIAR estimates that the disease has the potential to reduce the regionâs wheat production by 85 million tons.
In Brazil, wheat blast outbreaks can have a marked impact on the countryâs agricultural output. During a major outbreak in 2009, the disease affected as many as three million hectares of crops in South America. As such, the EWS is an invaluable tool to support food security and farmer livelihoods. Fernandes notes that affected regions can go multiple years between large outbreaks, but the threat remains.
âPeople forget about the disease, then you have an outbreak again,â he says.
Essential partnerships
The EWS has its roots in Brazil. In 2017 Fernandes and his peers published a piece of research proposing the model. After that, Tim Krupnik, a senior scientist and country representative with CIMMYT in Bangladesh, along with a group of researchers and organizations, launched a pilot project in Bangladesh.
There, agriculture extension officers received an automated email or text message when weather conditions were ideal for wheat blast to thrive and spread. The team used this proof of concept to bring it back to Brazil.
According to Krupnik, the Brazil platform is something of a âhomecomingâ for this work. He also notes that cooperation between the researchers, organizations and agriculture workers in Brazil and Bangladesh was instrumental in creating the system.
âFrom this, we’re able to have a partnership that I think will have a significant outcome in Brazil, from a relatively small investment in research supplied in Bangladesh. That shows you the power of partnerships and how solutions can be found to pressing agricultural problems through collaborative science, across continents,â he says.

Tan spot disease, caused by the fungus Pyrenophora tritici-repentis, may be less well-known than other pathogens of wheat such as rust and blast, but its potential to become a major threat to wheat-growing regions worldwide is a serious concern.
In Kazakhstan, one of the main wheat growing nations in Central Asia, farmers have struggled with tan spot epidemics since the 1980s. During epidemic years, Kazakh farmers have reported losing nearly half of their harvest to the disease.
A recent study published in Frontiers in Genetics has unlocked a promising new weapon against tan spot disease. Scientists at the Institute of Plant Biology and Biotechnology (IPBB) in Kazakhstan and the International Maize and Wheat Improvement Center (CIMMYT) conducted a genome-wide association study (GWAS) which found new sources of genetic resistance to tan spot disease.
âBread wheat is the most important crop in Central Asia directly linked to food security. 45-60% of daily calories come from wheat,â said Alma Kokhmetova, Professor and Head of the Genetics and Breeding Laboratory at IPBB, who partnered with CIMMYT on this project.

Creative approaches to challenging, global issues
Global agriculture is repeatedly tested and threatened by emerging pests and diseases.
Fungicides and pesticides are not a one-stop, sustainable solution to controlling outbreaks. In addition to being unaffordable to much of the worldâs smallholder population, they have also been found to have some negative environmental and health side effects. But crop breeders will argue that there is a more efficient path to resilience: through genetics.
For example, some wheat varieties are naturally resistant to diseases such as tan spot â it is in their DNA. If breeders can figure out what genes hold the code to tan spot disease resistance, in this case, they can cross and breed future varieties to be naturally immune to the disease. It is a much cleaner, cheaper and greener solution than dousing the worldâs crops in fungus- and bug-killing chemicals.
A figure from the genome-wide association study shows novel genomic associations â especially here on chromosome 6A â that display resistance to both races of the tan spot fungus. (Figure: CIMMYT and IPBB)
Finding the needle in the haystack
Working together, CIMMYT and IPBB were able to find some important and novel genetic associations with resistance to tan spot for the two main races of the disease, race 1 and race 5, which are the most prevalent in Kazakhstan. The research centers assembled a panel with 191 samples of wheat having different levels of resistance from Kazakhstan, Russia and CIMMYT, through the International Winter Wheat Yield Partnership (IWWYP).
In order to conduct the genome-wide association study, the scientists used a genotyping platform called DArTseq to sequence the entries in the panel, a device that CIMMYT houses in its global headquarters in Mexico. The DArTseq method sequences the genome representations on the Next Generation Sequencing platforms and generates high-density single nucleotide polymorphisms (SNPs) data in a cost-effective manner.
Using the SNPs generated by DArTSeq and the phenotypic scoring of resistance to tan spot at the seedling and adult plant stages in Kazakhstan, the scientists were able to mark genomic regions associated with resistance to the disease. Novel regions on chromosomes 3BS, 5DL and 6AL were all found to have some promising traits of resistance, especially 6AL, which appears to be superior in protecting plants from both of the races of the pathogen.

The next steps
This discovery of a new source of genetic resistance to tan spot is exciting to breeders, researchers, donors, national agricultural systems, seed companies and, ultimately, farmers both in and outside of Kazakhstan. Essentially, any country that struggles with race 1 and race 5 of tan spot disease will benefit from this discovery.
âFor breeding purposes, 25 lines with the best allele combinations of novel and known genes identified in this study are currently being used in different crossing programs in Kazakhstan,â said Deepmala Sehgal, CIMMYT wheat geneticist. The next stage of this project will also be a collaborative effort with CIMMYT, where the results will be validated in other in genetic backgrounds.
âOnce the results are validated, their sequence information will be updated in a genotyping platform called Intertek, which has been designed to assist breeders in genotyping their germplasm with gene-based markers,â added Sehgal
More impact together
âThanks to the exchange of wheat materials between CIMMYT, Turkey and ICARDA (IWWIP), we have selected and produced disease-resistant advanced wheat lines. These wheat entries now are being evaluated in the different stages of the breeding process,â said Kokhmetova.
The early success of this study and partnership between CIMMYT and IPBB has led to another round of funding approved by the Kazakhstan government to bring this research to the next stage. Additionally, more projects that seek to find sources of genetic resistance to leaf rust and yellow rusts have recently been approved.
âDue to this previous successful collaboration done between IPBB and CIMMYT, two more projects have been funded to our national agricultural research system partner Professor Alma,â said Sehgal.
Although the story of tan spot-resistant wheat is still unfolding, major strides will continue to follow in the footsteps of this exceptional discovery.

The International Maize and Wheat Improvement Center (CIMMYT) is contributing to make Mexicoâs agriculture more productive, sustainable and resilient, according to a new report by The Economist Intelligence Unit and Barilla Foundation.
The study focuses on food loss and waste, sustainable agriculture, and nutritional challenges to assess how sustainable and resilient are the food systems of the 20 largest and most advanced economies of the world, which could lead the way to achieve the United Nationâs Sustainable Development Goals (SDGs) by 2030.
The authors discuss the intricacies between national food systems and progress towards SDGs as a cross-cutting issue: âThe challenge for the agricultural sectors in the G20 countries is to make their production processes more efficient so that they are growing sufficient food for their populations and their exporters, but doing so in a way that is decoupled from resource use, repairs the damage that has already been done to the planet, helps to raise nutritional standards, and in the wake of the pandemic, rebuilds our resilience to the emergence of diseases.â
Against this backdrop, the data systems of CIMMYTâs MasAgro project are identified as an innovation or best practice that helps cut agricultureâs carbon footprint in Mexico. Under Masagro, CIMMYT monitors over 150,000 farmers and more than 500 variables of the growing cycle per farming plot.
âFarmers can then access data analysis via an app which provides them with a range of information to help them improve productivity, use more sustainable practices and access markets,â the report states.

The authors conclude that G20 leaders still have a narrow opportunity to adopt a systems approach to reducing food loss and waste, mitigating the impact of food production on the environment, and increasing the nutritional content of global diets to achieve the SDGs by 2030.
However, the policy responses needed to trigger a transformational change in global food systems require political will and leadership. âInvolving different stakeholders in improving the sustainability of agriculture is key, according to Bram Govaerts of the International Maize and Wheat Improvement Center (CIMMYT),â reads the report.
The Board of Trustees appointed Bram Govaerts, renowned for pioneering, implementing and inspiring transformational changes for farmers and consumers in meeting sustainable development challenges, as Director General of CIMMYT.
An article in La NaciĂłn praises the work of a number of research institutions, including CIMMYT, for their use of science and technology to develop hybrid maize lines adapted to the needs of farmers, markets and consumers.
Women represent approximately 43 percent of the worldâs agricultural labor. Despite making up less than half of the labor force, women account for 60 to 80 percent of food production in developing countries. Often, official statistics ignore unpaid work â whether in the field, at a home garden or preparing food in the household â thus misrepresenting womenâs real contribution to agricultural work and production.
According to the United Nations Food and Agriculture Organization (FAO), if the worldâs women farmers had the same access to resources and agricultural financing as men, 150 million people could be lifted out of poverty.
There is no way that we will be able to reach zero hunger if the public and private sectors do not get involved in gender-sensitive programming that addresses womenâs access to finance and other resources and opportunities.
A new study supported by the Walmart Foundation, which has been working steadily on this issue, found that smallholder farmers in Mexico must overcome considerable obstacles to access financing â but the barriers to credit are significantly higher for women.
The International Maize and Wheat Improvement Center (CIMMYT) has conducted interventions in the field to support this finding. A multidisciplinary CIMMYT team offered advice on financial inclusion to a group of 1,425 farmers in southern Mexico from 2018 to 2020. The team found that while 331 men received credit, only six women of the same target group did.
Similarly, only three women were able to take out agricultural insurance and 29 opened a savings account after two years of intervention, compared to 110 and 171 men, respectively.
However, there is some hope: an increasing number of farmers, both women and men, is progressively acquiring the basic information and skills to formally request financial products.
CIMMYT obtained funding from the Walmart Foundation in 2018 to implement a project aimed at improving smallholder farmersâ access to markets through collective action, crop diversification, and enhanced access to finance in Mexicoâs southern states of Campeche, Chiapas and Oaxaca. The projectâs solid results in validation and adoption of sustainable and inclusive technologies were key factors enabling the continuation of activities through 2021.
According to VĂctor LĂłpez, senior manager of partnerships for access to markets at CIMMYT, women farmers are less likely than men to default on loans but seldom have the necessary collateral to be considered as potential clients by standard financial institutions. Without this financial support, they are unable to obtain land, insurance or other critical agricultural inputs, trapping them in a cycle of poverty.
CIMMYT and its partners are working toward a more inclusive approach. With the support of the Walmart Foundation, CIMMYT is strengthening the capacity of farmers â particularly smallholders â and farmer organizations to mitigate production risks and incorporate market-sound considerations into their cropping plans.
These and similar rural development ventures with an inclusive business model perspective can help smallholder farmers, particularly women, combat hunger and food insecurity in Mexico and beyond.
The challenge is to bridge the financial services divide between agriculture and almost every other sector. As economic activity resumes and Mexico gradually recovers from the pandemic crisis, we have a big opportunity to create new credit products and financial services for women farmers that prioritize innovation and sustainable production over ownership rights.
This op-ed by CIMMYT Director General Martin Kropff was originally published in the Mexican Business Review.
A multi-disciplinary team of agricultural researchers and development practitioners is proposing a new approach to tackle the shortcomings of global food production systems that degrade the environment, greatly contribute to climate change and fail to deliver healthy diets for a growing population.
The new methodology developed by the International Maize and Wheat Improvement Center (CIMMYT) in collaboration with the Alliance of Bioversity International and the International Center for Tropical Agriculture (CIAT) aims to transform national food systems by achieving consensus between multiple stakeholders and building on successful participatory agricultural research experiences.
According to a peer-reviewed paper published today in the journal PLOS ONE, the Integrated Agri-food System Initiative (IASI) âis designed to generate strategies, actions, and quantitative, [Sustainable Development Goals] SDGs-aligned targets that have [a significant] likelihood of supportive public and private investmentâ.
The IASI methodology is based on successful integrated development projects implemented by CIMMYT in Mexico and Colombia, the latter in partnership with the Alliance Bioversity-CIAT, which engaged multiple public, private and civil sector collaborators in local maize systems enhancement. These initiatives took advantage of sociopolitical âwindows of opportunityâ that helped build multiple stakeholder consensus around health, nutrition, food security and development aspirations in both countries.
âCIMMYTâs integrated development approach to maize systems transformation in Mexico and Colombia laid the foundations of the IASI methodology by overcoming government transitions, annual budget constraints and win-or-lose rivalry between stakeholders in favor of equity, profitability, resilience and sustainability,â said Bram Govaerts, chief operating officer and Integrated Development Program director at CIMMYT.
Ultimately, the IASI methodology offers public officials and development practitioners the possibility to transform food systems by scaling out innovative farming practices and technologies that lead to sustainably managed natural resources and improved nutrition and food security.
The main steps to implement the IASI methodology are:
Diverse experts examine the current status and the business-as-usual scenario based on analysis of the socioeconomic, political, and sectoral context and model-based projections;
Stakeholders determine a preferred future scenario based on assessment of national implications, and define drivers of change toward a desired scenario;
Defined criteria are applied to stakeholder and expert inputs to validate drivers of change and to identify strategies and actions â for example, public policies, value chain and market interventions, and biotechnology applications â that can steer toward the preferred future scenario, which are then reviewed and prioritized by high-level decision makers;
Stakeholders agree on measurable targets and tangible, time-bound actions toward the preferred future scenario;
Stakeholders build shared commitment to a tactical implementation plan among traditional, non-traditional, and new partners;
Ongoing stakeholder engagement is organized around an online dashboard that tracks actions and progress toward targets and supports course correction and coordinated investment.
Following these steps, the authors of the IASI methodology propose to build a âglobal food systems transformation networkâ to co-design and co-implement agricultural development projects that bring together multiple partners and donors for global agricultural systems transformation.
As the approach is refined and further applications are built, it is expected that this network will harness efforts to initiate a new field of research and global practice on âintegrated methodologies for food system transformation and innovationâ â analogous to the fields of business administration and organizational development.
IASI serves as the backbone of new CGIAR Regional Integrated Initiatives, which draw on capacities from regional international agricultural research centers and programs to deliver global agri-food system transformation.
It was clear to Fatima Camarillo Castillo from a young age that her future was in agriculture. She grew up on a farm in a small village in Zacatecas, Mexico, and recalls working in the fields alongside her father and siblings, helping with the harvests and milking the cows. And every year, her family ran into the same issue with their crops: droughts.
“Sometimes the harvest was okay, but sometimes we didnât have any harvest at all,” says Camarillo. “For us that meant that, if we didnât have enough harvest, then for the whole year my mother and father struggled to send us to school.”
But they did send her to school, and instead of escaping the persistent challenges that agriculture had presented her family in her young life, she was determined to solve them. “After elementary school we had to leave the farm to continue our education,” she explains. “I knew about all the challenges that small farmers face and I wanted to have an impact on them.”
To this day, Camarillo believes in the power of education. Her schooling took her all the way to the International Maize and Wheat Improvement Center (CIMMYT), where she is now not only a researcher, but an educator herself. After her extensive study of plant breeding, genetics and wheat physiology, Camarillo gained a masterâs degree from the University of Massachusetts, Amherst, and a PhD from Texas A+M University.
She was a part of CIMMYTâs fellowship program while pursuing her doctorate, and she joined the organizationâs wheat breeding team shortly afterward. Camarillo now splits her time between wheat research and organizing the training activities for CIMMYTâs Global Wheat Program (GWP) wheat improvement course.

A special legacy
CIMMYTâs wheat improvement course is an internationally recognized program where scientists from national agricultural research programs (NARS) from around the world travel to CIMMYT Headquarters in Texcoco, Mexico, and then to Ciudad ObregĂłn, for a 16-week training. Participants observe an entire breeding cycle and learn about the latest technologies and systems for breeding.
“A crucial component of having an impact on farmers is establishing good relationships with national programs, where all the germplasm that CIMMYT develops is going to go,” says Camarillo. “But at the same time, these partners need training. They need to know what is behind these varieties and the process for developing them, and we try to keep them updated with the vision, the current technologies and the breeding pipeline.”
The organization’s university-focused training programs are also special to Camarillo for many reasons, having participated in one of them herself. In fact, her first ever exposure to CIMMYT was through the annual Open Doors day which she attended during her first year of university, watching the breeders and scientists that would eventually become her colleagues give talks on germplasm development and distribution.
The courses also give students a chance to see all how their theoretical education can be applied in the real world. “When you are in graduate school you care a lot about data analysis and the most recent molecular tools,” says Camarillo. “But there is something else out there, the real problems outside. By taking the breeding program course you understand these challenges and situations.”
Camarillo remembers being struck by the thought that something that happens in a research station in Mexico can have an impact on the whole world. “CIMMYT cares about how other countries will adopt new varieties, itâs not just about developing germplasm for the sake of it,” she explains. “Weâre interested in how new varieties are going to reach the farmers who need them, and for that, training is essential.”
“At the end of the day, these researchers are the ones who will help us evaluate germplasm. If theyâre well trained, the efficiency of the whole process will increase.”

Keeping an eye on the breeding pipeline
With one foot in education and the other in research, Camarillo has a unique perspective on CIMMYTâs strategy for bringing tools and findings out of the lab, and towards the next step in the impact pathway. A key part of her work involves helping to research physiological traits by developing new tools to increase phenotyping efficiency in the breeding pipeline.
In particular, she is working on a project to develop high-throughput phenotyping tools, which use hyperspectral sensors and cameras to measure several traits in plants. This can help reflect how the plant is responding to different stresses internally, and helps physiologists and breeders understand how the plant behaves within a specific environment, and then quickly integrate these traits into the breeding process.
“Overall it increases the efficiency of selection, so farmers will have better materials, better germplasm, and more reliable yield across environments in a shorter period of time,” says Camarillo. Â
Sharing the recipe for success
Camarillo’s role in both breeding and training speaks to CIMMYTâs historic and proven strategy of working with national programs to effectively deliver improved seeds to the farmers who need them. In addition to developing friendships with trainees from around the world, she is helping CIMMYT to expand its global network of research and agriculture professionals.
As a product and purveyor of a great agricultural education, Camarillo is dedicated to it passing on. “I think we have to invest in education,” she says. “It is the only path to solve the current problems we face, not only in agriculture, but in every single discipline.”
“If we donât invest and take the time for education, our future is very uncertain.”
Scientists at the International Maize and Wheat Improvement Center (CIMMYT) have been harnessing the power of drones and other remote sensing tools to accelerate crop improvement, monitor harmful crop pests and diseases, and automate the detection of land boundaries for farmers.
A crucial step in crop improvement is phenotyping, which traditionally involves breeders walking through plots and visually assessing each plant for desired traits. However, ground-based measurements can be time-consuming and labor-intensive.
This is where remote sensing comes in. By analyzing imagery taken using tools like drones, scientists can quickly and accurately assess small crop plots from large trials, making crop improvement more scalable and cost-effective. These plant traits assessed at plot trials can also be scaled out to farmers’ fields using satellite imagery data and integrated into decision support systems for scientists, farmers and decision-makers.
Here are some of the latest developments from our team of remote sensing experts.

Measuring plant height with high-powered drones
A recent study, published in Frontiers in Plant Science validated the use of drones to estimate the plant height of wheat crops at different growth stages.
The research team, which included scientists from CIMMYT, the Federal University of Viçosa and KWS Momont Recherche, measured and compared wheat crops at four growth stages using ground-based measurements and drone-based estimates.
The team found that plant height estimates from drones were similar in accuracy to measurements made from the ground. They also found that by using drones with real-time kinematic (RTK) systems onboard, users could eliminate the need for ground control points, increasing the dronesâ mapping capability.
Recent work on maize has shown that drone-based plant height assessment is also accurate enough to be used in maize improvement and results are expected to be published next year.

Advancing assessment of pests and diseases
CIMMYT scientists and their research partners have advanced the assessment of Tar Spot Complex â a major maize disease found in Central and South America â and Maize Streak Virus (MSV) disease, found in sub-Saharan Africa, using drone-based imaging approach. By analyzing drone imagery, scientists can make more objective disease severity assessments and accelerate the development of improved, disease-resistant maize varieties. Digital imaging has also shown great potential for evaluating damage to maize cobs by fall armyworm.
Scientists have had similar success with other common foliar wheat diseases, Septoria and Spot Blotch with remote sensing experiments undertaken at experimental stations across Mexico. The results of these experiments will be published later this year. Meanwhile, in collaboration with the Federal University of Technology, based in Parana, Brazil, CIMMYT scientists have been testing deep learning algorithms â computer algorithms that adjust to, or âlearnâ from new data and perform better over time â to automate the assessment of leaf disease severity. While still in the experimental stages, the technology is showing promising results so far.

Improving forecasts for crop disease early warning systems
Early detection is crucial to combatting disease epidemics and CIMMYT researchers and partners have been working to develop a world-leading wheat rust forecasting service for a national early warning system in Ethiopia. The forecasting service predicts the potential occurrence of the airborne disease and the environmental suitability for the disease, however the susceptibility of the host plant to the disease is currently not provided.
CIMMYT remote sensing experts are now testing the use of drones and high-resolution satellite imagery to detect wheat rusts and monitor the progression of the disease in both controlled field trial experiments and in farmersâ fields. The researchers have collaborated with the expert remote sensing lab at UCLouvain, Belgium, to explore the capability of using European Space Agency satellite data for mapping crop type distributions in Ethiopia. The results will be also published later this year.

Delivering expert irrigation and sowing advice to farmers phones
The project has now ended, with the team delivering a webinar to farmers last October to demonstrate the app and its features. Another webinar is planned for October 2021, aiming to engage wheat and maize farmers based in the Yaqui Valley in Mexico.

Detecting field boundaries using high-resolution satellite imagery
In Bangladesh, CIMMYT scientists have collaborated with the University of Buffalo, USA, to explore how high-resolution satellite imagery can be used to automatically create field boundaries.
Many low and middle-income countries around the world donât have an official land administration or cadastre system. This makes it difficult for farmers to obtain affordable credit to buy farm supplies because they have no land titles to use as collateral. Another issue is that without knowing the exact size of their fields, farmers may not be applying to the right amount of fertilizer to their land.
Using state of the art machine learning algorithms, researchers from CIMMYT and the University of Buffalo were able to detect the boundaries of agricultural fields based on high-resolution satellite images. The study, published last year, was conducted in the delta region of Bangladesh where the average field size is only about 0.1 hectare.

Developing climate-resilient wheat
CIMMYTâs wheat physiology team has been evaluating, validating and implementing remote sensing platforms for high-throughput phenotyping of physiological traits ranging from canopy temperature to chlorophyll content (a plantâs greenness) for over a decade. Put simply, high-throughput phenotyping involves phenotyping a large number of genotypes or plots quickly and accurately.
Recently, the team has engaged in the Heat and Drought Wheat Improvement Consortium (HeDWIC) to implement new high-throughput phenotyping approaches that can assist in the identification and evaluation of new adaptive traits in wheat for heat and drought.
The team has also been collaborating with the Accelerating Genetic Gains in Maize and Wheat (AGG) project, providing remote sensing data to improve genomic selection models.
