The many colors of maize, the material of life

Written by Jennifer Johnson on . Posted in Features.

Tonahuixtla, a small town located in Mexico’s state of Puebla, had suffered extreme environmental degradation due to deforestation and erosion. Agricultural land was in poor condition and the town had stopped producing many of their heirloom maize varieties, a loss to both biodiversity in the region and local culture. Poverty had increased, forcing many to migrate to bigger cities or to the United States for work. Those who were left behind, most of them women, had few ways to generate income to support their families.

Today, the story of Tonahuixtla is different. The town actively participates in reforestation and erosion-prevention activities. Landrace maize production is increasing, preserving the town and region’s biodiversity and customs. The residents have job opportunities that allow them to stay in their town and not migrate, all while preserving local biodiversity and protecting the environment.

What caused this change?

Corn husks.

Long considered a waste product, corn husks have been given a new lease on life through the Totomoxtle project. Named for the traditional indigenous Nahuatl word for corn husk, Totomoxtle turns the husks of native maize, found in a variety of colors, into a beautiful and sustainable veneer for furniture and walls. Founded by Mexican graphic designer Fernando Laposse, Totomoxtle has given farmers an incentive to plant native maize again, preserving invaluable biodiversity for future generations.

When Denise Costich, head of the maize collection of the germplasm bank at the International Maize and Wheat Improvement Center (CIMMYT), heard about the Totomoxtle project she knew she wanted to help. Passionate about preserving native maize, she and her team identified 16 landrace varieties from the CIMMYT maize collection that would produce husks in interesting colors and could grow well in the altitude and climate conditions of Tonahuixtla. She invited Laposse and project members to come visit the genebank and learn about CIMMYT’s work, and provided them with seed of the landraces they had identified.

“This is what we normally do in our work at the germplasm bank, we give people seed,” Costich said. “But this turned into a closer collaboration.”

Colorful collaboration

The maize germplasm bank team arranged for Totomoxtle project members to receive training in how to make controlled pollinations in the native maize varieties, at one of CIMMYT’s experimental stations.

“The technicians at CIMMYT’s Agua Fria station loved meeting the project members from Tonahuixtla, and immediately became passionate about the Totomoxtle project,” Costich said. “To this day, the technicians still save all of the colored corn husks from CIMMYT maize trials and send them to Tonahuixtla to provide them with additional material for their project.”

In the village of Tonahuixtla, project members — many of them women — work to iron the corn husks flat and glue them on to a stiff backing, then send them via courier to Laposse’s workshop in London where he uses them to create beautiful furniture and wall panels. This work allows the residents of Tonahuixtla to stay in their village and not be forced to migrate, all while preserving maize biodiversity and protecting the environment.

“Part of what this project is doing is also helping to keep families together — providing livelihoods so that people can stay in their communities, so that they don’t have to send all of their young people off to Mexico City or to the United States. To me, it’s really all connected,” Costich said.

The value of sustainability

The project also shows the intersection between biodiversity conservation and protecting the local environment. The maize husks used for the project are a sustainable and biodegradable material, and any residue from the maize husks that are not used for the Totomoxtle project are either fed to animals in the dry season or used to make fertilizer, which is then returned to the maize fields, a completely circular cycle in which nothing is wasted.

“I think that many of the communities that we work in really do understand the value and the importance of biodiversity,” Costich said. “In Tonahuixtla, the people are trying to reforest the hillsides in their region. They understand the connection between having no vegetation on the hills and having the rain water just roll right off the hills and into the temporary streams, thus losing that critically important resource. Over the years, as a result of the work they have done there, they have seen with their own eyes the improvement in the environment, not only that the hills are now covered with vegetation, but also they see a lot less runoff and erosion. I think that’s a really important lesson for everyone. I come from an ecology background, so I am always very excited to get involved in projects where it’s not just about maize, it’s about everything. It’s also about people’s lives, and nutrition, and the connections between them.”

Preserving local maize biodiversity is not just important for Tonahuixtla — it is important to all of humanity. Native maize varieties have adapted for thousands of years in farmers’ fields across Mesoamerica, developing natural resistance to local plant pests and diseases, as well as climatic conditions such as heat or drought. These native maize seeds, passed down generation to generation, could hold the key to developing improved maize varieties that can resist emerging maize diseases or extreme weather events related to climate change. If this biodiversity is lost, it represents a loss to global food security as a whole.

CIMMYT works to protect many of these native maize varieties in their germplasm bank, which is home to over 28,000 different collections of maize. Kept in cold storage under optimum conditions in the CIMMYT seed vault, these seeds are preserved for future generations and are available to anyone who needs them, including farmers such as those in Tonahuixtla, who had lost much of their native maize diversity.

“The biodiversity of cultivated plants is basically the guarantee for the future,” Costich said. “This is our security backup. Seed security is food security.”

Battling devastating viral diseases, also in plants

Written by Jennifer Johnson on . Posted in Features.

When a maize lethal necrosis (MLN) outbreak happened in Kenya in 2011, scientists knew they needed to act fast. This viral disease, new to Kenya, was decimating maize fields. Within a few years, the viral disease spread rapidly in eastern Africa, through both insect vectors and contaminated seeds. If the virus were to spread into southern or West Africa, it would spell disaster for the smallholder farmers across the continent who depended on maize as a staple crop and for their family’s income and livelihoods.

The International Maize and Wheat Improvement Center (CIMMYT) and its partners immediately took action to impose a strict seed quarantine and restrict the movement of seed between eastern Africa and other regions in Africa. In addition, they worked intensively on developing and disseminating improved maize cultivars with tolerance or resistance to MLN, undertook extensive surveillance efforts, and sensitized partners on the importance of producing and commercializing MLN-free seed.

Due to these efforts, in the last nine years MLN has not been reported in sub-Saharan Africa outside of eastern Africa.

On the occasion of a recent publication on Virus Research about how MLN was contained, we interviewed B.M. Prasanna, director of the Global Maize Program at CIMMYT and the CGIAR Research Program on Maize (MAIZE), to discuss the MLN success story, the global COVID-19 crisis, and the similarities in the challenge to tackle plant and human viral diseases.

What were some of the extreme measures CIMMYT had to take to stop the spread of MLN?

The first step that we had to take in the fight against MLN was to rigorously analyze seed for any possible contamination with MLN-causing viruses and restrict movement of seed from eastern Africa to southern Africa.

The second most important step was to sensitize the national partners and the commercial seed sector about the danger of seed contamination with MLN-causing viruses, and how seed contamination can lead to the proliferation or spread of the disease.

The third important step was to build a new MLN quarantine facility in Zimbabwe, in partnership with the National Plant Quarantine Institute. Only when that quarantine facility was functional in 2017, we reinitiated transfer of research material from CIMMYT’s breeding hub in Kenya to CIMMYT in Zimbabwe. Only when the materials were certified to be MLN-free both in Kenya and Zimbabwe, through plant-by-plant analysis using immunodiagnostic kits, the seed was multiplied and further distributed to partners. So, the principle of containment and effective management is extremely important, whether it is a plant viral disease or a human viral disease.

We must note here that in terms of scale and intensity, as well as global effects and implications, any plant disease, including MLN, cannot be compared with a pandemic like COVID-19, which has affected every aspect of our lives.

How do you think the COVID-19 pandemic is going to impact our food systems?

We are indeed in a grim situation. The pandemic will undoubtedly have a serious effect on food security.

Many countries which do not have enough food reserves or those where the food systems are vulnerable to shocks like this are suffering. The people’s capacity to procure inputs for agriculture, including seed, is going to be affected too, as the markets are affected. This is really a serious situation that we all should be concerned about. The CGIAR has an important role to play, in terms of working closely with national partners and mitigating the impact of COVID-19 on agriculture.

We should be particularly worried about farmers, especially smallholder farmers, who are quite vulnerable to the ongoing challenge. Even without COVID-19, agriculture in many developing countries worldwide has been already under distress. Small and marginal farmers were often unable to find a market for their produce and earn sufficient income to support their families. Their livelihoods are fragile, and vulnerable to climate change and volatile market prices. The ongoing COVID-19 crisis is unfortunately compounding the crisis.

What lessons can agricultural research learn from this pandemic?

What do these pandemics or epidemics teach us? They remind us that systems need to be in place to prevent the proliferation of such diseases, whether it is plant diseases or animal diseases or human diseases. No country can be considered completely safe, and such diseases do not discriminate between a developed and a developing country, or the rich and the poor.

The second most important lesson is emergency preparedness. Whenever such devastating transboundary viral diseases show up, how quickly the country can respond — containing that infected area and not allowing the disease to spread, and then mitigating the damage systematically and quickly — is key. This is not the first time that a disease like MLN has emerged. There could be more serious viral or fungal diseases that could emerge in the future due to various reasons, including changing climates, international trade, movement of human beings, air currents, etc.  There are multiple ways that diseases can go across continents, across countries within a continent, and within countries. Therefore, the key is how well we can capacitate the national systems to be able to proactively prevent, detect, and intervene very fast.

Another big lesson here for agricultural systems is that a problem that happens in some other continent cannot be ignored because you work in a different continent. What COVID-19 shows is that the world is far more connected than we think.

For you, what is the biggest takeaway from the MLN success story?

I won’t say it is still a complete success. Through intensive partnerships and efforts, we were able to prevent the disease from devastating maize production in millions of smallholder farmers’ fields in sub-Saharan Africa. Since 2014, there has been no new country in Africa — outside eastern Africa — that has reported an outbreak of MLN. That, to me, is a tremendous success.

The work is still not over. The journey has to continue. And we still need to make sure that countries are continuously protected from devastating diseases like MLN. MLN is still not eradicated from eastern Africa. It may not be even possible to completely eradicate this disease, as the two viruses that together cause it can survive not just on maize but on multiple grasses. We can however contain the disease and limit its impact through continued efforts, like what we have done for the past 7 or 8 years. But if we lower our guard, there is a very high likelihood that the disease can still spread to other countries in sub-Saharan Africa, especially the major maize-growing countries in southern Africa or West Africa. Efforts need to continue. So, let us continue to maintain a high vigil to protect the smallholders in Africa from transboundary diseases like MLN.

Blue maize is all the rage, but are consumers willing to pay?

Written by Jennifer Johnson on . Posted in Features. 2 Comments on Blue maize is all the rage, but are consumers willing to pay?

Step into supermarkets or restaurants in Mexico City and surrounding towns and you might see products made from blue maize — food which would not have been available just a few years ago. Some of Mexico’s favorite dishes are taking on a new hue with blue corn chips, blue tortillas or blue tamales. But should breeders, millers, processors and farmer organizations invest in expanding the production of blue maize and blue maize products? Are consumers really interested, and are they willing to pay more?

These are some of the questions researchers at the International Maize and Wheat Improvement Center (CIMMYT) in Mexico set out to answer. They set up study to test consumer preferences and willingness to pay for this blue maize tortillas.

Maize is a main staple crop in Mexico and tortillas form the base of many traditional dishes. Blue maize varieties have existed for thousands of years, but until recently they were mostly unknown outside of the farming communities that grew them. In addition to its striking color, the grain has gained popularity partly due to its health benefits derived from anthocyanin, the blue pigment which contains antioxidants.

“Demand for blue maize has skyrocketed in the past few years,” said Trent Blare, economist at CIMMYT and the leader of the research.” Three years ago, white and blue maize sold at the same price. One year ago, blue maize cost just a few Mexican pesos more, and now blue maize is worth significantly more. However, we still lack information on consumer demand and preferences.”

According to Blare, the end goal of the study is to explore the demand for blue maize and try to better understand its market potential. “If we want farmers who grow blue maize to be able to get better market value, we have to know what the market looks like.”

This research received funding from Mexico’s Agency for Commercialization Services and Agricultural Market Development (ASERCA), which has been working with farmer organizations on post-harvest storage solutions for their maize. As blue maize is softer than typical white or yellow varieties, it requires special storage to protect it against insects and damage. In order to help provide farmers with the correct maize storage technology, ASERCA and others in Mexico will benefit from a deeper understanding of the market for blue maize in the region. In addition, researchers were interested to know if there is a premium for growing blue maize, or for making tortillas by hand. Premiums could help convince farmers to invest in post-harvest technologies and in the production of blue maize.

“There is this idea that demand should come from producers, but there are many steps along the maize value chain. We’re basically going backwards in the value chain: is there demand, is there a market, going all the way from the consumer back to the farmer,” Blare explained.

“There was an interesting gender aspect to this research: it was mostly women buying and making these maize-based foods, and women were more willing to pay a premium for blue maize,” said Miriam Perez (right), research assistant and interviewer. (Photo: Carolyn Cowan/CIMMYT)

A matter of taste

The study was conducted in Texcoco, just outside of Mexico City, where CIMMYT’s global headquarters are based. This town in the State of Mexico was chosen because of its long history growing and consuming blue maize. Interviews were held in three different locations, a local traditional market and two local shopping malls, in order to ensure that different socioeconomic groups were included.

“There is a certain pride in the blue tortilla. As Mexicans, the tortilla is something that brings us together,” said Mariana Garcia Medina, research assistant and interviewer. (Photo: Carolyn Cowan)

The team interviewed 640 consumers, asking questions such as where do they buy different types of tortillas, in which dishes they use different types of tortillas and if they faced difficulties in purchasing their preferred tortilla. The team also conducted sensory analysis and attributes, and gave study participants a choice between handmade blue maize tortillas, handmade white maize tortillas, and machine-made white maize tortillas.

The interviewees were given three different scenarios. Would they be willing to pay more for blue tortillas compared to other tortillas if eating quesadillas at a restaurant? To serve during a special event or visit from a family member? For everyday use?

The answers allowed researchers to quantify how much more consumers were willing to pay and in what circumstance, as they were given different price points for different types of tortillas in different scenarios.

True colors

The researchers found that preferences for blue and white maize were distinct for different dishes, and that there was a particular preference for blue maize when used in traditional dishes from this region, such as tlacoyos or barbacoa. A majority of consumers was willing to pay more for higher quality tortillas regardless of the color, as long as they were made handmade and fresh from locally grown maize. Interviewers also saw a noticeable difference in preference for blue tortillas depending on the situation: blue tortillas are demanded more for special occasions and in traditional markets.

“I found it fascinating that there is a difference in blue maize consumption based on the circumstance in which you are eating it.” Blare said. “This is one of the innovations in our demand study — not analyzing the demand for a food product in general but analyzing differences in demand for a product in different contexts, which is important as food is such an important component for celebrations.”

“We think there is potential to replicate this in other places in Mexico, to see consumer preference and price willingness for blue maize and other value-added maize products,” said Jason Donovan, senior economist at CIMMYT. “This will not just inform farmers and markets but also how to do this kind of research, especially in middle-income economies. This study is the first of its kind.”

“As a Colombian, it really surprised me that Mexicans were able to distinguish between white and blue maize tortillas even when blindfolded! It really shows the importance of maize to their diet and culture,” said Diana Ospina Rojas (left), research assistant and interviewer. (Photo: Carolyn Cowan/CIMMYT)

Still got the blue

Overall, the results revealed that women were willing to pay 33% more for blue maize tortillas while men were willing to pay 19% more. For every additional year of education, a consumer was willing to pay 1% more for blue maize tortillas. Interestingly, a person’s income had no effect on her or his willingness to pay for more blue maize tortillas. Many people interviewed expressed a preference for blue maize, but commented that they cannot always find it in local markets.

The information collected in these choice experiments will help farmers, breeders, and other actors along the maize value chain make more informed decisions on how to best provide blue maize varieties to the public — and give consumers what they want.

“It was a very interesting experience, I’ve never participated in a survey like this before and I think it is important to take the time to think about our decisions about food,” said Brenda Lopez, one of the interviewees in the choice experiment. Lopez preferred the handmade tortillas, especially those made with blue maize. “I think they have more flavor,” she said. “I just bought handmade tortillas in the market before participating in this survey, but I had to buy white because there was no blue available.”

Another interviewee, Luis Alcantara, agreed. “I prefer blue because of the flavor, the texture, even the smell,” he said. “At home we eat machine-made tortillas because it is hard to find handmade tortillas, and even if you do, they are not blue. We would buy blue if we could.”

African leaders rely on science and technology to improve food security

Written by Jennifer Johnson on . Posted in Features.

Rural areas in Africa are facing unprecedented challenges. From high levels of rural-urban migration to the need to maintain crop production and food security under the added stress of climate change, rural areas need investment and support. The recent Africa Food Security Leadership Dialogue brought together key regional actors to discuss the current situation as well as ways to catalyze actions and financing to help address Africa’s worsening food security crisis under climate change.

Heads of state, ministers of agriculture and finance, heads of international institutions and regional economic commissions, Nobel laureates, and eminent scientists took part in the dialogue in Kigali, Rwanda, on August 5 and 6, 2019.

This high-level meeting was convened by core partners including the African Union Commission (AUC), the African Development Bank (AfDB), the Food and Agriculture Organization of the United Nations (FAO), the International Fund for Agricultural Development (IFAD), and the World Bank.

The Director General of the International Maize and Wheat Improvement Center (CIMMYT), Martin Kropff, participated in a session entitled “Leveraging science to end hunger by 2025”, where he discussed the challenges to adapt Africa’s wheat sector to climate change, and what CIMMYT is doing to help. Demand for wheat is growing faster than any other commodity, and sub-Saharan Africa has tremendous potential to increase wheat production. People in Africa consume nearly 47 million tons of wheat a year. However, more than 80% of that — 39 million tons— is imported and used for human consumption, costing the countries billions of dollars. Kropff discussed the great strides CIMMYT has made in supporting wheat production on the continent despite biological challenges such as Ug99, a dangerous strain of wheat rust native to east Africa.

“The potential for wheat production in Africa is tremendous; existing varieties already realize very high yields but poor agronomic practices often result in low yields,” Kropff said. “The challenges we have to tackle together are as much in reshaping policies in favor of wheat and develop the wheat market and surrounding infrastructure. Africa’s environment is friendly for wheat production, but it needs the right supporting policies to develop a sustainable wheat market.”

Kropff highlighted Ethiopia’s case. “Ethiopia has decided to become self-sufficient in wheat by 2025. CIMMYT is already talking to the government and working with the national system to assure the best varieties and technologies will be used. We are ready to do this with every single African nation that is interested in producing quality wheat.”

Climate change is also posing dire threats to maize, a key staple crop in sub-Saharan Africa.

We talked to Cosmos Magorokosho, CIMMYT researcher and project leader of the Stress Tolerant Maize for Africa (STMA) project, who attended the dialogue, on what CIMMYT can do to better support farmers in Africa’s rural communities.

How can projects such as Stress Tolerant Maize for Africa contribute to protecting food security in Africa in the face of climate change?

Stress-tolerant maize varieties can contribute by cushioning farmers against total crop failures in case of drought and heat stress, among other stresses during the growing season. In addition, stress-tolerant varieties can also yield well under good growing conditions, therefore benefiting farmers both during difficult growing seasons as well as those seasons when conditions are favorable for maize growth.

What can be done to support rural areas and smallholder farmers in Africa to improve food security?

Rural areas and smallholder farmers need support with climate resilient crop varieties, supporting agronomic practices, environment conserving farming practices, labor and drudgery- reducing farm operations, access to affordable finance, and rewarding markets for their produce.

What role can international research organizations such as CIMMYT play in this?

International agricultural research can unlock the potential of small holder farmers through the generation of new appropriate technologies, testing and helping farmers adopt those technologies, refining and fine tuning of new technologies, as well as scaling up and out of farmer-demanded technologies. International agriculture research can influence policy across and within borders, political divide, religion, ecologies, and diversity of farmers.

What would it take for CIMMYT to effectively move science from the lab and package it into solutions that can be disseminated and adopted by majority of small family farms in Africa?

CIMMYT should keep and broaden its engagement with farmers, policy makers, and continue with capacity enhancement of partners to reach scale and bring new cutting-edge smallholder-farmer appropriate technologies to farmers’ fields in the shortest possible timeframe.

New association formed to support smallholder native maize farmers in Mexico

Written by Jennifer Johnson on . Posted in Features. 3 Comments on New association formed to support smallholder native maize farmers in Mexico

Expert Mexican scientists and farmer cooperatives have formed a non-profit organization to support small-scale landrace maize farmers who continue to conserve and plant seeds of their own native heirloom varieties. The civil association, known as ProMaĂ­z Nativo, intends to work collaboratively on projects to improve the lives of native maize and milpa farm families. Group members include national and internationally recognized maize experts, ethnobotanists, socioeconomists, food and nutrition scientists, marketing experts, maize farmers and farmer groups.

The civil association has also created a collective trademark, Milpaiz, which can be used by farmers to demonstrate the authenticity of the native maize varieties they grow and sell. This trademark will certify that a farmer’s maize is native to their community and derived from their continuous selection of seed. It will also certify that it is grown by small farmers and that they are selling only the surplus of their crops after feeding their own family. The trademark will also make a transparent effort to connect these farmers to a culinary market which values the quality, rarity and history of their production.

“Mexico is the center of origin of maize, and home to much of its genetic diversity. This initiative will allow us to certify that products are truly landrace maize from smallholder farmers, so that the benefits reach the smallholder farmers that have provided us with this biodiversity,” said Flavio AragĂłn, a genetic resources researcher with Mexico’s National Institute for Forestry, Agriculture and Livestock Research (INIFAP).

Researchers like Aragon, members of farmer groups and local chefs attended the official launch of ProMaĂ­z Nativo on June 14, 2019, at the World Trade Center in Mexico City, during restaurant trade fair ExpoRestaurantes.

Edelmira Linares, ethnobotanist at the National Autonomous University of Mexico (UNAM) and member of the association, emphasized that the collective trademark Milpaiz covers all crops grown in the traditional milpa intercrop farming system in Mexico: maize, beans, squash, edible greens, amaranth, pumpkin seeds, and certain vegetables.

“The trademark will make it easier for income to reach the farmers, will allow smallholder farmers to sell their products in supermarkets and to have a legal presence,” said Amanda Galvez, a food chemist at UNAM and president of ProMaíz Nativo.

Fair and sustainable market growth

Many smallholder farmers continue to plant the same native maize varieties that their parents and grandparents planted, developed in their villages and regions and improved by farmer selection dating back to their ancestors. These varieties are prized by their local communities for their unique flavors, colors, texture and use in special dishes — and the global culinary community is catching on. Native maize, or landraces, have become extremely popular with chefs and consumers in the past few years, drawing attention and imports from across the world. However, increased demand can mean increased vulnerability for farmers.

Many maize experts in Mexico were concerned with how to best support and protect smallholder farmers navigating this increase in demand. Without guidelines and transparency, it is difficult to ensure that farmers are being fairly compensated for their traditional maize, or that they are able to save enough to feed their own families.

In a discerning culinary market, a symbol of certification such as the collective trademark could serve to differentiate the families who have long been the guardians of these native varieties from larger commercial farmers who acquire these heirloom seeds. But there was no pre-existing space for these guidelines to be determined and developed.

“There is a depth of expertise on maize in Mexico, but these experts all work at different institutions, making it more difficult for all of them to collaborate on a project like this,” said Martha Willcox, landrace improvement coordinator at the International Maize and Wheat Improvement Center (CIMMYT).

“The formation of this civil association is truly novel in the history of native maize in Mexico, and its strength comes from the expertise of its members, made up entirely of Mexican scientists and Mexican farmer co-ops,” Willcox explained.

She initiated and facilitated the formation of this group of scientists and continues to work closely with them as an advisor. “This association will help provide a space and network where these experts can work together and speak in one voice to support maize and maize farmers.”

CIMMYT does not have a seat in the association but has played a key role in its facilitation and has provided funding to cover logistics and fees related to the formation of the organization, through the CGIAR Research Program on Maize (MAIZE). Mexico’s National Commission for the Knowledge and Use of Biodiversity (CONABIO) has also participated in the logistics and facilitation of the formation of the organization.

Seeds of progress

Written by Jennifer Johnson on . Posted in Videos.

 

The maize seed sector in east and southern Africa is male-dominated. However, there are women working in this sector who are breaking social barriers and helping to improve household food security, nutrition and livelihoods by providing jobs and improved seed varieties to farmers.

Researchers from the International Maize and Wheat Improvement Center (CIMMYT) conducted interviews with women owners of seed companies in eastern and southern Africa. They shared information on their background, their motivation to start their businesses, what sets their companies apart from the competition, the innovative approaches they use to ensure smallholder farmers adopt improved seed varieties, the unique challenges they face as women in the seed sector and the potential for growth of their companies.

Shifting to a demand-led maize improvement agenda

Written by Jennifer Johnson on . Posted in Features.

Partners of the Stress Tolerant Maize for Africa (STMA) project held their annual meeting May 7–9, 2019, in Lusaka, Zambia, to review the achievements of the past year and to discuss the priorities going forward. Launched in 2016, the STMA project aims to develop multiple stress-tolerant maize varieties for diverse agro-ecologies in sub-Saharan Africa, increase genetic gains for key traits preferred by the smallholders, and make these improved seeds available at scale in the target countries in partnership with local public and private seed sector partners.

The project, funded by the Bill & Melinda Gates Foundation and the United States Agency for International Development (USAID), is led by the International Maize and Wheat Improvement Center (CIMMYT), and implemented together with the International Institute for Tropical Agriculture (IITA), national agricultural research systems and seed company partners in 13 countries in sub-Saharan Africa.

The meeting was officially opened by the Deputy Director of the Zambia Agriculture Research Institute (ZARI), Monde Zulu. “Maize in Africa faces numerous challenges such as drought, heat, pests and disease. Thankfully, these challenges can be addressed through research. I would like to take this opportunity to thank CIMMYT and IITA. Your presence here is a testament of your commitment to improve the livelihoods of farmers in sub-Saharan Africa,” she said.

The International Maize and Wheat Improvement Center (CIMMYT) and its partners are working together in the fight against challenges such as drought, maize lethal necrosis and fall armyworm. The STMA project applies innovative technologies such as high-throughput phenotyping, doubled haploids, marker-assisted breeding and intensive germplasm screening to develop improved stress-tolerant maize varieties for smallholder farmers. The project team is also strengthening maize seed systems in sub-Saharan Africa through public-private partnerships.

The efforts are paying off: in 2018, 3.5 million smallholder farmers planted stress-tolerant maize varieties in 10 African countries.

Yielding results

CIMMYT researcher and STMA project leader Cosmos Magorokosho reminded the importance of maize in the region. “Maize is grown on over 35 million hectares in sub-Saharan Africa, and more than 208 million farmers depend on it as a staple crop. However, average maize yields in sub-Saharan Africa are among the lowest in the world.” Magorokosho pointed out that the improved maize varieties developed through the project “provide not only increased yields but also yield stability even under challenging conditions like drought, poor soil fertility, pests and diseases.”

“STMA has proved that it is possible to combine multiple stress tolerance and still get good yields,” explained B.M. Prasanna, director of CIMMYT’s Global Maize Program and the CGIAR Research Program on Maize (MAIZE). “One of the important aspects of STMA are the partnerships which have only grown stronger through the years. We are the proud partners of national agricultural research systems and over 100 seed companies across sub-Saharan Africa.”

Keynote speaker Hambulo Ngoma of the Indaba Agricultural Policy Research Institute (IAPRI) addressed the current situation of maize in Zambia, where farmers are currently reeling from recent drought. “Maize is grown by 89% of smallholder farmers in Zambia, on 54% of the country’s cultivable land, but productivity remains low. This problem will be exacerbated by expected population growth, as the population of Zambia is projected to grow from over 17 million to 42 million by 2050,” he said.

Down to business

On May 8, participants visited three partner local seed companies to learn more about the opportunities and challenges of producing improved maize seed for smallholder farmers.

Afriseed CEO Stephanie Angomwile discussed her business strategy and passion for agriculture with participants. She expressed her gratitude for the support CIMMYT has provided to the company, including access to drought-tolerant maize varieties as well as capacity development opportunities for her staff.

Bhola Nath Verma, principal crop breeder at Zamseed, explained how climate change has a visible impact on the Zambian maize sector, as the main maize growing basket moved 500 km North due to increased drought. Verma deeply values the partnership with the STMA project, as he can source drought-tolerant breeding materials from CIMMYT and IITA, allowing him to develop early-maturing improved maize varieties that escape drought and bring much needed yield stability to farmers in Angola, Botswana, the Democratic Republic of the Congo, Tanzania and Zambia.

At QualiBasic Seed, STMA partners were given the opportunity to learn and ask questions about the company’s operations, including the seed multiplication process in Zambia and the importance of high-quality, genetically pure foundation seed for seed companies.

The fall armyworm, an invasive insect-pest native to the Americas, has caused significant damage to maize crops in sub-Saharan Africa since its arrival to the region in 2016. An integrated approach, including improved agronomic practices, is necessary in order to fight against the invasive caterpillar. However, little is known about the most effective agronomic practices that could control fall armyworm under typical African smallholder conditions. In addition, more information is needed on the impact of fall armyworm on maize yield in Africa, as previous studies have focused on data trials or farmer questionnaires rather than using data from farmer fields. In a new study published by researchers with the International Maize and Wheat Improvement Center (CIMMYT), investigators set out to understand the factors influencing fall armyworm damage and to quantify yield losses due to fall armyworm damage.

The study examined damage in smallholder maize fields in two districts of eastern Zimbabwe. “We estimated the yield losses due to fall armyworm damage at 11.57 percent in the study area. Extrapolated to the whole of Zimbabwe, this would amount to a loss of 200,000 tons of grain, or a value of more than $32 million using the average global price of maize of $163 per ton in 2018,” said Frederic Baudron, cropping systems agronomist at CIMMYT and main author of the study.

Practices such as infrequent weeding or planting on land that had previously been fallow were found to increase fall armyworm damage to maize — most likely because they increased the amount of fall armyworm host plants other than maize. Conversely, practices hypothesized to increase the abundance of natural enemies of fall armyworm — such as minimum and zero tillage or the application of manure and compost — were found to decrease fall armyworm damage. Intercropping with pumpkins was found to increase damage, possibly by offering a shelter to moths or facilitating plant-to-plant migration of the caterpillar. Fall armyworm damage was also higher for some maize varieties over others, pointing to the possibility of selecting for host plant resistance.

“Given the limited coverage of the study in terms of area and season, it would be interesting to replicate it all over the country through the involvement of governmental agricultural departments, so that we get the full picture around the fall armyworm problem at a larger scale,” said Mainassara Zaman-Allah, co-author of the study and abiotic stress phenotyping specialist at CIMMYT.

This study is unique in that it is the first to collect information on agronomic practices that can affect fall armyworm damage using data taken directly from smallholder farmer fields. “Many papers have been written on pest incidence-damage-yield relationships, but with researchers often having control over some of the potential sources of variation,” said Peter Chinwada, TAAT Fall Armyworm Compact Leader at the International Institute of Tropical Agriculture (IITA), another co-author of the study.

“Our study was driven by the desire to determine fall armyworm incidence-damage-yield relationships under typical African smallholder farmer conditions which are characterized by a diversity of cropping systems, planting dates and “pest management practices” that may have been adopted for purposes which have nothing to do with managing pests. Unravelling such relationships therefore requires not only institutional collaboration, but the meeting of minds of scientists from diverse disciplines.”

The results of the study suggest that several practices could be promoted to control fall armyworm in its new home of Africa. “Farmers have already been informed of the results by their extension agents; the NGO GOAL, present in Zimbabwe, shared the findings,” Baudron said. “The next step is to test some of the recommendations suggested in the paper to control fall armyworm such as good weed management, conservation agriculture, use of manure and compost, and stopping pumpkin intercropping. These approaches will need to be refined.”

This work was implemented by the International Maize and Wheat Improvement Center (CIMMYT), GOAL, and the University of Zimbabwe. It was made possible by the generous support of Irish Aid, Bakker Brothers and the CGIAR Research Program on Maize (MAIZE).

International Women’s Day 2019: Women in seed systems in Africa

Written by Jennifer Johnson on . Posted in Features.

The maize seed sector in eastern and southern Africa is male-dominated. Most seed companies operating in the region are owned and run by men. Access to land and financial capital can often be a constraint for women who are keen on investing in agriculture and agribusiness. However, there are women working in this sector, breaking social barriers, making a contribution to improving household nutrition and livelihoods by providing jobs and improved seed varieties.

The Gender team within the International Maize and Wheat Improvement Center’s (CIMMYT) Socioeconomics Program conducted interviews with women owners of seed companies in eastern and southern Africa. They shared information on their background, their motivation to start their businesses, what sets their companies apart from the competition, the innovative approaches they use to ensure smallholder farmers adopt improved seed varieties, the unique challenges they face as women in the seed sector and the potential for growth of their companies. The resulting stories will be published as a report in May 2019.

These women in leading roles serve as mentors and examples to both male and female employees. In honor of International Women’s Day, held March 8, 2019, CIMMYT would like to share some of their stories to recognize these women — and many others like them — and the important work they do in seed systems in Africa.

Sylvia Horemans started Kamano Seeds in April 2004 together with her late husband Desire Horemans. The company derives its name from a stream that runs through their farm in Mwinilinga, Zambia. Kamano means a stream that never dries, aptly describing the growth the company has enjoyed over the years, enabling it to capture 15 percent of the country’s seed market share.  Sylvia became the company’s Chief Executive Officer in 2016.

“The initial business was only to sell commercial products but we realized there was a high demand for seed so we decided to start our own seed business,” says Sylvia. “We work with cooperatives which identify ideal farmers to participate in seed production.”

The company takes pride in the growth they have witnessed in their contract workers. “Most farmers we started with [now] have 20 to 40 hectares. Some are businessmen and have opened agrodealer shops where they sell agricultural inputs,” Sylvia announced.

Kamano prides itself in improving the lives of women smallholders and involving women in decision-making structures. “We empower a lot of women in agriculture through our out-grower scheme,” says Sylvia. She makes a deliberate effort to recruit women farmers, ensuring they receive payment for their seeds. “We pay the women who did the work and not their husbands.”

Zubeda Mduruma, 65, is a plant breeder. She took to agriculture from a young age, as she enjoyed helping her parents in the family farm. After high school, Zubeda obtained a bachelor’s degree in Agriculture. Then she joined Tanzania’s national agriculture research system, working at the Ilonga Agricultural Research Institute (ARI-Ilonga) station. She then pursued her master’s in Plant Breeding and Biometry from Cornell University in the United Stations and obtained a doctorate in Plant Breeding at Sokoine University of Agriculture in Tanzania, while working and raising her family. “I wanted to be in research, so I could breed materials which would be superior than what farmers were using, because they were getting very low yields,” says Zubeda. In the 22 years she was at Ilonga, Zubeda was able to release 15 varieties.

Aminata Quality Seeds is a family business that was registered in 2008, owned by Zubeda, her husband and their four daughters. Aminata entered the seed market as an out-grower, producing seed for local companies for two years. The company started its own seed production in 2010, and the following year it was marketing improved varieties. “I decided to start a company along the Coast and impart my knowledge on improved technologies, so farmers can get quality crops for increased incomes,” says Zubeda.

Zubeda encourages more women to venture into the seed business. “To do any business, you have to have guts. It is not the money; it is the interest. When you have the interest, you will always look for ways on how to start your seed business.”

Grace Malindi, 67, started Mgom’mera in Malawi in 2014 with her sister Florence Kahumbe, who had experience in running agrodealer shops. Florence was key in setting up the business, particularly through engagement with agro-dealers, while Grace’s background in extension was valuable in understanding their market. Grace has a doctoral degree in Human and Community Development with a double minor in Gender and International Development and Agriculture Extension and Advisory from the University of Illinois Urbana-Champaign in the United States. Mgom’mera is a family-owned enterprise. Grace’s three children are involved in the business, serving as directors.

Mgom’mera distinguishes itself from other seed companies because of its focus on maize varieties that have additional nutritive value. The company uses the tagline “Creating seed demand from the table to the soil.” It educates farmers not only on how to plant the seed they sell, but also on how to prepare nutritious dishes with their harvest. The company stocks ZM623, a drought-tolerant open-pollinated variety, and Chitedze 2, a quality protein maize. In the 2019 maize season it will also sell MH39, a pro-vitamin A variety. In addition, they are looking forward to beginning quality protein maize hybrid production in the near future, having started the process of acquiring materials from CIMMYT.

Grace observes that women entrepreneurs are late entrants in seed business. “You need agility, flexibility and experience to run a seed business and with time you will improve,” says Grace, advising women who may be interested in venturing into this male-dominated business.

International experts discuss progress and challenges of maize research and development in Asia

Written by Jennifer Johnson on . Posted in Features.

The importance of maize in Asian cropping systems has grown rapidly in recent years, with several countries registering impressive growth rates in maize production and productivity. However, increasing and competing demands — food, feed, and industry — highlight the continued need to invest in maize research for development in the region. Maize experts from around the world gathered to discuss these challenges and how to solve them at the 13th Asian Maize Conference and Expert Consultation on Maize for Food, Feed, Nutrition and Environmental Security, held from October 8 to 10, 2018, in Ludhiana, Punjab, India.

More than 280 delegates from 20 countries attended the conference. Technical sessions and panel discussions covered diverse topics such as novel tools and strategies for increasing genetic gains, stress-resilient maize, sustainable intensification of maize-based cropping systems, specialty maize, processing and value addition, and nutritionally enriched maize for Asia.

The international conference was jointly organized by the Indian Council of Agricultural Research (ICAR), the International Maize and Wheat Improvement Center (CIMMYT), the Indian Institute of Maize Research (ICAR-IIMR), Punjab Agricultural University (PAU), the CGIAR Research Program on Maize (MAIZE), and the Borlaug Institute for South Asia (BISA).

In Asia, maize is rapidly growing in its importance, due to high demand. Maize productivity in the region is growing by 5.2 percent annually compared to a global average of 3.5 percent. However, this is not enough. “Asia produces nearly 80 million tons of maize annually, but demand will be double by the year 2050,” said Martin Kropff, CIMMYT director general, in his opening address at the conference. “We need to produce two times more maize in Asia, using two times less inputs, including water and nutrients. Climatic extremes and variability, especially in South and South East Asia, will make this challenge more difficult. Continued funding for maize research is crucial. We need to work together to ensure that appropriate innovations reach the smallholder farmers.”

Climate-resilient maize and sustainable intensification

A major theme emphasized at the conference was climate resilience in maize-based systems. South Asia is a hotspot for vulnerability due to climate change and climate variability, which poses great risks to smallholder farmers. “Climate resilience cannot be brought by only a single technology — it has to be through a judicious mix of several approaches,” said B.M. Prasanna, director of CIMMYT’s Global Maize Program and the CGIAR Research Program on Maize.

Great advances have been made in developing climate-resilient maize for Asia since the last Asian Maize Conference, held in 2014. Many new heat- and drought-tolerant maize varieties have been developed through various projects, such as the Heat Stress Tolerant Maize for Asia (HTMA), and Affordable, Accessible, Asian (AAA) maize projects. Through the HTMA project, over 50 CIMMYT-derived elite heat-tolerant maize hybrids have been licensed to public and private sector partners in Asia during the last three years, and nine heat-tolerant maize hybrids have been released so far in Bangladesh, India and Nepal.

Sustainable intensification of maize-based farming systems has also helped farmers to increase yields while reducing environmental impact, through conservation agriculture and scale-appropriate mechanization. Simple technologies are now available to reduce harvest time by up to 80 percent and hired labor costs by up to 60 percent. Researchers across the region are also working to strengthen the maize value chains.

Science and appropriate technologies

CIMMYT has been focusing on developing and deploying new technologies that can enhance the efficiency of maize breeding programs; these include doubled haploid (DH) technology, high-throughput field-based phenotyping, and genomics-assisted breeding. The conference emphasized on the need for Asian institutions to adapt such new tools and technologies in maize breeding programs.

Another topic of interest was the fall armyworm, an invasive insect pest that has spread through 44 countries in Africa and was recently reported in India for the first time. “This pest can migrate very quickly and doesn’t require visas and passports like we do. It will travel, and Asian nations need to be prepared,” Prasanna said. “However, there is no need for alarm. We will be looking at lessons learned from other regions and will work together to control this pest.”

In addition to grain for food and feed, specialty maize varieties can provide beneficial economic alternatives for smallholder maize farmers. Conference participants had the opportunity to hear from Indian farmers Kanwal Singh Chauhan and Yugandar Y, who have effectively adopted specialty maize varieties, such as baby corn, sweet corn and popcorn, into life-changing economic opportunities for farming communities. They hope to inspire other farmers in the region to do the same.

On October 10, conference delegates participated in a maize field day organized at the BISA farm in Ladhowal, Ludhiana. Nearly 100 improved maize varieties developed by CIMMYT, ICAR and public and private sector partners were on display, in addition to scale-appropriate mechanization options, decision support tools, and precision nutrient and water management techniques.

The conference concluded with a ceremony honoring the winners of the 2018 MAIZE-Asia Youth Innovators Award. The awards were launched in collaboration between the CGIAR Research Program on Maize and YPARD (Young Professionals for Agricultural Development) to recognize the contributions of innovative young women and men who can inspire fellow youth to get involved in improving maize-based agri-food systems in Asia. Winners of the first edition of the awards include Dinesh Panday of Nepal, Jie Xu of China, Samjhana Khanal of Nepal, and Vignesh Muthusamy of India.

Better together: Partnership around zinc maize improves nutrition in Guatemala

Written by Jennifer Johnson on . Posted in Features.

On World Food Day, October 16, the International Maize and Wheat Improvement Center (CIMMYT) joins the Food and Agriculture Organization of the United Nations and partners around the world in their call to realize Sustainable Development Goal 2: Zero Hunger by 2030. Learn how CIMMYT, HarvestPlus and Semilla Nueva are working together to use biofortified zinc-enriched maize to reduce malnutrition in Guatemala, an important component of Goal 2.

Over 46 percent of children under five in Guatemala suffer from chronic malnutrition. More than 40 percent of the country’s rural population is deficient in zinc, an essential micronutrient that plays a crucial role in pre-natal and post-natal development and is key to maintaining a healthy immune system. CIMMYT, HarvestPlus and Semilla Nueva are working together to change this, through the development and deployment of the world’s first biofortified zinc-enriched maize.

“In Latin America, Guatemala is among the top 3 countries with the highest rates of zinc and iron deficiencies, and it is characterized by a high production and consumption of staple foods such as maize and beans. This made Guatemala, along with Haiti, the top prioritized countries for biofortification in the region, according to the Biofortification Priority Index (BPI) for Latin America,” said SalomĂłn PĂ©rez, the HarvestPlus country coordinator for Guatemala. HarvestPlus developed the BPI in 2013 to select the countries, crops and micronutrients in which to focus their efforts in Latin America. The BPI combines three sub-indexes: production, consumption and micronutrient deficiency level. “As maize is a staple food in Guatemala, with high levels of consumption and production, the development of biofortified maize with enhanced zinc was prioritized for the country,” he said.

Biofortified maize is a unique and efficient way of improving nutrition. As the nutrients occur naturally in the plant, consumers do not have to make any behavioral changes to get results. Rather than having to import supplements or fortify food, seeds and crops are sourced within the country, which makes this option more sustainable and accessible even in remote rural areas. It tastes the same as non-biofortified maize varieties and requires no special preparation methods. This made biofortification the obvious choice for improving zinc deficiency in Guatemala, and CIMMYT the obvious partner.

“CIMMYT has over 50 years of experience in tropical maize breeding for different traits,” said FĂ©lix San Vicente, one of the CIMMYT maize breeders leading the project. “Throughout our history we have developed elite materials with important agronomic and nutritional traits, such as Quality Protein Maize (QPM).”

The long lineage of zinc maize

Developed by CIMMYT scientists Evangelina Villegas and Surinder Vasal, QPM has enhanced levels of lysine and tryptophan, essential amino acids, which can help reduce malnutrition in children. Villegas and Vasal would later go on to win the World Food Prize in 2000 for this groundbreaking work, and genetic variation found in QPM would serve as the baseline for developing zinc-enriched maize.

After years of breeding work and research, the world’s first biofortified zinc maize hybrid, ICTA HB-18, was released in Guatemala in May 2018. It was developed by CIMMYT, the CGIAR Research Programs on Maize (MAIZE) and Agriculture for Nutrition and Health (A4NH), and Guatemala’s Institute for Agricultural Science and Technology (ICTA) with support from HarvestPlus. Commercialized by Semilla Nueva under the name Fortaleza F3, the biofortified zinc maize hybrid contains 6-12ppm more zinc and 2.5 times more quality protein compared to conventional maize varieties. An open pollinated variety, ICTA B-15, was also released.

Just 100 grams of tortilla made of either of these varieties can provide 2.5 milligrams of zinc, 50 percent of the daily recommended intake for children, making zinc-enriched biofortified maize an excellent tool in the fight against malnutrition and hidden hunger.

As CIMMYT is a breeding organization, it depends on national partners to get seeds to the farmers. That is where Semilla Nueva comes in. This non-profit social enterprise is working to get high yielding biofortified seeds to farmers in Guatemala.

The last mile

“We need to be able to impact farmers with our improved germplasm,” said San Vicente. “Semilla Nueva takes us to the last mile, to the farmers, which alone we could not do, so that our breeding work can achieve impact in farmers’ fields and lives.”

Semilla Nueva targets commercial farmers in Guatemala, as they are the main source of maize consumed in the country. Typically, a quarter of their harvest is consumed at home and surplus is sold in local markets, meaning that the zinc maize not only provides increased income to farmers, but also improves nutrition in their families, communities and country at large.

“CIMMYT, along with partners like HarvestPlus, have provided the technologies and support to allow us to come up with new ways to improve farmers’ lives. Tapping into decades of research from qualified scientists is the only way that an organization of our size can have hope of making an impact in the lives of millions of farmers. That’s what makes the partnership so incredible,” said Curt Bowen, executive director and cofounder of Semilla Nueva. “We provide the innovative way to get technologies to farmers through our social enterprise model. CIMMYT and HarvestPlus come up with the technologies that we never could have come up with on our own. Together, we help thousands of families make huge changes in their lives and take on malnutrition, which is one of the world’s biggest challenges to ending global poverty.”

Semilla Nueva plans to produce 5,000 bags of Fortaleza F3 next year, which will represent 5 percent of the Guatemalan hybrid seed market.

“Farmers have responded very positively to Fortaleza F3. They are convinced of its performance, especially during the dry season,” said Angela Bastidas, senior operations director at Semilla Nueva. “The way we approach farmers is not different than other seed companies; through farm visits, meetings, or field days. We are not reinventing the wheel. The difference with us has been offering farmers exactly what they need in terms of maize performance and price. Additionally, they find that our maize produces soft tortillas that taste better!” she explained.

In the end, the results speak for themselves. Fortaleza F3 increases yields by 13 percent and profits by $164 per bag compared to other mid-priced seeds, which goes a long way in improving farming families’ livelihoods, food security and nutrition.

“With Fortaleza F3, I pay less for the seed compared to other mid-priced competitors that I used to plant. F3 also yields more, giving me a greater profit,” said Rómulo González, a farmer from the southern coast of Guatemala. “With the extra income I’ve gotten since switching to F3, I’ve been paying for my daughter to go to school. Fortaleza F3 not only gave me a good harvest, but also the ability to support my daughter’s education.”

CIMMYT is pleased to announce the release of a set of 26 new CIMMYT maize lines (CMLs). These CMLs were developed by the CIMMYT Global Maize Program’s multi-disciplinary teams of scientists at breeding locations in sub-Saharan Africa, Latin America and Asia. These lines are adapted to the tropical/subtropical maize production environments targeted by CIMMYT and partner institutions. CMLs are freely available to both public and private sector breeders worldwide under the standard material transfer agreement (SMTA).

CIMMYT seeks to develop improved maize inbred lines with superior performance and multiple stress tolerance to improve maize productivity for resource-constrained smallholder farmers.  To achieve this aim, CMLs are released after intensive evaluation in hybrid combinations under various abiotic and biotic stresses.  Suitability as either seed or pollen parent is also thoroughly evaluated.

Release of a CML does not guarantee high combining ability or per se performance in all environments; rather, it indicates that the line is promising or useful as a hybrid component or parent for pedigree breeding for one or more target mega-environments. The descriptions of the lines include heterotic group classification, along with information on their specific combining ability with widely-used CIMMYT lines.

For a summary of the 26 new CMLs, please click here.

Further details on all CMLs, including the pedigrees, are available here.

A limited quantity of seed of the CMLs can be obtained from the CIMMYT Germplasm Bank. To send a request, please contact Denise Costich, Head of the Maize Genetic Resources Center: d.costich@cgiar.org.

Jie Xu.

An associate researcher at Sichuan Agricultural University, China, Jie Xu is interested in how maize roots influence performance under drought stress. By studying maize inbred lines that exhibit different drought tolerance, her research explores their genome and transcriptome variations to understand the genetic basis of plant adaptation to drought. The findings can then be used in breeding drought-tolerant maize.

Jie Xu and her team have developed methods to dissect the genetic and epigenetic mechanisms underlying maize drought stress response. This work involves the identification of non-synonymous SNPs and corresponding candidate genes for drought tolerance using analyses such as common variant and clustering techniques. Her team also revealed the impact smRNAs and histone modifications have in the regulation of maize drought stress response.

The first zinc-enriched maize varieties developed specifically for farmers in Guatemala were released this month as part of efforts to improve food and nutrition security in a country where over 46 percent of children under five suffer from chronic malnutrition.

More than 40 percent of Guatemala’s rural population have been found to be deficient in zinc, an essential micronutrient that plays a crucial role in pre-natal and post-natal development, and is key to maintaining a healthy immune system.

The new varieties, known as ICTA HB-18 and ICTA B-15, were developed by the International Maize and Wheat Improvement Center (CIMMYT), the CGIAR Research Programs (CRPs) on Maize (MAIZE) and Agriculture for Nutrition and Health (A4NH), and Guatemala’s Institute for Agricultural Science and Technology (ICTA), with support from HarvestPlus. The varieties will be commercialized by Semilla Nueva and Atescatel cooperative with the support of the Plataforma BioFORT, a network created to promote biofortification activities in the country formed by 30 public and private institutions. The official launch was held in Jutiapa, Guatemala, on May 4 with an event attended by over 100 Guatemalan maize producers.

“There are not many countries working with zinc maize right now, and that makes us pioneers in this area,” said Felix San Vicente, CIMMYT maize breeder. “Guatemala is the first country to release a zinc maize hybrid and Colombia will be the second. This means that we can also breed high zinc maize hybrids for producers who prefer hybrids over open pollinated varieties.”

These biofortified varieties were developed using conventional breeding methods. Farmers expressed interest in the varieties due to their high yield quality protein content, high zinc levels, early maturity and large kernel size.

Maize is a staple crop in Guatemala, and the base of many traditional foods such as tortillas, tamales, fresh roasted maize ears and other products. Tortillas made with ICTA B-15 contain up to 60 percent more zinc than regular tortillas. ICTA HB-18, a zinc maize hybrid, contains 15 percent more zinc compared to commercial maize. Just 100 grams of tortilla made of these varieties can provide 2.5 milligrams of zinc, 50 percent of the daily recommended zinc intake for children, making zinc-enriched biofortified maize an excellent tool in the fight against malnutrition and hidden hunger.

One hundred and thirteen tons of seed will be produced and delivered to producers by the end of 2018.
