With the participation of more than 30 researchers from four CGIAR Centers located in the Americas, a planning workshop for a new CGIAR Research Initiative, AgriLAC Resiliente, was held on April 4–6, 2022. Its purpose was to define the implementation of activities to improve the livelihoods of producers in Latin America, with the support of national governments, the private sector, civil society, and CGIAR’s regional and global funders, and partners.

“This workshop is the first face-to-face planning meeting aimed at defining, in a joined-up manner and map in hand, how the teams across Centers in the region will complement each other, taking advantage of the path that each Center has taken in Latin America, but this time based on the advantage of reaching the territories not as four independent Centers, but as one CGIAR team,” says Deissy Martínez Barón, leader of the Initiative from the Alliance of Bioversity International and CIAT.

AgriLAC Resiliente is an Initiative co-designed to transform food systems in Latin America and the Caribbean. It aims to increase resilience, ecosystem services and the competitiveness of agrifood innovation systems in the region. Through this Initiative, CGIAR is committed to providing a regional structure that enhances its effectiveness and responds better to national and regional priorities, needs and demands.

This Initiative is one of a number that the CGIAR has in Latin America and the Caribbean and consists of five research components:

  1. Climate and nutrition that seeks to use collaborative innovations for climate-resilient and nutritious agrifood systems;
  2. Digital agriculture through the use of digital and inclusive tools for the creation of actionable knowledge;
  3. Competitiveness with low emissions, focused on agroecosystems, landscapes and value chains, low in sustainable emissions;
  4. Innovation and scaling with the Innova-Hubs network for agrifood innovations and their scaling up;
  5. Science for timely decision making and the establishment of policies, institutions and investments in resilient, competitive and low-emission agrifood systems.

The regional character of these CGIAR Initiatives and of the teams of researchers who make them a reality in the territories with the producers, was prominent in the minds of the leadership that also participated in this workshop. Martin Kropff, Global Director, Resilient Agrifood Systems, CGIAR; Joaquín Lozano, Regional Director, Latin America and the Caribbean, CGIAR; Óscar Ortiz, Acting Director General of the International Potato Center; Jesús Quintana, Manager for the Americas of the Alliance of Bioversity International and CIAT; and Bram Govaerts, Director General of the International Maize and Wheat Improvement Center (CIMMYT), all stated the importance of CGIAR being central to every discussion in which the teams are co-constructing a greater consensus on what AgriLAC Resliente is, what it wants to achieve, the approach it will use, and the goals it aims to achieve through synergies among its five components.

Acting as an integrated organization is also an opportunity for CGIAR to leverage co-developed solutions and solve local challenges in the global South related to climate change and agrifood systems transformation. “Building the new CGIAR involves tons of collaboration and coordination. In this AgriLAC Resiliente workshop, we have had a dialogue full of energy focused on achieving real impact” highlighted Bram Govaerts. He continued, “this is an occasion to strengthen teamwork around this CGIAR Initiative in which the Integrated Agrifood System Initiative approach will be applied in the Latin American region, which is a very interconnected region” he pointed out.

One of the main results of this workshop is an opportunity to carry out the integration of the CGIAR teams in the implementation of the AgriLAC Resiliente Initiative, with applied science and the decisive role of the partners at each point of the region, as mechanisms for change.

In 2022, the research teams will begin to lay the groundwork for implementing the Initiative’s integrative approach to strengthen the innovations to be co-developed with partners and collaborators in the Latin American region, that encompass the interconnected nature of the global South.

Taming wheat blast

Written by Rodrigo Ordóñez on . Posted in Features.

As wheat blast continues to infect crops in  countries around the world, researchers are seeking ways to stop its spread. The disease — caused by the Magnaporthe oryzae pathotype Triticum — can dramatically reduce crop yields, and hinder food and economic security in the regions in which it has taken hold.

Researchers from the International Maize and Wheat Improvement Center (CIMMYT) and other international institutions looked into the potential for wheat blast to spread, and surveys existing tactics used to combat it. According to them, a combination of methods — including using and promoting resistant varieties, using fungicides, and deploying strategic agricultural practices — has the best chance to stem the disease.

The disease was originally identified in Brazil in 1985. Since then, it has spread to several other countries in South America, including Argentina, Bolivia and Paraguay. During the 1990s, wheat blast impacted as many as three million hectares in the region. It continues to pose a threat.

Through international grain trade, wheat blast was introduced to Bangladesh in 2016. The disease has impacted around 15,000 hectares of land in the country and reduced average yields by as much as 51% in infected fields.

Because the fungus’ spores can travel on the wind, it could spread to neighboring countries, such as China, India, Nepal and Pakistan — countries in which wheat provides food and jobs for billions of people. The disease can also spread to other locales via international trade, as was the case in Bangladesh.

“The disease, in the first three decades, was spreading slowly, but in the last four or five years its pace has picked up and made two intercontinental jumps,” said Pawan Singh, CIMMYT’s head of wheat pathology, and one of the authors of the recent paper.

The good fight

Infected seeds are the most likely vector when it comes to the disease spreading over long distances, like onto other continents. As such, one of the key wheat blast mitigation strategies is in the hands of the world’s governments. The paper recommends quarantining potentially infected grain and seeds before they enter a new jurisdiction.

Governments can also create wheat “holidays”, which functionally ban cultivation of wheat in farms near regions where the disease has taken hold. Ideally, this would keep infectable crops out of the reach of wheat blast’s airborne and wind-flung spores. In 2017, India banned wheat cultivation within five kilometers of Bangladesh’s border, for instance. The paper also recommends that other crops — such as legumes and oilseed — that cannot be infected by the wheat blast pathogen be grown in these areas instead, to protect the farmers’ livelihoods.

Other tactics involve partnerships between researchers and agricultural workers. For instance, early warning systems for wheat blast prediction have been developed and are being implemented in Bangladesh and Brazil. Using weather data, these systems alert farmers when the conditions are ideal for a wheat blast outbreak.

Researchers are also hunting for wheat varieties that are resistant to the disease. Currently, no varieties are fully immune, but a few do show promise and can partially resist the ailment depending upon the disease pressure. Many of these resistant varieties have the CIMMYT genotype Milan in their pedigree.

“But the resistance is still limited. It is still quite narrow, basically one single gene,” Xinyao He, one of the co-authors of the paper said, adding that identifying new resistant genes and incorporating them into breeding programs could help reduce wheat blast’s impact.

The more the merrier

Other methods outlined in the paper directly involve farmers. However, some of these might be more economically or practically feasible than others, particularly for small-scale farmers in developing countries. Wheat blast thrives in warm, humid climates, so farmers can adjust their planting date so the wheat flowers when the weather is drier and cooler. This method is relatively easy and low-cost.

The research also recommends that farmers rotate crops, alternating between wheat and other plants wheat blast cannot infect, so the disease will not carry over from one year to the next. Farmers should also destroy or remove crop residues, which may contain wheat blast spores. Adding various minerals to the soil, such as silicon, magnesium, and calcium, can also help the plants fend off the fungus. Another option is induced resistance, applying chemicals to the plants such as jasmonic acid and ethylene that trigger its natural resistance, much like a vaccine, Singh said.

Currently, fungicide use, including the treatment of seeds with the compounds, is common practice to protect crops from wheat blast. While this has proven to be somewhat effective, it adds additional costs which can be hard for small-scale farmers to swallow. Furthermore, the pathogen evolves to survive these fungicides. As the fungus changes, it can also gain the ability to overcome resistant crop varieties. The paper notes that rotating fungicides or developing new ones — as well as identifying and deploying more resistant genes within the wheat — can help address this issue.

However, combining some of these efforts in tandem could have a marked benefit in the fight against wheat blast. For instance, according to Singh, using resistant wheat varieties, fungicides, and quarantine measures together could be a time-, labor-, and cost-effective way for small-scale farmers in developing nations to safeguard their crops and livelihoods.

“Multiple approaches need to be taken to manage wheat blast,” he said.

In an article published in Nature Scientific Reports, a team of scientists led by wheat breeder Philomin Juliana from the International Wheat and Maize Improvement Center (CIMMYT) conducted a large genome-wide association study to look for genomic regions that could also be associated with resistance to wheat blast.

Juliana and fellow scientists found 36 significant markers on chromosome 2AS, 3BL, 4AL and 7BL that appeared to be consistently associated with blast resistance across different environments. Among these, 20 markers were found to be in the position of the 2NS translocation, a chromosomal segment transferred to wheat from a wild relative, Aegilops ventricosa, that has very strong and effective resistance to wheat blast.

The team also gained excellent insights into the blast resistance of the globally-distributed CIMMYT germplasm by genomic fingerprinting a panel over 4,000 wheat lines for the presence of the 2NS translocation, and found that it was present in 94.1% of lines from International Bread Wheat Screening Nurseries (IBWSNs) and 93.7% of lines from Semi-Arid Wheat Screening Nurseries (SAWSNs). Although it is reassuring that such a high percentage of CIMMYT wheat lines already have the 2NS translocation and implied blast resistance, finding other novel resistance genes will be instrumental in building widespread, global resilience to wheat blast outbreaks in the long-term.

The researchers used data collected over the last two years from CIMMYT’s IBWSNs and SAWSNs by collaborators at the Bangladesh Wheat and Maize Research Institute (BWMRI) and Bolivia’s Instituto Nacional de Innovación Agropecuaria y Forestal (INIAF).

Devastating fungal disease

Wheat blast, caused by the fungus Magnaporthe oryzae pathotype Triticum, was first identified in 1985 in South America, but has been seen in Bangladesh in recent years. The expansion of the disease is a great concern for regions of similar environmental conditions in South Asia, and other regions globally.

Although management of the disease using fungicide is possible, it is not completely effective for multiple reasons, including inefficiency during high disease pressure, resistance of the fungal populations to some classes of fungicides, and the affordability of fungicide to resource-poor farmers. Scientists see the development and deployment of wheat with genetic resistance to blast as the most sustainable and farmer-friendly approach to preventing devastating outbreaks around the world.

This work was made possible by the generous support of the Delivering Genetic Gains in Wheat (DGGW) project funded by the Bill & Melinda Gates Foundation, the U.K. Foreign, Commonwealth & Development Office (FCDO) and managed by Cornell University, the U.S. Agency for International Development’s Feed the Future initiative, the CGIAR Research Program on Wheat (WHEAT), the Indian Council of Agricultural Research (ICAR), The Swedish Research Council (Vetenskapsråd), and the Australian Centre for International Agricultural Research (ACIAR).

Asian scientists join cross-continental training to restrain wheat blast disease

Written by Mike Listman on . Posted in News.

With backing from leading international donors and scientists, nine South Asia wheat researchers recently visited the Americas for training on measures to control a deadly and mysterious South American wheat disease that appeared suddenly on their doorstep in 2016.

Known as “wheat blast,” the disease results from a fungus that infects the wheat spikes in the field, turning the grain to inedible chaff. First sighted in Brazil in the mid-1980s, blast has affected up to 3 million hectares in South America and held back the region’s wheat crop expansion for decades.

In 2016, a surprise outbreak in seven districts of Bangladesh blighted wheat harvests on some 15,000 hectares and announced blast’s likely spread throughout South Asia, a region where rice-wheat cropping rotations cover 13 million hectares and nearly a billion inhabitants eat wheat.

“Most commercially grown wheat in South Asia is susceptible to blast,” said Pawan Singh, head of wheat pathology at the International Maize and Wheat Improvement Center (CIMMYT), an organization whose breeding lines are used by public research programs and seed companies in over 100 countries. “The disease poses a grave threat to food and income security in the region and yet is new and unknown to most breeders, pathologists and agronomists there.”

As part of an urgent global response to blast and to acquaint South Asian scientists with techniques to identify and describe the pathogen and help develop resistant varieties, Singh organized a two-week workshop in July. The event drew wheat scientists from Bangladesh, India, Nepal and Mexico, taking them from U.S. greenhouses and labs to fields in Bolivia, where experimental wheat lines are grown under actual blast infections to test for resistance.

The training began at the U.S. Department of Agriculture-Agricultural Research Service (USDA-ARS) Foreign Disease-Weed Science Research facility at Fort Detrick, Maryland, where participants learned about molecular marker diagnosis of the causal fungus Magnaporthe oryzae pathotype triticum (MoT). Sessions also covered greenhouse screening for blast resistance and blast research conducted at Kansas State University. Inside Level-3 Biosafety Containment greenhouses from which no spore can escape, participants observed specialized plant inoculation and disease evaluation practices.

The group then traveled to Bolivia, where researchers have been fighting wheat blast for decades and had valuable experience to share with the colleagues from South Asia.

“In Bolivia, workshop participants performed hands-on disease evaluation and selection in the field—an experience quite distinct from the precise lab and greenhouse practicums,” said Singh, describing the group’s time at the Cooperativa Agropecuaria Integral Colonias Okinawa (CAICO), Bolivia, experiment station.

Other stops in Bolivia included the stations of the Instituto Nacional de Innovación Agropecuaria y Forestal (INIAF), Asociación de Productores de Oleaginosas y Trigo (ANAPO), Centro de Investigación Agrícola Tropical (CIAT), and a blast-screening nursery in Quirusillas operated by INIAF-CIMMYT.

“Scientists in South Asia have little or no experience with blast disease, which mainly attacks the wheat spike and is completely different from the leaf diseases we normally encounter,” said Prem Lal Kashyap, a scientist at the Indian Institute of Wheat and Barley Research (IIWBR) of the Indian Council of Agricultural Research (ICAR), who took part in the training. “To score a disease like blast in the field, you need to evaluate each spike and check individual spikelets, which is painstaking and labor-intensive, but only thus can you assess the intensity of disease pressure and identify any plants that potentially carry genes for resistance.”

After the U.S.A. and Bolivia, the South Asia scientists took part in a two-week pathology module of an ongoing advanced wheat improvement course at CIMMYT’s headquarters and research stations in Mexico, covering topics such as the epidemiology and characterization of fungal pathogens and screening for resistance to common wheat diseases.

The knowledge gained will allow participants to refine screening methods in South Asia and maintain communication with the blast experts they met in the Americas, according to Carolina St. Pierre who co-ordinates the precision field-based phenotyping platforms of the CGIAR Research Program on Wheat.

“They can now also raise awareness back home concerning the threat of blast and alert farmers, who may then take preventative and remedial actions,” Singh added. “The Bangladesh Ministry of Agriculture has already formed a task force through the Bangladesh Agricultural Research Council (BARC) to help develop and distribute blast resistant cultivars and pursue integrated agronomic control measures.”

The latest course follows on from a hands-on training course in February 2017 at the Wheat Research Center (WRC) of the Bangladesh Agricultural Research Institute (BARI), Dinajpur, in collaboration with CIMMYT, Cornell University, and Kansas State University.

Participants in the July course received training from a truly international array of instructors, including Kerry Pedley and Gary Peterson, of USDA-ARS, and Christian Cruz, of Kansas State University; Felix Marza, of Bolivia’s Instituto Nacional de Innovación Agropecuaria y Forestal (INIAF); Pawan Singh and Carolina St. Pierre, of CIMMYT; Diego Baldelomar, of ANAPO; and Edgar Guzmán, of CIAT-Bolivia.

Funding for the July event came from the Bangladesh Agricultural Research Institute (BARI), the Indian Council of Agricultural Research (ICAR), CIMMYT, the United States Agency for International Development (USAID) and the Bill & Melinda Gates Foundation (through the Cereal Systems Initiative for South Asia), the Australian Centre for International Agricultural Research (ACIAR), and the CGIAR Research Program on Wheat.

 

 

XXI Latin American Maize Meeting

Written by on . Posted in News. 1 Comment on XXI Latin American Maize Meeting

Bolivia’s National Agricultural, Livestock and Forestry Innovation Institute (INIAF) and the CIMMYT-Colombia office organized the XXI Latin American Maize Meeting (XXIRLM) held in Santa Cruz de la Sierra, Bolivia, on 29-31 October 2015.

The meeting was organized within the agricultural innovation framework around four themes: genetic resources and biotechnology, genetic improvement, special and biofortified maize, and climate change and sustainable agricultural intensification. An expert gave a lecture on each one of the themes, followed by presentations by representatives of the participating institutions, which were reinforced by previously selected posters.

Bolivia has 11 million inhabitants and is self-sufficient in maize, producing 1.1 million tons on 430,000 ha each year. However, maize production could increase sustainably through the use of technologies such as improved seed and adequate crop management practices, including crop rotations (for example, with soybean on the 1.2 million ha sown to this crop). The goal of the XXIRLM was to discuss these and other subjects.

Johnny Cordero, Vice Minister of Rural Development and Lands, opened the meeting, which was attended by Carlos Osinaga, INIAF Director General, and Tito Claure, Coordinator of INIAF’s Maize Program. Juan Rissi, IICA representative in Bolivia, gave the first talk and said that in this age of productivity and competition, innovation is at the core of the agricultural sector’s tasks. Countries should therefore significantly increase their investment in research and development, strengthen the INIAs, and develop regional integration mechanisms to include INIAs, universities, research centers, the private sector, and farmer associations.

In the area of genetic resources, Terrance Molnar, CIMMYT, said that CIMMYT holds the world’s largest collection of maize genetic resources, with more than 27,000 accessions, whose potential is currently being assessed through the Seeds of Discovery project with the aim of providing genetic resources, knowledge, and tools that maize networks can use to accelerate the development of improved varieties that tolerate climate change and contribute to food security and sustainability. Four key objectives now being targeted are: drought tolerance, resistance to tar spot (Phyllachora maydis), resistance to maize lethal necrosis, and developing blue maize germplasm. Álvaro Otondo, INIAF Bolivia, mentioned that the area comprising northwestern Argentina and southwestern Bolivia has been proposed as a possible center of origin of maize based on ceramic artifacts found there that date from 7500-6200 BC.

Researchers at La Molina University evaluated 335 highland maize accessions from Peru’s central highlands and classified them into 22 races. The criteria that best differentiated these accessions were related to the crop’s vegetative stage and yield components. Researchers at CIF Pairumani, Bolivia, talked about the valuable experience they’ve had educating young students on genetic resource conservation using storytelling and the game of dominoes.

Ricardo Sevilla from La Molina University, Peru, proposed forming bulks of maize races using native germplasm and, when necessary, introductions. These bulks are later improved using recurrent selection to increase the frequency of favorable alleles of genes conferring adaptive traits, which are usually present in low numbers in native varieties. Selection gains of 5-10% have been achieved using this approach, depending on the selection criteria and the method used (half sibs, full sibs, self-pollinated families). In the area of biotechnology, researchers from the Universidad Mayor de San Simón and CIF Pairumani indicated they’re using new tools such as molecular markers, genomics, and another culture to develop haploids of some maize populations.

Luis Narro from CIMMYT and Sidney Parentony from EMBRAPA reviewed the history of maize breeding and came to the conclusion that breeding methods should exploit heterosis through the development of simple hybrids whose seed should be accessible to farmers at the right time, in places where they are needed, at a fair price. Hybrid seed use varies greatly in South American countries where double, triple, and simple hybrids are sown. For example, the area sown to hybrid seed covers more than 90% of the maize area in Argentina and Venezuela, 80% in Bolivia, and less than 50% in Colombia.

In Andean countries such as Bolivia, Ecuador, and Peru, farmers plant hybrid seed only of tropical maize (called hard yellow maize) (its use is above 80%). As for the Andean highland maize that is sown at altitudes above 2500 masl, the area sown to hybrid maize is zero, since all of the area is sown to open-pollinated varieties.

The convenience of using new technologies such as molecular markers, genomics, and doubled haploids to accelerate breeding progress was discussed. Molecular markers, genomics, and doubled haploids are being implemented in Argentina and Brazil, and doubled haploids are being produced in Chile. Other countries in the region such as Bolivia and Ecuador are interested in these technologies and have working agreements with CIMMYT.

Talks on genetic improvement were given by representatives from Bolivia, Colombia, and Ecuador, who said that new yellow maize hybrids with at least one CIMMYT parent have been released in their countries. In the case of Andean highland maize, ongoing work in Bolivia aims to increase maize productivity and incorporate resistance to ear rot into “cusco” type maize.

In the area of special and biofortified maize, CIMMYT researchers Félix San Vicente and Aldo Rosales highlighted the importance of maize varieties that are biofortified with provitamin A and high zinc content. They also reported CIMMYT’s progress in developing and releasing germplasm with high zinc, provitamin A, lysine, and tryptophan contents. They stressed the need to avoid grain losses due to poor storage and maintain the quality of products made from biofortified maize until they reach the consumer. High protein quality hybrids have been released in Bolivia and Ecuador in the past two years, and INTA Argentina is studying the nutritional quality of local maize.

In the area of special maize, representatives from Bolivia, Ecuador, and Peru presented their work on “purple maize,” a type of maize with high anthocyanin content in the grain, cob, and stalk, whose nutraceutical properties are due to powerful antioxidants that help control obesity, diabetes, and high blood pressure, as well as prevent colon cancer and other diseases. Consumption of soft drinks, cookies, and desserts made from this type of maize has increased greatly in countries such as Peru. This type of maize is only grown by smallholder farmers; therefore, linking the purple maize production system to the food industry would be an excellent means of improving the livelihoods of thousands of smallholder farmers who live in the poorest areas where this and other types of special maize are sown.

In the area of climate change and sustainable agricultural intensification, Kai Sonder from CIMMYT described changes in the weather at both the global and regional levels and highlighted the need to develop new varieties that tolerate multiple biotic and abiotic stresses. He also said it is necessary to set up networks that include germplasm evaluation and crop management practices adapted to farmers’ work environments and social conditions and promote sustainable agriculture, including precision agriculture, which means doing the right thing in the right place at the right time. Researchers from INTA Argentina and INIA Peru provided information on conservation agriculture and emphasized pest control, mechanization based on farm size and the type of crop, and recommendations on post-harvest management of maize grain. Argemiro Moreno did a field demonstration of the benefits of using the GreenSeeker to make more efficient use of nitrogen.

During the XXIRLM, replicas of an ear of maize of the “cusco” type were presented to outstanding maize researchers such as Gonzalo Ávila and Tito Claure from Bolivia, and Ricardo Sevilla from Peru. Finally, José Luis Zambrano, INIAP Ecuador, announced that the XXIIRLM will be held next year in Ecuador. The XXRLM was held last year in Lima, Peru.

The meeting was attended by representatives of national and international seed companies, NGOs, local governments, an agricultural bank, Bolivian universities such as Francisco Xavier University in Chuquisaca, Gabriel René Moreno de Santa Cruz University, Universidad Mayor de San Simón in Cochabamba, Peru’s La Molina National Agricultural University, national research centers such as INTA-Argentina, INIAF-Bolivia, EMBRAPA-Brazil, CORPOICA-Colombia, INIAP-Ecuador, INIA-Peru, and international research organizations such as IICA, JAICA from Japan, KOPIA from Korea, CIAT, and CIMMYT.

Bolivia and CIMMYT partner to boost sustainable grain production

Nemesia Achacollo, Bolivia’s Minister of Rural Development and Land, joined CIMMYT Director General Dr. Thomas A. Lumpkin in the lobby of the Borlaug building during her visit earlier this year. The two signed a scientific collaboration agreement to strengthen food security in the Andean country last week in Bolivia.

Bolivia became the first  country in South America   to adopt the sustainable intensification strategy for agriculture that CIMMYT has used successfully in Mexico with the Sustainable Modernization of Traditional Agriculture project (MasAgro), and in countries in Africa and Asia through similar projects. The project in Bolivia will develop new, high-yielding maize varieties adapted to the country’s growing conditions that will be commercialized by the local seed sector. The project also plans to develop and to transfer new technologies for sustainable farming practices based on conservation agriculture principles. “When combined, these factors account for higher and more stable yields, and contribute to mitigate agriculture’s impact on the environment,” said CIMMYT Director General Dr. Thomas A. Lumpkin.

The agreement was signed during the “Day of Collaborative Evaluation of Maize Research” organized by INIAF. Hans Mercado, INIAF Executive Director General, outlined the main activities planned for the three years of work that have been initially approved for the project. These include: analyses of  commercial and family agriculture  systems to improve their economic  and ecologic performance; breeding  of maize varieties adapted to  Bolivia’s growing conditions; advice  on the development of a seed  production system that includes  private and public players; and  capacity building and training of  human resources at different levels  of specialization.

The ceremony was hosted by Bolivia’s Minister of Rural Development and Land, Nemesia  Achacollo, who announced an  investment of US$ 350,000 per year  in the rural development project.  She noted that the agreement was reached following her visit to CIMMYT earlier this year, when she had an opportunity to see and learn about MasAgro achievements in Mexico. Achacollo also stressed that INIAF had already introduced two maize hybrids developed by CIMMYT that yield seven tons per hectare, double the average yield obtained in Bolivia.

“CIMMYT celebrates Bolivia’s vision and leadership in investing in research for rural development,” said Lumpkin. “We hope that more countries in the region will follow Bolivia’s example and adopt similar strategies to strengthen food and nutritional security while also protecting the environment.”

A new building at the Ernest W. Sprague Experimental Station in Agua Fría, Puebla, was inaugurated on 8 April during a visit from Nemesia Achacollo, Bolivia’s Minister of Land and Rural Development.

With the new facilities, CIMMYT scientists will be able to generate and evaluate maize germplasm as well as expand offerings in doubled haploid (DH) services, seed production and training courses. Ciro Sánchez, the station superintendent, welcomed the group and explained how the station is managed. Achacollo cut the ribbon to inaugurate the building and start the tour.

Vijay Chaikam, CIMMYT DH specialist, explained the benefits of DH seed and the production-to-planting process. “The quality of the parents is most important and can ensure the type of seed that will be obtained,” he said. Achacollo toured the test plots to see the growth and performance of the DH program as well as work by the low tropics team and the hybrid seed production process. She was accompanied by B.M. Prasanna, director of the Global Maize Program, CIMMYT scientists and members of the Bolivian and Ecuadorian governments.

Visitors exchanged viewpoints on the struggles of farmers in their respective countries and how the technology could improve sustainable production in Latin America. Arturo Silva, leader of MasAgro-Maize, and Achacollo agreed on the importance of increasing collaboration for improving maize productivity.

CIMMYT strengthens partnerships in South America

Representatives from the national agricultural systems in Bolivia and Ecuador visited CIMMYT at El Batán, Mexico, from 7-9 April to lay the framework for future collaboration to improve maize production.

The meeting was preceded by a visit from Colombian officials and will be followed by a visit of officials from Peru at the end of April, completing initial talks between CIMMYT and the four South American countries. “We are determining how CIMMYT can work more quickly and concretely to help feed populations in alliance with these countries. Bolivia is self-sufficient in maize, but it could become an exporter,” said Luis Narro, plant breeder for CIMMYT in Colombia. “Ecuador is importing more, but the government has decided to achieve self-sufficiency in two years. So they want to know how CIMMYT can be more involved in solving the problem of production in these countries, and we hope to improve the lives of producers.” Visitors included Nemesia Achacollo, Bolivian minister for land and rural development; Gabriel Hoyos, executive director general of the National Institute of Agrarian and Forestry Innovation (INIAF, Bolivia); and José Luis Zambrano, director of research at Ecuador’s Autonomous National Institute of Agrarian Research (INIAP).

Presentations on advanced maize research at CIMMYT, including an introduction to MasAgro work in sustainable intensification were conducted for the delegation. After learning more about the extent of work undertaken by CIMMYT, Achacollo was impressed by the challenges facing Bolivia in establishing its own international quinoa center. The delegation members also visited the Agua Fría Experimental Station in Puebla, where Achacollo announced that the Bolivian government would create policies for young Bolivian researchers to train in similar facilities. “We must invest in future generations so that they can provide the foundation of agricultural knowledge,” she said. “We cannot be left behind.”

Two new maize hybrids released in Bolivia

Written by on . Posted in News.

maize-hybrids1Bolivia’s National Institute for Agricultural, Livestock and Forestry Innovation (INIAF), in collaboration with CIMMYT, released two new maize hybrids, INIAF H1 and INIAF HQ2, targeting drought-prone areas with high production potential. The release was announced at an event held on 13-14 June 2013 in Villa Montes and Yacuiba.

The new releases are single-cross hybrids derived from CIMMYT lines. INIAF H1 is a yellow flint hybrid with good lodging resistance and excellent husk cover; INIAF HQ2 is a yellow semi-dent hybrid with high protein content (quality protein maize, QPM) and moderate drought tolerance. Both were tested at Villa Montes, where they competed favorably with two widely sown commercial checks, yielding 7 t/ha despite the low (352 mm) rainfall during the growing season.

While Bolivia is self-sufficient in maize production with about 300,000 ha sown to maize and an average yield of 3.3 t/ha, climate change is starting to impact the agricultural sector just like in other Latin American countries. Weather conditions during the current crop season have been unfavorable for production due to persistent drought, and last week the government declared the region of Chaco, where 80% of the country’s maize is produced, a natural disaster area.

In the light of the challenges, Rubén Vaca, Sector Executive of Villa Montes, who led the event during the first day, congratulated INIAF on its achievements and noted their potential for increasing the profitability of maize production. Similar sentiment was expressed by Nemesia Achacollo, Minister of Land and Rural Development, and José Sosa, Minister of Energy and Hydrocarbons, who attended the event in Yacuiba on day two. Achacollo applauded the release of the hybrids and announced that “the Ministry is allotting 2 million US$ to INIAF to support their maize program.” As the Ministry of Energy and Hydrocarbons is also involved in agriculture, Sosa stated that the urea factory being built in Cochabamba will support the development of Chaco Tarijeño and the country as a whole. Marcial Rengifo, Sector Development Executive of Chaco Tarijeño in Yacuiba, then stressed the importance of the hybrids for Chaco farmers, and Jemy Gonzales, manager of the National Seed Company, committed to multiplying all the hybrids released by INIAF in the future to ensure that high quality seed is accessible to farmers in a timely fashion and at a reasonable price.

After Achacollo presented a hybrids release certificate to INIAF director general Gabriel René Hoyos Bonillas, the coordinator of INIAF’s Maize Program, Tito Claure, thanked everyone present and asked that INIAF’s collaboration with CIMMYT be maintained, adding that he “would join forces with all the national institutions involved in maize production.”

“We must promote QPM, which – due to its superior nutritional qualities – benefits both the people who consume it directly as well as pig farmers,” said Luis Narro, CIMMYT maize breeder and focal point for South America. Narro then encouraged INIAF to adopt doubled haploid technology to reduce the time required to develop new hybrids and indicated that the GreenSeeker handheld sensor could be used to optimize nitrogen fertilization in maize crops.

“The CIMMYT-INIAF collaboration that led to the hybrids release is part of CIMMYT’s regional efforts conducted jointly with an improved germplasm evaluation network in the lowland tropics of Latin America,” said Félix San Vicente, CIMMYT maize breeder for Latin America. “We are ready to strengthen these links in the future in order to be able to handle the negative impacts of climate change on the Chaco region in Bolivia,” he added.

At the end of the event, Narro and San Vicente received awards from the Bolivian authorities in recognition of their inter-institutional collaboration and joint successes.

Latin American maize breeders learn about doubled haploids

Doble-Haploid2The use of doubled haploids in maize breeding was first proposed more than half a century ago and dramatically reduces the time required to produce homozygous inbred lines. Though widespread in modern maize breeding programs, the technique is little used by public programs and small- and medium-scale seed companies, especially in developing countries, partly due to its complexity.

To gain greater knowledge and mastery of the theory and actual practice, during 26-30 November 2012, 28 maize breeders from private and public entities of 5 Latin American countries attended a course given in Spanish by CIMMYT maize experts at El Batán. Complementing a similar course given in English last August, the event covered haploid induction, chromosomal doubling, breeding using doubled haploid lines, and how to access CIMMYT’s doubled haploid line production services, including hands-on practice in identifying haploid kernels, the chromosomal doubling treatment, and assessing haploid induction rate.

Doble-Haploid1“This is a cutting-edge technology,” says Tito Clauré, Maize Program Coordinator at Bolivia’s Instituto Nacional Autónomo de Investigaciones Agropecuaria (INIAP). “We’re very happy with what we learned about double haploids, but we also attended excellent presentations on statistics, physiology, and database creation.” Clauré mentions that INIAP’s Maize Program is part of the Sustainable Modernization of Traditional Agriculture (MasAgro) project, and has received much useful germplasm from CIMMYT.

“The course was a very good experience for me,” says Victor Moran Rosas, a breeder at the seed company Semillas Berentsen in Mexico. “I’d read about (doubled haploids), but was able to practice all the steps.” Participants widely agreed that a great part of the course was being able to connect with other Latin American maize breeders.

Latin American ministers visit CIMMYT and develop food price crisis strategy

CIMMYT E-News, vol 5 no. 5, May 2008

may05Skyrocketing food prices recently brought Latin American agriculture ministers from 14 countries and development experts to CIMMYT to seek a way forward for a region characterized by serious rural poverty.

On 26 May 2008, ministers of agriculture and government officials from Belize, Bolivia, Costa Rica, Cuba, the Dominican Republic, Ecuador, El Salvador, Guatemala, Haiti, Honduras, Mexico, Nicaragua, Panama, and Venezuela, as well as representatives of international organizations working in agricultural development and the Mexican media—more than 70 persons in all—visited CIMMYT’s headquarters in Mexico to learn about the center’s work and discuss collaborative strategies for addressing the food price crisis. The visit was part of a two-day summit organized by Mexico’s agriculture (SAGARPA) and foreign relations (SRE) ministries, following up on recommendations from a regional summit on the same topic in Nicaragua earlier this month.

Speaking on behalf of the Alliance of Centers of the Consultative Group on International Agricultural Research (CGIAR) in his welcoming talk, CIMMYT Director General Tom Lumpkin emphasized the need to move from the present emergency to a permanent vision for addressing the crisis. “It appears that two decades of complacency about basic food production has finally given way to a sense of urgency,” Lumpkin said. “We must now transform that urgency into a long-term vision, making sensible investments in agricultural research and extension to provide food for our children and our grandchildren.”

Have policy makers forgotten small-scale farmers?

The rising cost of food is being felt around the world, especially by poor people in rural zones. Though often not on the radar screens of policymakers, the rural poor are numerous. A recent paper from the International Food Policy Research Institute (IFPRI) says there are more than 400 million small farms in developing countries, and that these are home to most of the world’s hungry and disadvantaged. In Latin America and the Caribbean, nearly 64% of the rural population lives below the poverty line, according to a report by the International Fund for Agricultural Development (IFAD). Over the last two decades, the number of poor people in rural areas in the region has increased in both absolute and relative terms, the report says.

SAGARPA and CIMMYT undertake new, joint projects

As the meetings closed, Lumpkin urged “…the governments of Mexico and other countries in the region to re-examine their relationship with CIMMYT and bring new backing for research to increase food production and farm productivity.” In the week following the visit and at the invitation of Mexico’s Secretary of Agriculture, Alberto Cárdenas Jiménez, the center has submitted proposals for joint SAGARPA-CIMMYT work to develop, test, and disseminate drought tolerant maize varieties, as well as management practices that reduce small-scale farmers’ losses of stored maize grain to insect pests.
