More than 20 participants attended the genetic resources and seed production courses given by researchers from the Global Maize Program of the International Maize and Wheat Improvement Center (CIMMYT), from October 24 to 28 in Antigua, Guatemala. Among the attendees were technicians and researchers from the Institute of Agricultural Science and Technology (ICTA, for its acronym in Spanish), as well as students from Universidad Rafael Landívar and the University Centers of Chimaltenango (CUNDECH, in Spanish) and Quiché (CUSACQ, in Spanish) of Universidad de San Carlos de Guatemala.

Thanks to the support of the Global Environment Facility (GEF), the Tropical Agricultural Research and Higher Education Center (CATIE, in Spanish), the National Council for Protected Areas (CONAP, in Spanish) and the United Nations Environment Program (UNEP), these courses contributed to the development of a biosafety project, supported by GEF and UNEP, to complete the implementation process of the Cartagena Protocol through an innovative approach that promotes a strong link between biotechnology and biodiversity. In addition, it sought to strengthen capacities in the performance and interpretation of molecular analyses and promote the generational change that is gradually taking place in this Central American country.

Activities began on October 24 and 25 with the course on Statistics Applied to Genetic Resources given by Juan Burgueño, Head of CIMMYT’s Biometrics and Statistics Unit, to students from the aforementioned universities and ICTA staff interested in the analysis of molecular data for the purpose of characterizing accessions and the formation of core collections in germplasm banks. On the 26 and 27 of the same month, César Petroli, a specialist in high-throughput genotyping at CIMMYT, offered a course on biotechnology and high-throughput genotyping.

At the same time, Alberto Chassaigne, curator of the Maize Collection of CIMMYT’s germplasm bank, participated in the course on Genetic Resources and Management of Germplasm Banks. He explained the management of CIMMYT’s germplasm bank, the processes that are carried out and the partnerships with ICTA on work with community seed banks and the plans of both institutions for 2023. Also, as a specialist in Seed Systems, Chassaigne and Ubaldo Marcos, research assistant in CIMMYT’s Maize Seed Systems area, gave a course on Maize Seed Production. This course was aimed at staff in charge of the production of basic and certified seed at ICTA. This course concluded with a field day at the Regional Research Center of the South (CISUR, in Spanish), Cuyuta, Escuintla, where participants asked the specialists questions while visiting a maize seed production plot.

In turn, María de los Ángeles Mérida, a researcher specializing in genetic resources from ICTA, who organized these courses, spoke about the collection and conservation of native varieties of maize in Guatemala. Additionally, César Azurdia, CONAP biodiversity advisor, gave a presentation on wild relatives of different crops in Guatemala. Leslie Melisa Ojeda C. (CONAP) also participated, and spoke about the issue of legislation on crop wild relatives; and, Mynor Otzoy, a researcher from Universidad de San Carlos de Guatemala, spoke about the collection and morphological characterization of cocoa germplasm in Guatemala.

Along the path of constant strengthening of collaboration ties with countries, course participants highlighted their interest and need to continue this type of training. In 2023, it is expected to facilitate a team training with Ubaldo Marcos and Félix San Vicente, CIMMYT maize breeder for Latin America. It should be noted that, within the framework of the CGIAR germplasm bank initiative, the objective will be to replicate this experience in other Latin American countries and increase participation in community seed banks (ex situ and in situ banks).

Biofortified Maize for Improved Human Nutrition

Written by Emma Orchardson on . Posted in Uncategorized.

The Biofortified Maize for Improved Human Nutrition project conducts field research both at CIMMYT and with partners on breeding for increased pro-vitamin A and Zinc content in both Africa and Latin America. The project grant is renewed annually and has been in operation since 2004.

Key activities include supporting early and mid-late product development, evaluation and release in Mexico and target countries in southern Africa, food science and retention studies. Molecular breeding and biochemical analysis are key components for successful breeding, and the project also involves technical backstopping for partners in both regions.

Objectives

  • Conduct field research on breeding for increased pro-vitamin A for target countries in Africa
  • Conduct field research on breeding for increased Zinc for product evaluation and release
  • Conduct essential research to deploy analytical tools and marker assisted selection or genomic selection methods in micronutrient breeding work
  • Facilitate the dissemination, promotion and consumption of biofortified crops

The International Maize and Wheat Improvement Center (CIMMYT) maize germplasm bank recently received an award in recognition of its contributions towards the Buena Milpa initiative in Guatemala, which aims to enhance the sustainability of maize systems in the country. Denise Costich, head of the maize germplasm bank, received the award on behalf of CIMMYT during the event ‘Maize of Guatemala: Repatriation, conservation and sustainable use of agro-biodiversity,’ held on September 7, 2018, in Guatemala City.

The seed varieties stored in the CIMMYT germplasm bank were of vital importance in efforts to restore food security in the aftermath of Hurricane Stan, which swept through Guatemala in 2005, leading to 1,500 deaths. Many farmers lost entire crops and some indigenous communities were unable to harvest seed from their traditional maize varieties, known as landraces. Generations of selection by farmers under local conditions had endowed these varieties with resistance to drought, heat, local pests and diseases. Such losses were further exacerbated by the discovery that the entire maize seed collection in Guatemala’s national seed bank had been damaged by humidity; the seeds were vulnerable to insects and fungus and could not be replanted.

In 2016, drawing upon the backup seed stored in its maize germplasm bank in Mexico, CIMMYT sent Guatemalan collaborators seed of 785 native Guatemalan maize varieties, including some of the varieties that had been lost. Collaborators in Guatemala subsequently planted and multiplied the seed from the historic CIMMYT samples, ensuring the varieties grow well under local conditions. On completion of this process, the best materials will be returned to local and national seedbanks in Guatemala, where they will be available for farmers and researchers to grow, study and use in breeding programs.

Jointly hosted by the government of Guatemala through the Ministry of Agriculture, Livestock and Food and the Ministry of Culture and Sport, the recent ceremony signified the official delivery of the repatriated seed into the national system. Attendees celebrated the importance of maize in Guatemala and witnessed the presentation of repatriated maize collections to local and national Guatemalan seedbank authorities, including the Institute of Agricultural Science and Technology (ICTA).

“Supporting the seed conservation networks, on both the national and community levels in countries like Guatemala, is a key part of the mission of the CIMMYT Germplasm Bank,” said Costich. “Our collaboration with the Buena Milpa project has enabled the transfer of both seed and seed conservation technologies to improve the food security in communities with maize-centered diets.”

The Buena Milpa initiative in Guatemala is improving storage practices in community seed reserves: tiny, low-tech seed banks meant to serve as backups for villages in cases of catastrophic seed loss. So far, Buena Milpa has enabled 1,800 farmers to access community seed reserves. In addition, 13,000 farmers have applied improved practices and technologies.

The CIMMYT maize germplasm bank, headquartered in Mexico, serves as a backup for farmers and researchers in times of catastrophic seed loss by safeguarding maize genetic diversity, a crucial building block in global food security.
