  • New video: Crop biodiversity for healthy, nutritious livelihoods

    Erratic weather, poor soil health, and resource shortages keep millions of maize and wheat farmers in developing countries from growing enough to feed their households and communities or to harvest a surplus to sell.

MasAgro Biodiversity, a component of the Sustainable Modernization of Traditional Agriculture (MasAgro) program, focuses on the utilization and conservation of valuable genetic resources with genetic diversity protected in germplasm banks. This program has the purpose of accelerating the development of Varieties of maize and wheat that can meet the nutrition and nutritional demands of a growing population, facing the challenges of climate change.

By characterizing the genetic configuration of CIMMYT germplasm bank collections, the evaluation of priority characteristics – such as drought tolerance, high temperatures and some diseases – and the development of bioinformatics tools that streamline its analysis, MasAgro Biodiversity has Generated a “platform for the utilization of genetic resources” of maize and wheat.

This platform puts several products at the disposal of the scientific community. MasAgro Biodiversity also offers some services in order to promote equity in access and benefits of the use of maize and wheat diversity.

  • Wheat Mexican Landraces Core Sets

    This core set of 1,100 accessions is representative of the approximately 10,000 creole wheat landraces of Mexico currently preserved in CIMMYT’s germplasm bank, which originate from wheat varieties brought to Mexico by Spaniards. . Landrace core set accessions are promising for use in breeding wheat varieties with a broadened genetic base. The core set was selected based on phenotypic traits (heading, maturity, height, etc. under heat, drought and irrigated conditions, as well as grain quality measures), combined with genotypic data using 20,000 DArT-seq markers.

    Product details and features

    1. The list of Mexican wheat landrace core set entries and their complete passport information are available.http://germinate.cimmyt.org/wheat/?groupId=63#groups
    2. Genotypic data for the landrace core set are available in Dataverse for downloading via http://germinate.cimmyt.org/wheat/?groupId=63#groups
    3. Their genetic diversity profile in form of principal component analysis is available

  • Comments

    The Mexican and Iranian wheat landrace core sets are currently in demand by researchers seeking sources of resistance to various biotic and abiotic stresses for use in their wheat improvement programs. Target environments: heat and drought prone stress environments. Target traits: secondary traits associated with heat and drought stress tolerance.

    Availability

    Currently available: Seeds of these entries are available from CIMMYT’s germplasm bank.

     

    Primary Users

    Wheat breeders, physiologists, geneticists and molecular biologists interested in investigating physiological mechanisms of biotic/abiotic stress tolerance as well as researchers pursuing gene discovery for various target traits in wheat such as biomass increase, grain size, grain weight, spike length, tiller number, culm strength, or grain filling period under heat and drought stresses.

PHILOSOPHY OF OUR APPROACH

PHILOSOPHY OF OUR APPROACH

So many accessions, so few data!

Many genebanks resemble libraries that lack sufficiently informative catalogs. The advent of next-generation DNA-sequencing platforms has made it possible to characterize the genetic diversity conserved in entire genebanks.

Information management

Generating new data by itself is insufficient if it cannot be effectively disseminated, queried, summarized, visualized, and analyzed. Data generation, therefore, has to go hand-in-hand with providing intuitive software and analysis tools to deal with the rapidly expanding datasets describing maize and wheat genetic resources.

Pre-breeding

A ‘reformatting’ of the diversity in genebanks into a more breeder-ready format could lower the barriers to mobilize novel genetic variation into breeding programs, which in good part are due to the dependency of gene effects on genetic backgrounds.

Traits with complex genetic architecture

Some of the most important challenges to agriculture need to be addressed by manipulating genetically complex characters controlled by small-effect alleles (yield potential, heat and drought tolerance, etc.).

Collecting germplasm.

The availability of sufficient numbers of genebank accessions does not appear to be a factor limiting the use of novel genetic variation in breeding programs, and a new initiative will secure the global network of genebanks of humanity’s major food crops for future generations.
