  • 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.

  • Maize Blue Kernel Inbred Lines

    Lines developed through backcross breeding, which have grain with demonstrated enhanced levels of anthocyanin content. Landrace accessions identified through phenotypic evaluation to have useful levels of anthocyanin content and stability were used as donors. Elite CIMMYT Maize Lines (CMLs), selected with input from line and hybrid development breeders, were used as recurrent parents.

     

    Product details and features:

       

    1. Inbred lines of sub-tropical adaptation separated into “Tuxpeño” and “non Tuxpeño” heterotic groupings
    2. Inbred lines developed using recent and breeder-preferred CMLs

    Back to catalogue

    1. New inbred line sources within ±20% yield of MasAgro white sub-tropical hybrids

    2. Donor accession and recurrent parent line data, including passport, geographical information system (GIS)-derived, pedigree, phenotype and genotype available in searchable format through Germinate (http://germinate.cimmyt.org/).

    Comments

    These are improved materials suited for use in small to large research or breeding programs interested in exploring and using exotic kernel anthocyanin donor sources. Those interested in these products, especially those wanting to further, explore accessions for additional allelic variation for kernel pigmentation may also be interested in landrace panels for kernel pigmentation.
     

    Availability

    Available November 2020, but intermediate products are available on request
    50 seeds of each line available per request

    Primary Users

    Maize breeders for whom anthocyanin content is a crucial priority trait; maize breeders and geneticists investigating physiological and molecular basis of kernel pigmentation/antioxidant activity; researchers engaged in gene discovery for kernel pigmentation/antioxidant activity.

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.
