• Wheat Mexican Landraces Core Sets


    These 1,100 core set accessions represent approximately 10,000 creole wheat landraces of Mexico brought by Spaniards and currently preserved at CIMMYT germplasm bank. Landrace core set accessions are promising for use in breeding wheat varieties with a broadened genetic base. These core sets are based on phenotypic traits (heading, maturity, height etc. under heat, drought and irrigated condition as well as grain quality measures). This core set was formulated using 20,000 DArT-seq markers as genotypic data simultaneously with phenotypic data.

  • 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 at CIMMYT wheat Germplasm Bank. Interested researchers are already making a request to CIMMYT Germplasm Bank for Mexican and Iranian wheat landrace core sets.



    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, grain filling period under heat and drought stresses etc.
