• Wheat Iranian Landraces Core Set

    This core set of 249 Iranian wheat landrace accessions is representative of the approximately 2,500 Iranian wheat landraces available from CIMMYT’s germplasm bank. These accessions are of particular interest as Iran is within the center of origin for wheat, and contains warm environments; moreover, these landrace accessions are useful for broadening the genetic base for breeding wheat varieties. This core set was formulated using 20,000 DArTSeq genomic markers together with phenotypic data (heading, maturity, height, etc under heat, drought and irrigated condition as well as grain quality measures).

  • Comments

    The Iranian wheat landrace core set is 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.


    Currently available: Seeds of these landraces are available from CIMMYT’s germplasm bank. Request the Iranian wheat landrace core set.


    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, and grain filling period under heat and drought stresses.
