Proposed and reported wheat pre-breeding schemes. Germplasm bank accessions are genotyped while field and laboratory phenotyping is performed for various traits using sub-sets or core sub-sets of accessions. Genotypic and phenotypic information are used to form core subsets for phenotyping. Once trait donors are identified, these are used for crossing with elite lines (exotic/elite1//elite2), followed by selection under heat, drought and disease conditions during TC₁F₂ to TC₁F₅ generations. The advanced genotypes are distributed (these are currently available) on request to researchers across the world.
