KASP genotyping of loci associated with the “1000-grain weight” trait in common wheat (Tríticum aestívum L.)

Using the KASP technology, the allelic composition of TaTGW6-A1, TaGASR7-A1, TaCKX6-D1, and TaGs3-D1 loci associated with the 1000-grain weight trait was identified in 25 varieties and variety accessions of the common wheat of Belarusian and foreign breeding. Annotated DNA sequences were selected for modeling and synthesis of KASP primers. It was demonstrated that the examined genotypes had carried both favorable alleles associated with 1000-grain weight, and the alleles producing a negative effect on the trait under study. Six wheat accessions of Belarusian breeding were identified. They carried a complex of alleles positively correlating with the 1000-grain weight trait: variety Vestochka-17, accessions E-2318, E-2263, E-2298, E-1569, and E-2695.
