Genome-wide association study and KASP marker development for flour color in winter wheat.

ABSTRACT: Flour color influences the quality of end-use products of common wheat (Triticum aestivum L.). To analyze the genetic basis of flour color, the flour brightness (FL*), red-green level (Fa*), yellow-blue level (Fb*), and whiteness (W) of 341 winter wheat materials grown during the 2019-2020 years and 2020-2021 years in Emin and Qitai were measured. A genome-wide association study was conducted using a wheat 40 K breeding chip with the MLM model. The coefficient of variation and generalized heritability of wheat flour color traits ranged from 0.62% to 22.23% and 55.52% to 83.48%, respectively. There were strong correlations across the flour color traits. GWAS identified 20 significant and stable SNP markers distributed across 16 loci, including 1 for FL* located on chromosome 5D; 6 for Fa*,
