Genome wide association study of the whiteness and colour related traits of flour and dough sheets in common wheat

Abstract Flour whiteness and colour are important factors that influence the quality of wheat flour and end-use products. In this study, a genome wide association study focusing on flour and dough sheet colour using a high density genetic map constructed with 90K single nucleotide polymorphism array...
