Bi-parental mapping and genome-wide association studies for grain quality traits in winter wheat under contrasting soil moisture conditions
Wheat grain quality is characterized by parameters such as grain protein concentration (Gpc), grain ash concentration (Gac), kernel weight (Kw), kernel diameter (Kd), and kernel hardness (Kh). Grain protein determines dough strength and loaf volume, while kernel hardness and size impact milling efficiency. Drought stress at flowering time can cause floral organ necrosis, thus, decreasing the number of grains per spike and filled grain percentage, while drought stress during grain filling reduces kernel weight and size, but increases grain protein concentration. A previous study reported three ...
