A novel QTL discovered for grain protein content without grain weight penalty in wheat (Triticum aestivum L.)

Key Points

• Grain protein content is enhanced without increasing grain weight penalty, suggesting a significant genetic advance.
• The identified QTL presents an opportunity to improve wheat crop quality without compromising yield.
• Assessment using trait mapping across various wheat lines demonstrated the distinct locus associated with grain protein levels.
• Highlights potential for breeders to select for quality traits, fostering better nutritional profiles in wheat crops.
