Genetic architecture of grain protein content in wheat

Studies on identification and localization of quantitative traits for grain protein content (QGpc-loci) on chromosomes in Triticum aestivum and Triticum durum are reviewed. Association of QGpc with various traits of morphology, physiology, adaptation and tolerance to abiotic and biotic stress is shown. Genetic and environmental QGpc contexts that should be taken into account when using molecular markers in breeding for the grain protein content are considered.
