Research Advances in Wheat Breeding and Genetics for Powdery Mildew Resistance

Powdery mildew (Blumeria graminis f. sp. tritici) significantly affects wheat yield and flour quality. Plant resistance to powderymildew has been investigated for decades, and numerous resistance genes and quantitative trait loci (QTLs) for molecular markers have beendiscovered. In Korea, powdery mildew occurs initially in spring, due to frequent rain and low temperatures, becoming severe during the harvestseason. In Korea, systematic monitoring and quantitative and qualitative impact assessments of powdery mildew outbreaks have never beenconducted properly. Herein, the lifecycle of powdery mildew, resistance genes, QTLs, and selection markers in wheat were examined to elucidatepowdery mildew resistance, develop resistant varieties, and genetic markers suitable for the domestic environment.
