Powdery mildew is one of the significant diseases in watermelon production,severely influencing the yield and quality of watermelon. The author presents the classification of physiological races of powdery mildew in watermelon,sta-tistical analysis of the regions where powdery mildew occurs in China,as well as the occurrence patterns and hazards of powdery mildew disease. The germplasm resources of watermelon resistant to powdery mildew reported in recent years are classified. Meanwhile,the genetic regularity of genes conferring resistance to powdery mildew,the development of molecular markers,and the disease-resistance regulatory networks are reviewed. New ideas and perspectives on the re-search of watermelon resistance to powdery mildew are proposed,aiming to offer references for the breeding of watermel-on varieties resistant to powdery mildew.
