Abstract: Wheat powdery mildew is the main disease that harms the field of wheat. It has been proved that breeding and application of resistant varieties are the most economical, safe and effective measures to solve wheat powdery mildew. In recent years, the rapid development of molecular marker technology has laid the foundation for the research of resistant genes of wheat powdery mildew. The morphological characteristics, virulence frequency, source of resistance gene and chromosome location, physiological resistance and application of resistance gene of wheat powdery mildew were reviewed, in order to provide reference for wheat disease resistance breeding. Because the physiological races of pathogenic bacteria are extremely susceptible to mutation, which leads to overcoming the host's original resistance, different resistance genes can be effectively combined through gene aggregation, the resistance spectrum can be broadened, and the resistance can be lasted. And it is of great theoretical and practical significance to study the resistance of wheat powdery mildew.

Key words: wheat, powdery mildew, molecular markers
