摘要: 小麦白粉病是威胁小麦的主要病害。实践证明,选育和应用抗病品种是解决小麦白粉病最经济、安全、有效的措施。近年来,分子标记技术的快速发展为小麦抗白粉病基因的研究奠定了基础。对小麦白粉病菌的形态特征、毒性频率、抗性基因来源、染色体定位、生理抗性、抗性基因应用等方面研究进展进行了综述,旨为小麦抗病育种提供参考依据。由于病原菌生理小种极容易变异,导致克服寄主原有抗性,可通过基因聚合使不同抗性基因实现有效结合,拓宽其抗谱,提高其抗性持久性,对小麦白粉病抗性研究具有重要理论和实践意义。

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
