摘　　要：小麦(Triticum aestivum L.)地方品种具有丰富的遗传多样性,其中蕴含着丰富的抗白粉病基因,为小麦遗传改良和抗病育种提供了优异的抗源。就中国小麦地方品种抗白粉病研究进行了综述,包括抗病资源筛选鉴定、抗病性遗传分析、抗病基因定位及分子标记研究等,探讨了利用地方品种抗源进行小麦育种存在的问题,并对其发展前景进行了展望。Wheat landraces in China are rich in genetic diversity for powdery mildew resistance gene, providing precious ge-netic resources for genetic improvement and disease resistance breeding. Advances in research on powdery mildew resistance of wheat landraces were reviewed in this paper, which include identification of resistance resources, genetic analysis on dis-ease resistance, chromosome location and molecular mapping of resistance gene. The problems and perspective on the breed-ing for disease resistance in wheat landraces were proposed.
