小麦抗白粉病基因的定位及其在育种中的应用研究进展

Researches on Powdery Mildew Resistant Genes and Its Breeding in Wheat

小麦白粉病是威胁小麦生产的重要病害之一。培育抗病品种是防治该病最为经济、安全和有效的途径。到目前为止,已有32个主效抗白粉病基因被定位在小麦不同的染色体上。本文对小麦抗白粉病基因的染色体定位、来源和利用等进行综述,并对小麦抗白粉病育种的策略进行了探讨。

Powdery mildew is one of the most serious diseases of common wheat wortd-wide, Breemng for resistant cultivars has proved to be an economical, effective and environmentally safe method to control this disease. Up to now, 32 gene loci （Pml-Pm32） for resistance to powdery mildew has been identified and located on different chromosome. In this paper, the chromosome location, the resource and utilization of wheat powdery mildew resistant genes were reviewed. At the same time, the countermeasure of control the powdery mildew in wheat was discussed.
