摘　　要：小麦白粉病是小麦的主要病害之一。以簇毛麦为抗源,采用杂交与辐射、组织培养相结合的方法,将簇毛麦的抗白粉病基因导入小麦。经抗病鉴定、系统选育和细胞学分析,选育出农艺性状较好、抗白粉病的小麦新种质。经DNA分析,证明簇毛麦抗白粉病基因(或染色体片断)已被导入小麦品种。Wheat powdery mildew is one of wheat main diseases.We used Haynaldia villosa as antigens,gene resistance to powdery mildew from Haynaldia villosa was introduced to wheat through crossing,radiation and young embryo culture.By disease resistant identification,systematic selection and cell analysis,we have selected high yield varieties and new germplasm with good agronomic characters and resistance to powdery mildew.By DNA analysis,gene resistant to powdery mildew from Haynaldia villosa has been joined to wheat varieties.
