| 摘 要： | 通过多基因累加方法选育8个小麦抗白粉病新品系分别与相应的单基因系杂交，18个杂交组合的F2代群体对小麦白粉菌15号小种的抗性反应结果表明：8个小麦新品系中，有2个品系分别累加了2个抗白粉病基因，其中“沈免20088”含有Pml2和Pm21，“沈免20134”含有Pm16和Pm21。另6个品系分别被导入了1个抗白粉病基因，其中“沈免20084”含有Pm12，“沈免20086”和“沈免20092”含Pm21，“沈免20091”、“沈免20140”和“沈免20144”含Pm16。这证实了利用常规选育方法进行主效基因累加是可行的。

| Abstract: | Eight new wheat lines obtained by multi-gene pyramiding method were crossed with corresponding single gene lines. The seedlings of F_2 progeny of eighteen cross combinations were inoculated with race no. 15 of Blumeria graminis f. sp. tritici. The results showed that two lines among the eight respectively contained two genes for powdery mildew resistance. SM20088 contained Pm12 and Pm21 , and SM20134 contained Pm16 and Pm21. Another six lines contained one gene each for powdery mildew resistance. SM20084 contained Pm12, SM20086 and SM20092 contained Pm21, and SM20091, SM20140 and SM20144 contained Pm16. The results indicated that multi-gene pyramiding by common breeding method was practicable |
