摘  要:
采用常规遗传分析方法,将4个小麦新品系(种)和感病品种辽春10号配制5×5半双列杂交组合。用小麦白粉病菌15号生理小种的单孢菌系对各杂交组合的亲本、F1代、F2代群体和BF1代进行苗期抗病性鉴定。结果表明:沈免96、沈免20135、OB21和OB151这4个小麦新品系(种)对小麦白粉病菌15号生理小种的抗性各自都是由1个独立遗传的显性抗病基因控制;沈免96和沈免20135含有1个相同的抗白粉病基因,OB21和OB151各自含有1个不同抗白粉病基因,分别暂定名为WE9和WE1,WE1和WE9均不同于沈免96和沈免20135所含的相同抗白粉病基因。

摘  要:
By common analysis methods of classical genetics, the susceptible variety Liaochun10 and four resistant new lines/varieties were used for establishing one set of 5×5 hemi-diallel cross combinations. The seedling of parents, F_1, F_2 and BF_1 from the cross combinations were inoculated with race no. 15 of Blumeria graminis f. sp. tritici. The results showed that the four new lines, SM96, SM20135, OB21 and OB151, contained one independent dominant gene for resistance to powdery mildew respectively. SM96 and SM20135 contained the same one gene, OB21 contained one gene WE9(a temporary name), OB151 contained one gene WE1 (a temporary name), the gene WE9 was different from the gene WE1, either of the both was different from the gene contained in SM96 and SM20135.
