摘要： 分析了城特232、嘉23和浙湖8号等3个粳稻品种对稻瘟病菌ZD1、ZE1和ZF1及白叶枯病菌8810-1的抗性遗传,结果表明,3个抗病亲本对ZD1、和ZF1的抗性都带有2对显性重复基因。等位性测定表明其中至少有1对是等位的，对ZE1小种的抗性均受1对显性基因控制，等位性分析三者的抗性基因各不相同。城特232和嘉23对白叶枯病抗性是由1对显性基因控制，而浙湖8号为2对显性互补基因控制。等位性测定表明城特232和嘉23的1对基因是等位的，但与浙湖8号的2对抗性基因是不等位的。推断了抗病亲本的可能的抗性基因。

Abstract: Inheritance on resistance of three japonica varieties Cheng-Te 232, Jia 23 and Zhe-Hu 8 to blast races ZD1, ZE1 and ZF1 and 8810-1 isolate of bacterial blight was analysed. Three resistant parents had two dominant duplicate resistant genes to ZD1 and ZF1 races and according to allelism test at least one of them was allelic. They had different single dominant gene respectively to ZE1 race. The bacterial blight resistance of Cheng-Te 232 and Jia 23 was controlled by a single dominant gene, and two dominant complementary genes for Zhe-Hu 8.Allelism test indicated the genes of Cheng-Te 232 and Jia 23 were allelic and nonallelic to those of Zhe-Hu 8.These resistant genes of diseases of resistant parents were deduced.And the utilization of three resistant parents in disease resistance breeding was discussed.
