| 摘 要： | 用广谱感瘟籼型品种Ｂ４０分别与３个持久抗瘟性籼型品种Ｔｅｔｅｐ、湘资３１５０和谷梅２号杂交。３个组合的Ｆ１和Ｆ２及双亲在苗期用Ｚｈ-２-１菌株喷雾接种。结果表明，Ｔｅｔｅｐ、谷梅２号和湘资３１５０均由２对显性基因控制对试验菌株的抗性，其中前２个品种的基因间表现重叠效应，后１个品种的基因间表现抑制效应。

| Abstract: | Tetep, Xiangzi 3150 and
Gumei 2, 3 indica varieties with durable resistance to rice blast, were crossed to highly
suceptible indica variety B40, respectively. The parents, F1 and F2 seedlings were inoculated
with isolale Zh21 of Pyricularia grisea by spraying. The results showed that Tetep and Gurmei
2 had two dominant genes with duplicate effect for resistance to the isolate, respectively.
Xiangzi 3150 had also two dominant genes with inhibiting effect for resistance to it. |
