分析了高抗白背飞虱、对白背飞虱的抗性表现为拒取食性和杀卵作用的中国粳稻春江06和感虫籼稻品种TN1正反交获得的F1和F2代拒取食性和杀卵作用的遗传方式.所有的F1稻株都具有拒取食和杀卵作用.两种抗性在F2代中以3∶1的抗感比例独立分离. 具有拒取食和杀卵抗性的不同组合的4种表现型以9∶3∶3∶1分离.表型分离说明春江06中的拒取食性和杀卵抗性分别受一个显性基因控制.采用常规的杂交方法可以容易地将春江06中的拒取食抗性导入日本粳稻品种日本晴、北陆-153和越光中.

Whitebacked planthopper (WBPH) resistance in Chinese japonica rice Chunjiang 06 (CJ-06) was expressed by sucking inhibitory and ovicidal traits. Modes of inheritance of both these traits were analyzed by using F1 and F2 progenies from reciprocal crosses between CJ-06 and a susceptible indica variety TN1. All the F1 progeny were resistant, having both the sucking inhibitory and ovicidal traits. The two resistant traits of F2 progeny segregated independently at the ratio of 3 (resistant) ∶ 1 (susceptible). Four phenotypes with differential combinations of sucking inhibitory and ovicidal traits segregated into the ratio of 9 ∶ 3 ∶ 3 ∶ 1, indicated that respective single dominant genes independently governed both the sucking inhibitory and ovicidal traits in CJ-06. The sucking inhibitory trait in CJ-06 could easily be introduced into Japanese japonica rice, Nihonbare, Hokuriku-153 and Koshihikari by conventional crossing.
