用细胞质雄性不育系陕２Ａ、保持系陕２Ｂ和细胞质雄性不育系波里马Ａ、保持系波里Ｂ，进行核质置换，再与３个不同品质的恢复系进行不完全双列杂交，研究不育核质效应对杂种Ｆ１的影响，比较陕２Ａ和波里马Ａ核质效应的异同。结果表明：杂种Ｆ１的农艺性状是由加性效应和非加性效应控制的，而以加性效应为主；雄性不育的核质效果对杂种Ｆ１有重要影响；雄性不育细胞核的遗传效应极显著地大于细胞质；陕２Ａ的细胞核和核质遗传效应极显著地优于波里马Ａ，细胞质遗传效应在一些农艺性状上也显著优于波里马Ａ
The cytoplasmic male sterile line Shaan 2A was used to maintain Shanbian 2B and cytoplasmic male sterile line Polima A. The maintainer line B was used for nuclear replacement and then with incomplete reciprocal diallel cross with three restorer lines of different quality , To study the effect of sterility nuclear effect on hybrid F1 and to compare the similarities and differences of A nuclear effects between Shan 2A and Polima A. The results showed that the agronomic traits of hybrid F1 were controlled by both additive and non-additive effects and additive effects. The effect of male sterility on the F1 hybrid was significant. The genetic effect of the male sterile nucleus Significantly greater than the cytoplasm; Shaanxi 2A nuclear and cytoplasmic genetic effects extremely significantly superior to Polima A, cytoplasmic genetic effects in some agronomic traits is also significantly better than Polima A
