摘要
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。
The nuclues cytoplasm reciprocal interchange was carried out among CMS Shaan 2A、 Shaan 2B line、 CMS Pol A and Pol B line to get four CMS lines, which were used to carry out non complete double row cross with three restoring lines with different quality. The effects of male sterile nucleus cytoplasm on hybrid F 1 was studied and the stimilarity and difference of nucleus cytoplasm effects between Shaan 2A and Pol A system compared. The results showed that the agronomic characters controlled by additive and non additive genetic effects but the additive genetic effects are decisine.Nucleus cytoplasm effects of CMS lines had great influence on hybrid F 1. Male sterile genetic effects of nucleus were highly greater than that of cytoplasm. Nucleus and nucleus cytoplasm genetic effects of Shaan 2A significantly prior to that of Pol A and was also notably superior to that of Pol A in some agronomic characters.
