| 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，细胞质遗传效应在一些农艺性状上也显著优于波里马A。 |

| Abstract: |
| The nuclues-cytoplasm reciprocal interchange was carried out among CMS Shaan 2A、Shaan 2B-line、CMS PolA and PolB-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 F1 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 F1.Male sterile genetic effects of nucleuswere highly greater than that of cytoplasm. Nucleus and nucleus-cytoplasm genetic effects of Shaan 2A significantly prior to that of PolA and was also notably superior to that of PolA in some agronomic characters. |
