用3套包含3种不同雄性不育细胞质的9个不育系，与8个恢复力具有明显差异的恢复系组成9×8不完全双列杂交，按再裂区设计分析了胞质效应。结果表明，胞质效应具有明显的多样性，它既表现为不同胞质对同一性状和同一胞质对不同性状的效应存在差异;也表现为胞质效应组成的多样性，即胞质效应由胞质的一般配合力、胞质与保持系结合的特殊的一般配合力、胞质与恢复系互作及胞质与保持系、恢复系二级互作的特殊配合力四个组分中的一个或多个组成。野败型、D型和K型三种胞质对杂种一代千粒重的效应包含上述四个组分;对穗总粒数的效应只含胞质与保持系、恢复系互作的特殊配合力;对其余各性状的效应无明显差异。提出选育类似于多系品种的多胞质杂交稻的设想。
Nine cytoplasmic effects were analyzed by 9 sets of 9 sterile lines containing 3 different male sterile cytoplasms and 9 × 8 incomplete diallels with 8 restorer lines with obvious difference. The results showed that the cytoplasmic effect has obvious diversity. It shows that different cytoplasm have the same effect on the same trait and the same cytoplasm to different traits, but also shows the diversity of the cytoplasmic composition, that is, the cytoplasmic effect is caused by The general combining ability of cytoplasm, the special general combining ability of cytoplasm and maintainer, the interaction between cytoplasm and restorer and cytoplasm and maintainer, and the special combining ability of restorer and secondary interaction One or more components. The effects of wild-type, D-type and K-type cytoplasm on 1000-grain weight of hybrid generation contained the above four components; the effect on total grain number of panicles included only cytoplasm and maintainer, and the special combining ability of restoring lines; No significant difference was observed in the other traits. The idea of breeding polycystic hybrid rice which is similar to the multi-line variety was proposed.
