摘　　要：将不同来源的籼型不育细胞质育成的6种同核异质雄性不育系,分别与7个不同的恢复系杂交组配成42个F1杂交组合,在相同核背景下比较不同籼型败育胞质对水稻F1主要性状的影响。结果表明:不育细胞质的遗传效应对着粒密度、有效穗、千粒重、穗粒数、单株产量性状有显著或极显著的影响。不育细胞质效应之间存在差异,表现为同一不育细胞质在不同性状上效应的差异和同一不育细胞质与不同恢复系核之间的互作效应的差异。Forty-two combinations were obtained by crossing six CMS lines which were from diffrent indica male sterility cytoplasms and seven different restorer lines. Effects of different indica male sterility cytoplasms on major characters in Fl hybrids race were compared under isonuclear background. The results showed as follows ： The effects of male sterility cytoplasms were significant on characters of SD （ number of seed per ten centimeter）, PN （ number of panicle ）, GW （ 1 000-grain weight ）, SN （ spikelet number per panicle ）, GY （ grain yield per plant） , There were different effects among different male sterility cytoplasms, included the difference of effects on different characters with the same male sterility cytoplasm and the difference of effects of cytoplasmnuclear interaction with the same male sterility cytoplasm.
