近年来,随着“三系”杂交水稻的应用推广,育种工作者对于雄性不育细胞质在水稻杂种一代数量性状中的遗传效应,已开展多方面的研究。卢浩然等认为:“野败”胞质使杂种穗期延迟、分蘖增加,对千粒重、穗粒数及产量均呈负效应。庄尔铮等指出;不育胞质有利于提高生活力而对单株生产力具有明显的正效应,对株高、结实率有负效应。广西协作组研究认为:多数不育胞质对杂种一代的有效穗、每穗粒数、单株产量有正效应、对结实率、千粒重有负效应,产量的增加主要靠穗数增多。而罗孝和等则认为:不育胞质
In recent years, with the popularization and application of “three lines” hybrid rice, breeders have carried out various researches on the genetic effects of male sterile cytoplasm on the quantitative traits of rice hybrids. Lu Haoran and other think: “wild defeat” cytoplasmic hybrid panicle delay, tillering increased, the 1000-grain weight, grain number and yield were negative. Zhuang Erzheng pointed out that the sterile cytoplasm is conducive to improving the vitality of single plant productivity has a significant positive effect on plant height, seed setting rate negative effect. According to the study of Guangxi Collaborative Group, most of the sterile cytoplasm had positive effect on the effective panicles, grains per panicle and yield per plant of the hybrid generation, but had negative effect on the seed setting rate and 1000-grain weight. The increase of the yield mainly increased by the panicle number. And Luo Xiao and so that: sterile cytoplasm
