Development and Utilization of the Restorer Lines Derived from Indica-Japonica Cross
-
摘要: 通过分析籼粳衍生恢复系选育与利用实践的成效及存在问题,认为:以优良籼稻恢复系为主体亲本,通过杂交导入粳稻亲缘,育成的籼型或偏籼型恢复系与籼型不育系有较好的亲和性及较强的配合力。恢复系材料的籼粳成分指数与其配制组合杂种的穗数、穗总粒数、千粒重间存在极显著相关,但与单株重的关系不显著;随着制恢材料粳稻成分增加,选育难度与效率将发生较大变化。Abstract: The achievement and problems on breeding and utilization of the restorer lines derived from indicajaponica cross were analyzed in this paper.We believed that main parent of excellent indica restorer lines were crossed with japonica.The results indicated that the bred indica or partial indica restorer lines were showed wide affinity and strong combining ability to the indica male sterile line.There was relationship to some extent between the components of indica-japonica of restorer line and the effective panicles per plant,filed spikelets per panicle,1000-grain weight,grain weight per plant of its combinations.With the increasing of composition of Japonica for the restorer lines,the difficulty and efficiency of breeding would be greatly changed.
