摘要
本文通过参试杂交水稻10个性状的方差分析和不育系、恢复系一般配合力、特殊配合力估算及配合力总效应值比较,分析了新恢复系绵恢501、绵恢502与明恢63的异同,结果表明,三个恢复系虽然在多数性状上存在着显著差异,但由于它们各自在产量三要素:穗、粒、重上的性状互补,反应在单株粒重上,三者之间差异甚小,结实率、单株粒重的一般配合力效应值和配合力总效应值,三个恢复系非常按近,表明它们具有相似的恢复力和生产潜力。
This paper's writers analysed the variance of 10 characters of experimented hybrid rice; evaluated the general and specific combining ability of male sterile line and restorer line; contrasted the total effect of combining ability and compared Similarities and differences among mian hui 501. mian hui 502 and Min hui 63. It was Showed differnce on the grain weight per plant of three restorer lines was less, though there were remarkable differences on most characters, they havecom plementation of characters on their panicle number per plant, filled grains per panicleand 1000-grain-weight. The general combining ability of seed set rate and grain weight per plant, as well as total effect of combining ability, were very approximate, So their restorer ability and yield potential are similar.
