通过 4个不育系和 5个恢复系所配 2 0个组合 10个性状的方差分析和不育系、恢复系的一般配合力及特殊配合力相对效应值的比较 ,表明籼型新不育系红矮A在千粒重、单株粒重、穗长、结实率等性状上的配合力明显高于珍汕 97A ,其它性状与珍汕 97A具有相似的配合力。绵恢 2 0 0 9穗着粒、穗实粒、单株粒重等性状的配合力明显高于明恢 63,结实率和全生育期与明恢 63具有相似的配合力。
Through the analysis of variance and sterile lines of 20 traits with 20 combinations of 4 sterile lines and 5 restorer lines, the comparison of the general combining ability and the relative combining value of the special combining ability showed that the indica new sterile The combining ability of Hongzao A with grain weight per plant, grain weight per plant, ear length, seed setting rate and other traits was significantly higher than that of Zhenshan 97A. Other traits had similar combining ability with Zhenshan 97A. The combining ability of Mianhuo 2 0 0 9 panicle grain, panicle seed, grain weight per plant and other traits was significantly higher than that of Minghui 63, and the seed setting rate and the whole growth period had the same combining ability with Minghui 63.
