摘要
以高产、高蛋白、高脂肪三类5亲本轮配杂交的F_1代资料,按Griffing方法模型1,对5种主要农艺性状分析了正反交效应和配合力。全部10组合平均各性状正反交差异均不显著,不存在母体效应。配合力分析表明:不同类亲本性状水平与值大小关系密切,值与值有一定关系。优质性状、产量性状与籽粒外观品质性状的配合力存在符合育种要求的互补作用。优质亲本的其它农艺性状水平也很重要。
The reciprocal cross effect and combining ability of F1 's date of 20 crosses with 5 parental varieties diallel crossing by Griffing's method 1 model 1 were analysed. No significance of 5 characters between reciprocal and normal cross in mean of all ten crosses. Protein and oil content expressed significant difference between reciprocal and nromal cross in individual cross, but positive and negative effect were half and half for number of cross, generally. This is no indication of maternal effect. Analysis of combining ability shows: 1. It is closerelationship between characteristic level and estimate of gi among parental systems. 2. In a certain sense, there are close relation between estimate of sij and gi. 3. The specific combining ability of protein content, seed weight per plant and percent of normal seed exist complementary effect in cross combination.
