A half diallel analysis involving nine cultivars showed that additive as well as non-additive gene effects were important for the inheritance of seed yield per plant, 100-seed weights, protein content and potassium per cent. For remaining traits non-additive genetic components were important. Overdominance was observed for all traits except for 100-seed weight, which expressed partial dominance. Parents PMR-T10, EC21857, EC109182, T163 and EC109189 were good general combiners for seed yield, seed weight and quality traits. In general there was a good relationship between per se performance and the gca effects of the parents for all traits. Cross combinations such as LMR8 x EC109182,LMR8 x PMR-T10,LMR8 x EC21857,PMRT10 x EC21857 and P23 x EC21857 were found promising. The seed yield was positively correlated with other quality traits. Protein had a positive correlation with methionine and phosphorus. All the values of correlation co-efficients were non-significant except for yield with potassium, 100-seed weight and protein with methionine, indicating that yield and quality attributes can be improved simultaneously by simple selection procedures.
九个品种的半双列分析表明，对于单株种子产量、百粒重、蛋白质含量和钾百分率的遗传，加性和非加性基因效应都很重要。对于其余性状，非加性遗传成分很重要。除了百粒重表现部分显性外，所有性状都观察到超显性。PMR-T10、EC21857、EC109182、T163 和 EC109189 等亲本是单株产量、种子重量和品质性状的良好一般配合力亲本。一般来说，所有性状的自身表现与亲本的一般配合力效应之间存在良好的关系。LMR8 x EC109182、LMR8 x PMR-T10、LMR8 x EC21857、PMRT10 x EC21857 和 P23 x EC21857 等杂交组合具有很大的潜力。种子产量与其他品质性状呈正相关。蛋白质与蛋氨酸和磷呈正相关。除了产量与钾、百粒重和蛋白质与蛋氨酸呈正相关外，所有相关系数值均不显著，这表明通过简单的选择程序可以同时提高产量和品质特性。
