摘要： 三个高蛋白与三个高脂肪品种进行完全双列杂交，研究以籽仁重、蛋白质和脂肪含量为主的15个性状的配合力、遗传相关及杂种优势。结果表明：两种配合力的方差分析F值均达显著标准，但加性效应占主要优势，总配合力与杂种实际表现高度相关。郑71-3是高产高脂肪的理想亲本，奇科可作为高蛋白材料加以利用。在性状间相关中，蛋白与脂肪为显著负相关，但二者与籽仁产量呈弱的正、负相关，有利高产高油分和高产高蛋白品系的选育。花生杂种一代有明显优势，但营养生长性状、结实性状和脂肪含量趋向高亲，而出仁率、百仁重和蛋白含量趋向低亲。

Abstract: Statistic analysis on the combining ability and other genetic parameters of yield,protein,oil and other traits by Griffing’s method 4 with diallel crossed F1’s data of 3 high protein and 3 high oil parental varieties was made.Both variances of GCA and SCA are significant,but GCA is more important in all agronomic characters except yield and oil content.The correlation between protein and oil is significantly negative.But both of them are weakly correlated with yield.These seemed better for selecting high-yield lines with high content of oil or protein.There are evident heterosis in F1 hybrid of peanut.Most of their traits are inclined to the high parents,and hundrend seed weight,propein and meat content tend to their low parent.
