摘 要 ：本文通过对大豆主要农艺性状的世代平均值分析,估算了 a、d、aa、ad 和 dd 各类基因效应。结果表明:主茎节数、分枝数、不稔荚和百粒重以加性基因效应为主,加性率均在50%以上。有效荚数、单株粒数和单株粒重的显性效应最重要,显性率分别是59.97%、64.73%和49.79%。所研究的9个性状均表现较高的上位效应,上位率在13.19%(单株粒

Abstract:Generation mean analysis was conducted for a number of important agronomic charac-ters of soybean to evaluate the roles played by the different gene effects.Data from the P1,P2,F1,F2,B1,and B2 generations of 5 combinations were used and estimates of gene ef-fects,including a,d,aa,ad,and dd,with thei
