摘　　要：１２ 个菜用夏大豆品种的１２ 项粒荚性状和其他农艺性状的 Ｇ Ｃ Ｖ（ 变异系数） 、ｈ２（ 遗传率） 和 Ｇ Ｓ（ 遗传进度） 分析表明，粒荚性状的这些参数均高于其他各种性状。对粒荚性状的进一步分析表明在鲜、干状态下，荚皮面积和重量的遗传参数高于百粒重和荚重。相关系数表明粒荚性状间各性状关系密切，荚皮面积大，荚皮的重量也重（０ ．９ ＊ ＊ ） ，百粒重则大（０ ．８８ ＊ ＊ ） ，荚的重量就重（０ ．８９ ＊ ＊ ） 。粒荚性状与产量表现为不显著的正相关。应当注重菜用大豆的粒荚性状特别是荚皮性状的潜力。The genetic coefficient of variation(GCV),heritability(h2) and genetic speed(GS) of 12 seed pod characters and other agronomic characters in 12 varieties of summer vegetable soybean have been studied. The results showed the parameter of seed pod characters was higher of other agronomic characters. Further analysis of these characters indicated the genetic parameter of pod-rind area and weight was higher of 100-seed weight and pod weight under fresh or dry conditions. The correlation coeffient showed a close relation among all seed pod characters. The bigger the area,the greater the pod-rind weight(0.9) and the 100-seed weight(0.88),hence the pod weight(0.89). The presence between seed pod characters and the yield revealed a positive correlation. It was suggested that attention showld be paid to the potential of seed pod characters,especially of pod-rind characters in vegetable soybean.
