摘  要：
用表观收获指数和粒茎比不同的12个亲本配制11个组合,对其后代表观收获指数和粒茎比进行了研究。结果表明,大豆F_1代表观收获指数和粒茎比存在一定的杂种优势,其优势程度因组合而异。表观收获指数和粒茎比在F_2代均呈广泛分离,多数组合表现出超亲现象,其遗传属于数量性状遗传,无母体效应。F_2、F_3代,表观收获指数和粒茎比与中亲值相关显著。F_2代表观收获指数和粒茎比的广义遗传力分别平均为46.19％和37.47％。可将表观收获指数和粒茎比(?)入高产育种、高光效育种和株型育种的选择指标。

摘  要：
Genetics of soybean apparent harvest index and seed stem ratio of soybean were studied in this experiment. The results showed as follow:Heterosis of apparent harvest index and seed stem ratio appeared in F1 with different degree among crosses, and the values of the heterosis in average were 4. 0% and 0. 4% respectively. Apparent harvest index and seed stem ratio segregated widely in F2 with transgression in most of the crosses. Apparent harvest index and seed stem ratio were considered quantitatively inherited traits. Parents had a great affection to the progenies. The heritabilities of apparent harvest index and seed stem ratio estimated in this study were in average 46. 19% and 37. 47% respectively. These results indicate that the two indexes can be used in selection of high-yield breeding, high photosynthcitic rate breeding and plant-shape breeding.
