摘要： 本试验利用三个不同结荚习性的栽培大豆(G.max)做母本,分别与三个半野生大豆(G.graeilis)按NCⅡ设计配制的9个杂交组合,估测了F_1、F_2代主要农艺性状的优势指数;F_2代主要农艺性状的平均数、变幅、遗传变异系数、遗传力和预期遗传进度。试验结果表明:F_1代除百粒重、主茎有效节数以外,其余性状均有明显的杂种优势;F_2代除有

Abstract: Progenies from 9 crosses between three cultivated soybean (G.max) of different terminaltypes and three semi--wild soybean (G.gracilis) were used to study the heterosis indices of ma-jor agronomic characters in F_1 and F_2 generations, and to investigate the means, ranges,GCV. s, heritabilities and g
