摘 要 ：大豆品种间杂种优势是普遍存在的,不同性状有明显差异。在研究的19个性状中,单株粒重的平均优势最强,其次是叶柄干重。并按如下顺序递减:单株荚数,单株粒数,叶面积系数,单株根干重,总干重,叶片干重,分枝数,侧根数,主茎干重,株高,百粒重,经济系数,主茎节数,出苗-开花日数。开花-成熟日数和单位叶面积干重表现为低于双亲平均值

Abstract:The materials used in the present studies were originated from 17crosses which were made in 1978.The experimental results pointed outthat heterosis,while common in F₁ inter-varietal soybean hybrids,va-ried considerably with different characteristics.Among the 19 characteristics studied th
