摘要/Abstract

摘要： 高产品种诸多经济性状的量值都有不同程度的增长,其中以节荚数和粒茎比值增量最大。其形态性状株型向矮壮紧凑型变迁。粒茎比值高、茎重适宜、光效高才是高产品种的重要特点。 F_2代粒茎比值呈连续遗传变异,组合发生正负向超亲变异机率较高为60％,个体发生正负向超亲变异机率极低,其中正向仅0.98％。亲本对F_2代粒茎比值有较

In these characters, the increment of pods/per node and ratio of seeds to stemare the largest ones. The morphological characters and plant type of high yielding varie-ties change to dwarf, strong and compact t
