摘要/Abstract

摘要： 利用大豆不同杂交类型的23个组合，研究了亲子代及F1、F2和F3代间遗传变异的相互关系。结果显示，高含量亲本对后代表现有部分显性作用。多数组合蛋白质含量、油分含量在F1、F2和F3世代的平均数介于两亲之间，偏高和偏低组合几乎各占一半，优势强度在组合间有一定差异，故合理选择亲本有可能获得比两亲表现更优良的组合。两亲

Abstract: F1, F2 and F3 generations of twenty-three crosses among nine parental cultivars with different protein, oil contents were used to study the relations of genetic variability between offsprings and parents, and among generations. The results indicated that the mean mid-parent heterosis of protein
