大豆育种涉及的主要农艺性状多属数量性状,易受环境条件的影响,造成选择上的困难。研究分析大豆杂交材料农艺性状的遗传变异程度,遗传给后代的程度和环境条件影响的程度对于早期世代进行可靠的有预见性的选择是有帮助的。 Weiss等(1947,1949)研究了17个大豆杂交组合农艺性状在各世代间关系后认为,
The main agronomic traits involved in soybean breeding are mostly quantitative traits, susceptible to environmental conditions, resulting in the selection of difficulties. Studying and analyzing the degree of genetic variation in the agronomic traits of soybean hybrids, the extent of their inheritance to future generations and the extent to which they affect the environmental conditions are helpful for a reliable and predictive selection of early generations. Weiss et al. (1947, 1949) studied the agronomic traits of 17 soybean cross combinations after the relationship between generations,
