摘　　要：本文对北京地区生育期在100d左右的8个大豆M4家系的146个品系进行农艺性状的比较和遗传参数的分析。结果表明:(1)产量、品质性状明显高于对照的品系主要集中在中黄11、中黄17、中品58023个M4品种中。(2)遗传力>60%的农艺性状分别为结荚高度、单株粒数、单株荚数、R8、全生育期。(3)相对遗传进度的大小依次为单株荚数、全生育期、主茎分枝数、R1、结荚高度。(4)遗传变异系数>25%的为单株荚数、R7、R8、主茎分枝数。The analyses on genetic parameter was agronomic character of 146 soybean M4 whose the bearing term was less than 100 clays chosen from 8 soybean varieties. The results indicated： （ 1 ） Yield and quality proterties is significant higher than the varietie that compared major concentration in zhongzuo92 - 121, zhongpin5802, zhongzuo976 three kinds in. （2）The agronomic characters whose heredity 〉 60% were the height of lowest legume, the number of eaulishodes, Rs , the amount of legumes per plant and whole bearing term. （3） The ordinal rate of relative heredity progress were the amount of legumes of per plant, whole breeding term, the number of caulis＇divarications, RI, the height of lowest legume. （4） Whose genetic variation parameter 〉 25% were the amount of legumes per plant, R7, R8, the number of caulis＇divarications.
