选用50份黑龙江省大豆品种的株高、底荚高、单株荚数、单株粒数、百粒重等主要农艺性状进行多样性分析及聚类分析。结果表明：黑龙江省的大豆品种底荚数、单株荚数、单株粒数的变异幅度较大，株高、百粒重等性状的变异幅度较小；各积温带的品种性状变异幅度存在很大差异，第四积温带的大豆品种性状存在丰富的变异类型；通过聚类分析将供试品种分为3个组群，第Ⅲ组的大豆品种产量相关性状表现优于其他组群的大豆品种。

50 soybeans cultivars of Heilongjiang were selected,the main agronomic characters,such as plant height,height of base pod,pods per plant,seeds per plant,100-seed weight and so on were analyzed. The result showed range of base pod height,pods per plant,seeds per plant were wide,but plant height and 100-seed weight were narrow. Different characters′range are different in different ecological zone,especially the fourth ecological zone have rich variation type. The soybean cultivars were classified into 3 groups,and the yield related characters of groupⅢare better than other groups.
