摘　　要：代表性是衡量核心种质的主要指标。本研究用 4 92 3份黄淮夏大豆种质以及从中选出的 4 2 8份黄淮夏大豆初选核心种质为实验材料 ,比较两者的农艺性状差异 ,目的是检测黄淮夏大豆初选核心种质对其总体的代表性 ,为大豆核心种质构建提供依据。结果表明 ,初选核心种质的种皮色、花色、茸毛色等 9个质量性状的不同表现型频率和 5个数量性状的平均数、标准差、方差、变异系数等参数 ,与黄淮夏大豆总体资源基本一致。 14个农艺性状Shannon weaver遗传多样性指数和Simpson遗传多样性指数的t测验 ,结果表明初选核心种质与总体差异不显著 ;对 9个质量性状频率分布进行χ2 测验 ,二者差异不显著 ,初步表明初选核心种质能够代表全部资源的遗传多样性。The representative of core collection is an important criteria for establishment of core collection. In this study, the entire collection and primary core collection of summer sowing soybeans in Huanghuai region of China were used as the materials, and 14 agronomic traits were compared. The aim was to test the representative of primary core collection to the entire collection. In quantitative distribution and frequency of the trait variation, the primary core collection and the entire collection were similar. The χ2 test for 9 discontinuous characters and the t test of both indexes for 14 morphological cha- racters did not reach significant level between the primary core collection and the entire collection, indicating the primary core collection may represent the entire collection.
