摘　　要：对来源于我国主产区的446份、日本26份和韩国2份小豆种质资源的百粒重及淀粉粒大小进行了鉴定。结果表明，我国小豆种质资源群体平均百粒重为11．63g，变幅为5．28-24．47g，品种间差异达极显著；筛选出百粒重大于17g的大粒和特大粒种质资源7份；474份小豆子粒的淀粉粒大小平均为57．71μm，变幅为46．21-83．46μm，广义遗传力（h^2）为58．99％，属中等遗传力；小豆淀粉粒的大小（y）与子粒百粒重（x）具有显著的回归关系：Y=38．07617＋1．77062x。100-seed weight and size of starch granules of 446, 26 and 2 shares of adzuki bean germplasm resources from major production areas in China, Japan and Korea separately were appraised in this paper. The results indicated that ： The average value of 100-seed weight of adzuki bean germplasm resources in China was 11.63 g within the range of 5.28 - 24.47 g, and the difference between varieties was extremely significant; 7 shares of germplasm resources of big seed or especially big seed which 100-seed was exceeded 17 g were obtained .The mean of size of seed starch granules of all 474 shares of adzuki bean was 57.71 μm within the range of 46.21 -83.46 μm,and its generalized habitability（h2） was 58.99% as middle value. There was significant regression relation between size of seed starch granules （y）and 100-seed weight （x）, and its regression equation was y = 38.076 17 ＋ 1.770 62x.
