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11.63 g，变幅为5.28~24.47 g，品种间差异达极显著；筛选出百粒重大于17 g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（h2）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=38.076 17+1.770 62x。

Abstract: 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 17g were obtained.The mean of size of seed starch granules of all 474 shares of adzuki bean was 57.71μm 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=(38.07617)+(1.77062)x.
