摘　　要：对我国主产区红小豆地方品种资源中随机抽取的335份、日本25份和韩国2份材料子粒色泽和出沙率进行了鉴定评价.结果表明,红小豆粒色红度值(a*)平均为19.71,粒色偏灰暗,变幅为13.0～26.0;黄度值(b*)平均为9.58,变幅为5.2～16.8;亮度值(L*)平均为26.47,变幅为18.1～34.0;出沙率平均值为68.08%,变幅为61.90%～75.98%;地区间显示出明显差异.a*、b*、L*和出沙率4个性状均具有较高的遗传变异,但粒色a*、b*和L*的广义遗传力值h2较高,出沙率的广义遗传力较低.筛选出红度值超过24.0的种质资源6份,筛选出亮度值超过30.0的种质资源16份,筛选出黄度值超过13.0的种质资源8份,筛选出出沙率高于73.5%资源8份.The seed coat color and the produce sweetened bean paste rate are the importance features to determine the character of commodity of adzuki beans. In this paper, 335 shares of adzuki beans germplasm resources from major production areas in China,25 shares of Japan＇s and 2 shares of Korea＇s were selected at random,and its seed coat color and the produce sweetened bean paste rate were appraised. The results indicated that the mean of degree of red value（a^＊） was 19.71, it＇s gray somewhat, and the range was 13.0 - 26.0. The mean of degree of yellow value（b^＊） was 9.58, and the range was 5.2 - 16.8; The mean of degree of brightness value（ L^＊） was 26.47, and the range was 18.1 - 34.0; The mean of produce sweetened bean paste rate was 68.08%, and the range was 61.90% - 75.98% ; There were obvious differences between areas. Each of the 4 characters of a^＊ , b^＊ , L^＊ and the produce sweetened bean paste rate was of higher genetic variation. The generalized habitability values h^2 of a^＊ , b^＊ and L^＊ of seed color were high but the generalized habitability of produce sweetened bean paste rate was comparatively low. The germplasm resources of 6 shares of degree of red value exceeding 24.0,16 shares of degree of brightness value exceeding 30.0,8 shares of degree of yellow value exceeding 13.0 and 8 shares of produce sweetened bean paste rate exceeding 73.5% were obtained by selection.
