Abstract: 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 h² 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.
