Abstract: In this study, we collected the six popular adzuki bean varieties of sanjiang plain which are baoqinghong, nonganhong, zhenzhuhong, tianjinhong, dahongpao to analyze the production trait and quality characters index. The results showed that the plant height, node numbers of main stem and numbers of branches of nonganhong were all best. Pod number per plant and grain number per pod of nonganhong and tianjinhong were the most: 8.6 and 8.8 respectively. Zhenzhuhong seeds color were the brightest, but 100-grain weight were the lowest and nonganhong were the highest reach to 19.6 g. The yield per unit area of nonganhong and zhenzhuhong were much higher than other varieties. The content of protein in nonganhong and amylopectin content in baoqinghong and nonganhong were all the highest. Starch granule size in nonganhong and zhenzhuhong were significantly greater than others, and the production rate of sweetened bean paste were up to 69.60% and 69.63% severally. According to the comprehensive index, 4 antioxidant enzyme activities were ranked as nonganhong >baoqinghong>zhenzhuhong>dahongpao>longkenhong 2>tianjinhong. These results suggest that nonganhong and zhenzhuhong were suitable to plant in sanjiang plain.
