21 mung bean varieties were used to analyse seed physical characteristics such as seed coat color, seed coat proportion,100-grain weight and seed physiological characteristics such as biological yield variation during germination, water absorption rate ,as well as the sprout traits such as mung-bean sprouts yield, morphological characteristics of sprouts and sensory quality of sprouts, This study also analysed the correlation among physical, physiological characteristics and the characteristics of sprouts. The results showed that the range of the indexes (Sprouts yield, hypocotyl diameter and hypocotyl length) of 21 mung bean materials 111.7-143.2,7.21-11.79 and 0.245-0.353,respectively. There was no significant correlation between seed coat color and biological yield, hypocotyl rough , hypocotyl length.There was significantly correlation between seed coat color and thousand-grain weight（P<0.05）. 100-grain weight and biological yield had significant negative correlate. Hypocotyl diameter and biological yield had significantl negative correlate（P<0.05）. Based on the study, the indexes which were suitable for evaluating mung bean sprout traits were selected，they were sprouts yield, hypocotyl diameter and hypocotyl length. MB01,MB07,MB19 and MB45 were selected which had good sprouts traits .
