TOPSIS method was used to analyze and evaluate main varieties（lines） of mungbean. TOPSIS method can sort the distance between different trait indexes of a target group and ideal solution and negative ideal solution, and evaluate the pros and cons based on the proximity of multiple evaluation indexes to the ideal goal. It is a common method in multi-objective decision analysis. The TOPSIS method was introduced into the evaluation and judgment of crop varieties, and was used as an auxiliary analysis method for the comparison of mung bean varieties（lines）,which opened up a new way for the comprehensive evaluation of mung bean varieties. The agronomic, economic and quality traits of mung bean were homogenized and normalized, and TOPSIS method was used to evaluate the main cultivars of mung bean, and then combined with the actual field performance of each cultivar to conduct comprehensive evaluation, providing theoretical and practical basis for variety promotion. Through the identification and evaluation of 13 mung bean varieties（lines）, 4 varieties（lines） including JL2012-1, Bailv8, Jilv10 and JL200906 were selected in this paper. These varieties（lines） had high yield, lodging resistance, disease resistance, full grain and good commodity property, and could be widely spread after demonstration.
