Abstract: Abstract: To solve efficient breeding and high yield of mung bean, we studied on nine major agronomic traits and yield of ten varieties with grey correlation evaluation method. The results showed that correlation of different agronomic characters and yields were: pods per plant> 100-seed weight> node numbers of main stem > plant height> pod grains> growth period> blooming stage> branche number of main stem > pod length. Pods per plant has the largest effect on the yields of mung bean, then the larger is 100-seed weight, and the length of pod has the smallest effect on yields. When high yield variety of new MungBeen was selected, the character of Number of pods per and hundred-grain weight plant should be taken into consideration first, then to comprehensively consider the rest of characters.
