The aim of this research is to evaluate the genetic characteristics of 9 introduced mung bean varieties, thereby creating a database of agronomic characteristics, as a basis for future studies. The experiment was conducted from January to April at the net house of the School of Agriculture and the Laboratory of Molecular Biology, Institute of Food and Biotechnology, Can Tho University, Vietnam. The experiment was arranged in a completely randomized design with 1 factor, 9 treatments and 4 repetitions, in which the Taichung variety was selected as the control variety. The results showed that the mung bean varieties had two harvests and grew well. The seed shape of introduced varieties was diverse with the highest Shannon index (1.08). Besides, mung bean DNA was amplified with 3 sets of SSR primers (CEDG026, CEDG232, CEDG037) of linkage groups of 2, 4, and 6, respectively. The results showed that all 3 primer pairs appeared in monomorphic bands. The broad-sense heritability of traits varied from 0.02% to 63.60% in first harvest and 33.32% to 78.41% in second harvest. Moreover, the correlation coefficient results showed a strong positive relationship between the yield and the number of pods per plant. Based on important agronomic traits including the number of pods per plant, 1000 seed weight, growth time and yield, 2 promising mung bean varieties were initially selected (VC 6494-986-S7 and VC 6518-50), of which VC 6494-986-S7 had superior yield compared to the control variety, used as a material for further studies.
