A field experiment was carried out during the 2016 and 2017 main cropping seasons using a randomized complete block design with three replications in order to evaluate seven characteristics viz., days to 90% physiological maturity, plant height, number of pod per plant, number of seeds per pod, seed yield for two mung bean treatments under rain-fed conditions at Thakurgaon. Analysis of variance showed that, differences varietal was observed for traits studied except number of pods per plant. The variety MBM-656-51-2 mutant had better performance than the other variety with the highest seed yield (1.57 tha-1), while the lowest seed yield was obtained from BARI Moog 6 (1.52 tha-1). Thus, MBM-656-51-2 mutant is recommended as promising variety to the farmers of Thakurgaon areas.

Key words: Yield, mungbean, mutants.
