The present investigation was undertaken to understand the role of genotype and environmental interactions in the expression of various characters and stability of Mung bean genotypes in four environments. The signifi cance of environmental component for all the characters in pooled analysis indicated existence of substantial diff erences among the four environments. Significant mean squares due to Genotype×Environment (G×E) interaction for all the characters except number of seed pods and 100 seed weight suggested that the genotypes showed considerable diff erential interaction with diff erent environments. The pooled deviation was highly signifi cant for all the characters except number of seed per pod 100 seed weight indicating that the response of genotypes taken for this study was not predictable and non-liner component played an important role in the development of the characters. Th e overall results of the stability across environment indicating their adaptation to rainfed as well as irrigated conditions. Thus, role of environment and G×E interactions must be taken into account while devising implementing selection or breeding programs in Mung bean.
