Abstract

The present investigation was undertaken to understand the role of genotype and environmental interactions in the expression of various characters and stability of mungbean genotypes in eight environments. The significance of environmental component for all the characters except seed yield and protein content in pooled analysis indicated existence of substantial differences among the eight environments. Significant mean squares due to genotype x environment (G x E) interaction for all the character except protein content suggested that the genotypes showed considerable differential interaction with different environments. The polled deviation was highly significant for all the characters except protein content and 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 .The overall results of the stability analysis indicated that the genotypes Ganga 1 and PS 16 exhibited stability across environment indicating their adoption to spring and kharif seasons, rain-fed as well as  irrigated conditions. Thus, role of environment and G x E interactions must be taken into account while devising and implementing selection or breeding programmes in mungbean.
