Stability analysis in mungbean (Vigna radiata (L.) Wilczek)

The present investigation was undertaken to understand the role of genotype and environmental interactions in expression of various characters and stability of mungbean genotypes in three environments. The significance of environment (linear) component for all the characters in pooled analysis indicated existence of substantial differences among the three environments in respect to their influence on expression of six characters in 80 mungbean genotypes. Significant mean squares due to genotype x environment (G x E) interaction for all the character suggested that the genotypes showed considerable differential interaction with different environments. Thus, role of environment and G x E interactions must be taken into account while devising and implementing selection or breeding programmes in mungbean.
