The present experiment was performed with the objective of studying the morpho-physiological differences in seven mungbean genotypes namely, PDM 54 (V1), PDM39 (V2), IPM99-125 (V3), PDM11 (V4), IPM2-14 (V5), IPM2-3 (V6) and Pratap (V7) under water deficit environment. Some known parameters with their essential roles in drought stress like plant height, leaf no., leaf area, fresh and dry shoot and root biomass, leaf proline content and total chlorophyll were considered for the study under drought both in vegetative and reproductive stages. Results fed showing significant effects of water deficit conditions in all the seven mungbean genotypes. However, the detrimental effects of drought stress were more prominent in genotype IPM99-125 (V3), and left fewer changes in genotype Pratap (V7) which eventually depicts their differential behaviours under drought stress and the difference in their tolerance.
