The present investigation was conducted to elicit information on different genetic variability parameters for 11 morphological and 6 drought tolerance related physiological traits viz., days to 50% flowering, days to maturity, plant height, number of branches per plant, number of pods per plant, pod length, seeds per pod, 100-seed weight, biological yield per plant, grain yield per plant, harvest index, relative water content, leaf area per plant, chlorophyll content, leaf thickness, seedling vigour index and germination stress index in different types of clusterbean genotypes. Mean squares due to genotypes revealed a wide range of variability and significant differences among all genotypes for all the characters under study. The range of variability was maximum for leaf area per plant followed by seedling vigour index, germination stress index, chlorophyll content and plant height. High genetic gain along with high heritability and moderate genotypic coefficient of variation was recorded for germination stress index, leaf area per plant and seedling vigour index, while high genetic gain with moderate heritability and genotypic coefficient of variation was recorded for number of pods per plant, grain yield per plant and biological yield per plant.
