Thirty Desmodium gangeticum (L.) DC. accessions were evaluated for genetic variability, heritability and genetic advance for four yield attributing traits collected from different parts of India. The analysis of variance for mean squares for different characters was found to be highly significant for most of the characters under study except for lamina width, petiole length and internode length. Parameters of variability studies such as genotypic coefficient of variation, phenotypic coefficient of variation, heritability (broad sense) and expected genetic advance over mean were calculated and the data indicated that ample amount of variability exists in the available germplasm lines. High genotypic coefficient of variation was exhibited by pod fresh weight (70.24%), stem fresh weight (67.68%), leaf fresh weight (67.34%), stem dry weight (66.92%) and leaf dry weight (64.24%). Higher heritability was recorded by various characters like plant height (93.12%), tip height (85.65%), root girth (84.54%), stem girth (84.15%) and pod fresh weight (78.21%). High genetic advance was recorded in stem fresh weight (15.77%), stem dry weight (15.66%), leaf fresh weight (15.36%), leaf dry weight (14.75%) and tip height (14.03%). Thus, these germplasm lines could be utilized to improve root fresh weight, root dry weight and related characters in future breeding programme.
