An experiment was conducted with 9 colocasia [Colocasia esculenta var. antiquorom Schott.] genotypes to evaluate the estimate of genetic variability for different characters. The experiment was conducted using a Randomized Complete Block Design with three replications. The genetic parameters between yield and yield contributing characters of different colocasia genotypes were studied. Analysis of variance showed significant variation among the genotypes for all tested characters. The highest total yield was recorded in Indira Arvi-1 (29.54 t/ha.), which was followed by TTr 17-1 and TTr 17-12 (25.31 t/ha and 18.27 t/ha, respectively). Corm weight showed the highest genotypic and phenotypic variance (71.52 and 72.41 %) whereas no. of leaves showed the lowest ones (14.95 and 18.72 %). High value of heritability observed for all the characters except no of leaves per plant. Genetic advance as percent of mean reported highest for total yield, yield per plant, cormels weight and plant height. The genotypes exhibited a wide range of variability for all the traits studied.
