Information on genetic variability was obtained for 12 characters in 36 accessions of arvi (Colocasia esculenta var. antiquorum) grown at Kumarganj, Faizabad, India during 1998–99. Significant differences occurred between the genotypes for the characters studied. The highest phenotypic and genotypic coefficients of variation occurred for weight of cormels per plant followed by number of cormels per plant and weight of corms per plant. High heritability estimates along with high genetic advance were obtained for weight of corms per plant, number of cormels per plant, weight of cormels per plant and dry matter content of cormels, which indicated the scope of individual plant selection based on these characters for the genetic improvement of arvi.
