The present investigation was carried out in two different environments with aim to assess genetic variation among the genotypes for growth, yield attributes. The present investigation was comprised forty diverse genotypes of taro. The present study revealed that the significant differences for sixteen traits among genotypes of taro which indicated that the presence of adequate variability which could be harnessed for developing yield potential cultivars. The phenotypic and genotypic coefficients of variation were high for width of leaf, weight of corms per plant, number of cormels per plant and petiole length. Moderate to high heritability was evident for all the traits and was accompanied with high genetic advance for weight of corm, girth number of cormels, weight of cormels, of corm, length of leaf, width of leaf, and petiole length which suggests the role of additive gene action and thus, a high genetic gain is expected from selection of these traits. Moreover, high heritability along with moderate genetic advance for sheath length, height of plant, reveals the presence of additive and non-additive gene action simultaneously. On the other hand, dry matter showed low genetic advance along with high heritability that reflects the presence of non-additive action.
