Abstract:
The present investigation was carried out to study the genetic diversity of Colocasia (Colocasia esculenta var. antiquorum (L.) Schott) involving 24 selected taro (including check) genotypes were evaluated at three locations during summer season of 2018 and 2019. The experiments were conducted at location viz., Jagdalpur, Bastar (L1), Kanker (L2) and Dantewada (L3) of Chhattisgarh in RBD with three replications. Observations were recorded for 16 quantitative traits which included leaf, petiole, corm, cormel and yield. The data was then subjected to D² analysis and was concluded from D² analysis that, the characters leaf area, corm weight plant^-1, cormel weight plant^-1 and yield plant^-1 contributed the maximum towards diversity. Studies in this direction are very less and can not to be generalized for every climatic condition and with other genetic materials. Hence, the information in a collection of some indigenous genotypes of taro in order to formulate a sound breeding plan for its improvement has been reviewed here.
