Abstract:

An investigation was carried out to assess the genetic divergence in 26 seedling progenies of elephant foot yam utilising Mahalanobis D2 statistic. The experiment was carried out Horticultural Research station, Kovvur, DRYSRHU during 2018 in augumented block design with two checks. All the accessions were grouped into 6 clusters. The cluster II was the largest consisting of 15 accessions followed by cluster III with 5 accessions and cluster I with 3 accessions and cluster IV, V, VI had solitary accessions. Therefore, selection and intercrossing of genotypes involved in these clusters would be useful for inducing variability in the respective characters. Average intra and inter-cluster D2 values among 26 accessions revealed that cluster III recorded maximum intra cluster distance followed by cluster II indicating the existence of diverse genotypes in these clusters. While, inter cluster differences were maximum between cluster III and cluster V followed by I and VI, III and VI, III and IV, I and III and IV and VI indicating that the genotypes from these clusters can be selected for future breeding programme to produce heterotic hybrids.
