Genetic divergence in 30 indigenous and exotic collections of winged bean was studied by Mahalanobis D2 statistic for days to flowering, days to maturity, plant height, pods per plant, pod length and number of seeds per pod. Significant variations were recorded among the genotypes for all the characters. The genotypes were grouped into nine different clusters. The clustering pattern of the genotypes indicated that genetic diversity was uncorrelated with geographic diversity. IC95234 was the best genotype for early maturity, plant height and more number of pods per plant. Days to maturity and plant height contributed maximum towards the genetic divergence. Hybridization of IC95234 with either of IC112416, IC27885-1, EC 142654-4 and EC142667 for early maturity and inter crossing among EC038955, EC 178331, EC 178288 and IC95234 to get dwarf types have been suggested.
