The Himalayan foothills region of India is rich in the genetic diversity of okra which is yet to be explored for its genetic divergence. To envisage the genetic diversity of this un-explored varietal collection, the genetic divergence among 25 genotypes of okra was estimated using Mahalanobis D2 statistic. The indigenous and exotic lines were grouped into 6 clusters using Tocher’s methods. Results revealed that a higher number of genotypes were recorded under Cluster I (19) and cluster IV (2) while cluster II, III, V and VI were mono-genotypic. A higher intra- cluster distance was observed between cluster I (13.42) & cluster IV (7.47), whereas, a higher inter-cluster distance was found between cluster III and cluster VI (111.03). The traits viz, YVMV incidence (44.67 %) was contributing the highest towards the total genetic divergence. The present study revealed the detailed genetic divergence for different yield-attributing traits in okra. This study presents a strong basis for the selection and evolving of better recombinants for hybridization and quality improvement programme. This research bear utility in the form of germplasm conservation and crop improvement for selected indigenous/exotic genotypes grown in Himalayan foothills.
