In this experiment 55 linseed genotypes were evaluated to determine genetic diversity by Mahalanobis D² statistics during rabi 2018-19 at the Department of Plant breeding and Genetics, Orissa University of Agriculture and Technology, Odisha India. It revealed that 55 genotypes were grouped into eleven clusters. Result envisaged that genotypes grouped within a particular cluster are more or less genetically similar. Genotypes grouped into cluster I were showed maximum intra-cluster diversity while maximum inter-cluster diversity was observed between cluster XI and V followed by cluster XI and X. So, it could be suggested that hybridization program involving genotypes from the farthest diverse clusters (Cluster XI and V and cluster XI and X) are likely to achieve wider and desirable heterotic recombinants or even transgressive segregants.
