Abstract

Mahalanobis’s D2 statistics was used to study genetic divergence for nineteen characters in a collection of forty four brinjal genotypes. The 44 genotypes of brinjal were grouped into seven clusters on the basis of relative magnitude of D2 values. The maximum inter cluster distance was observed between clusters III and VII, while minimum was recorded between clusters III and IV. The maximum contribution towards divergence was from yield per plant and number of fruits per cluster. Considering cluster means and genetic distances, selection of parents from clusters III and VII for hybridization programme would help in achieving novel recombinants.
