Studies in Brinjal Genotypes: Part II-Genetic Divergence

Abstract

Mahalanobis's D2 statistics was used to study genetic divergence for 20 characters in a collection of 90 brinjal genotypes. These 90 genotypes were grouped into 7 clusters on the basis of relative magnitude of D2 values. The maximum contribution towards the total genetic divergence was from yield per plant. It has been observed that no close correspondence is evident between geographical distribution to genetic divergence as estimated by D2 statistics. The maximum inter cluster distance was observed between cluster IV and VII, while minimum was recorded between III and IV.
