Abstract

Genetic divergence among 14 eggplant genotypes was estimated using Mahalanobis’s D2 statistic. Altogether six clusters were formed. The maximum number of genotypes (5) was found in cluster III with intra cluster distance of 2 597.79. The maximum inter cluster distance was observed between cluster â…¡ and cluster â…¤. Hence, genotypes belonging to these clusters may be utilized for involving in hybridization programme for crop improvement. The characters of yield per plant, fruit circumference, little leaf incidence and total phenols content contributed more for genetic divergence.
