Genetic divergence studies in brinjal under temperate conditions

A.K. Singh, Naseer Ahmed, Surya Narayan

Abstract

Genetic divergence was studied using 29 brinjal genotypes. From the D2 statistics and canonical analysis, the genotypes were grouped into six clusters irrespective of geographical diversity indicating no parallelism between geographic and genetic diversity. Cluster II topped in having maximum fourteen genotypes, while cluster V and VI were solitary clusters. The maximum inter-cluster distance was noticed between cluster I and VI. Among characters contribution study, number of fruits/plant, plant height, average fruit yield/plant, number of branches/plant contributed maximum divergence and have a major role in improvement of fruit yield in brinjal.
