Abstract: Twenty five brinjal (Solanum melongena L.) genotypes were evaluated under the Gangetic plains of West Bengal to determine genetic divergence with the help of multivariate analysis. The genotypes were logically grouped into six clusters on the basis of divergence analysis. The grouping pattern of genotypes indicated no direct relationship between geographical distribution and genetic distance. Inter-mating between the genotypes included in Clusters IV and VI or Cluster III and VI having high divergence will be expected to give heterotic response in F1 generation. Among the characters, fruit weight contributed the maximum divergence towards total genetic divergence followed by plant height, days to 50% flowering and fruit yield per plant. Four out of 9 characters had eigenvalue more than 1 and together accounted for 100% of total variation. Based on D2 statistics, principal component analysis and average values, five genotypes namely, BCB-40, KS-224, White Jhuri Begun, 10/BRBW/ RES-3 and 16/BRL var-8 possessed distinct differences of their genotypic characters and optimum combinations of all variables which could be used as parents in hybridization programme for the development of high yielding brinjal variety.
