Abstract: The investigations were carried out in Department of Vegetable crops, Bidhan Chandra Krishi Viswavidyalaya, West Bengal to examine the magnitude of genetic divergence among 70 entries of brinjal. The lot of 70 entries (10 elite varieties, 16 stable breeding lines and 44 indigenous cultivars of India and Bangladesh) based on multivariate analysis using Mahalanobis’ D2-statistic employing 18 growth, yield components, fruit yield and fruit quality could be grouped into 6 clusters. Relatively lesser number of clusters, moderate and consistent intra-cluster divergence and low contribution of all the characters towards divergence indicated that either common character constellation was manifested simultaneously in the genotypes or mutual balancing in character expression was operative the genotypes of brinjal.
