Brinjal (Solanum melongena L.) is an important solanaceous vegetable crop cultivated throughout the world. Thirty eight genotypes were evaluated in RBD with 3 replications in GBPUA&T, Pantnagar for the analysis of genetic divergence. The present study evaluated genetic diversity of accessions through genetic components analyses, and genetic divergence by multivariate and principal component analysis (PCA). Thirty eight genotypes were meaningfully grouped into seven clusters. Cluster III was the largest having fourteen genotypes followed by cluster I, cluster II, cluster IV, cluster V, cluster VI and cluster VII had minimum genotypes. There is no direct relationship between geographical distribution and genetic distance. Among the seven clusters, cluster III showed maximum intra-cluster distance followed by cluster II. Based on inter-cluster distances, the maximum divergence was observed between cluster IV and cluster VII indicating that the genotypes in these clusters could be utilized as parents in hybridization programme to develop high heterotic hybrids and to identify transgressive segregant in F2 generation. Among the studied characters number fruit per plants showed maximum contribution towards the diversity. On the basis of principal component analysis and average values, genotypes ‘Pusa Kaushal’, ‘PB-70’ and ‘Niranjan’ possessed optimum combinations of all variables and could be utilized as donor parents in breeding of eggplant.
