Eggplant or brinjal [Solanum melongena L.] is the most popular and widely cultivated vegetable crop in the central, Southern and Southeast Asia and in some African countries. In the present investigation 55 genotypes were collected and evaluated at the Research Farm of Department of Biotechnology and Crop Improvement during Khari season of 2015 to assess genetic variability, heritability, genetic advance and genetic diversity. Estimates of phenotypic coefficients of variability (PCV) and genotypic coefficients of variability (GCV) ranged for average fruit weight (18.00- 176.70) followed by plant spread (51.70-87.60) respectively. PCV were slightly higher than the corresponding GCV and the difference was very low for majority of the characters, suggesting that prevalence of more of genetic effects than environment in their expression. Heritability in broad sense (h2), genetic advance (GA) and genetic advance as percentage of mean (GAM) ranged between 19-79-100%, 0.55-70.63, 23.17- 104.14 % respectively. High GCV, PCV, heritability coupled with high genetic advance indicating more of genetic inheritance and selection is effective. The genotypes CBB-23 (cluster XIV), A2 (cluster XIII), CBB-2 (cluster XII), CBB-50, CBB-49, A11, CBB-43, CBB-52 and CBB-64 (cluster XI) showed high genetic diversity giving room to improvement through hybridization between these genotypes. Therefore, direct selection helps in selecting good genotypes with high growth, yield and quality for brinjal hybrids.
