Abstract An investigation was carried out involving forty brinjal genotypes with an objective to evaluate the variability and divergence among the genotypes. The experiment was laid out in Randomized Complete Block Design and observations were recorded on 25 growth, yield and quality traits. Significant differences among the genotypes for all the characters were observed except total chlorophyll content. High PCV and GCV were observed for fruit volume, fruit weight, fruit length, number of fruits, leaf area index, fruit diameter, number of fruits per cluster and fruit yield per hectare. High heritability coupled with high genetic advance were observed for fruit volume, fruit weight, yield per plant, leaf area index and fruit borer incidence. Correlation studies indicated positive significant correlation of plant height, days to first flowering, and number of branches at 60 days after transplanting, number of flowers per cluster, fruit set, fruit yield per plant, number of clusters per plant, number of fruits per cluster, fruit length with yield per hectare. Path analysis results showed that number of clusters per plant exerted more positive direct effect on fruit yield. It also revealed that simultaneous improvement of single fruit weight, number of fruits per plant and fruit length may enhance the fruit yield. Genetic divergence studies using Mahalanobis D2 statistics grouped 40 genotypes in to fifteen clusters. Maximum genotypes were grouped in the dusters III with nine genotypes followed by cluster IV (7), cluster VII (2) and cluster XIV (1). Maximum contribution towards divergence was by fruit yield per hectare and fruit yield per plant. Based on performance of genotypes for fruit yield, the genotypes viz., Arka Shirish, R-2587 and L-3271 were found to be promising.
