Sixty brinjal germplasm lines were evaluated for fourteen quantitative characters. High PCV and GCV values were seen forplant height, plant spread, number of branches per plant, number of fruits per cluster, average fruit diameter, average fruitweight, shoot and fruit borer incidence on shoot and fruit and fruit yield per plant indicating high variability in thegermplasm. In general, values of PCV were higher than the values of GCV indicating influence of environment butdifferences between PCV and GCV values were minimum, indicating that the traits under study were less influenced byenvironment and these characters could be improved by following phenotypic selection. . Genetic advance as per cent ofmean were high (>20.0) for plant height (25.00), plant spread (115.07), average fruit weight (25.23) and shoot and fruitborer incidence on shoot (21.53).High heritability accompanied with high genetic advance was noticed for plant height,plant spread, average fruit weight and shoot and fruit borer incidence on shoot indicating that simple selection may beeffective to fix and improve such traits.
