Variability studies for 18 quantitative characters revealed that the phenotypic coefficient of variation (PCV) was comparatively greater than the corresponding genotypic coefficient of variation (GCV) for all the characters studied. Maximum PCV (59.49%) and GCV (59.48%) were registered for fruit weight. High estimates of heritability accompanied with high genetic advance as per cent of mean were  recorded for most of the traits viz., fruit length, diameter, pedicel length, pedicel thickness, relative fruit calyx length, fruit weight, fruits per plant, the number of marketable fruits, marketable fruit yield and fruit yield per plant indicating the prominence of additive gene action, thus pointing towards the effectiveness of simple selection depending on the phenotypic expression of genotypes would be rewarding for genetic improvement of these characters. Significant positive correlation of fruit yield per plant at both genotypic and phenotypic levels with plant height, percentage of medium and long styled flowers, fruit setting percentage, fruit length, fruit diameter, fruit pedicel length, fruit pedicel thickness, fruit weight, marketable fruit yield and significant negative correlation with the number of primary branches, days to 50% flowering, days to first harvest, relative fruit calyx length, fruits per plant, total marketable fruits. Therefore, considering these characters would be beneficial in the selection for fruit yield per plant.Keywords: Brinjal, Genetic variability, Correlation analysis ER -
