Sixty three genotypes of brinjal were studied to estimate mean performance, variability, heritability, genetic advance and trait relationship. High genotypic and phenotypic coefficients of variation were obtained for petiole length, leaf breadth, fruit length, fruit diameter, individual fruit weight and fruit yield per plant. Heritability and genetic advance were also high for these traits indicating the possibility of selection to improve these characters. Among the genotypes, VRSM-26 produced the highest fruit yield (2879.66 g/plant) followed by VRSM-21 (2341.33 g/plant). Average fruit weight ranged from 3.67 g (VRSM-17) to 95.67 g (VRSM-23). Genetic variability studies showed high PCV and GCV values for fruit yield and average fruit weight. High heritability coupled with high genetic advance as percent mean was observed for all the characters studied except plant height. Fruit yield per plant showed positive and significant correlation with petiole length, leaf length, fruit length, fruit diameter and single fruit weight at both phenotypic and genotypic levels.
