Abstract: A study was conducted using 13 collections and 30 F1 hybrids of brinjal. The analysis of variance revealed highly significant differences among genotypes. Wide range of variability was observed for most of the traits under study. Mean value for days to first fruit picking was 62.01 with a range of 50.70-70.39. Range for number of fruits plant-1 was 10.47 to 27.62 with a mean value of 15.06, for fruit weight and fruit yield ha-1 mean values were 119.95g and 568.38 qha-1while range for these was 82.55-149.90g and 305.25-969.4 qha-1 respectively. Phenotypic variances were slightly higher than corresponding genotypic variances for all the traits studied. Broad sense heritability was high for all the characters studied. Genetic advance as percentage of mean was medium to high for all the parameters studied. High heritability along with high genetic advance as percent of mean were observed for days to first flowering, plant height, plant spread, fruit diameter, no of fruits plant-1, fruit yield, fruit dry matter, Vitamin C and total phenols indicating predominance of additive gene effects and reliability of such traits for effective selection procedure.
