Abstract: The present investigation “Assessment of genetic variability in brinjal (Solanum melongena L.)” was carried out during kharif season of 2017-2018 at the farm of AKS University, Satna (M.P.). The experimental material for the present investigation was comprised of 19 genotypes of brinjal. These genotypes were sown in Randomized Complete Block Design with three replications, to observed morphological characters and to estimate the genetic variability. Observations were recorded on the basis of five random competitive plants selected from each genotype separately for morphological characters. The mean performance of the genotypes revealed a wide range of variability for all the traits. The variation was highest for number of leaves plant^-1 (118.13 to 245.53), followed by fresh fruit weight (63.94 to 170.39), plant height at final harvest (61.90 to 124.17), fruit yield hectare^-1 (47.26 to 78.97), days to first fruit set (41.80 to 54.93) and days to 50 per cent flowering (31.33 to 42.00). The PCV was higher than the GCV for all the characters. High genotypic coefficient of variation and phenotypic coefficient of variation was noted for fresh fruits weight (31.66, 31.96) followed by number of fruit plant^-1 (27.50, 28.14), fruit length (27.02, 27.50) and number of leaves plant^-1 (23.63, 24.76). The high values of GCV suggested greater genotypic variability among the genotypes and responsiveness of the attributes for making further improvement by selection. High heritability coupled with high genetic advance for traits like fresh fruit weight (98.12, 64.61) followed by number of fruits plant^-1 (95.52, 55.35), fruit length (96.52, 54.67) and number of leaves plant^-1 (91.07, 46.46). Suggested that the preponderance of additive genes. It also indicated higher response for selection of high yielding genotypes as these characters are governed by additive gene actions.
