Abstract: The present investigation conducted at Main Experiment Station, Department of Vegetable Science, Narendra Deva University of Agriculture and Technology, Narendra Nagar (Kumarganj) Ayodhya, involving 40 diverse genotypes of brinjal (Solanum melongena L.) in Randomized Block Design replicated thrice during kharif-Rabi-2017 to estimate the genetic variability, heritability (bs) and genetic advance in present of mean for planning the leading strategy in the available germplasm of brinjal. The observations were recorded on twelve quantitative traits viz. days to 50% flowering, plant height (cm), primary branches per plant, days to first fruit harvest, crop duration, fruits per plant, fruit length (cm), fruit circumference (cm), average fruit weight (g), marketable fruit yield per plant (kg), unmarketable fruit yield per plant (kg) and total fruit yield per plant (kg) and qualitative traits viz. fruit colour, fruit shape and calyx colour. The analyses of variance revealed that mean sum of squares due to genotypes were highly significant for all the traits indicating ample variation among the genotypes. Whereas, the higher magnitude of coefficient of variation at phenotypic level observed for fruits per plant (53.98%) followed by average fruit weight (43.36%), fruit circumference (34.63%), unmarketable fruit yield per plant (30.73%), marketable fruit yield per plant (26.64%) and total fruit yield per plant (23.99%). However, low variability recorded in the case of crop duration (5.62%).High heritability (>75) coupled with high genetic advance (>30) was observed for most of the traits except days to 50 per cent flowering, plant height, days to first fruit harvest and crop duration which indicated opportunity for selection response in available germplasm of eggplant.
