Abstract
The present investigation was carried out in thirty two genotypes of brinjal with a view to estimate the extent of variability, analysis of variance and genetic divergence. The experiment was conducted in Randomized Block Design with three replications at Department of Vegetable Science, Acharya Narendra Deva University of Agriculture and Technology Narendra Nagar, (Kumarganj), Ayodhya (U.P.), during Kharif, 2020-21. Each treatment consisted of twelve plant in two rows, having spacing of 60 cm x 50 cm with net plot size of 1.2 m x 3.00 m2. The magnitudes of genotypic correlation was higher than the phenotypic correlation coefficients for all the character combinations. The most important trait, total fruit yield per plant had exhibited highly significant and positive phenotypic correlation with average fruit weight (0.747), number of fruits per plant (0.672) and fruit circumference (0.468) at both phenotypic and genotypic levels. Positive direct effect on total fruit yield was exerted by total sugars (0.474), average fruit weight (0.396), fruit circumference (0.358), number of fruits per plant (0.254), plant height (0.242), fruit polar length (0.194) and day to 50 % flowering (0.168). The higher magnitude of positive direct effect on total fruit yield was exerted by total sugars (0.474), average fruit weight (0.396), fruit circumference (0.358), number of fruits per plant (0.254), plant height (0.242), fruit polar length (0.194), day to 50 % flowering (0.168).
