ABSTRACT
The investigation was conducted at Department of Horticulture, College of Agriculture, Vijayapur during, late kharif season of 2018. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Character association and path analysis in seventeen genotypes of brinjal were studied for 15 important characters. The correlation studies revealed that total yield per plant had significantly and positive association with plant height (0.504), plant spread (0.506), and number of primary branches (0.742), stem girth (0.746) at 90 days after transplanting, fruit length (0.313), fruit diameter (0.324) and fruit weight (0.825). While negatively and significantly associated with days to first flowering (-0.429), days to 50 % flowering (-0.362), days to first fruit maturity (-0.344), fruit length diameter ratio (-0.282) and number of fruits per cluster (-0.563) at both genotypic and phenotypic level. Narrow differences between the genotypic and phenotypic correlation coefficients were observed for various traits in the present findings. This indicates the lesser influence of the environment in the expression of these traits and presence of strong inherent association among the traits. Path analysis studies revealed that significant positive association at genotypic level among the traits viz., plant height (0.338), number of primary branches (0.680) at 90 days after transplanting, days to first flowering (0.706), days to first fruit maturity (0.562), fruit diameter (0.429), average fruit weight (1.22), number of fruits per cluster (0.198), number of fruits per plant (0.453) and phenol content in fruits (0.072) had exhibited true association with direct effect on yield per plant. The direct selection for these traits would be rewarding for improvement in the total yield per plant.
