Abstract:
Eleven diverse genotypes of brinjal along with twenty four F₁s developed in line x tester fashion were evaluated for genetic variability, correlation and path coefficient for yield, its contributing traits and resistance to bacterial wilt. Significant and higher heritability was observed for percent plant survival against bacterial wilt followed by fruit circumference. High estimates of genotypic coefficient of variation, heritability and genetic advance as percent of mean for fruit yield, fruit weight, fruit length, fruit circumference, number of fruits per plant and percent plant survival against bacterial wilt indicated presence of additive gene action and suitability of these characters for further improvement by selection. Days to 50 % flowering recorded preponderance of non-additive gene action. Fruit yield showed positive significant association with fruit circumference and negative association with days to 50% flowering. Percent plant survival showed significant association with number fruits per plant. Path analysis revealed that fruit circumference followed by fruit length had highest direct effect on fruit yield.
