Genetic variability, heritability and genetic advances in brinjal (Solanum melongena L.)

Two experiments were carried out consecutively during 2019 and 2020 to assess the variability among the 112 genotypes of brinjal at Venanallur located in Ariyalur district (TN). These genotypes were evaluated for ten growth and nine yield attributing parameters. Analysis of variance revealed highly significant differences for all the traits. Higher values for PCV and GCV were observed for pseudo and true short styled flowers, fruit set, fruit yield per plant, seeds per fruit, medium styled flowers, and fruit girth. High heritability percentage was observed for fruit girth, seeds per fruit, fruit length, leaf area index, fruits per plant, fruit set, average fruit weight and pseudo and true short styled flowers. High genetic advance along with high heritability percentage was observed for pseudo and true short styled flowers, fruit set percentage, and fruit yield per plant indicating the predominant of additive gene action suggesting a better scope for selection of superior parents for further breeding programme.
