Genetic Variability in Summer Brinjal (Solanum melongena L.)

Abstract

Twenty two brinjal (Solanum melongena L.) genotypes were collected and grown in summer season and variability estimates were studied for twenty two different quality, yield, its attributing traits. High genotypic and phenotypic coefficient of variation was obtained for characters like length of style, fruit girth, average fruit weight, number of fruits per plant, yield per plant, total yield per hectare, total sugar, reducing sugar, titrable acidity, ascorbic acid, total antioxidant capacity, total phenolic content and polyphenol oxidase. Heritability and genetic gain as percent of mean was observed to be high for characters such as plant height, number of primary branches, length of style, fruit length, fruit girth, average fruit weight, number of fruit per plant, yield per plant, total yield per hectare, TSS, total sugar, reducing sugar, titrable acidity, ascorbic acid, total antioxidant capacity, total phenolic content and polyphenol oxidase. High heritability coupled with high predicted genetic gain suggests for selection based on these traits for enhancement of yield and quality.
