The present investigation carried out during autumn winter season 2021-2022 at the MES, Department of Vegetable Science, ANDUA&T, Kumarganj, Ayodhya (U.P.) with the objectives to estimate the genetic variability, heritability in broad sense and genetic advance in percent of mean among the 32 genotypes of brinjal including two checks Pant Rituraj and Pant Samrat. The ANOVA revealed that mean sum of squares due to genotypes was highly significant for all the traits indicating ample variation among the genotypes. The estimates of the PCV were higher than the GCV for all the traits. The highest PCV and GCV were observed for non-reducing sugar followed by reducing sugar, total sugar, no of fruits per plant. High heritability was recorded for all the characters except days to first fruit harvest and TSS. Genetic advance in per cent of mean ranged from 6.6 % to 110.46 %. It was high (>20) in total fruit yield per plant (38.41) and polar diameter of fruit length (38.39). High heritability coupled with high genetic advance (Ga) were recorded for the traits which are average fruit weight total, number of fruits/plant, fruit yield per plant, average fruit weight, total sugar, reducing sugar and non-reducing sugar. Therefore, from the above obtained results it can be concluded that there is great chance of effective crop improvement for greater yield and yield attributing traits.

Brinjal, GCV, PCV, heritability and genetic advance

The results for ANOVA showed that the mean square due to genotype was highly significant for all the characters indicating significant genetic variation which enables us to utilize genotypes in various breeding as well as improvement programmes. The characters showing high heritability coupled with high genetic advance provide a broad way for the improvement in genotypes for specific characters. The information may further help the breeders in formulating appropriate strategy aimed at getting higher yields and character improvement in brinjal.
