Abstract
In two distinct environments (E1 and E2), the current experiment was set up using a randomized block design with the goal of determining the extent of genetic diversity, heritability, and genetic advancement among 15 yield-related variables in brinjal. The analysis of variance results revealed that there were significant genetic variances across brinjal genotypes, indicating a significant degree of variability and boosting the opportunity for selection to improve the essential traits. There was a noticeable variance in mean values between the genotypes for several traits, from modest to wide. For most of the features under investigation, with the exception of days to 50% flowering, moderate to high genotypic coefficient of variation, moderate to high heritability, and genetic advancement as a percentage of mean were reported.
