The aim of the present experiment was to investigate the phenotypic and genotypic variance among different varieties of brinjal (Solanum melongena L.), as well as three check varieties, using a randomized complete block design with two replications. The focus of the study was on yield-related traits, including fruit length, girth, and weight. The results showed that the phenotypic coefficient of variation (PCV) and genotypic coefficient of variation (GCV) was high for these traits, with values above 20%, indicating the presence of high variability within the population. This suggests that there is significant potential for improvement through selection. Additionally, positive skewness and high values of kurtosis were observed for several traits, including several clusters per plant, days to first picking, fruit weight, fruit length, fruit girth, yield per plant, and plant height. This suggests that these traits usually are generally distributed within the population and are likely influenced by complementary gene action. Overall, this study’s results suggest considerable potential for improving yield in brinjal through selective breeding efforts.
• The information found from the analysis of skewness and kurtosis can be used to form a breeding program.
• Effectively identifying the dominant gene action.
