Abstract: India’s chilli production, essential for both domestic and export markets, depends on genetic diversity. This study assessed the variability among 24 chilli genotypes. The analysis of variance revealed significant differences among all genotypes for various traits. Notably, parameters related to growth, yield and biochemical attributes displayed substantial Phenotypic Coefficient of Variation (PCV) and Genotypic Coefficient of Variation (GCV), indicating considerable genetic diversity. Interestingly, PCV slightly exceeded GCV, suggesting a relatively lower impact of the environment on these traits. Crucially, high values of both phenotypic and genetic coefficients of variation highlighted significant potential for improvement through selective breeding. Traits exhibited high heritability, coupled with high to moderate genetic gains, except for the number of pickings. This indicated the prominence of additive gene action, emphasizing the effectiveness of selection processes. In essence, the study shows substantial potential for enhancing chilli genotypes via selection, due to the notable genetic diversity in crucial traits.
