Assessment of Genetic Variability in Chilli (Capsicum annuum L.) Genotypes for Growth and Yield Traits

Abstract

Genetic variability, heritability, and genetic advance as a percent of mean were evaluated for 17 characters in chillithrough field assessment. The study encompassed all observed traits and analysis of variance revealed significant variability among genotypes for each character. Notably, Number of fruits per plant, Average fresh fruit weight (g), Green chilli yield per plant (g), Dry chilli yield per plant (g), Dry chilli yield per plot (kg), and Dry chilli yield per/ha (q) exhibited higher values for both Genotypic Coefficient of Variation (GCV) and Phenotypic Coefficient of Variation (PCV), indicating substantial genetic variability with minimal environmental influence.Plant height (cm), Average fresh fruit weight (g), Number of fruits per plant, Fruit diameter (mm), Number of seeds/fruit, Green chilli yield per plant (g), Dry chilli yield per plant (g), Dry chilli yield per plot (kg), and Dry chilli yield per/ha (q) demonstrated high heritability and genetic advance as a percent of mean. This suggests the prevalence of additive gene action in the inheritance of these yield attributes. Consequently, simple selection is anticipated to be effective for enhancing these traits.
