Abstract: In order to determine the magnitude of variability, 11 genotypes of chilli were evaluated at AICRP on Vegetable crops, Bhubaneswar centre. Through analysis of variance, a high significant difference was found for almost all characters indicating a greater opportunity of exploit variability. Genotypic and phenotypic variances were highest for fruit yield /plant followed by fruit weight and no. of fruits/plant. Phenotypic co- efficient of variation (PCV) and Genotypic co-efficient of variation (GCV) were maximum in case of no. of plants affected by leaf curl/plot followed by fruit weight and no. of wilted plants/plot. Heritability (bs) was highest for fruit weight followed by no. of fruits/plant and no. of borer affected fruits /plant. The maximum genetic advance (% of mean) was observed in case of no. of plants affected by leaf curl/plot followed by fruit weight and fruit borer/plant. Genotypic coefficient of variation, heritability and predicted genetic gain were high for the characters fruit weight, leaf curl incidence, fruit borer incidence and no. of fruits/plant suggesting that additive gene action is responsible for expression of these characters.
