The present investigation was carried out during kharif 2016-17 at Horticultural Research Station, Lam, and Guntur with 44 genotypes of paprika (Capsicum annuum
L.) in a randomized block design with two replications to estimate the genetic variability, heritability and genetic advance for thirteen quantitative traits. Analysis of variance revealed significant differences among the genotypes for all the traits studied indicating the presence of sufficient variability in the studied material. The PCV was higher than GCV and the difference between PCV and GCV was narrow for most of the characters revealing little influence of the environment in the expression of these traits. High magnitude of PCV and GCV were observed for number of fruits per plant, fruit diameter, number of seeds per fruit, weight of seeds per fruit, 1000 seed weight and dry fruit yield per plant suggesting the existence of wide range of genetic variability in the germplasm for these traits and thus the scope for improvement of these characters through simple selection would be better. High heritability coupled with high genetic advance as per cent of mean was observed for all the characters except plant height, plant spread, number of primary branches per plant and days to 50% flowering indicating the predominance of additive gene action making the simple selection more effective.
