Abstract: An investigation was carried out during kharif 2017-18 at College of Horticulture, Venkataramannagudem with 53 genotypes of chilli (Capsicum annuum L.) in a randomized block design with three replications to estimate the genetic variability, heritability and genetic advance for quantitative traits and chilli leaf curl virus resistance. 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 plant height, number of fruits per plant, fruit length, fruit width, fruit weight, number of seeds per fruit, red ripe fruit yield per plant, dry fruit yield per plant, capsaicin content, oleoresin content, ascorbic acid content, colour value, ChLCV disease incidence and disease severity 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 more effective. High heritability coupled with high genetic advance as per cent mean indicates existence of additive gene action which was observed in plant height, plant spread, number of primary branches per plant, days to 50 per cent flowering, number of fruits per plant, fruit length, fruit width, fruit weight, number of seeds per fruit, seed weight, fresh to dry recovery, capsaicin content, oleoresin content, ascorbic acid content, colour value, ChLCV disease incidence and disease severity. Hence, direct selection could be effective for desired genetic improvement for these traits.
