Genetic Variability Studies in Chilli (Capsicum annuum L.) Genotypes under the Mid Hill region of Himachal Pradesh, India

Abstract

A field experiment was carried out at the Vegetable farm of Dr Y S Parmar University of Horticulture and Forestry, Nauni to evaluate variability parameters of fifteen yield and yield contributing characters in twenty-five chilli genotypes during the Kharif season 2020-21. The analysis of variance revealed significant differences among all the genotypes studied. High phenotypic coefficient of variation (PCV) and genotypic coefficient of variation (GCV) were observed for nine characters except for days to 50% flowering, fruit length and fruit diameter, plant height, days to maturity (mature green) and days to maturity (red ripe stage). High estimates of PCV and GCV coupled with high heritability and genetic gain were recorded for nine traits indicating the existence of additive gene action and these traits can be improved through selection.
