Abstract
The present investigation entitled “Morphological Characterization and Disease Reaction Studies in Bell Pepper” was carried out at the Experimental Farm of Department of Vegetable Science, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during Kharif, 2022. Thirty-four advanced breeding lines/ genotypes of bell pepper along with two standard check varieties (California Wonder and Solan Bharpur) were evaluated for morphological characters based on DUS along with analysis of various horticultural traits and disease reaction to Phytophthora leaf blight and fruit rot. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications and the genotypes were morphologically classified based on forty-two DUS traits. Analysis of variance for horticultural traits revealed significant differences among all the genotypes for most of the characters under study. Genotypes UHF-CAP-108, UHF-CAP-119, IIHR-131, UHF-CAP-106 and UHF-CAP-113 were found to be significantly superior than the better check variety i.e., Solan Bharpur for fruit yield per plant with desirable medium sized, dark green, glossy and 3-4 lobed fruits. Hence, these genotypes should be tested in multi-locational and multi-year trials so that the most superior and stable genotype(s) can be recommended for commercial cultivation. Among various parameters of variability, fruit yield per plant, number of fruits per plant and fruit weight had high values of coefficients of variation as well as high heritability coupled with high genetic gain indicaThe present investigation entitled “Morphological Characterization and Disease Reaction Studies in Bell Pepper” was carried out at the Experimental Farm of Department of Vegetable Science, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during Kharif, 2022.

Hence, these genotypes should be tested in multi-locational and multi-year trials so that the most superior and stable genotype(s) can be recommended for commercial cultivation. Among various parameters of variability, fruit yield per plant, number of fruits per plant and fruit weight had high values of coefficients of variation as well as high heritability coupled with high genetic gain indicating the prevalence of additive gene action. Correlation coefficient depicted that number of fruits per plant, fruit weight, number of lobes per fruit, internodal length, pericarp thickness, plant height, plant spread, leaf area, leaf length and leaf width were significantly and positively correlated with fruit yield per plant. Thus, selection of genotypes on the basis of these traits would be effective in improving fruit yield per plant. The maximum positive direct effect on fruit yield per plant was contributed by number of fruits per plant followed by fruit weight, leaf area, plant height, pericarp thickness and thousand seed weight. Thus, improvement in these characters will lead to higher fruit yield per plant in bell pepper. Genetic divergence studies revealed that hybridization between genotypes of cluster IV and VI will be more rewarding for getting superior hybrids. In case of disease reaction studies, no genotype was found to be resistant to Phytophthora leaf blight and fruit rot but moderate susceptibility was found in genotypes UHF-CAP-104, UHF-CAP-107, UHF-CAP-111, UHF-CAP-116, UHF-CAP-119, UHF-CAP-127, IIHR-131 and check variety Solan BharpurThe present investigation entitled “Morphological Characterization and Disease Reaction Studies in Bell Pepper” was carried out at the Experimental Farm of Department of Vegetable Science, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during Kharif, 2022.
