Fifty genotypes of chrysanthemum were evaluated in randomized complete block design during the year 2022 (Kharif) to determine genetic variability, heritability and genetic advance for different quantitative and qualitative traits, based on which selection may be made. It was conducted at research block of the Department of Floriculture and Landscape Architecture, College of Horticulture, UHS campus, Bengaluru. To determine genetic variability, heritability and genetic advance for different quantitative and qualitative traits, based on which selection may be made. Analysis of variance showed significant differences among genotypes for all the characters studied. Results revealed that magnitude of the Phenotypic Coefficient of Variation (PCV) was higher than Genotypic Coefficient of Variation (GCV) for all the traits viz., number of primary branches, number of secondary branches, duration of flowering, number of flowers per plant, weight of hundred flowers, yield per plant, flower diameter, total number of ray florets per flower head, petiole length, shelf life and disc diameter indicating genotype and environment interaction. Highest heritability coupled with genetic advance as percent mean was found for all the traits. The characters that endowed with high heritability with values high genetic advance as percent mean may be used as selection criteria in genetic improvement of yield.
