Abstract: Mutation breeding plays a major role to create genetic variation in crop plants. Mutation in chrysanthemum species has a significant impact on the plant morphology, growth and floral characteristics. In this study genetic variability, heritability and genetic advance was studied for twelve yield character and its components during 2022-23 and 2023-24 and pooled mean of both the environment were calculated. Analysis of variance showed significant among all the genotypes for all the yield and its components, suggesting presence of significance amount of variance. Days to flower bud appearance (40.84; 40.92) had highest GCV and PCV value followed followed by Duration of flowering (38.47; 38.54). The lowest value was observed for diameter of flower per plant (13.68; 16.16). Characters showed high value of GCV and PCV were primary branches per plant, secondary branches per plant, suckers per plant, days to flower bud appearance, days to 50 % flowering, stalk length, numbers of flowers per plant, weight of flowers per plant, duration of flowering and yield of flower per plant this indicates that considering this trait for direct selection will result in genetic improvement and high heritability along with high genetic advance can be used efficient selection for further breeding programme.
