An experiment was conducted to study genetic variability, heritability and genetic advance among nineteen genotypes of newly evolved genotypes of chrysanthemum (Dendranthema grandiflora Tzvelev) for cut flower production at the experimental farm of ICAR-IARI Regional Research Station, Katrain, Kullu (H.P) for two successive years during 2017-2018. A wide range of variation in performance of the genotypes were recorded for various parameters and results shows that magnitude of the phenotypic coefficient of variation (PCV) was higher than Genetic Coefficient of variance (GCV) exhibiting that genotype and environment interaction. High (> 98.09%) PCV and GCV was observed for plant height, plant spread, number of stems per plant, flower diameter, days taken to flowering, duration of flowering, stem length, weight of cut stem, number of flowers per stem. Heritability estimates range from moderate to high i.e. (46.02) days taken to bud formation to plant height (98.09). Estimates of high heritability along with high genetic advance as percent GAM recorded for all vegetative and flowering parameters exhibiting the additive gene effect which could be further used for crop breeding programme.
