Assessment of genetic variability, heritability and genetic advance of Chrysanthemum

Abstract

An experiment was conducted to study genetic variability, heritability and genetic advance among twenty varieties of chrysanthemum (Chrysanthemum morifolium Ramat.) at the College Farm, College of Horticulture, Department of Floriculture and Landscape Architecture, SDAU, Jagudan during 2020-21. A wide variation in performance of the varieties were recorded for various growth, flowering, yield and quality parameters and results shows that magnitude of the phenotypic coefficient of variation (PCV) was higher than genetic coefficient of variance (GCV). High GCV and PCV was recorded for fresh weight of flower followed by number of leaves per plant, number of flowers per plant, number of primary branches, shelf life, yield of flowers per plant and yield of flowers per plot. High heritability along with high genetic advance as per cent of mean was observed for number of leaves per plant, days to full bloom, number of flowers per plant, yield of flowers per plant and yield of flowers per ha. Further, these characters could be exploited for improvement through breeding programme.
