Abstract:

Ten genotypes of chrysanthemum were evaluated under naturally-ventilated polyhouse in Completely Randomized Block Design during the year 2017-18 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, indicating genotype and environment interaction. High (>20%) PCV and GCV was observed for number of secondary branches, number of leaves, leaf area, stem girth, days to flower bud initiation and days to first flowering. Heritability estimates ranged from a moderate 55.10% (number of secondary branches/plant) to high as 99.74% (Days to flower bud initiation). High heritability (>60%) was observed for all traits except number of secondary branches/plant. Estimates of high heritability coupled with high genetic advance as per cent of mean (GAM) were observed for all the growth, flowering, yield and quality parameters studied indicating the possible role of additive gene action.
