Genetic variability, heritability and genetic advance in chrysanthemum (Dendranthema grandiflora) genotypes evaluated for loose flower production
Twenty-five genotypes of chrysanthemum were evaluated for loose flower yield under open field conditions in a Completely Randomized Block Design during the year 2023-24 to ascertain their genetic variability, heritability and genetic advance for various quantitative and qualitative qualities that ca...

| description | Twenty-five genotypes of chrysanthemum were evaluated for loose flower yield under open field conditions in a Completely Randomized Block Design during the year 2023-24 to ascertain their genetic variability, heritability and genetic advance for various quantitative and qualitative qualities that can be used to choose parents. Analysis of variance exhibited noteworthy variation in the genetic potential of the genotypes for every trait under study. The magnitude of phenotypic coefficient of variation (PCV) for each trait was discovered to be higher than the genotypic coefficient of variation (GCV), which demonstrated an interaction between the genotype and environment. High (>20%) PCV and GCV were noticed for all the traits evaluated in the present study. Heritability estimates ranged from a low 29.78% (stem diameter) to as high as 99.968% (flower diameter). High heritability (>60%) was noted for each of the characteristics except stem diameter. All of the growth, flowering and yield examined, estimates of high heritability combined with high genetic advance as a percentage of mean (GAM) was found, suggesting that potential significance of additive gene action among the genotypes.
