Abstract

During 2021–2022, the Kittur Rani Channamma College of Horticulture in Arabhavi conducted an evaluation of the genetic variability in the F3 population of the cross Miraj Local × AAC-1 in China aster. Across all traits, the phenotypic coefficient of variation was greater than the genotypic coefficient of variation. For each plant, the number of branches, leaf area, number of leaves, number of flowers, flower yield, and seed yield were found to have high (>20%) phenotypic coefficient of variation (PCV) and genotypic coefficient of variation (GCV). For plant height, number of flowers per plant, flower yield per plant, and seed yield per plant, high heritability (>60%) combined with high genetic advance as percent over mean (>20%) was noted. These findings suggest that additive gene effects are responsible for the high heritability, which can be used to further agricultural improvement programs.

Conclusion

In conclusion, present study revealed that there was a wide range of variability existed in cross Miraj Local × AAC-1 for different growth, flowering, quality and yield parameters. Plants which exhibited different characters with high heritability coupled with high genetic advance would be effective for selection and utilized for breeding of high yielding China aster cultivars.
