Genetic Variability, Heritability and genetic advance for quality traits in carrot (Daucus carota L.)

Genetic improvement of any crop depends upon the presence of genetic variability. The exploration of genetic variability in the available germplasm is a prerequisite in a breeding programme for effective selection of superior genotype. The partitioning of total variability into heritable and non-heritable components by using suitable design will enable the breeder to know whether the superiority of selection is inherited by the progenies. So, there is an urgent need of information on the nature and magnitude of variation available in the material and part played by environment in expression of different characters. So, it is desirable to conduct variability studies such as genotypic and phenotypic coefficient of variation (GCV & PCV), heritability and genetic advance in thirty eight diverse genotypes of carrot.
