Studies of genetic variability and relationship among the 40 genotypes of European carrot (Daucus carota L.var sativa) for important horticultural traits revealed wide range of variability for the traits.Little or no differences between genotypic coefficient Outdoor Sofa/Chairs/Table Set (Set of 4) of variation (GCV) and phenotypic coefficient of variation (PCV) for all traits confirmed low environmental influence.

High PCV for root diameter, root weight, root yield and flesh thickness indicated additive gene action.High heritability with high to moderate genetic advance for flesh thickness, root length, root diameter suggested additive gene action and scope for improvement through selection.Higher genotypic correlation revealed inherent association among the traits.

Strong character association of root weight, root length, and crown diameter with root yield suggested as selection criteria for higher yield.Adequate genetic variability within the germplasm indicated enormous scope for genetic improvement of yield and quality traits.Root weight had maximum direct effect on Leather Baseball Keychain Gift Box root yield (q/ha).

It was concluded that selection based on root weight, root length, root diameter and crown diameter may improve yield.
