Genetic Variability, Hybrids, Heritability, Genetic AdvanceAbstract
Investigations were made on yield and quality in six hybrids of carrot spanning two seasons under Nilgiri hill conditions during the year 2012-2013. The hybrids were evaluated for per se performance, genotypic coefficient of variance, heritability and genetic advance. A high estimate for genotypic coefficient of variation was observed in root-splitting percentage, total chlorophyll, root carotenoids, leaf carotenoids and root-forking percentage in the hybrids, indicating a potential for improvement of these traits by simple selection, in kharif and summer. Leaf and root carotenoid content, total chlorophyll, number of leaves and root weight exhibited higher values for heritability, coupled with a high genetic advance, revealing these traits to be under the control of gene action. Simple selection can, therefore, effect improvement in these characters.Downloads
