Abstract:

The present investigation was carried out to study the vvariability and heritability component estimates for different characters of carrot. The experimental material comprised of 96 genotypes of carrot and laid out in an augmented block design comprising of 3 checks (Ghataprabha Local, Vigro Kuruda and Pusa Vrishti) with 6 blocks to screen the genotypes comprising of European and Asiatic types with diverse colors at University of horticultural Sciences, Bagalkot during 2016-2017. Observations were recorded on 18 quantitative traits including root and plant morphological traits. Analysis of variance revealed highly significant differences among the genotypes for all the characters. Phenotypic coefficient of variation (PCV) was higher than the genotypic coefficient of variation (GCV) which indicates the role of environmental factors on the expression of various traits studied in the present investigation. Yield parameters like root weight, vegetative weight, harvest index possessed higher values of GCV, heritability and genetic gain. These are the most important traits for applying selection in carrot for crop improvement.
