Abstract: Thirty nine genotypes of carrot representing the collections from diverse geographic area of the world were studies for variability, heritability, correlations and path analysis. Significant differences were observed for all the 17 characters studies. The PVC and GCV values were larger for specific leaf area, specific leaf dry weight, fresh weight of leaves, dry weight of leaves, fresh weight of roots, carotene content, percent forked roots and undersized roots. However, these PVC and GCV values were lower for rest of the traits. High heritability values associated with high genetic advance was observed for carotene content, root yield, fresh leaf weight, dry leaf weight, fresh weight of roots and specific leaf area, which indicated that selection for these characters will be effective. Rest of the characters had moderate or low heritability. The genotypes IHR 3, IHR 75, IHR 128 and IHR 205 exhibited deep orange colour of roots and these had high carotene content. Root yield was positively correlated with root length, root diameter, top length, fresh weight of roots, number of leave, fresh weight of leaves, dry weight of leaves, specific leaf of area and carotene content. Path analysis studies revealed that among the components characters, diameter of root exerted maximum positive effect on root yield both directly and also indirectly through traits like top length, specific leaf area and number of leaves.
