Genotypic Variation for Quantitative and Qualititative Traits in Asiatic Carrot (Daucus carota L. var. sativa)

Abstract

Thirty two diverse genotypes of Asiatic carrot were evaluatc::d at the Research Farm, Indian Institute of Vegetable
Research, Varanasi during winter 2001 and 2002 for estimating the variability for eleven quantitative and qualititative
traits of horticultural importance. The analysis of variance was highly significant for all the traits indicating the
presence of wide variability in the genotypes. High heritability estimates were recorded for carotene content, average
fresh root weight with leaves, plant height, TSS and leave length. High estimates of genetic advance were recorded
for root weight with leaves and average fresh root weight. The high heritability was associated with high genetic
advance as per cent of mean for average fresh root weight, root weight with leaves, carotene content and TSS,
and found to be the most reliable selection parameters. HCP-191, Barwal-2, HC-155, HCP-183, HC-4-2, VN-11550K
and HC-2-A were recorded to be superior genotypes for yield and its components, which can be used in further
breeding programme.
