Abstract

The purpose of this study was to determine the nature, extent and magnitude of genetic variability, as well as estimate of the coefficient of variability, heritability and genetic advance as a percentage of the mean. During the rabi, 2020-21, twenty-three diverse genotypes of carrot were laid out in RCBD design at the Experimental Farm of the Department of Vegetable Science, College of Horticulture and Forestry, Neri, Hamirpur, Himachal Pradesh. Observations were recorded on sixteen economic traits. For all traits, significant differences were found among all genotypes. PCV was greater than the corresponding GCV for all the traits, indicating that the environment has a significant impact on character expression. GCV, heritability and genetic advance as per cent of mean were high for root: shoot ratio, plant height at harvest, carotene content and total yield per plot, indicating that selection for these traits would be beneficial in improving carrot yield.
