Genetic variability for root traits in carrot (Daucuscarota L.) evaluated under tropical condition

A study was conducted to evaluate the diverse carrot genotypes under tropical conditions for their genetic variability parameters during summer season 2015 at Haveli farm of UHS Bagalkot which represents the tropical region of Karnataka. Analysis of variance revealed significant variation among the genotypes for most of the characters. The range of variation and the genetic variability components such as genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) high for all the traits studied indicating the existence of variation for all the characters studied. Higher heritability was recorded by shoulder length and shoulder width and all the other characters showed low to moderate heritability indicating the influence of environment on these traits. The present investigation provides useful information about the genetic variation available in carrot for the root traits, which helps to plan a suitable strategy for the crop improvement of carrot to tropical region.
