Abstract: Genetic variability, heritability and genetic advance for different quality characters, i.e. total soluble solids (TSS), dry matter, carotene, juice yield and total sugars, were studied in 28 carrot genotypes grown during 2002/03 and 2003/04 in Ludhiana, Punjab, India. Analysis revealed the existence of considerable amount of genetic variability for all characters studied. Carotene content exhibited the highest value of genotypic and phenotypic coefficient of variation, heritability (broad sense) and genetic advance as percentage of mean, indicating that this character can be effectively improved through selection.
