Assessment of genetic variability and path analysis in carrot (Daucus carota L.) genotypes

Naresh Kumar, Amrita Nigam and Akshay Kumar Pathak

Studied of genetic variability and its component traits and path analysis were carried out among fifteen genotypes of carrot (Daucus carota L). Highly significant differences between genotypes were observed for all the characters. A moderate to wide range of mean value for different characters were observed among the genotypes. Moderate to high genotypic co-efficient of variation, phenotypic co-efficient of variation with moderate to high heritability, direct and indirect effect of genotypic and phenotypic path analysis on yield qt / ha. and genetic advance as percentage of mean was investigate for majority of the characters. High genotypic co-efficient of variation, phenotypic co-efficient of variation, heritability, genetic advance as percent of mean, genetic gain and path analysis were observed for flesh thickness (cm), net root weight / five plant (kg), yield (qt. / ha.), inner core diameter (cm), vitamin A (I U), β carotene content (mg / 100 g fresh weight), root girth (cm) and root length (cm). The present study revealed that, presence of substantial amount of variability in the genotypes and the important yield components are flesh thickness (cm), net root weight / five plant (kg), yield (qt / ha), vitamin A (IU), β carotene content (mg / 100 g fresh weight), root girth (cm) and root length (cm). It was concluded that selection based on flesh thickness (cm), root length (cm), root girth (cm), net root weight / five plants (kg), β carotene content (mg / 100 g fresh weight), vitamin A (I U) and yield (qt. / ha.) may improve yield.
