Abstract

The present investigation was undertaken during 2012 – 2013 with an objective to study the variability, heritability, character association and path analysis in sixteen genotypes of carrot. High estimate of genotypic coefficient of variation was observed for root splitting percentage, total chlorophyll, root carotene, leaf carotene and root forking percentage. High heritability with high genetic advance as per cent of mean recorded for the characters viz., leaf carotene, root carotene, total chlorophyll and root weight. Character association studies revealed the strong positive association of root yield with root carotene, root length, root weight, root diameter, inner core diameter, root forking percentage, root splitting percentage and leaf carotene. Path analysis indicated high positive direct effect of plant height, root length, root weight, root forking percentage, root splitting percentage and total chlorophyll on root yield.
