Abstract

A wide range of variability was recorded for different characters studied in carrot. The highest root weight (81 g) and yield (216.63 q/ha) was recorded in Badau Local Rampal. Maximum root length (17.67 cm) was recorded in Doctor Deshi Red. The PCV and GCV varied from 3.71 to 20.88 and 2.46 to 15.75% respectively. The highest heritability (83.0%) was recorded for character TSS and lowest heritability (26.20%) was recorded for character root length. The strong positive correlation was found in root to shoot ratio, root weight and yield. Root weight showed maximum direct effect on yield.
