Online published on 20 May, 2023. Abstract The present investigation was carried out with 10 genotypes for genetic variability, which revealed that the environmental influence was very low on the expression of these characters as it was evident by the narrow gap between genotypic and phenotypic coefficients of variation. Genotypic and phenotypic coefficients of variation were moderate to high for all the characters studied except for height of the plant, leaf length, duration of crop, and bulb diameter. Moderate to high heritability was observed for all characters and high genetic advance as per cent mean was recorded for number of bulbs, fresh bulb weight, dry bulb weight, yield per plot and yield per hectare, indicating that simple selection would be sufficient for these traits to bring genetic improvement.
