The study on “Genetic variability and character association analysis in white onion (Allium cepa L.) genotypes” was conducted during rabi 2024-25 at IGKV, Raipur using 14 genotypes in RBD with three replications. Significant variability was observed for yield and its components. WTA-24-14 (365.04 q/ha) was the highest yielder, followed by WTA-24-04 and WTA-24-07. High GCV, PCV, heritability and genetic advance were recorded for % A grade bulbs, number of bulbs per plot, average bulb weight and total yield. Total yield showed strong positive correlations with number of bulbs per plot, bulb weight, marketable yield and vegetative growth characters. Path analysis revealed that number of bulbs per plot, average bulb weight, neck length, marketable yield and bulb diameter exerted direct positive effects on yield, suggesting these traits as key selection criteria for genetic improvement.
