Abstract: Ten genotypes were evaluated as a part of the experiment indicated significant differences among genotypes for all traits. Pooled mean performances showed that Agrifound Dark Red had highest plant height (51.42 cm), average bulb weight (75.06 g), total bulb yield (306.42 q ha-1) and marketable bulb yield (295.09 q ha-1). High GCV was recorded for Plant height, number of leaves, polar diameter, equatorial diameter, neck thickness, average marketable bulb weight, marketable yield, days to maturity, total soluble solids, pyruvic acid and phenol content in bulbs. High heritability was observed for most of the characters. Total bulb yield was positively and significantly correlated with plant height (0.802), number of leaves (0.630), polar diameter (0.572), equatorial diameter (0.919) and average bulb weight (0.974). Superior genotypes like Agrifound Dark Red (313.49 q ha-1 and 299.35 q ha-1) and Gota (287.43 q ha-1 and 275.93 q ha-1) exhibited high total yield in both the locations Kalyani and Bankura of West Bengal, India.
