Abstract: An experiment was conducted at College of Horticulture, Kolar District during Rabi season of 2016-17. In this study a total of 28 genotypes were collected from different parts of India and evaluated using randomized complete block design with two replications. The growth and yield parameters viz., plant height(cm), leaf length(cm), number of leaves per plant, leaf width(cm), yield per plot (kg/plot), yield per hectare (t/ha), average bulb weight(g), ten bulb weight(g), polar and equatorial diameter(cm) were recorded during an experiment. The data indicated that out of 28 genotypes evaluated, Arka Swadistawas recorded maximum plant height (74.6cm) and leaf length (66.83cm). With respect to leaf width, ON-15-42 was indicated maximum leaf width of 2.25cm. However with respect to number of leaves, GJWO-3 was registered maximum leaves (11.20). Whereas, ON-14-09 and GJWO-3 were performed better and produced maximum bulb yield of 13.25 and 11.82kg/per plot. The minimum bulb yield was recorded in the genotype BSS-255 (6.29 kg/plot). The yield per hectare was revealed highest in the genotypes ON-14-09(44.12t/ha) and GJWO- 3 (39.37 t/ha). Out of 28 genotypes, ON-14-09 and GJWO-3 were noticed maximum average bulb weight of 113.40 and 105.55g, respectively. The ten bulb weight was recorded highest in the genotypes ON-14-09 (968.75g) and GJWO-3 (902.45g). The polar diameter was indicated highest in the genotypes Bhima Safeda (6.91cm) and Pusa White Round(6.61cm). An equatorial diameter was recorded highest in the genotype ON-14-09 (7.36cm). Therefore from the study, it was concluded that the genotypes GJWO-3 and ON-14-09 were found better with respect to bulb yield production in Rabi season.
