Abstract:
A white onion variety “Gujarat Junagadh White Onion-3” (GJWO-3) developed by Vegetable Research Station, Junagadh Agricultural University, Junagadh, which was evaluated under state trials during 2005-06 to 2014-15 at various locations along with check varieties; PWF-131, GWO-1 and GAWO-2. On the basis of mean bulb yield data, GJWO-3 recorded the highest bulb yield of 398.03 q/ha as compared to check varieties; PWF-131 (329.54 q/ha), GWO-1 (357.75 q/ha) and GAWO-2 (369.26 q/ha), which was 20.8, 11.3 and 7.8 percent higher, respectively. The bulbs of this variety are medium in size, flat globe in shape and white in color. Regarding quality parameters, this variety contains higher TSS (13.15%), total carbohydrates (7.97%), total protein (1.19%), ascorbic acid (3.19 mg/g), total phenol (18.23 mg/100 g), pyruvic acid (11.35) and total soluble sugar (1.04%) as compared to check varieties. This variety also recorded less jointed bulb percentage (1.70%) as compared to check varieties. It has good tolerance against purple blotch disease (13.88%) as compared to check varieties; PWF-131 (23.52%), GWO-1 (21.59%) and GAWO-2 (16.05%). Thrips population was also less (6.08/leaf) in GJWO-3 variety as compared to check varieties; PWF-131(9.43/leaf), GWO-1 (8.23/leaf) and GAWO-2 (7.40/leaf).
