Gujarat Junagadh Red Onion-11 (GJRO-11) – a new high yielding red onion variety
Abstract
To boost-up onion production in the Gujarat state, a new high yielding Red Onion Variety “Gujarat Junagadh Red Onion-11” (GJRO-11) developed by Vegetable Research Station, Junagadh Agricultural University, Junagadh, which was evaluated under state and co-ordinated trials during 2007-08 to 2013-14 at various locations along with check varieties AGFL-Red, Pilli Patti and Talaja Red. On the basis of mean bulb yield data, GJRO-11 recorded the highest bulb yield of 323.55 q/ha as compared to check varieties AGFL-Red (266.15 q/ha), Pilli Patti (272.55 q/ha) and Talaja Red (280.34 q/ha), which was 21.57, 18.71 and 15.41 per cent higher, respectively. Mean bulb yield in the AICRP trials revealed that GJRO-11 recorded mean bulb yield of 275.65 q/ha as compared to checks; Line-355 (345.62 q/ha), Bhima Kiran (332.43 q/ha) and Bhima Shakti (344.11q/ha). This genotype was not overtaken any of these checks in AINRPOG trials. The bulb of this variety are medium in size, flat globe in shape and red in colour. Regarding quality parameters, this variety contains higher TSS (12.94%), total carbohydrates (9.3%), total protein (1.16%), ascorbic acid (3.89 mg/g), total phenol (13.66 mg/100 g), pyruvic acid (1.22) and total soluble sugar (1.22%) as compared to check varieties. This variety also recorded less jointed bulb percent (2.04%) as compared to check varieties. It has good tolerance against purple blotch disease (12.67%) as compared to check varieties AGFL-R (20.33%), Pilli Patti (23.56%) and Talaja Red (24.28%). Thrips population was also less (5.70/leaf) in GJRO-11 variety as compared to check varieties; AGFL-Red (8.3/leaf), Pilli Patti (8.9/leaf) and Talaja Red (9.4/leaf).
