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).
