 ABSTRACT

The experiment Evaluation of onion landraces (Allium cepa L.) of Karnataka for yield and quality parameters during Rabi season was carried out during Rabi seasons  2015-16 at College of Horticulture, Kolar, Karnataka. In present investigation twenty five landraces were collected from all over Karnataka and evaluated by following RCBD with two replications. The growth characters appeared significant differences among the landraces evaluated. The genotype Kotturu Local exhibited maximum plant height (64.89 cm) and leaf length (60.21 cm). The maximum leaf width was noticed in the genotype Bellary Red (12.80). Of different genotypes, no double bulbs were registered in case of Kumata Sweet Onion, Thumbaraguddi Local, Rampur Local and Arka Kalyan. While, Bengaluru Rose Onion registered lowest collar thickness of 1.11 cm followed by Kumata Sweet Onion (1.16 cm). However, the genotype maximum number of rings per bulb was recorded in cultivar Mogalahalli Local (10.00) and Arka Kalyan (1.10) registered minimum number of centres. The quality parameters like TSS (16.80  ͦbrix) and pungency (6.50 µmol./g FW ) was recorded maximum  in genotype Kumata Sweet Onion. While, dry mater content was observed maximum in GBD-Bindu (21.75 %).  No bolting per cent was recorded in Belagavi White Onion and Thumbaraguddi Local. With respect to yield parameters, The maximum average ten bulb weight was recorded in Kadarakoppa Local (1230.00 g). However, the maxmum bulb yield per hectare was obtained in genotype Kottur Local  (35.34 t/ha). Considering the performance of different landraces with respect to growth, yield and quality traits Kotturu Local, Bellary Red and Kadarakoppa Local were performed best for Rabi season cultivation.
