Sachin Utagi, Anjanappa M., Muthal, K.M. and Mahesh Badiger

Abstract

Twenty cultivars of onion were evaluated in Central Dry Zone of Karnataka during late kharif season. Among those cultivars Bhima Super recorded highest plant height (59.11 cm), maximum number of leaves (9.87), maximum neck thickness (1.34 cm), highest polar diameter of bulb (5.50 cm), highest equatorial diameter of bulb (5.73 cm), maximum average bulb weight (82.42 g), maximum estimated total bulb yield (40.33 t/ha) and maximum marketable bulb yield (40.19 t/ha), where as Bhima Kiran and Bhima Raj recorded zero bolting per cent and Agri Found Dark Red and Arka Bindu were recorded minimum number of days to harvest (102 days each). Bhima Raj recorded the highest bulb shape index (1.12) and Bhima Shubra recorded the minimum percentage of double bulbs (0.83%). Arka Bindu recorded the maximum firmness of the bulb (9.87 kg/sq. cm), TSS (17.23%) and per cent dry matter content of bulbs (26.47%) and Super Flare recorded the minimum pyruvic acid (4.00 μmol. g-1 FW). The cultivars Bhima Super, Bhima Red and Bhima Shakti which gave higher bulb yield, marketable bulb yield, bulb weight, polar diameter of bulb and equatorial diameter of bulb can be taken up for raising profitable crop of onion in Central Dry Zone of Karnataka.
