Abstract:
A field experiment was conducted at Vegetable Research Station, SKLTSHU, Hyderabad, Telangana State, India during August, 2020 - January, 2021 to study the performance of red onion varieties under late kharif conditions in Southern Telangana. Experiment was conducted with five entries Bhima Super, Bhima Shakti, Bhima Red, DOGR-1669 and DOGR-1657. The experiment was laid out in Randomized Block Design replicated four times. All the five varieties were round in shape, predominant bulb colour of DOGR-1657 and Bhima Shakti was red, DOGR-1669, Bhima Super and Bhima Red were light red. Among the five entries tested, DOGR-1669 recorded the maximum mean bulb weight (90.85 g) which was significantly superior over other entries but was at par with Bhima Super (88.45 g). DOGR-1669 recorded the highest total yield (45.43 t ha^-1) and marketable yield (43.82 t ha^-1) compared to other entries followed by Bhima Super and Bhima Shakti. Highest TSS (10.20 ⁰Brix) was observed in the variety DOGR-1669 followed by DOGR-1657. Bolter bulbs were not noticed in DOGR-1669 and Bhima Super and rotten bulbs were not noticed in DOGR-1669 and DOGR-1657. Maximum bolter bulbs were noticed in DOGR-1657, maximum rotten bulbs were noticed in Bhima Super. Least incidence of thrips was noticed in Bhima Shakti followed by DOGR-1669 and least incidence of purple blotch in DOGR-1657 followed by DOGR-1669. Maximum thrips incidence and maximum purple blotch was observed in Bhima Super followed by Bhima Red.
