Abstract:
A field experiment was conducted at Vegetable Research Station, SKLTSHU, Hyderabad, Telangana, India during kharif season (July-December, 2020) to study the performance of red onion varieties under short day conditions in Southern Telangana Zone. Experiment was conducted with five varieties Bhima Dark Red, Bhima Super, Bhima Red, DOGR-1625 and DOGR-1626. The varieties were replicated four times laid in Randomized Block Design. The predominant bulb colour of Bhima Red and DOGR-1626 was light red, Bhima Dark Red, Bhima Super and DOGR-1625 was Red. The bulb shape of Bhima Red was round and the rest were oval. The uniformity of bulb size was high in Bhima Dark Red, Bhima Super and DOGR-1625 and average in case of Bhima Red and DOGR-1626. Among the five entries tested, Bhima Dark Red recorded significantly superior mean bulb weight (71.35 g), total yield (35.64 t ha^-1) and marketable yield (34.38 t ha^-1) over other varieties but was at par with DOGR-1625 and DOGR-1626. The Highest TSS of 13.30⁰Brix was observed in the variety DOGR-1625. Least percent of double bulbs were noticed in Bhima Dark Red. Least percent of bolter bulbs was noticed in DOGR-1626 (0.82%) followed by Bhima Dark Red (0.96%) and least percent of rotten bulbs was noticed in Bhima Dark Red (6.01%) followed by DOGR-1625 (9.68). Least incidence of thrips (1.75) and purple blotch (19.35%) was noticed in Bhima Dark Red.
