Abstract
The sorghum K13 is a high yielding dual purpose Sorghum variety suitable for rainfed vertisol tracts of Southern distracts of Tamil Nadu. TKSV 1036 is a hybrid derivative of the cross ICSB 518 x SPV 1489 and evolved with an objective of development of dual purpose Sorghum variety suited for both grain and fodder purpose, it recorded an average grain yield of 2575 kg/ha over 118 locations which is 10.7 per cent and 3.5 per cent increase over K12 and CO 30 respectively. TKSV 1036 is a dual purpose sorghum variety which gave an average dry fodder yield of 11.4 tonnes/ha, which is 26.6 % increase over check variety K12. It mature in 95-100 days. The crop is of tan plant type, tolerant to drought and non-lodging. Grains are highly acceptable, creamy white colour, born on medium cylindrical semi compact earheads. The sorghum culture TKSV 1036 is resistant to shoot fly and stem borer and moderately resistant to midge. It is highly resistant to ergot, resistant to downy mildew, grain mould rest and showed moderate resistance to leaf blight and anthracnose. Hence, the sorghum culture TKSV 1036 has been proposed for new release during 2023 and released as sorghum K13 for general cultivation in Southern district or Tamil Nadu.
