It matures in 115-120 days and is adapted specifically to Rabi season. The culture recorded an average seed yield of 3245 kg/ha, with a mean grain yield advantage of 26 % over the popular check M 35-1and 12.3 % over the local check SVT 68 in the trials conducted during 2016-2022. The culture is moderately resistant to charcoal rot, recorded on par pest reaction score with respect to resistant checks for the insect pests of shoot fly, stem borer, aphids and fall army worm. It has high crude protein content (10.96 %) and good roti quality.
