Abstract
A promising midlate maturing sugarcane variety viz., Doiyang (Co Bln 02173) was developed at the Sugarcane Research Station, Buralikson from the general collection of Co 88039GC through clonal selection. The variety was tested in the state varietal trials, AICRP trials and onfarm trials in the different agroclimatic zones of Assam. Under normal spring planting Doiyang showed an average cane yield of 75.27 t/ha and sugar yield of 11.27 t/ha with an improvement of 25%for cane yield and 8% CCS yield over the best standard CoSe 92423 in the plant crop. The ratooning ability was 24% and 32% better for cane yield and sugar yield respectively than the check. The variety was moderately resistant to red rot and borers (early shoot, top and plassy borer). The performance of the variety under autumn planting was excellent with an average cane yield of 102.8 t/ha and 85.3 t/ha under plant and ratoon crop conditions respectively and hence was recommended for autumn planting in the North Eastern India and was released by the Assam State Seed Sub Committee.
