New elite sugarcane clone Yunzhe 92-19

New elite sugarcane clone Yunzhe 92 19, which is early maturing, high sucrose and yield is introduced in this paper. The clone has the ability of good germination rates, medium tiller, strong seedling, early jointing and good vigour. The stem is thick, high and erect. Millable stems are more than 75000 per ha. The yield is between 85-100 t·hm-2, increasing yield 15%-20% than check variety (Guitang11). Sucrose is more than 14% in November, the average (November-March ) sucrose is more than 15%, increasing 0.5%-0.8% than check. The sucrose contents per ha reach 13-16 t, 20% higher than that of check. Yunzhe 92 19 has abilities of good ratooning, resistance to smut, mosaic and drought. It is suitable to be planted in paddy field or upland with irrigation. 
