Abstract: Qiantang 8 was selected by Guizhou Institute of Subtropics Crops in 2007, and the hybrid combination is Neijiang 00/118(♀) and Guitang 94/119(♂). This new sugarcane varieties with high yield, high sucrose and resistance was selected successfully by sugarcane cross breeding program. It is characterized with late maturity and middle size, seedling emergence rate 38.6%, tillering rate 54.0%, plant height 299.1 cm, stem diameter 3.05 cm, active stems per hectare 77 262, sucrose content 13.7%, yield 148 327.5 kg/hm², the sucrose content was 0.2% higher than that of the control variety(ROC22), and yield of Qiantang 8 was increased by 34.4% compared with control variety(ROC22). The variety has wide adaptability, strong resistance to inversion, good roots, high yield and stable yield. In 2016, it was approved by Guizhou Provincial Committee of Crop Variey Examiration and Approval, named Qiantang 8.
