摘要 黔糖8号是贵州省亚热带作物研究所2007年以内江00/118×桂糖94/119为杂交组合,按甘蔗杂交育种程序,选育成功的高产高糖耐逆甘蔗新品种。该品种属晚熟、中大茎种,出苗率38.6%,分蘖率54.0%,株高299.1 cm,茎径3.05 cm,每公顷有效茎77262条,蔗糖含量13.7%,单产148327.5 kg/hm^2,蔗糖含量比对照ROC22(13.5%)高0.2个百分点,单产增加34.4%,且适应性广,耐逆性强,宿根性好,丰产稳产。2016年通过贵州省农作物品种审定委员会审定,命名为黔糖8号。 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 77262,sucrose content 13.7%,yield 148327.5 kg/hm^2,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.
