桂糖33号(原编号桂糖02-770)是广西甘蔗研究所从桂糖69-156×新台糖22号杂交组合后代中选育的最新甘蔗优良品种。该品种表现为中熟、高糖、丰产、易剥叶等优良特性。2008—2009年广西区试结果显示,平均蔗茎产量114.83 t/hm2,分别比对照种CK1(ROC22)和CK2(ROC16)增产13.01%和22.90%,平均含糖量为15.81t/hm2,分别比CK1与CK2增产9.64%和17.02%。其中,新植蔗产蔗量为118.92 t/hm2,分别比CK1和CK2增产16.47%和26.19%;平均含糖量为16.42 t/hm2,分别比CK1与CK2增产14.58%和21.63%。该品种适应性广,蔗茎粗大且生长均匀,增产幅度大。该品种于2011年5月通过广西农作物品种审定委员会审定正式命名为桂糖33号。
Gui Sugar 33 (original code Gui Sugar 02-770) is the latest sugarcane variety of Guangxi Sugarcane Research Institute selected from the offspring of the crosses of Guitang 69-156 × Xintai 22. The varieties showed moderate, high sugar, high yield, easy to peel leaves and other fine features. The result of Guangxi regional trial from 2008 to 2009 showed that the average cane yield was 114.83 t / hm2, which increased 13.01% and 22.90% respectively than CK1 (ROC22) and CK2 (ROC16), with the average sugar content of 15.81 t / hm2 Than the CK1 and CK2 yield 9.64% and 17.02%. Among them, the sugarcane yield of new sugarcane was 118.92 t / hm2, which increased 16.47% and 26.19% respectively than CK1 and CK2; the average sugar content was 16.42 t / hm2, which increased 14.58% and 21.63% respectively than CK1 and CK2. Wide adaptability of the varieties, cane stems and uniform growth, increase yield. The variety in May 2011 through the Guangxi Crop Variety Approval Committee officially named Gui sugar No. 33.
