| 摘 要： | 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。 |

| Abstract: | A new sugarcane variety of Guitang 33(Guitang02-770) was bred from the hybrid offspring in cross combination by Guitang69-156×ROC22.The variety was characterized by mid maturation,high sugar,high yield,easy to peel leaves,wide adaptability and uniform thick cane.The results from regional sugarcane varieties trial in Guangxi from 2008 to 2009 predicated that:the average cane stalk yield was 114.83 t/ha,higher than CK1(ROC22) with 13.01% and CK2(ROC16) with 22.90% respectively.The average sugar yield was 15.81 t/ha,higher than CK1 with 9.64% and CK2 with 17.02% respectively.The plant cane stalk yield was 118.92 t/ha,higher than 16.47% of CK1 and 26.19% of CK2 respectively,the average sugar yield was 16.42 t/ha,higher than CK1 with 14.58% and CK2 with 21.63%,respectively.The variety named Guitang 33 was registered by Guangxi Crop Variety Approval Committee on May 2011. |
