基　　金：糖料蔗突破性新品种选育及关键技术研究与应用示范项目(2022AA01025);糖料蔗产业科技先锋队项目(桂农科盟202303-9);国家现代农业产业技术体系广西甘蔗创新团队项目(nycytxgxcxtd-2021-03)。

摘　　要：【目的】探讨广西新育成及引进的甘蔗优良品系在柳州试点的表现,为新品种的选育、登记和推广提供重要依据。【方法】2019—2021年,在柳州市农业科学研究中心甘蔗试验基地开展以“新台糖22号”(CK1)、“柳城05-136”(CK2)和8个甘蔗新品种1年新植2年宿根的广西区域试验,探讨各品种间的农艺性状、产量、糖分、含糖量、纤维分、病虫害表现。【结果】“桂糖11-2011”表现发株率高,抗病性较好,平均蔗茎产量为82.02 t/hm^(2),分别比CK1、CK2高4.09个百分点、0.29个百分点,平均产糖量为12.66 t/hm^(2),分别比CK1、CK2高11.35个百分点、3.01个百分点,该品种平均蔗糖分为15.47%,为早熟高产高糖品种,是本轮区试中综合性状表现较好的品种。【结论】“桂糖11-2011”可进一步在柳州蔗区进行试验示范及推广。【Objective】The purpose of this study was to discuss the performance of the newly bred and introduced sugarcane varieties in Liuzhou pilot,as well as to provide an important basis for the breeding,registration and promotion of new varieties.【Methods】From 2019 to 2021,the Guangxi regional trials of“Xintaitang No.22”(control 1),“Liucheng No.05-136”(control 2)and eight new sugarcane varieties with one-year new planting and two-year ratooning were carried out in the sugarcane test base of Liuzhou Agricultural Science Research Center.The agronomic traits,yield,sugar,sugar cuntent,fibre content,diseases and insect pests of each variety were discussed.【Results】The results showed that“Guitang No.11-2011”had high plant occurrence rate and good disease resistance.The average cane yield was 82.02 t/hm^(2),which were 4.09 and 0.29 percentage points higher than those of control 1 and control 2,respectively.The sugar yield was 12.66 t/hm^(2),which were 11.35 and 3.01 percentage points higher than those of control 1 and control 2,respectively.The average sucrose content of“Guitang No.11-2011”was 15.47%,which was the variety with advantages of early maturity,high-yield and high-sugar.“Guitang No.11-2011”was a variety with better comprehensive traits in this round of regional trials.【Conclusion】“Guitang No.11-2011”could be further demonstrated and promoted in Liuzhou sugarcane production area.
