22个糖料甘蔗品种(系)在广西的种性表现与初步评价

Character performance and preliminary evaluation of 22 sugarcane varieties( lines) in Guangxi

用21个糖料甘蔗新品种进行新植和宿根品比试验,以新台糖22号为对照(CK),调查其主要农艺性状、经济性状和抗逆性,并对蔗茎产量和含糖量进行分析。结果表明,桂糖07-108、桂糖42号、桂糖49号、桂柳05-136、福农41号等5个品种(系)蔗糖分高,蔗茎产量和含糖量均显著高于CK,综合性状最好;桂糖31号、桂糖32号、桂糖29号、桂糖36号、桂糖40号和粤糖60号等6个品种(系)的蔗糖分、蔗茎产量和含糖量与CK相当;粤糖28号、桂糖30号、桂糖37号、桂糖41号、桂糖43号、福农38号、福农39号、云蔗04-241和云蔗05-53等9个品种(系)比CK减产减糖;云蔗04-241、云蔗05-53和云蔗06-407表现晚熟,含糖量比CK减产达极显著水平。

21 new sugarcane varieties were treated in plant and ratoon test for comparison,taking Xintaitang No. 22 as the control,and their main agronomic traits,economic characters,stress resistance characters,cane yield and sugar yield were investigated and analyzed. The results showed that 5 varieties（ lines） such as GT 07-108,GT 42,GT 49,Liucheng 05-136 and Funong 41 had significantly higher cane yield and sucrose content than the control,with the best comprehensive characters. Cane yield and sucrose content of 6 varieties（ lines） such as GT 31,GT 32,GT 29,GT 36,GT 40 and Yuetang 60 were the same as those of the control.Other 9 varieties（ lines） such as Yuetang 28,GT 30,GT 37,GT 41,GT 43,Funong 38,Funong 39,Yunzhe 04-241 and Yunzhe05-53 had lower cane yield and sucrose content than the control. Yunzhe 04-241,Yunzhe 05-53 and Yunzhe 06-407 performed late mature and their sucrose content was extremely significantly lower than that of the control.
