2013—2014年广西甘蔗新品种区域试验在河池点的表现

Performance of New Sugarcane Varieties in Hechi in 2013-2014 of Guangxi Regional Trial

为筛选适合河池蔗区种植的甘蔗新品种．2013--2014年在河池农业科学研究所以ROC22为对照开展11个甘蔗新品种2年新植1年宿根的区域试验，分析各参试品种的农艺性状指标、蔗茎产量、蔗糖分及含糖量等。试验结果表明：柳城05／136、桂糖07／994、桂糖07／1721、桂糖06／244、桂糖06／3283和桂糖03／3005的综合表现较好，其余参试品种表现一般。柳城05／136、桂糖07／994、桂糖06／3283、桂糖03／3005蔗糖分较ROC22的高0．23-0．82个百分点，桂糖07／1721、桂糖06／244与ROC22相当：柳城05／136、桂糖07／994、桂糖07／1721、桂糖06／244、桂糖06／3283、桂糖03／3005的蔗茎产量、公顷含糖量均较ROC22的高．增幅分别为5．11％-37．52％、6．74％～37．83％。

The objective of this study was to test adaptability, yield performance and sugar content of new sugarcane varieties in order to select appropriate ones for planting in Hechi sugarcane regions. Two planting cane and one-year-old ratoon were conducted using 11 new sugarcane varieties and 1 control variety （ROC22） during 2013-2014 in Hechi Research Institute of Agricultural Sciences. The results showed that sugarcane varieties LC5-136, GT 07-994, GT 07-1721, GT 06-244, GT 06-3283 and GT 03-3005 had the better performance and the rest varieties had general performance. Compared to ROC22, the sucrose content of LC 05-136, GT 07-994, GT 06-3283, GT 03-3005 was increased by 0.23 ~ 0.82 percent point, the sucrose content of GT 07-1721, GT 06-244 was similar. Compared to ROC22, the cane yield and sugar yield of LC05-136, GT 07-994, GT 07- 1721, GT 06-244, Guitang06-3283 and GT 03-3005 was increased by 5.11% - 37.52% and 6.72% - 37.85% respectively.
