摘要
1 999- 2 0 0 2年 ,在广西甘蔗研究所试验农场进行 1 5个优良品系和 2个对照品种的 2年新植和 1年宿根的区域试验。福农 91 - 471 0、闽糖 86 - 2 1 2 1、粤糖 92 - 1 2 6和云蔗 92 - 1 9在试验中表现较突出。福农 91 - 471 0产蔗量和含糖量最高 ,分别达 99.4 0和 1 4 .0 3t· hm-2 ;闽糖 86 - 2 1 2 1和粤糖 92 -1 2 6产蔗量和含糖量分别为 95 .5 1、1 3.5 4t·hm-2 和 90 .2 3、1 3.71 t· hm-2 ;而主对照新台糖 1 0号(CK1 )和副对照桂糖 1 1号 (CK2 )的产蔗量和含糖量分别为 78.82、1 1 .87t· hm-2 和 88.5 3、1 2 .4 9t· hm-2 。云蔗 92 - 1 9在参试材料中蔗糖分最高 ,达 1 5 .4 8% ,而新台糖 1 0号和桂糖 1 1号糖分仅分别为 1 4 .97%和 1 4 .1 5 %。
From 1999 to 2002, a regional test including 15 promissing sugarcane lines and 2 control varieties was conducted in Guangxi Sugrcane Research Institute, which lasted for 2 plant crops and 1 ratoon crop. It was showed that Funong 91 4710, Mintang 86 2121, Yuetang 92 126 and Yunzhe 92 19 were significantly superior to the 2 controls in general performance. Funong 91 4710 produced the hightest cane and sugar yield ( 99.40 t·hm -2 and 14.03 t·hm -2 ), and a reasonable sugar content (13.91%). Those of Mintang 86 2121 and Yuetang 92 126 were 99.51 t·hm -2, 13.54 t·hm -2 , 14.12% and 90.23 t·hm -2 , 13.71 t·hm -2 , 15.24% respectively, compared with 78.82 t·hm -2 , 11.87 t·hm -2 and 14.87% for Xintaitang 10 (CK 1) and 88.53 t·hm -2 , 12.49 t·hm -2 , 14.15% for Guitang 11 (CK 2). The sugar content of Yunzhe 92 19 was the highest of the tested lines, which was 15.48% from November to February. While that of Xintaitang 10 and Guitang 11 were 14.97% and 14.15% respectively.
