The third regional sugarcane variety test in Nanning, Guangxi

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.
