Abstract: The comparative demonstration experiments using new sugarcane variety‘Guifu98- 296’and dominant sugarcane variety‘ROC22’or‘ROC16’were conducted in 7 different ecological areas of Guangxi.The results showed that the average yields of‘Guifu98-296’achieved 103.29 t/hm2, increased 21.02 t/hm2 comparing with CK (82.27 t/hm2), and this was 25.55% higher than that of CK. The average sucrose of ‘Guifu98- 296’was 15.22% , 1.09% (absolute value) higher than that of CK (14.13% ). Sugar yield per hm2 of ‘Guifu98- 296’was 15.71 t, increased 4.07 t comparing with CK (11.65 t), and the increased percentage reached 34.97%. Benefit analysis per hm2 results showed that, farmer income increased 9879.40 yuan/hm2, and the sugar enterprises got 16845.89 yuan. So the total value of industrial and agricultural economic benefits increased 26725.29 yuan.
