Main Characteristics Analysis and Fuzzy Comprehensive Evaluation of Rich Sucrose and Yield Sugarcane Varieties

A 2-year field trial involving 12 sugarcane varieties with both rich sucrose and high cane yield was conducted to analyze the main characteristics including cane yield,sucrose content and sucrose yield,and the fuzzy comprehensive evaluation in the Nanning,Guangxi.The results showed that:(1)ROC21,ROC22,GX94-129 and GX93-102 were superior to control variety ROC16 in the cane yield and sucrose content as well as agronomic characters,and the GX93-102 had higher sucrose content than ROC16 while GX94-119 showed similar sucrose content as ROC16;(2)ROC20,Brazil 45,GD93-159,ROC23,Tai-you 1,GX94-116 and Tai-you 2 were inferior to ROC16 in comprehensive characters.Among those varieties,although it has a higher cane yield,Brazil 45 was inferior to ROC16 in its sucrose content and average sucrose content in November,while the others showed much lower cane yield.
