高糖、高产甘蔗新品种重要性状分析及模糊综合评判

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

对12个参试品种蔗茎产量、蔗糖分、含糖量等进行分析比较,并对其进行模糊综合评判。结果表明,新台糖21、新台糖22、桂糖94-119、桂糖93-102四个品种的综合表现优于新台糖16,这些品种产蔗量、含糖量优于对照,综合农艺性状较好,其中桂糖93-102蔗糖分优于新台糖16,桂糖94-119蔗糖分与新台糖16相近;新台糖20、巴西45、粤糖93-159、新台糖23、台优1、桂糖94-116、台优2七个品种的综合表现不如新台糖16,其中巴西45虽然产量较高,但11月蔗糖分、平均蔗糖分均低于新台糖16,其它几个品种突出的缺点是蔗茎产量偏低。

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.
