摘　　要：采用灰色关联度分析方法,选用8个主要性状,对2007—2009年参加广西区域试验的10个甘蔗引进新品种进行综合评价。结果表明,C1-2003关联度最接近参考品种,台98/0432、粤糖96/86次之,分别排在第1～3位,综合性状表现优良,可考虑进一步繁殖、示范和推广;福农15号关联度排在第4位,产量一般,但蔗糖分含量较高,在育种上可作为早熟、高糖杂交亲本加以利用;其余品种综合性状表现一般,有待进一步试验观察。The ten new sugarcane varieties,which were used in Guangxi sugarcane regional test from 2007 to 2009,were evaluated by grey relation degree（GRD） analysis.The results showed that the GRD of C1-2003 was closest to the reference variety,and Tai 98/0432,Yuetang 98/86 ranked 2 and 3,respectively.The above varieties with excellent characters had good prospect to be widely used on propagation,demonstration and extension in the further.Ranked at the fourth of GRD,Funong15 can be used as a hybrid parent for breeding due to its high sucrose content.Other varieties had not good performance on GRD analysis.
