【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。更多还原

【Abstract】 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.更多还原
