摘要
采用灰色关联分析方法综合评价第8轮国家区域试验的10个甘蔗新品种(系)。结果表明,加权关联度值大于新台糖22(CK1)的包括云蔗05-51、柳城03-1137、福农39和云蔗06-407共4个品种,亦是参试品种中含糖量优于或最接近CK1的品种;除了福农36含糖量约低于新台糖16(CK2)外其余新品种(系)含糖量均大于CK2;赣南02-70、云蔗05-51、柳城03-1137、福农39、赣南02-70和福农02-5707等6个品种的加权关联度值均大于新台糖16(CK2),亦是参试品种中蔗糖分优于或最接近CK2(高糖CK)的品种;其中赣南02-70是参试品种中蔗糖分表现最佳的品种,可用作高糖亲本。该评价结果与参试品种的田间综合表现相吻合。建议云蔗05-51、柳城03-1137、云蔗06-407、福农39等4个品种(系)可以在云南瑞丽及其气候相似蔗区推广应用。
10 new sugarcane varieties （ lines ） in the 82 national test in Ruili, Yunnan were comprehensively evaluated by the method of grey correlation analysis. The weighted correlation values of YLmzhe 05-51, Liucbeng 03-1137, Funong 39 and Yunzhe 06-407 were higher than that of Xintaitang 22 （ CK1 ）, and their sugar contents were higher than or near that in CK1. The weighted correlation values of Gannan 02-70, Yunzhe 05-51, Liucheng 03-1137, Funong 39 and Furlong 02-5707 were higher than that of Xintaitang 16 （ CK2 ）, and their sugar contents were higher than or near that in CK2. Among tested varieties Gannan 02-70 could be used as high sugar parent because of its highest sugar content. The results of evaluation were the same as the comprehensive per- formance of tested varieties in the field. It is proposed that Yunzhe 05-51, Liucheng 03-1137, Yunzhe 06-407 and Furlong 39 can be grown and popularized in the climate as Ruili of Yunnan.
