| 摘 要： | 本文应用灰色关联分析法,对重庆引进的七个龙眼新品种进行了综合评估,明确了优良品种。作者认为,和等权关联度排序相比较,加权关联度排序的评估结果更能反映品种产量、品质、生长情况的实际表现;构造“参考品种”和赋予不同性状以不同的权重是灰色关联分析的关键环节。

| Abstract: | By using mathematical method of relational grade analysis of the grey system theory,seven new longan varieties introduced were multifactorialy evaluated.The best varieties were defined.Compared with equal relational grade analysis,the weighted grade analysis was more reliable in assessing actual expression of yield quality growth and other characteristics of longan variety.Forming the reference variety and giving different traits with different measures were key steps of the relational grade analysis. |
