摘要: 针对牡丹切花生产的专用目标,基于灰色关联度分析法,选取14个性状构建“标准品种”,对51个紫斑牡丹(Paeonia rockii)品种进行评价并筛选出适宜切花的品种,为牡丹切花生产提供重要的种质资源。结果表明:参试品种分为4类:第Ⅰ类4个品种,关联度为0.7841 ~ 0.8203,为适宜切花的品种,分别是‘京玉红’、‘粉面桃腮’、‘京粉岚’及‘京冠辉红’;第Ⅱ类14个品种,关联度为0.7082 ~ 0.7561,具备良好的切花生产潜力,为较适宜切花的品种;第 Ⅲ 类19个品种,关联度为0.6361 ~ 0.6950,切花生产潜力一般,可作为后备切花品种资源;第 Ⅳ 类14个品种,关联度为0.5771 ~ 0.6291,不适宜作切花。

Abstract: In order to screen out the cultivars suitable for cut-flower production,we investigated 14 traits in 51 cultivars of flare tree peony(Paeonia rockii)and built an“Ideal Cultivar”to comprehensively evaluate them by using grey relational grade analysis method. Through systematic cluster analysis of weighted relational grade,the 51 cultivars were divided into four groups. The first group included 4 cultivars,‘Jingyuhong’,‘Fenmian Taosai’,‘Jingfenlan’and‘Jingguan Huihong’,with weighted relational grade of 0.7841–0.8203,which were the most suitable to be used for cut-flower and popularized preferentially. The second group included 14 cultivars with weighted relational grade of 0.7082–0.7561 which were greatly potential for cut-flower production,and they were recommended to be more suitable for cut-flower application. The third group including 19 cultivars with weighted relational grade of 0.6361–0.6950 had general potential for cut-flower and could be recommended as reserve resources for cut-flower. The fourth group included 14 cultivars with weighted relational grade of 0.5771–0.6291 and they were not suitable to be used for cut-flower production.
