摘要
基于灰色关联度分析法,选取16个品种性状,对引种自浙江金华30个春鹃品种进行综合评价。结果表明各春鹃品种灰色关联度在0.90以上的有5个,依次是‘红阳’、‘丹顶’、‘大吉祥’、‘春潮’和‘常春3号’。而灰色关联度在0.78以下,多个指标排名靠后的品种为‘白香玉’、‘粉霞’和‘雪晴’。从研究结果来看,评价结果与各品种的田间表现基本吻合,表明利用灰色关联度分析法来评价筛选春鹃品种切实可行。该方法可为春鹃品种在园林应用和春鹃育种材料的选择等提供参考。
Based on the grey-relational grade method,16 characters were selected to make a comprehensive evaluation of 30 Rhododendron simsii varieties introduced from Jinhua,Zhejiang Province. The results showed that there were 5Rhododendron simsii varieties with a grey-relational degree of more than 0.90,followed by ‘Hongyang’,‘Dajixiang’,‘Chunchao’,‘Danding’ and ‘Changchun No. 3’. The varieties with the grey-relational degree below 0.78 were ‘Bai Xiangyu’,‘Fenxia’ and‘Xueqing’,which showed many low indicators. In the view of the results,the evaluation results are basically consistent with the field performance of each variety,indicating that it is feasible to evaluate and select Rhododendron simsii varieties by grey-relational grade method. This method can provide references for the Rhododendron simsii varieties in garden application and the selection of parental backbone materials in Rhododendron simsii breeding.
