以17个日本杜鹃品种为材料,选取其生长性、观赏性、抗逆性3个方面11个性状为评价因子,运用层次分析法(AHP)和灰色关联度法相结合的方法开展日本杜鹃品种综合评价.结果表明:应用层次分析法得到影响日本杜鹃品种的各个评价因子权重排序,其中花量、越冬度夏、花型、花色等指标权重值较高.基于灰色关联法和聚类分析法,将供试品种分成4个等级,包括Ⅰ级'若枫'('Wakakaede')1种,Ⅱ级'鹃之舞'('Kinu-no-Mai')等4种,Ⅲ级'华宝'('Kaho')等8种,Ⅳ级'红石南'('Beni-shakunan')等4种.评价结果和各品种的实际观察结果一致,表明此方法切实可行,可为筛选出有较高观赏性又便于育种推广的花卉植物提供参考.
The Comprehensive Evaluation and Screening of Japanese Rhodoendron Cultivars by Analytic Hierarchy Process-Grey Relation Analysis
Takeing 17 Japanese Rhodoendron cultivars as materials,as the evaluation factor,3 aspects and 11 characters of the growth character,ornamental character,stress resistance were selected.Japanese Rhodoendron cultivars were comprehensively evaluated by analytic hierarchy process(AHP)and grey relation analysis method.The results showed that the weight sort of evaluation factor of Japanese Rhodoendron cultivars were obtained by using AHP method,in which the index weight value of amount of flower,through summer and winter,flower pattern,flower color are higher.Test varieties were divided into 4 grades based on grey relation analysis and clustering analysis,includeing 1 species of'Wakakaede'in Grade Ⅰ,4 species of'Kinu-no-Mai'in Grade Ⅱ,8 species of'Kaho'in Grade Ⅲ,4 species of'Beni-shakunan'in Grade N.The evaluation results of the study were consistent with the actual observation results of each cultivars,indicating that the method is feasible and can provide a reference for selecting flowers and plants with high ornamental value and easy breeding and popularization.
