摘　　要：[目的]本文旨在建立多花型园林小菊品种的评价体系,开展品种观赏品质、生长特性和适应性的观测与综合评价,为品种筛选和新品种引进提供可靠的依据。[方法]连续2年通过田间观察统计,对69个多花型园林小菊品种主要品质性状数据进行分析,应用专家咨询法、层次分析法和K-Means聚类法建立评价体系。[结果]对69个多花型园林小菊品种综合评价的结果为:优级品种12个,占17.39%;良级品种16个,占31.88%;中级品种19个,占33.33%;差级品种12个,占17.39%。12个优级多花型园林小菊品种分别为‘钟山金阳’‘钟山光辉’‘钟山赤焰’‘钟山早白’‘钟山银桂’‘钟山敷粉’‘钟山紫瑞’‘钟山樱桂’‘钟山紫鹃’‘钟山紫松果’‘钟山紫辰’‘钟山紫日’。冠丛圆整性、花朵繁密度、花朵数量、花色持久度、花期长度、植株紧凑性、缺株数等是多花型园林小菊品种的重要品质评价指标。[结论]层次分析法可有效地应用于多花型园林小菊综合评价和品种筛选。[Objectives]The ornamental quality,plant growth characteristics and adaptability were investigated to establish a comprehensive evaluation system for the quality of multi-flower garden chrysanthemum,with an intention of providing a reference for the selection and introduction of new varieties.[Methods]Based on the main quality traits observed in a panel of 69 multi-flower garden chrysanthemum varieties for two consecutive years,a comprehensive quality evaluation system was set up by using the three methods of expert consultation,analysis of hierarchy process and K-Means clustering.[Results]Comprehensive evaluation assigned the 69 multi-flower garden chrysanthemum varieties into four grades,12 excellent varieties（17.39%）,16 good-grade varieties（31.88%）,19 medium-grade varieties（33.33%）,and 12 poor-grade varieties（17.39%）.The 12 excellent varieties were‘Zhongshanjinyang ＇‘Zhongshanguanghui＇ ‘Zhongshanchiyan＇ ‘Zhongshanzaobai＇ ‘Zhongshanyingui＇ ‘ Zhongshanfufen＇ ‘ Zhongshanzirui ＇‘Zhongshanyinggui＇‘Zhongshanzijuan＇‘Zhongshanzisongguo＇‘Zhongshanzichen＇and‘Zhongshanziri＇.Crown roundness,numerous density of flower,flower number,color persistency,flowering duration,plant compactedness and number of dead plant were considered to be the major evaluation indicators.[Conclusions]Analytic hierarchy process（AHP） can be effectively used incomprehensive in evaluation and selection of multi-flower garden chrysanthemums.
