摘要: 【目的】建立多头切花菊品质综合评价综合体系,为快速筛选优良品种和新品种引进与选育提供技术支撑。【方法】2009年和2010年通过大田试验对收集保存的160个多头切花菊品种主要品质性状进行观察统计,并应用专家咨询法、层次分析法和K-Means聚类法建立评价体系。【结果】应用专家咨询法并结合其它观赏植物评价体系,筛选出11个对多头切花菊品质性状影响较大的因子。应用层次分析法对各影响因子的权重进行定量评价,其中株型对多头切花菊品质影响最大,其权重为0.228;花色次之,其权重为0.150;分枝长度居第3位,其权重为0.132。对160个多头切花菊品种进行聚类分析的结果为,优等级品种41个,占25.63%;良等级品种71个,占44.38%;中等级品种35个,占21.88%;差等级品种13个,占8.13%。【结论】品种评价结果与实际生产经验相符,表明应用专家咨询法、层次分析法和K-Means聚类法建立的评价体系可以很好地对多头切花菊品种进行评价和分级。

Abstract: 【Objective】The present study was to establish a synthetic system for assessing the quality of spray cut chrysanthemum, and to offer technological support for selecting, introducing, and cross breeding of spray cut chrysanthemum.【Method】Field experiments were conducted to observe and count quality factors of 160 varieties of spray cut chrysanthemum in 2009 and 2010. A synthetic assessing system was established by means of expert consultation, analytic hiberarchy process and K-Means cluster method.【Result】The factors affecting the quality of spray cut chrysanthemum were analyzed, and 11 factors were selected. The weight of the 11 factors was quantitatively evaluated by analytic hierarchy process. Plant character, flower color and branch length had the most important effect, and weight was 0.228, 0.150, and 0.132, respectively. One hundred and sixty varieties of spray cut chrysanthemum were then clustered into 4 grades by K-Means cluster method. There were 41 varieties graded excellent, 71 graded good, 35 graded moderate and 13 graded poor,the occupancy was 25.63%, 44.38%, 21.88% and 8.13%, respectively.【Conclusion】The evaluation result was consistent with production practice, and the system constructed by adopting expert consultation, analytic hiberarchy process and cluster method can be used to evaluate and classify for spray cut chrysanthemum varieties.
