摘要: 【目的】建立国庆小菊观赏性和耐旱、涝性的综合评价体系,为品种的筛选与推广应用提供理论依据。【方法】通过田间和盆栽试验对20个国庆小菊品种的22个观赏性和耐旱、涝性指标进行观测统计,应用层次分析法建立综合评价体系,运用K-Means聚类法划分品种等级。【结果】筛选出22个与国庆小菊观赏性和耐旱、涝性密切相关的评价因子,并确定了各因子最终的综合权重值;依据评分标准对20个品种评分,乘以各因子的权重得出各品种的综合分值;利用最小距离法并根据各等级国庆小菊性状综合得分的聚类中心值划分为优、良、一般3个等级,各级品种个数分别为5、11和4,所占比例分别为25%、55%和20%。【结论】应用层次分析法和K-Means聚类法建立的综合评价体系可以较好地对国庆小菊品种进行评价和分级,最终筛选出5个等级为优、11个等级为良的品种,可用于大面积的推广应用。

Abstract: 【Objective】 The present study was to establish a synthetic system for assessing the ornamental values and drought and flooding resistance of Guoqing chrysanthemum with small inflorescences, and to offer a theoretical support for selection, extension and application. 【Method】 Field and pot-culture experiments were conducted to observe and count 22 indexes of the ornamental values and drought and flooding resistance of 20 Guoqing chrysanthemum varieties with small inflorescences. A synthetic system was established by using analytic hiberarchy process and the K-Means clustering method was applied to differentiate the rank of cultivars.【Result】Twenty-two evaluating factors closely related to ornamental values and drought and flooding resistance were selected and the weight of each affecting factor was calculated. According to the rating criteria, 20 cultivars were endowed with different scores and then multiplied the weight of each factor to obtain the comprehensive score of each cultivars. Finally by K-Means cluster method, using minimum distance method and the clustering center value of synthetical scores of Guoqing chrysanthemum with small inflorescences of various ranks, 20 cultivars were clustered into 3 grades: excellent, good, and general. There were 5, 11 and 4 cultivars in the three grades, and amounted for 25%, 55%, and 20%, respectively. 【Conclusion】 The system constructed by adopting analytic hiberarchy process and cluster method can be used to evaluate and classify small chrysanthemum cultivars. Finally 5 excellent and 11 good cultivars were selected and can be extended in lager areas.
