摘　　要：本研究旨在探索一种简便易行的菊花综合评价方法,用于筛选适合郑州栽培的菊花品种。采用灰色关联法、相关性分析、主成分分析等方法对8个菊花品种的9个农艺性状进行了深入分析。结果表明,菊花品种的9个农艺性状均存在差异,变异系数为6.07%~34.42%。灰色关联度分析得出,菊花产量与其他8个性状关联度从高到低为分枝数>花朵数>冠幅>株高>单花鲜重>叶长>花径>叶宽,说明菊花育种和引种中应重点关注分枝数、花朵数、冠幅3个农艺性状指标。主成分分析中,得分第1名为‘婺源皇菊’与鲜菊花产量第1名一致,主成分前4名与鲜菊花产量前4名品种一致。基于主成分分析和灰色关联度构建出的综合评价方法可以有效进行评价,筛选出的‘婺源皇菊’、‘金丝皇菊’、‘怀黄菊1号’和‘怀白菊’等品种可以在郑州及周边地区推广应用。In order to explore a simple and feasible comprehensive evaluation method of Chrysanthemum morifolium,and select suitable C.morifolium varieties for cultivation in Zhengzhou,C.morifolium varieties were used as test materials,the comprehensive evaluation of 9 agronomic traits was carried out using grey correlation degree,correlation analysis and principal component analysis.The results showed that 9 agronomic traits of C.morifolium varieties were different,and the coefficient of variation was 6.07%-34.42%.According to the analysis of the gray correlation,the correlation between each agronomic trait and C.morifolium yield was as follows:branch number>flower number>crown width>plant height>fresh weight of single flower>leaf length>flower diameter>leaf width.The results indicated that the number of branches,the number of flowers and the width of crown should be paid attention to in the breeding and introduction of C.morifolium.The results of principal component analysis showed that the first highest score of C.morifolium‘Wuyuanhuangju’was consistent with the first highest yield of fresh C.morifolium,and the top four highest scores of principal component analysis were consistent with the top four highest yield of fresh C.morifolium.Therefore,the comprehensive evaluation method based on principal component analysis and grey correlation degree can be effectively evaluated,the selected varieties of C.morifolium‘Wuyuanhuangju’,C.morifolium‘Jinsihuangju’,C.morifolium‘Huaihuang’and C.morifolium‘Huaibai’can be popularized and applied in Zhengzhou and its surrounding areas.
