摘　　要：【目的】为满足长沙花卉市场对观赏百合的需求,筛选出适合在长沙地区栽培的优质百合资源。【方法】本研究应用层次分析法从栽培表现、观花性状、株型特征3个方面进行植株的表型性状调查,对引种的18个百合种及品种进行观赏性状综合评价。通过对一级指标(栽培表现、观花性状、株型特征)和二级指标(10个性状指标)分别进行赋权,最终确定10个性状指标的权重值,并对其数据进行主成分分析和聚类分析。【结果】根据赋权得分,病虫害及迫害情况、花色及斑点、叶密集程度、花着生姿态等性状权重所占比重较大,分别为0.6814、0.5860、0.5907、0.2180。基于此获得18个百合种及品种的观赏性状综合评价,并将这些植物划分为Ⅰ、Ⅱ、Ⅲ三个等级,该分级情况与主成分分析和聚类分析结果一致。【结论】根据18个百合种及品种观赏性状综合评分结果,‘Secret Kiss’、‘红妆’、新铁炮百合和‘金百合橙’4个Ⅰ级品种栽培表现和观赏性状优异,可作为优良品种在湖南长沙地区推广。【Objective】To meet the demand for ornamental lilies in Changsha flower market,we screened out high-quality lily resources suitable for cultivation in Changsha.【Method】In this study,we applied the analytic hierarchy process(AHP)to adjust the performance traits of plants from three aspects,namely,cultivation performance,flower-viewing traits,plant characteristics,and comprehensively evaluated the ornamental traits of 18 lilies introduced.By assigning weights to the primary indicators(cultivation performance,flower-viewing traits,plant characteristics)and secondary indicators(10 trait indicators),the weights of the 10 trait indicators were finally determined,and the data were analyzed using principal component analysis and cluster analysis.【Result】According to the weighted scores,the traits with the highest weights were pest and damage resistance,flower color and mottling,leaf density,and flower posture,with respective weights of 0.6814,0.5860,0.5907,0.2180.Based on these results,the 18 lily varieties were categorized into three levels:Ⅰ,Ⅱ,andⅢ,which was in line with the results of principal component analysis and cluster analysis.【Conclusion】Based on the results of the comprehensive scoring of the ornamental value of 18 lily varieties and species,the four Class I varieties,‘Secret Kiss’,‘Red Made-up’,Lilium×formolongi,and‘Golden Lily Orange’,have excellent cultivation performance and ornamental traits and can be promoted as excellent varieties in Changsha,Hunan.
