摘　　要：目的:建立优良杜鹃切花资源综合价值评价体系,筛选出适宜江苏地区种植推广的切花杜鹃,为杜鹃资源的合理利用提供参考依据。方法:以50种杜鹃(品种和野生种)为材料,采用层次分析法(AHP)筛选适合江苏地区露地栽培的优良杜鹃切花,并运用平衡不完全区组设计-比较评判法(BIB-LCJ)对大众喜爱的杜鹃切花花色进行综合分析。结果:约束层权重计算中,观赏特性的权重最高(0.6184),标准层14个指标中,花色C5、花型C9与瓶插寿命C14的权重值较大,叶片观赏性C11权重最低。使用BIB-LCJ法进行综合分析得出受大众喜爱度在前十名的杜鹃花色为白、浅粉、蓝紫、黄、红色系,喜爱程度一般的花色则集中在稍深色系和橙黄色系;最后五名则集中在深红、深橙红、红紫等暗淡色系。结论:筛选出Ⅰ级杜鹃切花‘西子妆’‘大鸳鸯锦’和‘玉飞燕’等10种,这些品种均具有花色淡雅、瓶插寿命长和枝条抽生能力强等特点,可以作为杜鹃切花生产的优先考虑对象推广应用。通过AHP法和BIB-LCJ法构建的杜鹃切花综合评价体系为杜鹃切花生产和切花新品种的选育提供了有力指导。Objective:To establish a comprehensive value evaluation system for excellent cut Rhododendron resources,screen out the varieties and wild species suitable for planting and promotion in Jiangsu,and provide reference basis for the rational utilization of Rhododendron resources.Methods:Taking 50 species of Rhododendrons(cultivars and wild species)as materials,the analytic hierarchy process(AHP)was used to screen out excellent cut Rhododendrons suitable for open-field cultivation in Jiangsu region.And the balanced incomplete block design-low of comparative judgement(BIB-LCJ)method was applied to conduct a comprehensive analysis of the popular flower colors of cut Rhododendrons.Results:In the weight calculation of the constraint layer,the ornamental characteristics had the highest weight(0.6184).Among the 14 indicators of the standard layer,the flower color(C5),flower form(C9)and vase life(C14)had relatively large weight values,while the weight of the ornamental(C11)value of leaves was the lowest.The comprehensive analysis using BIB-LCJ evaluation method demonstrated that the top ten popular flower colors of Rhododendrons were white,light pink,blue-purple,yellow and red.The flower colors with moderate popularity were concentrated in slightly darker and orange-yellow colors.The last five were concentrated in dark colors such as deep red,deep orange-red,and red-purple.Conclusion:With the characteristics of light and elegant flower color,long vase life and strong branching ability,the ten first-class cut Rhododendrons such as‘Xi Zizhuang’‘Da Yuanyangjin’and‘Yu Feiyan’can be promoted and applied as priority objects for cut Rhododendron production.Furthermore,the comprehensive evaluation system of cut Rhododendrons constructed by AHP and BIB-LCJ methods provided strong guidance for the production of cut Rhododendrons and the breeding of new cut flower varieties.
