Abstract:

【Objective】To establish a comprehensive evaluation system of herbaceous peony cultivars,screen cultivars suitable for outdoor cultivation in Suqian City,Jiangsu Province,and provide reference for large-scale introduction and landscape application of herbaceous peony.【Methods】Using 104 herbaceous peony cultivars as the experimental materials,the quantitative evaluation of 11 key traits was carried out from three aspects,adaptability,plant characteristics and ornamental quality by analytic hierarchy process(AHP).【Results】The weight of adaptability was the largest at 0.539 0,which was more important than plant characteristics and ornamental. 104 cultivars were divided into four grades. 12 cultivars,including Zijinlian,Saifugui and Zifengyu,were at Grade Ⅰ,superior,and were recommended for preferentially application in Suqian City. 45 cultivars,including Dahongpao,Huangyuqiu,and Shaonnyuzhuang,were at Grade Ⅱ,fine,could be used conservatively. 29 cultivars were at Grade Ⅲ and could be used appropriately,including Fencijinyu,Yanzhihong,and Caozhouhong. 18 cultivars,including Tieganzi,Kunshanxiaguang and Luxihong were evaluated as Grade Ⅳ and deemed unsuitable for development and utilization in Suqian City.【Conclusion】12 herbaceous peony cultivars including Zijinlian,Saifugui,Zifengyu,Hongyanyuchun,Xingguangcanlan,Furongronghua,Jiguanzi,Lanchongmeng,Shuiyingchunlan,Yinxianxiuhongpao,Liantaizi and Meiju were selected out of 104 cultivars as being suitable for outdoor cultivation in Suqian City,Jiangsu Province.
