Comprehensive evaluation on herbaceous peony resources introduced in Suqian City

【目的】建立芍药品种的综合评价体系,筛选出适宜在江苏省宿迁市露地栽培的芍药品种,为芍药大规模引种及园林应用提供参考。【方法】以104个芍药品种为试验材料,采用层次分析法(AHP)从适应性、植株特性和观赏性3个方面,对11个关键性状指标进行定量评价。【结果】适应性的权重最大,为0.5390,比植株特性和观赏性更重要。104个芍药品种共分为4个等级,紫金莲、赛富贵、紫凤羽等12个品种为Ⅰ级优秀,推荐在宿迁市优先应用;大红袍、黄羽球、少女装等45个品种为Ⅱ级良好,可保守应用;粉刺金鱼、胭脂红、曹州红等29个品种为Ⅲ级,可适当应用;铁杆紫、昆山霞光、鲁西红等18个品种为Ⅳ级,不适合在宿迁市开发利用。【结论】从104个芍药品种中筛选出紫金莲、赛富贵、紫凤羽、红艳遇春、星光灿烂、芙蓉绒花、鸡冠紫、兰重梦、水映春兰、银线绣红袍、莲台子和美菊12个适宜在江苏省宿迁市露地栽培的品种。

【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 0.5390,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 GradeⅠ,superior,and were recommended for preferentially application in Suqian City.45 cultivars,including Dahongpao,Huangyuqiu,and Shaonnyuzhuang,were at GradeⅡ,fine,could be used conservatively.29 cultivars were at GradeⅢand could be used appropriately,including Fencijinyu,Yanzhihong,and Caozhouhong.18 cultivars,including Tieganzi,Kunshanxiaguang and Luxihong were evaluated as GradeⅣand 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.
