野生牡丹种质资源现状及保护建议

Current status of wild tree peony germplasm resources and suggestions for their conservation

野生牡丹为中国特有植物,是培育优异牡丹品种的重要资源。针对野生牡丹资源破坏严重,多数野生种处于濒危状态的现状,基于文献调研、原生境实地考察、电话咨询及团队对野生牡丹长期繁育的研究,总结了野生牡丹分类、目前分布区域和存在数量及其在育种中的应用。同时,综述了野生牡丹起源进化和油用与食用价值开发等方面研究进展,结合野生牡丹收集保存的现状和本团队野生牡丹研究进展,提出了具体保护策略。

Tree peonies are deciduous subshrubs in the Paeonia section of Moutan from the Paeoniaceae and include nine wild species and one cultivated specie with more than one thousand cultivars.All of tree peony wild species are native to China,and they are the important parental resources for excellent variety breeding of tree peony.In view of severely damaged and endangered status of wild tree peony species,based on the reference of literatures,investigation of their original habitat,telephone consulting,and team research findings about wild tree peony species,we summarized the classification,current distribution regions and numbers of wild species,and its application in genetic breeding of tree peony.In addition,we reviewed the contribution of wild species on phylogenetic evolution of tree peony,and the development of their oil and edible value.Finally,according to the current status of collection and conservation of wild species and research progress of wild species in our team,we summarized the conservation strategies of wild tree peony species and it provides reference for conserving wild tree peony species in the future.
