党参属种质资源多样性及可药用种质创新研究进展

桔梗科党参属Codonopsis植物全球约40种，《中国药典》2020年版仅收录党参、素花党参和川党参。党参属野生药用植物资源稀少，药材以栽培品为主。因党参需求量大，连作重茬较为普遍，种子种苗流通及全球气候变暖交融因素加速了党参种质资源性状多元化，种性混杂退化使党参根部病害加重、产量和质量降低，严重制约党参大健康产业的可持续化发展。通过文献查阅，在资源调查和田间试验基础上，对党参属植物分布、多样性、种质提纯及创新现状进行系统概述，旨在引导党参资源利用和加快新品种选育进程。

Research progress on diversity of Codonopsis genus resources and innovation of medicinal germplasm

There are about 40 species of Codonopsis genus in the family Platycodonaceae worldwide. The Chinese Pharmacopoeia only includes Dangshen (Codonopsis pilosula), Suhua Dangshen (Codonopsis pilosula var. modesta), and Chuandangshen (Codonopsis tangshen). Codonopsis genus wild medicinal resources are scarce, and Dangshen (Codonopsis Radix) is mainly cultivated. Due to the high demand for Codonopsis Radix, continuous cropping and heavy cropping are more common. Seedling circulation and global warming have accelerated the diversification of traits in the resources of Codonopsis Radix. Mixed and degraded species lead to increase the root diseases, and reduce yield and quality of Codonopsis Radix, which seriously restrict the sustainable development of the health industry of Codonopsis Radix. This paper provides a systematic overview of the distribution, diversity, germplasm purification and innovation status of Codonopsis genus based on a literature review, resource investigation and field trials, aiming at guiding the use of resources and accelerating the process of selection and breeding of new varieties.
