Abstract:
Taking 106 Codonopsis resources from 13 provinces and cities as the test materials,the genetic relationship of 106 Codonopsis germplasm resources was studied by the combination of plant morphological characteristics and DNA molecular identification,in order to provide reference for identifying Codonopsis germplasm resources by DNA barcoding combined with plant morphological characteristics.The results showed that there were significant morphological differences among C.pilosula （Franch.） Nannf., C.tangshen Oliv.,C.pilosula Nannf.var.modesta （Nannf.） L.T.Shen as well as C.tubulosa,C.lanceolata.Differences between C.pilosula （Franch.） Nannf., C.tangshen Oliv.and C.pilosula Nannf.var.modesta （Nannf.） L.T.Shen were smaller，but all could be identified by plant morphological differences.ITS2 and psbAtrnH sequences accurately identified C.pilosula （Franch.） Nannf., C.tangshen Oliv.,C.pilosula Nannf.var.modesta （Nannf.） L.T.Shen as well as C.tubulosa,C.lanceolata.However，limitations were encountered in identifying variant species among the original variants.
