Abstract: In order to screen out high‑yield，high‑quality，and stable excellent germplasm of Corydalis yanhusuo and promote the sustainable development of the industry，the bulbs of Corydalis yanhusuo from Zhejiang，Anhui，Shaanxi and Henan provinces were planted in the Corydalis yanhusuo planting base in Zhuqu Town，Weishi County，Henan Province.They were continuously planted for two years in the same plot from 2021 to 2023.The agronomic traits such as growth indicators，disease index and yield of Corydalis yanhusuo，as well as the conventional test items in Chinese Pharmacopoeia and the content of tetrahydropalmatine were determined.There were no significant differences in plant height and leaf number among the four provenances（P>0.05）.The yield of Zhejiang provenance was significantly higher than that of Anhui and Henan in two consecutive seasons（P<0.05）.The germplasms with lower disease index were Zhejiang and Shaanxi，and the disease index of Shaanxi provenance decreased after continuous planting.The medicinal materials of four Corydalis yanhusuo provenances all met the regulatory standards of Chinese Pharmacopoeia.The alcohol soluble extracts and tetrahydropalmatine contents of Zhejiang and Shaanxi germplasm sources were superior to those of Anhui and Henan germplasm sources. In summary，it is believed that the two Corydalis yanhusuo germplasm resources from Zhejiang and Shaanxi are suitable for planting in Weishi area of Henan Province.
