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.

摘要： 为筛选出高产、质优、稳定性强的延胡索优良种质，促进延胡索产业的可持续发展，将来自浙江省、安徽省、陕西省、河南省的4个种源延胡索种植于河南省尉氏县朱曲镇延胡索种植基地，于2021—2023年在同一地块连续种植2 a，测定延胡索的生长指标、病情指数、产量等农艺性状，以及《中国药典》规定的药材质量性状。结果表明，4个种源的株高、叶片数没有显著差异（P>0.05）；浙江省种源延胡索的产量连续2季均显著高于安徽省、河南省（P<0.05）；块茎腐烂病病情指数较低的是浙江省和陕西省种源，且陕西种源连续种植后病情指数有所降低；4个种源的药材均符合《中国药典》有关延胡索的规定标准，浙江省和陕西省种源醇溶性浸出物及延胡索乙素含量均优于安徽省及河南省种源。综上，来源于浙江和陕西的2份延胡索种源适宜在河南省尉氏县种植。
