摘　　要：目的比较研究各益母草种质资源的差异性,为品种选育提供优良育种材料。方法将收集自全国不同产地的20个野生益母草种质资源在浙江衢州进行同质园试验,观察其物候期、耐寒性及生境适宜性;测定初花期株高、鲜重和干重,并分别测定初花期和反季节栽培的益母草植株中盐酸水苏碱和盐酸益母草碱含量。结果综合各种质对浙江生境的适应性、初花期药材干产量及其中的盐酸水苏碱和盐酸益母草碱成分含量、反季节栽培益母草植株中上述2种成分的含量水平,河南灵宝、河南社旗和湖南桂东3个种质较好,其中以河南灵宝种质最佳,其初花期药材干产量(30.6 g/株)、初花期植株中盐酸水苏碱和盐酸益母草碱含量(分别为1.31%和0.19%)及反季节栽培植株中有效成分盐酸水苏碱和盐酸益母草碱含量(分别为3.44%和0.37%)均较高,且能适应在浙江种植。结论河南灵宝种源可以作为品种选育的最佳候选材料。Objective To study the difference ofLeonurus japonicus germplasm resources and provide good materials for breeding.Methods Totally 20 wildLeonurus japonicus germplasm resources from different places of China were collected. Experiment was conducted in homogeneous garden in Quzhou City of Zhejiang Province. Phenological phase, cold endurance and habitat adaptability were observed; the plant height, fresh weight and dry weight in early flowering were measured; the contents of stachydrine hydrochloride and leonurine hydrochloride were determined in early flowering and out-of-season cultivation.Results Considering the habitat adaptability, dry plant weight in early flowering, the contents of stachydrine hydrochloride and leonurine hydrochloride separately in early flowering and out-of-season cultivation, it was believed that the germplasms from Linbao County, Sheqi County in Henan Province and Guidong County in Hunan Province were better, in which Linbao germplasm was the best: the dry plant weight was 30.6 g, the content of stachydrine hydrochloride and leonurine hydrochloride were 1.31% and 0.19% respectively in early flowering, and were 3.44% and 0.37% respectively under anti-season cultivation, and it can be well adapted in Zhejiang Province.Conclusion The germplasm ofLeonurus japonicas from Lingbao can be the best materials for breeding.
