Abstract:

To explore the genetic relationship of Leonurus japonicus germplasm resources from different origins and their agronomic traits and medicinal quality performance,this study analyzed the diversity of 64 wild Leonurus japonicus germplasm resources from different origins through SRAP labeling,investigated the agronomic traits of Leonurus japonicus at different periods,and detected its characteristic components based on high performance liquid chromatography (HPLC). The results showed that the genetic similarity coefficients of 64 wild germplasm resources were relatively high,but there was genetic differentiation among the germplasm resources,and the degree of genetic differentiation among populations showed a correlation with geographical distance. In addition,the quality of Leonurus japonicus varied greatly from region to region. However,the superior varieties selected in the current year could maintain their quality advantages in the following year. Besides,the agronomic traits and quality of Leonurus japonicus harvested in the current year had a certain correlation with the quality of Leonurus japonicus harvested in the early flowering stage of the following year,which can provide a reference for the quality identification and breeding of Leonurus japonicus.
