OBJECTIVE: To explore breeding method and breed new varieties of Erigeron breviscapus. METHOD: Superior individual were selected from natural outcrossing population of E. breviscapus, lines and strains were established and selected and compared. RESULT: The scutellarin contents of two E. breviscapus strains of 2003-15 and 2003-6 through line breeding were 3.21% and 3.01%, respectively, and increased 15.77% and 23.46% comparing with the control strain (QS-1), respectively, the yield increased 20.37% and 17.59%, scutellarin yield per hectare enhanced 39.31% and 44.82%. CONCLUSION: New varieties of E. breviscapus can be bred through lines breeding.
