title: [Comparison on agronomy and quality characters and breeding of new strains of Erigeron breviscapus].
abstract: OBJECTIVE
  To explore breeding method and breed new varieties of Erigeron breviscapus.
  
  
  METHODS
  Superior individual were selected from natural outcrossing population of E. breviscapus, lines and strains were established and selected and compared.
  
  
  RESULTS
  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%.
  
  
  CONCLUSIONS
  New varieties of E. breviscapus can be bred through lines breeding.
