Objectives To obtain the variety of Erigeron breviscapus with high yield, high content of active constituents, and stable agronomic characteristics. Methods The group bulk selection breeding and individual selection breeding methods were applied respectively, and two varieties were evaluated partially by DUS testing and the fingerprint was analysed by AFLP markers. Results The variety “Airuijie No. 1” had the yield of 3 780 kg/hm2, the scutellarin content of 1.84 %, and the total caffeic acid esters content of 1.79 %; For the other variety “Airuijie No. 17”, the yield was 3 075 kg/hm2, the content of scutellarin was 1.71 %, and the content of total caffeic acid esters was 1.50%. Compared with the wild local E. breviscapus after one-year acclimatization, the two new varieties showed better economic traits with higher uniformity, more stability, and unique AFLP fingerprint. Conclusion The two varieties of E. breviscapus have high value of application and popularization.
