[Objective] To compare the growth and development traits of Asarum heterotropoides Fr.Schmidt var.mandshuricum(Maxim.) Kitag of different strains,so as to breed new variety.[Method] The growth traits were investigated by determining the fresh weight of single plant,fresh weight of root,developing shoot amount of Beixi01,Beixi02 and Beixi03,as well as the content of volatile oil in them.[Result] The yield and volatile oil content of each strain increased the most quickly in the fifth growth year.Beixi03 strain was of good yield and growth capacity,which was superior to Beixi01 and Beixi02,whereas the content of volatile oil in it was lower than that in Beixi02.The content of volatile oil in 5-year old Asarum heterotropoides Fr.Schmidt var.mandshuricum(Maxim.) Kitag attained the critical content that ruled in Chinese Pharmacopoeia(2005 Edition),and that in 6 years old ones was higher than that ruled in Chinese Pharmacopoeia.[Conclusion] Beixi03 strain is the more favorable strain of Asarum heterotropoides Fr.Schmidt var.mandshuricum(Maxim.) Kitag and is expected to be a new variety of Asarum heterotropoides Fr.Schmidt var.mandshuricum(Maxim.) Kitag.
