Dioscorea panthaica Prain et Burkill is a traditional Chinese herb and field cultivation as the major source of this plant becomes hard to meet the increasing demand in the market. Moreover, the propagation through rhizome is both costly and causing low yield and poor quality. Here, in order to providing commercial grade seedlings through in vitro propagation, we have studied callus formation, organ differentiation and plantlet regeneration. The in vitro establishment and propagation of mature D.panthaica plant were firstly reported in present paper. Our results suggested that leaves were the best explants for callus induction, and the optimal medium were as followed: MS with 2.0 mg/L 2,4-D and 2.0 mg/L BA for callus induction; MS with 1.0 mg/L BA, 0.5 mg/L NAA, 2% sucrose at pH 6.4 for shoot differentiation; and MS with 0.5 mg/L BA, 0.1 mg/L NAA, 3% sucrose at pH 6.8 for root formation.
