Abstract: The rapid propagation medium for virus-free plantlets of Dioscorea bulbifera were studied by orthogonal design,and the effects of rapid propagation medium including different concentrations of KT,NAA and 2,4-D on rapid propagation of Dioscorea bulbifera were also investigated.The results showed that the best rapid propagation medium for virus-free plantlets of Dioscorea bulbifera was MS+KT 2.0 mg/L+NAA 0.5 mg/L.
