The purpose of this study was to develop an efficient micropropagation system for Mucuna pruriens, an important medicinal plant in India. A range of cytokinins was investigated for multiple shoot regeneration with cotyledonary node explants from 7-d-old aseptic seedlings. Of all the cytokinins, 6-benzyladenine (BA), kinetin (KIN) and 2-isopentenyl adenine (2-iP) tested in Murashige and Skoog medium (MS), BA was the most effective and 5.0 μM was found to be optimum for inducing maximum shoots. Medium types, medium strength and pH were also investigated for induction and proliferation of shoots. The highest efficiency of shoot proliferation was observed in 5.0 μM BA and 0.5 μM α-naphthalene acetic acid (NAA) in half-strength MS medium at pH 5.8. The best condition for rooting was half-strength MS medium solidified with agar and with 2.0 μM indole-3-butyric acid (IBA). After rooting, the plantlets were transferred to plastic pots filled with sterile soilrite where 90% grew and all exhibited normal development.
