An efficient protocol was developed for in vitro propagation of Abrus precatorius L. through induction of indirect organogenesis in nodal segment derived callus tissue. Yellowish-green nodular callus was induced at the cut surface of the nodal segments cultured on MS fortified with 5.0 mg/l BAP and 0.5 mg/l NAA. The callus differentiated into adventitious shoots when it was subcultured on to MS supplemented with 3.0 mg/l BAP + 0.5 mg/l Kn + 0.5 mg/l NAA. On an average 6.87 ? 0.26 shoots/culture developed. These microshoots were rooted in half-strength MS containing 1.0 mg/l IBA and the rooted plantlets were transferred to soil after proper acclimatization.
