Rhynchostylis retusa, a monopodial orchid is important for both its medicinal and economic values. Different parts like shoot, leaf and root were used as explants for micropropagation of Rhynchostylis retusa. The explants were cultured in Vacin and Went (VW), Knudson C and Nitsch media supplemented with sucrose (20 g L-1) and growth regulators, viz., NAA (0.1 mgL-1), BAP (1.0 mgL-1) and Kinetin, Kn (0.4-1.0 mgL-1) in different concentrations and combinations. Green protocorm-like bodies (PLBs) and calli which later differentiated into plantlets were induced from shoot-tip, leaf and root-tip explants using VW medium supplemented with NAA (0.1 mgL-1) along with either Kinetin (1.0 mgL-1) or BAP (1.0 mgL-1). Maximum survival as well as differentiation was obtained from shoot-tip explants. Further growth and development of PLBs into plantlets were achieved when cultured in VW medium with gradual removal of NAA and reduction of Kinetin and BAP concentrations. Transplantation in community pots could be done when the plantlets were 3.0-3.5 cm. These results suggest a methodology for in vitro mass propagation of Rhynchostylis retusa.
