Abstract: Shoot tip, nodal and internodal segments of Phyllanthus amarus Schum. & Thonn. were cultured on Murashige and Skoog (MS) medium supplemented with different concentrations of 6-benzyl amino purine (BAP) and kinetin (Kn) with 15% coconut milk. All the explants responded for regeneration. High frequency (100%) and maximum number of shoots (18.30 ± 0.47) were recorded on medium containing BAP (0.5 mg/l) in shoot tip culture. In vitro shoots were excised from shoot clumps and transferred to rooting medium containing different concentrations of indole butyric acid (IBA) or naphthalene acetic acid (NAA). Maximum number of roots was induced in medium containing IBA (0.5 mg/l). Rooted plantlets were hardened on MS basal liquid medium and subsequently in sterile soil + vermiculite (1:1). Plantlets thus developed were successfully established and finally transferred to greenhouse. The survival rate of the plantlets in the field was found to be very high (85%).
