An efficient regeneration protocol for Phyllanthus niruri was developed using nodal explants on MS medium augmented with different concentrations and combinations of plant growth regulators. The highest frequency (85.5%) of bud break and shoot induction was observed on medium supplemented with 1.0 mg/l BAP along with 0.5 mg/l IBA with the formation of 4.2±0.5 number of shoots having length of 3.0±0.1 centimeters within ten days. MS medium fortified with 1.0 mg/l BAP and 1.0 mg/l Kinetin in

Shoots formed were remarkable healthy and achieved the length of 10.0±0.5 centimeters in 25 days. Elongated shoots were rooted best on MS medium with 1.0 mg/l IBA producing maximum number of roots with 85% response with average length 8.0±0.3 cm within 15 days. The plantlets were gradually acclimatized and successfully transferred to field condition with 98% survival rate after rooting. The standardized protocol reported in this study may help in large scale propagation of this plant species which is currently exploited from the nature.
