An efficient plant regeneration protocol was developed for Artemisia annua, an aromatic medicinal herb. Nodal explants inoculated on MS supplemented with 4.44 ?M BAP showed better growth response and produced 116.2 ? 0.1 micro-shoots of an average length 1.9 ? 0.3 cm after 35 days culture. The cluster of small shootlets were cultured on shoot elongation medium supplemented with 1.44 ?M GA3 and 10% coconut milk (CM) showed shoot elongation up to 4.6 ? 0.7 cm. Roots were induced after transfer to half strength MS supplemented with 2.46 ?M IBA produced 14.3 ? 0.2 roots with an average height of 4.3 ? 0.53 cm after 30 days. The rooted plantlets were transferred for hardening, 80 per cent of plantlets survived and resumed growth in the mixture of soil, vermiculite and farm yard manure (1 : 1 : 1).
