A reliable protocol has been established for in vitro propagation of Artemisia nilagirica var. nilagirica (Indian wormwood), a valuable medicinal plant from India. A highly proliferating organogenic callus was obtained on Murashige and Skoog (MS) medium supplemented with 2.5 lM IAA when nodal explants were cultured on MS medium supplemented with various growth regulators. Further, highest regeneration frequency (83.3 %) of adventitious shoots was observed, when the callus was subcultured on MS medium supplemented with 6-benzylaminopurine (BAP; 2.5 lM) along with 7.5 lM 2-isopentenyl adenine (2-iP). An optimal of 10.16 ± 2.24 shoots were regenerated on medium supplemented with 2.5 lM BAP ? 7.5 lM 2-iP. Quarter strength MS medium supplemented with 10 lM IBA was effective for rooting of the shoots. Ex-vitro plants were normal and were established successfully. Cytological and molecular marker studies showed that regenerated plants showed genetic stability in micro-propagated plants.
