For conservation and genetic transformation, a successful in vitro micropropagation protocol for Ajuga bracteosa, a medicinal herb has been established for the first time. MS medium supplemented with IAA (2 mg/L) and BA (5 mg/L) induced 100 % shoot regeneration with an average of 41.4 shoots of 8.4 cm per culture. Excised in vitro shoots when transferred to MS + IBA (0.5 mg/L) produced 20 roots/shoot of 20.2 cm average length in 100 % cultures. Of the three explants, leaf, petiole and root, leaf displayed quickest response followed by petiole while root was the slowest. Hardening of plantlets was achieved with 82 % survival. The hardened plants were maintained in pots with garden soil under controlled (Temp. 25 +/- 2 A degrees C) conditions. RAPD exhibited genetic fidelity with 100 % monomorphism in regenerants.
