Micropropagation ofAbelmoschus esculentusL. (Moench.) for disease free plantlets through meristem culture

Protocol was established for mass in vitro propagation of okra using meristem culture. Meristems (0.3–0.5 mm in size) were isolated from shoot tips of three-week old in vitro grown seedlings. Isolated meristems were established rapidly in MS liquid medium containing 1.0 mg/l of BAP. For shoot development from primarily established meristem, semisolid MS medium having the same concentration of BAP was found to be the most effective. Rapid shoot multiplication of mericlone was achieved from node cutting cultured in 1.0 mg/l plus 0.5 mg/l GA3, and a maximum of nine shoots were found from each node. Effective root development from the developed plantlets was successful in 1.0 mg/l IBA. More than 75% of the micropropagated mericlones plantlets were successfully acclimatised in soil up to maturity and found to be healthy.
