Abstract : Axillary shoot multiplication from shoot bud segments collected from the superior about  15 year old Pongamia pinnata(Karanj) tree were tried . Pongamia pinnata axillary bud explants receiving 2.0mg/l BA gave the height response as far as individual cytokinins are concerned . In such cultures shoots varying from 3 to 5 numbers were produced at an average of 3.0±1.62 per plant. Shoots formed in vitro were rooted on full-strength MS medium supplemented with different concentration of growth regulator.
