Abstract In order to develop techniques for efficient callus production and regeneration in Carica papaya (Var. Honey Dew), lamina, petiole, stem and root explants from in vitro plantlets were cultured in media supplemented with 2.0 mg/1 IBA and 0.5 mg/1 BAP. Use of in vitro-grown plantlets as an explant source helped to avoid contamination common in papaya tissue culture. Callusing was maximum in root explants cultured in a modified MS (half-strength) medium. Shoot reganeration was maxium in root-derived callus grown in full-strength modified MS medium supplemented with 0.5 mg/1 IBA and 1 to 2 mg/1 kinetin. A histological study indicated that shoot buds originated from peripheral cell layers of the callus. Each shoot regenerated from callus was subcultured using a multiplication medium. Root formation was induced in all shoots treated in half-strength of modified MS medium containing 2 mg/1 IBA and rooted shoots were transferred successfully to the field.
