Present study was carried out to standardize a protocol for high efficiency in vitro plant regeneration system in Capsicum annuum L. cv. California Wonder using cotyledon explants. Various concentrations of 6- benzylaminopurine (BA), indole-3-acetic acid (IAA) and thidiazuron (TDZ) were used for shoot regeneration. Highest percentage of shoot regeneration (80.95%) was obtained on Murashige and Skoog (MS) medium supplemented with 6.0 mg/l BA and 0.3 mg/l IAA. Initiation of shoots was observed after about 20 days on this concentration of hormones. The regenerated shoots were in form of profuse rosettes which underwent fair elongation of 2-2.5 cm on transfer to MS medium supplemented with 2.25 mg/l BA and 2 mg/l gibberellic acid (GA3). In vitro induction of roots occurred after 10-12 days of transfer of shoots to root regeneration medium. Half- strength MS medium containing 0.25 mg/l IAA gave the highest percentage (50%) of in vitro root induction. Plantlets showed successful acclimatization on hardening. Standardization of an efficient in vitro regeneration protocol could be helpful in carrying out various genetic modifications in this economically important crop.
