Studies were conducted with sweet orange (Citrus sinensis L. Osbeck.) cv. Mosambi and Jaffa using epicotyl segments from in vitro grown nucellar seedlings. BAP (up to 1 mg/litre) was found optimum. However in Jaffa, maximum shoot proliferation was observed with BAP (2.0 mg/litre). Root development was maximum at the concentration of NAA (0.5 mg/litre) + IBA (0.5–1.0 mg/litre). However, root development was also better at NAA (1.0 mg/litre) alone. The complete plantlets were obtained with a survival rate of 66–67%.
