Leaves of wild apple (Malus domestica Borkh) were excised from in vitro grown shoots transversely cut into halves and plated onto petri dishes containing regeneration media. Cultures were kept in the dark for three weeks before adventitious shoots were observed. Callus from leaf explants produced adventitious shoots after 3 months of in vitro culture. Callus were cultured on Nitsch and Nitsch medium supplemented with a range of BA (0.0–2.0 μm) and NAA (0.0–10 μm). BA at 10 μm combined with NAA (0.5 μm) proved most effective for stimulating shoot proliferation of cultured apple. Plantlets from tissue culture were easily transferred to the greenhouse environment.
