Abstract
Hypocotyl protoplasts from oil rape, Brassica napus L. cv. Isuzu were cultured in the dark at 25°C in a modified Nitsch and Nitsch medium containing 13% sucrose, 5 g/l Ficoll, 0.5 mg/l BAP, 1 mg/l NAA and 0.5 mg/l 2–4 D. Protoplasts floated on the surface of the medium and developed into microcolonies 0.5 mm in diameter in 4–6 weeks. The microcolonies also remained on the surface of the medium. Transfer to MS medium supplemented with 200 mg/l casein hydrolysate, 5mg/l BAP, 0.5 mg/l NAA and solidified with 0.6% agarose induced shoot regeneration in 3–4 weeks.Keywords
