Brassica oleracea varieties (red cabbage, broccoli, Savoy cabbage, and cauliflower) were tested for their ability to regenerate shoots in vitro. Cotyledon, hypocotyl and root explants of 7-day old seedlings were incubated on Murashige and Skoog (MS) medium supplemented with 1 mg/l 6-benzyladenine (BA) or 6-furfurylaminopurine (KIM) in combination with 0, 0.1, and 0.2 mg/l indole-3-butyril acid (IBA). Hypocotyls showed the best explants in almost all varieties tested with a minimum regeneration potential of 75% and producing 3.5-7.4 shoots per explant. The BA-supplemented media were optimal for both shoot regeneration and multiplication. Shoots rooted maximally (100%) on plant growth regulator-free MS medium containing 2% or 4% sucrose. Increased sucrose content improved plant acclimation in the greenhouse.
