Abstract In vitro methods for plant multiplication of a sterile interspecific hybrid between Brassica fruticulosa and B. campestris through either micropropagation or callus regeneration is described. Shoot-tip, single-node and leaf explants, obtained from in vitro-grown hybrids, regenerated on media containing NAA and BA. In vitro application of colchicine induced chromosome doubling in in vitro-regenerated shoots resulting in the production of fertile amphidiploids. Comparative studies on regeneration potential of the hybrid and its parents were also carried out using callus from leaf explants. The explants of B. fruticulosa and the hybrid were capable of shoot and root formation while those of B. campestris failed to form shoots but produced profuse roots. The results demonstrate the efficacy of an in vitro method in producing a large number of hybrid plants and fertile amphidiploids from incompatible crosses that yield very few hybrid seeds/seedlings.
