Abstract: | An attempt to induce shoot regeneration from leaf disc explants from Allium sativum L., A. porrum L., and A. schoenoprasum L. and the induction of shoot regeneration from single flower-bud receptacles in A. porrum is presented. While the regeneration rate from leaf disc explants was low, an efficient method for propagating A. porrum in vitro was obtained by cultivating single flower-bud receptacles. The shoot regeneration ability was strongly controlled by the genotype. Up to 294 shoots per leek plant could be harvested. Simultaneously the same plant could be used for seed production and bulbil formation in vivo. The efficiency of the in vitro multiplication method described allows the integration of this procedure into breeding programmes of A. porrum
