In order to obtain plantlet derived by anthers, the anthers of Lilium asiatic hybrid 'Gran Paradiso' were cultured on Murashige and Skoog's medium supplemented with various combinations of auxin and cytokinin. The most suitable pollen stage of anther culture for the callus induction was 3 days before anthesis at the early to late binucleate stage. Organogenic calli were induced on MS medium supplemented with 5.0 mg/L 2,4-D alone and the combination of 1.0 mg/L 2,4-D and 1.0 mg/L kinetin, however, the combination of NAA and BA was more effective than that of 2,4-D and kinetin on plant regeneration through organogenesis. Shoots were formed from the induced callus on the medium with 0.5 mg/L NAA and 1.0 mg/L BA after 180 days of culture. Multiple shoots with 3-4 leaves, roots, and bulblets were formed on the medium with the combination of 2.0 mg/L NAA and 2.0 mg/L BA after 250 days of culture. The chromosome from root tip of the regenerated plantlet showed the diploid (2n=2x=24). Diploid plants were transferred to the pots and all plants were flowered in two years.
