Experiments were carried out to examine the rates of pod formation and asymbiotic seed germination in cross-and self-pollinated Cymbidium kanran natives of Cheju. The average pod formation rate of Cymbidium kanran was 75.0% in the self-pollinated plants and 66.7% in the cross-pollinated. The average fertility rate of the seeds from self-pollinated flowers was 50.0% and 53.3% from the cross-pollinated ones. The seeds from cross-pollinated flowers took 106 (59∼174) days and those from the self-pollinated took 164 (68∼329) days for germination. The rhizome formation from the asymbiotically-germinated seeds required 12 to 32 months depending upon the medium sources. Murashige and Skoog liguid medium was found the most effective for rhizome formation. Rhizome formation up to 0.5 ㎝ in length required about 12 months and the rate was about 40%.
