Abstract:
Native Japanese Lilium species, which have been often used in the breeding of Oriental hybrid lilies, are difficult to cultivate. The degree of difficulty of raising seedlings (from the most difficult to easiest) of the species is as follows:

• Lilium noblissimum (the Japanese name is tamoto-yuri) — the most difficult species;
• Lilium japonicum (sasa-yuri) and L. auratum (yama-yuri);
• Lilium alexandrae (uke-yuri) and L. rubellum (otome-yuri);
• Lilium speciosum (kanoko-yuri) — relatively easy.

All of the species mentioned above show good germination, but they grow very slowly. During the first year, they produce only small bulbs (ca. 2- to 5-mm. diameter). They are also susceptible to pests and diseases. At the flowering stage (5 to 6 years after sowing) almost all plants lose their vigor because of infection by viruses and infestation by bulb mites. Therefore, we tried to raise seedlings of several Japanese lilies in vitro in order to conserve them for garden use and to prepare
