Twelve oriental lily cultivars were hybridized in 32combinations using a modified cut-style pollination method. Rate of formation and number of seeds in pods varied from 0 to 100% and 11 to 245 respectively according to cross combinations. The seeds, treated in 0.5% NaOCl for 3 hours, germinated mostly within 4 weeks in vitro on 1/2 MS medium supplemented with 1% sucrose and 0.3% Gelite. The seedlings were grown in greenhouse to make flowering bulds and, from the fourth year, progenies of 7 crossing combinations began to bloom. Most progenies showed medium floral characteristics of parents. Among the progenies of selfed 'Le Reve', a double flowering individual was found. A hybrid of 'Marco Polo' x 'Muscadet' showed an unusual four petal flowers. And various aesthetically valuable progenies were found among the hybrids of the Oriental cultivars. These hybrids might be useful to select new cultivars following further tests for their characters and performance in cultural conditions.
