This study was carried out to clarify the interspecific crossing compatibility and the germinating characteristics of interspecific hybridized seeds in the genus of Lycorisy spp. Total forty interspecific crossing combinations were made, and interspecific crossing compatibility and germination percentage were examined. When self pollinated, seed formations of L. koreana, L. aurea, L. satuma "HIRYU", L. radiata var. pumila. L. sprengeri were over 90%, that of L. radiata was less than 3.3%, and that of L. squamigera was not made. In the interspecific crossing, most of seed formation rates were over 70%, except L. squamigera, L. radiata and L. incanata. Seeds could be germinated from four months after interspecific hybridization at 10±2℃. However, those seeds could be germinated from two months after interspecific crossing and those germination percentages were increased at 25±2℃.
