Interspecific crossing in the Laminariaceae has been carried out for long time. Many investigators considered that interspecific hybridization takes place among many species in Laminaria and that crosses between three species in Undaria are also complete interfertility. In this paper, hybridizations between Eisenia bicyclis, Ecklonia cava, Ecklonia stolonifera and Ecklonia kurome were investigated in laboratory and field cultures. Intergeneric and interspecific crosses were possible between any pair of the four species in Eisenia and Ecklonia. Among the four species, Ecklonia cava has smooth leaves, but other three species have densely rugose leaves. After 3 months culture in the field, the hybrids between Ecklonia cava ♀ and Eisenia bicyclis ♂ showed intermediate morphological aspects of their parents in occurrence of rugae on leaves. The hybrids between Ecklonia cava♀and Ecklonia kurome ♂ and between Ecklonia cava ♀ and Ecklonia stolonifera ♂ had similar results.
