There are many articles on the research on the isolation and culture of somatic cell of Porphyra yezoensis. However, there are few reports about the production of young plants and the culture of the sea. This article mainly reports the authors’ summary of the research conducted on nursery and culture of the body of Porphyrayezoensis from 1988 to 1993. The work is summarized as two main aspects. One is to improve the technology of breeding, reduce the cost of nursery and simplify the nursery process to expand the area of breeding.
