The present invention relates to Porphyra yezoensis seopoong [deposit number: KCTC 12219BP] having a laver leaf with a saw-toothed edge and wave resistance. The new variety of Porphyra yezoensis seopoong in the present invention is cultured by transplanting free filaments into a shell, whereupon it grew faster than the general Porphyra yezoensis and each sporangium was matured well and seedling collection was good due to an active abjection of conchospore in case of collecting the seedling from the land and the attachment rate per unit area was higher than natural seedling collection in a busy season and the production per unit area is high in a laver farm, and it has an excellent wave resistance, thereby being able to contribute to an increase of the income of fishermen in the area of yellow sea having a large tidal range.본 발명은 김 엽체 가장자리에 거치를 가지고 내파성이 뛰어난 방사무늬 김 서풍(Porphyrayezoensis seopoong)[기탁번호: KCTC 12219BP]에 관한 것으로, 본 발명의 신품종 방사무늬 김 서풍은 유리사상체를 패각에 이식하여 배양한 결과, 일반 방사무늬김보다 빠른 생장을 나타내었고, 각 포자낭이 잘 성숙되었으며, 육상채묘에서 각포자 방출이 활발하여 채묘가 양호하였고, 분망시기에 단위면적당 부착율이 자연채묘보다 높았으며, 김 양식장에서 단위면적당 생산량이 높고, 내파성이 뛰어나 조수간만이 심한 서해안 지역의 어민의 소득증대에 기여할 수 있다.
