An experimental cultivation of Undaria pinnatifida was carried out in Naruto Strait, Tokushima Prefecture, by crossing male/female gametophytes derived from one zoospore which was obtained from two cultivar lineages (Y and H) from the Naruto area. Four experimental cultivation areas were set, namely the hybrid stock (Y male* H female, Y female* H male) and the true bred (Y male* Y female, H male* H female) gained by the crossing. Morphological variations, daily growth, and color tone were investigated in the experimental cultivation. Based on the morphology of the frond, the hybrid stock inherited the characteristics of the female. The daily growth of the hybrid stock showed the half value of the true bred. This result indicates the potential for cultivar improvement of Undaria pinnatifida by crossing gametophytes derived from one zoospore.
