选择性状差异较大的日本长海带（Laminaria longissima）和当地早厚成品系一号（L.japonica）为母父本，通过杂交获得F1，F1经连续五年的自交选育获得”901”海带新品种。该品种具有生长速度快、耐高温的经济性状和色泽浓褐、个体宽大、纵沟较明显、基部终身楔形，近基部1m处呈微弧形的形态性状。经两年生产实践证明：”901”性状遗传较稳定，产量高，质量优。
Laminaria longissima and L.japonica were selected as the parents of parents with large differences in their traits. F1 and F1 were obtained by cross breeding for 901 after five years of selfing, Kelp new varieties. The varieties with fast growth, high temperature resistant economic properties and rich color brown, individual generous, more obvious longitudinal groove, the base of the wedge-shaped, near the base 1m at the micro-arc-shaped morphological traits. After two years of production practice has proved that: “901” traits inheritance more stable, high yield, excellent quality.
