Abstract	Dongfang no. 6, an intraspecific hybrid of kelp (Saccharina japonica) which was high in yield and had a high stress tolerance and was suitable for processing, was bred by crossing scientifically selected parental gametophyte clones. The sporophyte of the hybrid was raised by crossing a female gametophyte clone isolated from a Korean ecotype of S. japonica (Korean kelp) with a male gametophyte clone isolated from Lianza no. 1, a variety of S. japonica bred through continuous selection. The culture performance, stress tolerance, and suitability for processing of the hybrid and two commercial controls were compared for a period lasting 5 years (2009–2013). It was found that the hybrid was fast in growth, tolerant to high seawater temperature, resistant to strong solar irradiation, late in maturing time, and high in processed product yield. The percentage of salting processed product of the hybrid was 17.5 and 15.4 % higher than those of control 1 and 2, respectively. The yield of salting processed product of the hybrid increased by 24.2 and 38.8 % over control 1 and 2, respectively. The yield of air drying processed product of the hybrid increased by 109.4 and 88.1 % over control 1 and 2, respectively. The breeding of Dongfang no. 6 demonstrated that crossing gametophyte clones in combination with selecting desirable hybrids are highly effective for breeding kelp hybrids with high-culture performance and suitability for processing.
