ABSTRACT The use of seaweeds as human food in eastern Asian countries has a long history, stretching back over a thousand years. However, it was not until the late 1940s that cultivation of seaweeds in near-shore coastal areas began. Due to their location, the Korean peninsula, the Japanese islands and the Chinese coasts share a similar seaweed flora in their coastal waters, and it is not surprising that seaweed species chosen for cultivation, methods of farming and post-harvest processing in these countries have a lot in common. In 2016, the total seaweed production in these three countries reached 16,218,406 t, approximately 53.8% of global seaweed production (FAO). In the course of seaweed farming development in eastern Asia, the development and use of seaweed cultivars have contributed significantly to the seaweed farming industry in terms of improving both the biomass yield and the quality of the food products produced. In this article, the recent development of cultivar-related research and applications practised in Korea, Japan and China are reviewed with particular reference to the key commercial species: Saccharina japonica, Pyropia spp., Undaria spp., Cladosiphon okamurarus, and Nemacystus decipiens. In the past 21 years, 47 certified seaweed cultivars have been used in commercial cultivation in these countries. While much of the development effort has focused on increasing yields, a current emphasis in cultivar breeding programs is to increase the quality of farmed seaweed products. More recently, molecular analyses have been integrated into these programs and have become indispensable tools in the breeding process.

• Opportunities, challenges and future directions of open-water seaweed aquaculture in the United States (2019, methodology): “For example, He & Yarish (2006) cultured the conchocelis of Py. yezoensis (misidentified as Py. leucosticta in their paper at the time) not only by using shells (as per the traditional cultivation technology in Asia) but also in a novel, ‘free-living’ suspension in 13-litre Pyrex jar culture vessels”
• Seaweed cultivation and utilization of Korea (2020, background): “japonica increased by 671% between 2001 to 2015, and the cultivation area is now 9,147 ha (Hwang et al. 2019).”
• The potential of seaweed cultivation to achieve carbon neutrality and mitigate deoxygenation and eutrophication (2021, background): “…cultivated in summer are needed to be identified or obtained through genetic engineering in future studies because the extension of the cultivation period in summer could significantly enhance the annual productivity of seaweeds and thus their capacities for C, N and P removal (Hwang et al 2019).”
• Phyconomy: the extensive cultivation of seaweeds, their sustainability and economic value, with particular reference to important lessons to be learned and transferred from the practice of eucheumatoid farming (2019, background): “Inasmuch as the above issues are lessons for carrageenophyte production, the same phyconomic principles apply to largescale cultivation of other common seaweed crops e.g. Porphyra/Pyropia, Laminaria/Saccharina and Undaria (see Hwang et al. 2019).”
