ABSTRACT

Barley is one of the main cereals for mixed-rice, and it has been introduced as waxy source from 1980s in Korea. Beta-glucan, protein and waxy are very important quality factors and health functional ingredient in barley, respectively. We developed the new barley variety which contained high β-glucan. New variety is about twice of the β-glucan content 11.4% compared to the previous varieties of 6.5%, and it has yellow grain, good palatability after cooking and quality of barley flour as well. In 2007, it was crossed with Glacier AC38 of high amylose content and Shikoku Hadaka 97 of high β-glucan content, from Japan’s germplasm. After F3 generation, we selected one pedigree with excellent agricultural traits such as heading, mature stage, and logging. The yield was also tested the adaptation for three years from 2013. It was showed a similarity to the others barley cultivars with a yield of 3.2 ton ha^-1 in the paddy field of Korea. Further, as a result of analysis of quality characteristics, the particle size of the powder was smaller than the naked barley, so it was expected to suitable for processing products. The new variety was named "Beta-One", means the best quality and high content of β-glucan.
