영문 초록

The biodiversity research of barley, a functional food, is proceeding to conserve germplasms and develop new cultivar of barley to improve its functional effects. In this study, with 25,104 barley germplasms in the National Agrobiodiversity Center, South Korea, the biodiversity index of species was much lower (1.17) than the origins (24.73) because of the presence of a biased species, Hordeum vulgare subsp. vulgare, but the species and origin of germplasms were significantly different with regard to genetic traits. In the clustering analysis based on genetic traits, we found that 97% barley germplasms could mostly be distributed between 1~7 clusters out of a total of 15 clusters; ‘normal and uzu type’, ‘lodging’, and ‘loose smut’ were commonly represented in the 1~7 clusters and some clusters showed specific differences in five genetic traits including ‘growth habit’. In correlation of each genetic trait, the infection of ‘barley yellow mosaic virus’ was highly correlated to ‘number of grains per spike’. ‘1000 grain weight’ was weakly correlated with seven genetic traits including ‘number of grains per spike’. Our analysis for barley’s biodiversity can provide a useful guide to the species’ phenotypes that need to be collected to conserve biodiversity and to breed new barley varieties.
