We developed new two-rowed covered barley ‘Gwangmaeg’ superior to ‘Hopum’ that has been widely cultivated in Korea for using beer-materials. ‘Gwanngmaeg’ was related from the line named as ‘Iksan149’ in 2010 after yield trials test in conducted for three years from 2008. And then it was registered to ‘Plant protection right, No. 5847’ in 2016 after field experiment by KSVS(Korea Seed & Variety Service). ‘Gwangmaeg’ has distinct characteristics in winter type (IV) and mid-tall culm length which makes reduce damage by off-season heading and lodging comparing to those of ‘Hopum’. ‘Gwangmaeg’ have characteristics of cold tolerance and disease resistance to BaYMV(Barley yellow mosaic virus) and Net blotch(Pyrenophora teres). Yield of ‘Gwangmaeg’ was about 611kg/10a and 524kg/10a in upland and paddy field condition, respectively, which higher 2-4% than ‘Hopum’, however, it has no significant difference. In quality examination for beer usage, ‘Gwangmaeg’ has lager grain and higher assortment ratio than those of ‘Hopum’. In malt quality, ‘Gwangmaeg’ showed higher and better quality in malt extract rate and diastatic power than those of ‘Hopum’. ‘Gwangmaeg’ would be suitable for the area above –4℃ of daily minimum temperature in January in Korean peninsula.
