Barley breeding program of RDA (Rural Development Administration) has been develop to new hulled barley variety that has been used for malt and beer material. Through this program, we developed new two-rowed covered barley, Imaeg, with disease resistant, lodging tolerant and good malt quality for beer and Korean traditional drink 'Sikhye' in 2013. Imaeg showed resistant to Barley yellow mosaic virus (BaYMV), lodging tolerant and early maturing. The regional yield trials were conducted for Imaeg as a breeding line 'ksan166' during three years at four different regions. And then it was registered to Plant protection right, No. 5681 in 2015 after field experiment by KSVS (Korea Seed and Variety Service). Imaeg has I of vernalization and shorter stem length as 77cm than 7cm to control variety Hopum. Yield potential of Imaeg about 4.8ton/ha that higher about 3% in paddy field condition than control, however, it has no significant difference. In quality examination for beer usage, Imaeg has higher 1,000 grain weight (45.6g) and higher assortment ratio (93.6%) than those of Hopum as 42.6g and 90.4% respectively. In malt quality, Imaeg showed higher soluble protein, Kolbach index and diastatic power than those of Hopum significantly. In addition, Imaeg has better 'Sikhye' malt quality significantly in lightness of grain (58.4 L value) and growth rate (216.8%) than those of Hopum as 54.3 (L value) and 177.5% respectively. Imaeg would be suitable for cultivation at the area above -4Celsius of daily minimum temperature in January in Korean peninsula.
