“Joongmo2008”, a winter wheat (Triticum aestivum L.) cultivar was developed by the National Institute of Crop Science, RDA. It is an awned, semi-dwarf and hard winter wheat. The heading and maturing date of “Joongmo2008” were similar to “Keumkang”. Culm and spike length of “Joongmo2008” were 87 cm and 8.6 cm. It had similar test weight (800g/L) and higher 1,000-grain weight (46.7g) than “Keumkang”. It showed resistance to winter hardiness and moderate to pre-harvest sprouting, which lower rate of pre-harvest sprouting (9.8%) than “Keumkang”. “Joongmo2008” had higher flour yield (73.5%) and higher ash content (0.49%) than “Keumkang”. It showed similar lightness (90.01) of flour color than “Keumkang”. It showed higher protein content (16.4%), gluten content (13.4%), SDS-sedimentation volume(59㎖) and mixing time of mixograph than “Keumkang”. “Joongmo2008” had lower amylose contetn (24.5%) and higher viscosity (153BU) than “Keumkang”. It showed same compositions in HMW-GS compositions(5+10) and Puroindolines composition compared to “Keumkang”. “Joongmo2008” showed lower firmness (0.74N) of and higher bread volume of baked pan-bread to “Keumkang”. Average yield of “Joongmo2008” in the regional adaptation yield trial was 4.54 ton/ha in upland and 3.67 ton/ha in paddy field. “Joongmo2008” would be suitable for the area above -10℃ of daily minimum temperature in January in Korean peninsula.
