“Joongmo2012”, a winter wheat (Triticum aestivum L.) cultivar was developed by the National Institute of Crop Science, RDA. It was derived from the cross “Sinmichal/Keumkang” during 2006. “Joongmo2012” was evaluated as “Iksan357” in advance yield trial test in 2010. It was tested in the regional yield trial test between 2011 and 2013. Its heading date was May 2 in upland and May 1 in paddy filed conditions, and Maturing date was June 8 in upland and June 8 in paddy field, which were similar to Keumkang, respectively. It showed 628 in number of spikes per m2, 34 of grain number per spike, 47.6g of 1,000 grain weight, and 762g of test weight. “Joongmo2012” showed susceptible to Fusarium head blight (Scab) in test of specific character although “Keumkang” is susceptible to scab. “Joongmo2012” had lower flour yield (68.4%) than “Keumkang” (73.5%, respectively). “Joongmo2012” showed similar ash (0.40%), lower protein content (11.7%), SDSsedimentation volume (39.8ml) and gluten content (8.1%) than “Keumkang” (0.41%, 12.7%, 55.8ml and 9.2%, respectively). It showed higher lightness (92.70) in flour color than “Keumkang” (91.51, respectively). “Joongmo2012” exhibited lower hardness (3.19N), similar springiness and higher cohesiveness of cooked noodles (0.90 and 0.66) compared to “Keumkang” (4.21N, 0.90, and 0.62, respectively). The average grain yield in the regional yield trial was 5.48MT/ha in upland and 4.47 MT/ha in paddy field, which were higher 5% and similar than those of the check cultivar, Keumkang, respectively
