“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.

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

End-use properties of 26 Korean wheat cultivars(KWC) were evaluated to assess consumer satisfaction with 6 imported wheat and 5 commercial wheat flours. In end-use quality testing of cooked noodles, Absorption of noodle dough sheet of ASW(Australian standard white) was similar to Anbaek, Eunpa, Gobun, Hanbaek, Jeokjoong, Jonong, Namhae, and Sukang. In lightness of prepared noodle dough sheet, Lightness value(L*) of KWC was lower than those of commercial flour for making white salted noodle(Com1), commercial flour for making for yellow alkaline noodle(Com2), and commercial flour for multi-purpose(Com4). Lightness value(L*) showed significantly negative correlations with particle size of flour, ash, damaged starch, and protein content. Hardness of cooked noodles positively correlated with protein content. In end-use quality of bread, Bread volume of commercial flour for making bread(Com3) was similar to Alchan, Jokyung, Keumkang, and Namhae but firmness was low. Bread volume showed better relationships with higher SDS-sedimentation volume, longer mixing time of mixograph, higher height of dough during development. Diameter of cookie showed significantly negative correlations with particle size of flour, damaged starch, and protein content. Also, Top gain score became higher as the increase diameter of cookie. In end-use quality testing of cooked cookie, Cookie diameter of Com5 was similar to that of Dahong, Geuru, Olgeuru, Tapdong, and Uri but top grain was low.

Flour physicochemical properties of 26 Korean wheat cultivars, 7 imported wheat and 5 commercial wheat flours were evaluated to determine making for yellow alkaline noodles (YAN) in this study. In physical characteristics of YAN, ash and damaged starch content was 0.42% and 3.79%. Flour color of YAN was 92.17 in L*, -1.45 in a* and 9.77 in b*. Protein content, SDS-sedimentation based on a constant flour weight (SDSSF), on a constant protein weight (SDSSP) and dry gluten content was 11.97%, 59.00 mL, 48.00 mL and 8.20%. Water absorption, mixing time and tolerance of mixograph was 61.50%, 3.75 min and 24.00 mm. In starch characteristics, amylose and total starch was 23.72% and 76.10. L* value of flour decreased when ash, damaged starch, protein content of flour increased. Protein content of wheat flour was positively correlated with SDSSP, dry gluten and mixograph water absorption. SDSSF showed positively correlated with SDSSP, mixograph mixing time and mixing tolerance (r = 0.641, P < 0.001, r = 0.464, P < 0.05 and r = 0.618, P < 0.001, respectively) and SDSSP positively correlated with dry gluten, mixograph water absorption, mixing time and mixing tolerance (r = 0.550, P < 0.05, r = 0.520, P < 0.01, r = 0.396, P < 0.05 and r = 0.552, P < 0.01, respectively).
