‘Joongmo2003’, a winter wheat (Triticum aestivum L.) cultivar was developed by the National Institute of Crop Science, RDA. It was derived from the cross ‘SW86054/Keumkang’ during 1997. ‘Joongmo2003’ was evaluated as ‘Iksan318’ in advance yield trial test in 2006. It was tested in the regional yield trial test between 2007 and 2009. Its heading date was April 24 in upland and April 21 in paddy filed conditions, which was two days earlier than those of the check cultivar ‘Keumkang’, respectively, and maturity date was June 4 in upland and June 2 in paddy field, one or two days earlier than those of ‘Keumkang’, respectively. ‘Joongmo2003’ showed resistance to winter hardiness and pre-harvest sprouting, which lower withering rate on the low ridge (0.3%) and rate of pre-harvest sprouting (18.5%) than ‘Keumkang’ (9.2 and 25.8%, respectively). ‘Joongmo2003’ showed similar protein content (13.2%), lower SDS-sedimentation volume (54.0 ml) and higher gluten content (11.7%) than ‘Keumkang’ (13.1%, 57.8ml and 10.8%, respectively). It showed higher lightness (89.85) of flour and noodle dough sheet than ‘Keumkang’ (89.81 and 80.28, respectively). ‘Joongmo2003’ exhibited similar hardiness (3.84N), springiness and cohesiveness of cooked noodles (0.92 and 0.63) compared to ‘Keumkang’ (4.54N, 0.93, and 0.63, respectively). The average grain yield in the regional yield trial was 555 kg/10a in upland and 485 kg/10a in paddy field, which were 4% and 7% lower than those of the check cultivar, ‘Keumkang’, respectively.
‘Sooan’, a winter wheat (Triticum aestivum L.) cultivar was developed by the National Institute of Crop Science, RDA. It was derived from the cross ‘Keumkang/Eunpa//Keumkang’ during 1997. ‘Sooan’ was released from the line named as ‘Iksan319’ in 2009 after yield trials test in conducted for three years from 2007. It was tested in the regional yield trial between 2007 and 2009. ‘Sooan’ is an awned, semi-dwarf and hard winter wheat, similar to ‘Keumkang’ (check cultivar). The heading and maturing date of ‘Sooan’ were similar to ‘Keumkang’. ‘Sooan’ had similar test weight (817 g/L) and lower 1,000-grain weigh (43.7 g) than ‘Keumkang’ (817 g/L and 46.2 g, respectively). ‘Sooan’ showed resistance to winter hardiness and pre-harvest sprouting, which lower withering rate on the low ridge (0.2%) and rate of pre-harvest sprouting (0.2%) than ‘Keumkang’ (9.2 and 25.8%, respectively). ‘Sooan’ showed lower protein content (12.7%), SDS-sedimentation volume (42.0 ml) and gluten content (10.5%) than ‘Keumkang’ (13.1%, 57.8ml and 10.8%, respectively). It showed higher lightness (90.08) and lower redness (-1.11) and yellowness (8.80) in flour color than ‘Keumkang’ (89.81, -1.15 and 9.46, respectively). ‘Sooan’ showed higher lightness (81.34) of noodle dough sheet than ‘Keumkang’ (80.28). ‘Sooan’ exhibited lower hardness (3.84N) and similar springiness and cohesiveness of cooked noodles (0.91 and 0.65) compared to ‘Keumkang’ (4.54N, 0.93, and 0.63, respectively). Average yield of ‘Sooan’ in the regional adaptation yield trial test was 5.94 kg/10a in upland and 5.63 kg/10a in paddy field, which was 3% and 8% higher than those of ‘Keumkang’ (579 kg/10a and 520 kg/10a, respectively).
