‘Goso’, a winter wheat (Triticum aestivum L.) cultivar was developed by the National Institute of Crop Science, RDA
for end-use diversity. It was derived from the cross ‘Gobun/Ol” during 1998. ‘Goso’ was released from the line named as ‘Iksan325’ in 2010 after yield trials test in conducted for three years from 2008. ‘Goso’ is an awned, semi-dwarf, red grain and soft winter wheat. The heading and maturity date of ‘Goso’ were similar to ‘Keumkang’. ‘Goso’ had similar test weight (799g/L) and lower 1,000-grain weight (42.5 g) than ‘Keumkang’ (804 g/L and 46.7 g, respectively). ‘Goso’ showed resistance to winter hardiness and pre-harvest sprouting, which withering rate on the low ridge (4.4%) and lower rate of pre-harvest sprouting(4.0%) than ‘Keumkang’ (1.6% and 29.8%, respectively). ‘Goso’ showed lower flour yield (63.7%), protein content (9.8%), SDS-sedimentation volume (30.0 ml) and gluten content (7.2%) than ‘Keumkang’ (73.6%, 12.6%, 50.0 ㎖ and 10.8%, respectively). It showed larger diameter (88 mm) and top-grade (5) of cookie than ‘Keumkang’ (79 mm and 2, respectively).
HMW-GS compositions of ‘Goso’ were 2* in Glu-A1, 7+8 in Glu-B1 and 2.2+12 in Glu-D1, respectively. GBSS composition of ‘Goso’ was same with ‘Keumkang’ and expressed wild type. Pinb-D1 was wild type that was different in ‘Keumkang’.
Average yield of ‘Goso’ in the regional adaptation yield trial test was 657 kg/10a in upland and 561 kg/10a in paddy field, which was 21% and 7% higher than those of ‘Keumkang’ (545 kg/10a and 524 kg/10a, respectively).
