‘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 (799 g/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).

A new naked oat (Avena sativa L.) cultivar ‘Suyang’ was developed by National Institute of Crop Science, RDA in 2010. It was derived from the cross between ‘Sikyonggwiri’ and ‘Gwiri23’. Subsequent generations were handled in a bulk method and pedigree selection program, and ‘SO96025-B-303-44-2-4’ was selected for agronomic appearance in 2002. The line showed both high yield and good husking rate of seed in the Yield Trial tested at Suwon in 2003 to 2004, being designated as ‘Gwiri56’. The ‘Gwiri56’ was subsequently evaluated for winter hardiness, earliness, and yield in four locations, Gimje, Iksan, Jeongeup and Jinju from 2005 to 2010 and was released as the name of ‘Suyang’. ‘Suyang’ had 11 days earlier heading date and 6 days earlier maturing time than the check cultivar ‘Seonyang’ in field condition. The ‘Suyang’ had 23.7 cm of spike length, 568 spikes per m², 73 grains per spike, 29.2 g of 1,000-grain weight, and 646 g of test weight. ‘Suyang’ showed better winter hardiness than that of the check cultivar ‘Seonyang’, and similar seed quality to the check cultivar in respect to crude protein (11.3%) and β-glucan content (4.7%). However, it showed higher husking rate than that of check cultivar. The grain yield of ‘Suyang’ in the regional yield trial for 4 years was averaged 4.35 MT ha^-1, which was 29% higher than that of the check cultivar ‘Seonyang’. ‘Suyang’ is recommended for fall sowing cropping only in the south area where daily minimum mean temperatures are averaged higher than -4°C in January.
