‘Jungmo2501’ (Avena sativa L.), a winter oat for forage use, was developed by the breeding team at the National Institute of Crop Science, RDA in 2010. The following is the characteristics of ‘Jungmo2501’ that is characterized as light green leaf, yellow brown culm and whitish yellow grain. The heading date of ‘Jungmo2501’ was about 3 days earlier than that of check cultivar ‘Samhan’(May 7 and May 10, respectively). Its plant height was 11 cm longer than 103 cm of the check, and the leaf blade ratio of aerial parts was 26 % higher than the check (11.8% and 9.4%, respectively). The cold tolerance, resistance to lodging and wet injury of ‘Jungmo2501’ were similar to those of the check. The average forage dry matter yield of ‘Jungmo2501’ harvested at milk-ripe stage was 5% higher than the check (15.5 ton ha -1 and 14.7 ton ha -1 , respectively). ‘Jungmo2501’ was higher than the check in terms of protein content (6.6% and 5.9%, respectively), neutral detergent fiber (58.5% and 57.6%, respectively), and acid detergent fiber (34.5% and 32.1%, respectively), while total digestible nutrients was lower than the check (61.6% and 63.6%, respectively), and TDN yield was 0.37 ton ha -1 more than that of the check (9.71 ton ha -1 and 9.34 ton ha -1 , respectively). The silage grade of ‘Jungmo2501’ estimated by Flig score showed level Ⅱ, meaning good quality. Fall sowing cropping of ‘Jungmo2501’ is recommended only for areas where average daily minimum mean temperatures in January are higher than －6°C.

Improvement of winter hardiness, lodging resistance and good quality have been recently received more attention by covered barley(Hordeum vulgare L.) breeders than ever in Korea. ‘Hyeyang’, a new covered barley cultivar with early maturing and high yield was developed by the National Institute of Crop Science, RDA in 2010. It was derived from the cross between‘Milyang87’and‘Wolsung8120’with good quality. The initial cross was done in 1999 and the selected line, ‘Iksan432’ (YB4494-B-B-21-2), showed high yield and good quality characteristics under yield trial test from 2008 to 2010. The following is the characteristics of‘Hyeyang’that is characterized as the vernalization of I, green leaf, compact spike and long rough awns. The heading date of‘Hyeyang’were similar to‘Olbori’. The culm length was 82 cm which was 6 cm shorter than‘Olbori’. It showed the spike length of 4.3 cm, 798 spikes / m², 56 grains / spike and 26.7 g for 1,000 grains weight. It showed similar winter hardiness and stronger resistance to barley yellow mosaic virus (BaYMV) compare to‘Olbori’. It showed higher diastatic power 235DP than that of check cultivar, ‘Olbori’. Average yield of ‘Hyeyang’ was 4.44 MT/ha in the regional yield trials carried out in four location at double cropping system in Korea from 2008 to 2010, which was 8 percent higher than ‘Olbori’. ‘Hyeyang’would be suitable for the area above –8°C of daily minimum temperature in January in Korean peninsula.

Molecular markers related to flour qualities of long spike wheat lines were evaluated. Ash, wet gluten and protein content of long spike wheat lines were higher than Keumkang(Korean wheat cv.) but SDS-sedimentation volume(SDSF) was lower. Particle size and lightness of flour of long spike wheat lines showed similar to Keumkang. The high positively correlation was presented between protein content and SDSF, wet gluten and particle size, respectively. However, negatively correlation was between protein content and lightness. Through the analysis of molecular markers, we identified the genotypes of four genes, Glu-A3c, Wx-A1a, Wx-B1a and Wx-D1a. These genes had same genotypes with Keumkang. Six genes, Glu-A1c, Glu-B1c, Glu-D1a, Glu-B3g, Pina-D1and Pinb-D1b, were presented in most of the lines. Two genes, Glu-A1 and Glu-B1b, were related to higher protein contents and wet gluten. The lines containing three genotypes, Glu-D1d, Glu-B3h and Pinb-D1b, had higher ash, protein contents, SDSF and wet gluten, and lightness was darker. Through the results, we expect that long spike type wheat lines are necessary to breed wheat having high yield productivity.

A novel auricleless bariey (Hordeum vulgare L.) cultivar ‘Jomi’ was developed which shows high biomass yield, good quality and high ruminant-palatability at National Institute of Crop Science, RDA in 2010. This cultivar was derived from a cross of the ‘Suwon337’ and ‘Suwon355’ in 1999 and a promising line showing both high yield and lodging resistance through the preliminary and advanced yield trials at Iksan in 2006-2007, was designated as the ‘Iksan 438’. ‘Iksan438’ was conducted to regional yield trials (RYT) in seven locations around Korea for three years from 2008 to 2010, and was released as the name of ‘Jomi’. It has erect plant type, growth habit of Ⅰand green and auricleless leaf . Its heading date was April 23 and maturing date was May 25 in paddy field, 3 days and 1 day earlier than ‘Youngyang’, respectively. The cultivar showed 90cm of culm length, 846 spikes per m2, high rate of leaf blades, resistance to BaYMV and better winter hardiness than that of ‘Youngyang’, The average forage yield of ‘Jomi’ was about 10.3 ton ha^-1 in dry matter (28 ton ha^-1 in fresh matter) in paddy field with 8.3% of crude protein content, 26.2% of ADF (Acid Detergent Fiber), 48.3% of NDF (Neutral Detergent Fiber), 68.2% of TDN (Total Digestible Nutrients) and grade Ⅱ of silage quality. This cultivar would be suitable for the area above the daily minimum temperature of -8°Cin January in Korean peninsula.

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.

A soybean cultivar for sprout, ‘Joyang 1’ was developed at the National Institute of Crop Science (NICS) in 2010. ‘Joyang 1’ (Iksan67) was released by pedigree selection from the cross between high yielding ‘Pungsannamulkong’ and ‘Suwon187’ tolerant to lodging and disease. It has purple flower, lanceolate leaf, grey pubescence and small yellow seed. Weight of hundred seed is 11.6gram. Maturing date of ‘Joyang 1’ is ten days earlier than check cultivar, ‘Pungsannamulkong’. ‘Joyang 1’ is resistant to bacterial pustule and shattering. It have similar tolerance to root rot and seed spot to check cultivar. It shows high germination ratio, less abnormal germination and hard seed. Sprout yield also 11 percent higher than check cultivar. The average seed yield of ‘Joyang 1’ was 3.03 ton per hectare in the regional yield trials (RYT) carried out for three years from 2008 to 2010 which was 3 percent higher than the check cultivar. The number of breeder’s right is ‘4900’.
