‘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(

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,

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 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’.
