‘Jungmo2502’ awnless barley line (Hordeum vulgare L.) developed at National Institute of Crop Science, RDA in 2011. The Jungmo2502 derived from three-way cross between Millyang100 and F1 (Samheung/Suwon300) in 2000. Subsequent generation were handled by the bulk method in a pedigree selection program. A promising line showed high yield as well as lodging resistance in the yield trial tested at Iksan in 2007 to 2008, designated as Iksan 448. The line in the regional yield trials(RYT) tested in seven locations around Korea for three years from 2009 to 2011. The Jungmo2502 is carrying the growth habit of Ⅳ, green leaf and stem similar to the check cultivar ′Youngyang′. Its heading date was May 3, and maturing time was May 30 in paddy field, which was 3 days later respectively than check cultivar. It was 98 cm of culm length, 607 spikes per m2 and showed more rate of leaf blade, winter hardiness, and resistance to BaYMV than the check cultivar. Average dry matter yield was similar with the check cultivar in paddy field (about 11 ton ha-1). It also showed good qualities as 8.7% of crude protein, 21.9% of ADF (acid detergent fiber), 40.7% of NDF (neutral detergent fiber), and 71.6% of TDN (total digestible nutrients), including high grade of silage for whole crop barley.
