‘Jungmo2503’ (Hordeum vulgare L.), a new ruminant-palatability forage barley cultivar, was developed by the breeding team at the Department of Rice and Winter Cereal Crop, National Institute of Crop Science, RDA in 2011. It was derived from the cross between ‘Dongsanpi81’ and ‘Kangbori’. Among the cross made in 1999, a promising line, SB992028-B-B-B-B-B-2, showed good characteristics in potential forage yield in the yield Trial tested at Iksan in 2007 to 2008 designated as Iksan 449. The line in the Regional Yield Trials (RYT) tested in eight locations around Korea for three years from 2009 to 2011, and was released as the name of ‘Jungmo2503’. It has the growth habit of group Ⅰ, erect plant type, green leaf and hood spike. Its average heading and maturing dates were on May 2, and May 29, respectively, with are similar to check cultivar ‘Yuyeon’. The cultivar had 102cm of culm length, 691 spikes per m2 and it showed better rate of leaf, winter hardiness, and resistance to BaYMV than those of the check cultivar. The average forage yield of ‘Jungmo2503’ was about 10.9 ton ha-1 in dry matter in paddy field. ‘Jungmo2503’ also showed 9.4% of crude protein content, 27.3% of ADF (Acid Detergent Fiber), 49.0% of NDF (Neutral Detergent Fiber), and 67.3% of TDN (Total Digestible Nutrients), including higher grade of silage quality for whole crop barley.

청보리 신품종 '유호'는 까락이 없어 가축 기호성이 높지만 수확 시 곡실의 탈립이 많아 수량 및 영양적 손실이 큰 기존 삼차망 품종 '유연'의 단점을 개선하기 위하여 1999년에 내탈립 삼차망인 수원339호를 모본으로 하고, 보리호위축병에 강하고 총체적성에 좋은 수원355호를 부본으로 교잡하여 계통육종법에 의하여 제반 특성이 우수한 'SB992047-B-B-B-6-2' 계통을 선발, 생산력검정시험과 지역적응시험을 거쳐 2008년에 육성되었다. 그 특성을
