‘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.
