‘Jungmo2506’ (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 2013. It was derived from the cross between ‘Sunwoo’ and ‘Milyang 34’. Among the cross made in 2002, a promising line, SB02T2020-B-BB- 64, showed good characteristics in potential forage yield in the yield trial tested at Iksan in 2009 to 2010 designated as Iksan 463. The line in the Regional Yield Trials(RYT) tested in eight locations around Korea for three years from 2011 to 2013, and was released as the name of ‘Jungmo2506’. It has the growth habit of group Ⅳ, erect plant type, green leaf and short awn spike. Its average heading and maturing dates were on May 3, and June 2, respectively, with similar to check cultivar ‘Youngyang’. The cultivar had 99cm of culm length, 692 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 ‘Jungmo2506’ was about 11.8 ton ha-1 in dry matter in paddy field. ‘Jungmo2506’ also showed 6.6% of crude protein content, 27.4% of ADF (Acid Detergent Fiber), 49.2% of NDF (Neutral Detergent Fiber), and 67.2% of TDN (Total Digestible Nutrients), including higher grade of silage quality for whole crop barley.
