초록
A novel auricleless bariey (Hordeum vulgare L.) cultivar ‘Jomi’ was developed which shows high biomass yield, goodquality and high ruminant-palatability at National Institute of Crop Science, RDA in 2010. This cultivar was derived from a crossof the ‘Suwon337’ and ‘Suwon355’ in 1999 and a promising line showing both high yield and lodging resistance through thepreliminary and advanced yield trials at Iksan in 2006-2007, was designated as the ‘Iksan 438’. ‘Iksan438’ was conducted toregional yield trials (RYT) in seven locations around Korea for three years from 2008 to 2010, and was released as the nameof ‘Jomi’. It has erect plant type, growth habit of Ⅰand green and auricleless leaf . Its heading date was April 23 and maturingdate was May 25 in paddy field, 3 days and 1 day earlier than ‘Youngyang’, respectively. The cultivar showed 90cm of culmlength, 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 (TotalDigestible Nutrients) and grade Ⅱ of silage quality. This cultivar would be suitable for the area above the daily minimumtemperature of -8℃ in January in Korean peninsula.
