Improvement of winter hardiness, lodging resistance and good quality have been recently received more attention by covered barley(Hordeum vulgare L.) breeders than ever in Korea. ‘Hyeyang’, a new covered barley cultivar with early maturing and high yield was developed by the National Institute of Crop Science, RDA in 2010. It was derived from the cross between‘Milyang87’and‘Wolsung8120’with good quality. The initial cross was done in 1999 and the selected line, ‘Iksan432’ (YB4494-B-B-21-2), showed high yield and good quality characteristics under yield trial test from 2008 to 2010. The following is the characteristics of‘Hyeyang’that is characterized as the vernalization of I, green leaf, compact spike and long rough awns. The heading date of‘Hyeyang’were similar to‘Olbori’. The culm length was 82 cm which was 6 cm shorter than‘Olbori’. It showed the spike length of 4.3 cm, 798 spikes / m², 56 grains / spike and 26.7 g for 1,000 grains weight. It showed similar winter hardiness and stronger resistance to barley yellow mosaic virus (BaYMV) compare to‘Olbori’. It showed higher diastatic power 235DP than that of check cultivar, ‘Olbori’. Average yield of ‘Hyeyang’ was 4.44 MT/ha in the regional yield trials carried out in four location at double cropping system in Korea from 2008 to 2010, which was 8 percent higher than ‘Olbori’. ‘Hyeyang’would be suitable for the area above –8°C of daily minimum temperature in January in Korean peninsula.

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

‘Boanchal’, a new covered waxy barley cultivar derived from crossing the ‘Suwon232’ and ‘Masangwamaeg’ with early maturing and colored waxy endosperm cultivars, respectively was developed at the National Institute of Crop Science, RDA in 2009. ‘Boanchal’ is characterized as the growth habit of Ⅲ, green leaf, medium spike and long rough awns. The heading date was April 24 in upland and April 17 in paddy field which was 2 and 1 day, respectively earlier than check cultivar, ‘Seodunchal’. The culm length of ‘Boanchal’ was 79 cm, which was 11 cm shorter than that of check cultivar. It showed spike length of 3.5 cm, 854 spikes per m², 43 grains per spike, and 28.0 g of 1,000-grain weight. Comparing to check cultivar, ‘Boanchal’showed stronger winter hardiness, but a similar resistance to barley yellow mosaic virus (BaYMV). It had purple grain and showed higher expansion rate than that of check cultivar, ‘Seodunchal’. Average yield of ‘Boanchal’ in the regional adaptation yield trial (RYT) was 2.96 MT/ha in upland and 3.91 MT/ha in paddy field. ‘Boanchal’ would be suitable for the area above -8°C of daily minimum temperature in January in Korean peninsula.
