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.

DOI: https://doi.org/10.9787/KJBS.2014.46.3.290

A soybean cultivar for sprout, ‘Joyang 1’ was developed at the National Institute of Crop Science (NICS) in 2010. ‘Joyang 1’ (Iksan67) was released by pedigree selection from the cross between high yielding ‘Pungsannamulkong’ and ‘Suwon187’ tolerant to lodging and disease. It has purple flower, lanceolate leaf, grey pubescence and small yellow seed. Weight of hundred seed is 11.6gram. Maturing date of ‘Joyang 1’ is ten days earlier than check cultivar, ‘Pungsannamulkong’. ‘Joyang 1’ is resistant to bacterial pustule and shattering. It have similar tolerance to root rot and seed spot to check cultivar. It shows high germination ratio, less abnormal germination and hard seed. Sprout yield also 11 percent higher than check cultivar. The average seed yield of ‘Joyang 1’ was 3.03 ton per hectare in the regional yield trials (RYT) carried out for three years from 2008 to 2010 which was 3 percent higher than the check cultivar. The number of breeder’s right is ‘4900’.
