A New Whole Crop Barley Cultivar 'Younghan' with Good Quality, Resistance to Lodging and Viral Disease and High-Yielding
pp.184-189
신품종 '영한'은 병해 및 도복, 한해 등 재해에 강해 수량이 많고 품질이 우수한 청보리 품종을 육성하기 위하여 1997년에 조숙, 내도복, 내병, 다수성 계통인 'YB3433-3B-5'와 조사료 품질이 좋고 수량이 많은 'YB3135-3B-2-3' 사이의 F1에 'YB3135-3B-2-3'를 여교잡하고 계통육종법에 의하여 제반특성이 우수한 'SB971305-B-B-B-B-4-4' 계통을 선발, 생산력검정시험과 지역적응시험을 거쳐 2008년에 육성되었다
Younghan' (Hordeum vulgare L.), a winter barley for forage use, was developed by the breeding team at the Department of Rice and Winter Cereal Crop, National Institute of Crop Science, Rural Development Administration in 2008. It was derived from a cross between F1['YB3433-3B-5'/'YB3135-3B-2-3'] and 'YB3135-3B-2-3'. 'SB971305-B-B-B-4-4' line was selected for its earliness, resistance to disease and good agronomic characteristics. The promising line showed both high yield and lodging resistance in the yield trials in Iksan in 2004 to 2005, and designated as 'Iksan420'. The line was subsequently evaluated for winter hardiness, earliness, and yield at eight locations throughout Korea for two years from 2007 to 2008 and finally named as 'Younghan'. It has the growth habit of IV, erect plant type, green leaf and thick culm in diameter. Its heading date was April 24, and the maturing date was May 25 in paddy field conditions, which were one day earlier than those of the check cultivar 'Youngyang'. The cultivar 'Younghan' had better winter hardiness, and resistance to lodging and BaYMV than those of the check cultivar did. The average forage dry matter yield of 'Younghan' was approximately 12.0 MT/ha in adapted region. 'Younghan' also showed 8.5% of crude protein content, 27.2% of ADF, and 67.1% of TDN, including higher grade of silage quality for whole crop barley. This cultivar would be suitable for (area with daily minimum temperature in January) above -8℃ in Korean peninsula.
