Abstract

A barley(Hordeum vulgare L.) cultivar 'Youjin' with hooded spike type having good silage quality was developed at National Institute of Crop Science, RDA in 2016. 'Youjin' showed both high yielding and cold resistance through the preliminary and advanced yield trials(PYT, AYT) from 2012 to 2013. We conducted regional yield trials(RYT) of 'Youjin' in six locations around Korea for three years from 2014 to 2016. It had erect plant type, growth habit of II, the green leaf and hooded awn type. In the paddy field its heading date was April 24 and the maturing date was May 25. Plant height was 99 cm and the number of spikes per ㎡ was 696. It has high rate of leaf blades, resistance to BaYMV(Barley Yellow Mosiac Virus) and good winter hardiness. The average dry matter of Youjin was about 17.2 MT ha-1 in the field. And feed quality of 'Youjin' was 10.6% of crude protein content, 24.8% of ADF(Acid Detergent Fiber), 43.5 % of NDF(Neutral Detergent Fiber), 69.1% of TDN(Total Digestible Nutrients). And also 'Youjin' had grade I of silage quality.

'유진'은 농촌진흥청 국립식량과학원에서 2005년 삼차망으로 도복 및 내한성이 강하고, 초형이 양호한 수원406호/수원389호의 F1을 모본으로 하고, 장간으로 총체적성이 높은 SB961012/수원389호를 F1을 부본으로 복교잡하여 육성된 '익산488호'로서 2014년부터 2016년까지 전국 6개소에서 지역적응시험을 거쳐 2016년에 육성되었다. '유진'은 직립 초형으로 파성은 II 정도이고, 잎은 녹색이며, 엽폭은 중간정도이다. 초장은 99cm으로 장간에 속하고, ㎡당 경수는 696개로 대비품종인 '유연'보다 적은 경향이었으나, 엽신 비율이 19.0%으로 높은 경향을 보였다. 출수기와 황숙기는 각각 4월 24일과 5월 26일로 '유연'보다는 늦은 경향을 보였다. '유진'은 내한성과 보리호위축병에 대해 저항성을 보였다. 건물수량은 전작에서 17.1톤/ha, 답리작에서 11.0톤/ha로 '유연'보다 각각 19%, 2% 높은 경향을 보였다. 조사료 품질은 조단백질 함량 10.6%, ADF 24.8%, NDF 43.5%, TDN69.1%로 우수한 품질특성을 보였고, 담근먹이 품질등급 I 으로 '유연'보다 우수하게 나타났다.
