‘미한’은 추위 및 도복에 강한 다수성이면서 총체적성이 우수한 청보리 품종육성을 목표로 2001년 추위 및 도복에 강하며 초형이 양호한 ‘SB00T2064’를 모본으로, 양질다수성으로 총체적성이 우수한 ‘수원385호(IT215831)’를 부본으로 인공교배하였다.‘익산487호’로서 전국 6개소에서 2014년부터 2016년까지 지역적응시험을 거쳐 2016년에 육성되었다. ‘미한’은 기존 육성된 ‘영양’의 거친 망의 단점을 개선하여, 까락의 거치가 적은 반매끈망의 특성을 지니고 있다. 미한’은 직립 초형으로 파성은 IV정도로 영양보다는 추파성이 강하였다. 미한의 잎은 녹색이며, 엽폭은 중간정도이며, 엽이의 안토시아닌색은 없으며, 초장은 96㎝, ㎡당 경수는 665개로 표준품종인 ‘영양’ 보다 적었으나, 엽신 비율이 17.9%, 이삭비율은 52.2%로 높다.
답리작(전주 등 5개 지역 평균)에서 출수기는 4월 23일로 ‘영양’보다 3일 늦었으나, 황숙기는 5월 23일로 ‘영양’보다 1일 늦었다. ‘미한’은 내한성에 대해서는‘영양’보다 강하며, 흰가루병에는 약하며, 보리호위축병에 저항성을 나타냈다. 건물수량은 전작에서 13.9톤/ha으로 ‘영양’과 보다 5% 감수하였지만, 답리작에서 10.9톤/ha으로 ‘영양’과 같았다. 조사료 품질은 조단백질 함량이 10.3%로 ‘영양’에 비해 높았으며, ADF는 26.1%, NDF는 46.9%로 ‘영양’보다 높았으며 TDN이 68.2% ‘영양’보다 다소 낮았으나, 사일리지 품질등급은 I 등급으로 ‘영양’보다 우수하였다.

A new barley (Hordeum vulgare L.) cultivar 'Mihan' having ruminant-palatable semi-smooth awn and good silage quality was developed at National Institute of Crop Science(NICS), RDA in 2016. This cultivar was derived from a cross of the 'SB00T2064' and 'Suwon385' in 2001. And its promising line showed high yielding through the preliminary yield trials(PYT) and advanced yield trials (AYT) in Iksan from 2012 to 2013. It was designated as the ‘Iksan487’. ‘Iksan487’ was conducted to regional yield trials (RYT) in one upland field and five paddy fields around Korea for three years from 2014 to 2016. And it was released as the name of 'Mihan'. It has growth habit of IV, erect plant type, green leaf and semi-smooth awn. Its heading date was April 23 in the paddy field and maturing date was May 24. Plant height of ‘Mihan’ was 96cm. Mihan’s spikes per ㎡ was 665. It has better winter hardiness and resistance to BaYMV (Barley Yellow Mosaic Virus) than that of barley cultivar 'Youngyang'. The average dry matter of 'Mihan' was about 10.9 ton ha-1 in paddy field. And average feed quality of ‘Mihan’ was 10.3% of crude protein content, 26.1% of ADF (Acid Detergent Fiber), 46.9 % of NDF (Neutral Detergent Fiber) and 68.2% of TDN (Total Digestible Nutrients). ‘Mihan’ had grade I of silage quality. This cultivar would be suitable for the area above the daily minimum average temperature of -8℃ in January in Korean peninsula.
