초록

청보리 신품종 '미호'는 까락에 거치가 적은 반매끈망으로 부드럽고 엽신비율이 높으며, 내한성에 강하고 경수가 많은 다얼성으로 총체 건물수량이 높은 품종이다. 이 품종은 2001년에 'SB00T2040'을 모본으로 하고, 'SB941003'을 부본으로 인공교배하여 육성선발된 '익산 473호'를 2012년 부터 2014년까지 전국 6개소에서 지역적응시험을 거쳐 2014년에 육성되었다. '미호'는 직립초형이고 파성이 III 정도이며, 잎은 녹색이고 옆폭은 중간 정도이다. 엽이에는 색소 침착이 없고, 까락특성은 거치가 적은 반매끈망이다. 초장은 96 cm로 장간 품종에 속하고, $m^2$당 경수는 650개로서 '영양'의 593개 보다 57개가 많은 다얼성이다. 출수기는 전작에서 4월 28일, 답리작에서는 4월 27일로 표준품종인 '영양'보리와 같았고, 황숙기는 전작에서 6월 1일로 '영양'보다 1일 늦었고, 답리작에서도 5월 29일로 1일 늦었다. '미호'는 영양보다 내한성이 강하였고, 흰가루병에는 감수성을 나타내었지만 보리호위축병은 익산(III)에서 중도저항성, 나주(I), 진주(IV)에서는 저항성을 보였다. 건물수량은 전작에서 평균 13.1톤/ha, 답리작에서 평균 12.1톤/ha으로 '영양'에 비하여 각각 9%, 2% 증수하였다. 조사료 품질은 조단백질 함량은 6.8%로 '영양'에 비해 낮았고, ADF와 NDF 함량은 각각 27.1%, 49.4%로 '영양'에 비해 다소 높았으나, TDN 수량은 8.3톤/ha로 '영양'보리와 대등하였다. 사일리지 품질은 2등급으로 양호한 발효양상을 보였다.

The purpose of development new variety 'Miho' (Hordeum vulgare L.) is a favorite with livestock feed and develop varieties resistant to disease and lodging. 'Miho' was carrying out the growth habit of group III with green and mid-wide leaf. Awn that is related to preference of livestock is a semi-smooth awn. This cultivar had 96 cm of culm length, 650 of spikes $per\;m^2$. Heading date of 'Miho' was April 27, and maturing date on May 30, which were later than cultivar 'Youngyang'. It also showed strong winter hardiness, and similar resistance to shattering and bariy yellow mosaic virus (BaYMV) compared with those of check one. The best thing among the traits of a good quality with the plant green at the latter growing period. The average forage dry matter yield in the regional yield trial was about 13.1, 12.1 MT per ha in upland and paddy field, respectively, which were 9%, 2% higher than that of the check cultivar. It's also showed 6.8% crude protein, 27.1% ADF (acid detergent fiber), and 67.5% TDN (total digestible nutrients), including higher silage quality for whole crop barley. This cultivar would be suitable for the area whose average minimum temperature was above $-8^{\circ}C$ January in Korean peninsula.
