Abstract

In Korea, domestic consumption of barley as a cereal crop has been decreasing since the 1980s. It has been considered that winter-season crop production could enhance the global competitiveness of domestic livestock industry by providing better quality fodder to livestock and enhancing field use rate. Therefore, the purpose of barley cultivation for cereal food production has been recently replaced by the production of forage barley. Consequently, the area of barley cultivation for forage is markedly increasing in Korea. Forage barley is cultivars especially as forage for cattle. While any type of barley can be used as forage for feeding cattle, forage barleys deliver a higher dry matter yield than conventional feed barley. We have developed forage barley cultivars with cattle's favorite characters such as smooth awn, hood and auricleless types. Cultivar Wooho, Yuyeon, and Dami have smooth awn, hood type spike, and auricleless type plant. We also developed rough awn type barley cultivars, such as Yongyang, Sunwoo, Sangweon, and Soman, showing earlymaturing and high-yielding. They showed about 12 to 10 ton ha-1 in dry matter yield (average 33 ton $ha^{-1}$ in fresh matter yield). And these were evaluated by forage quality which showed a higher grade of silage quality (TDN, ADF, NDF, CP, etc.) for whole crop barley use. Based on these results, it indicated that barley with smooth awn, hooded, and auricleless could be suitable sources in breeding for whole crop forage use.

국내 보리 소비가 급격히 감소하면서 재배 면적도 줄어들어 겨울철 논을 이용한 보리 재배 농가의 대체 소득원이 보리를 활용한 조사료 생산이다. 경지이용률 제고와 양질의 조사료 공급은 국내 축산 농가의 국제경쟁력을 올릴 수 있어 최근 청보리의 생산은 현저히 증가하고 있는 추세이다. 총체사료용 청보리는 식용보리에 비하여 전체적인 건물수량성이 높아야 하고 가축이 먹기에 좋도록 형태적으로도 개선되어야 한다. 그 동안 개발된 총체사료용 청보리는 벼와의 작부체계에 알맞도록 조숙이면서 건물수량이 ha당 10$\sim$12톤 (생체수량 평균 33톤/ha)을 보이는 영양, 선우, 상원, 소만 등을 개발하였으며, 가축의 기호성이 좋도록 거친 까락을 매끈망으로 개선한 우호, 까락이 퇴화한 삼차망 보리 유연과 줄기에 잎귀를 없애서 부드럽게 만든 다미 등 초형을 개선하였다. 이러한 사료 전용 청보리 품종들은 사료가치도 우수한 것으로 평가되어 육종적으로 개선한 각 품종들의 고유 생육특성을 중심으로 보고하는 바이다.
