국립식량과학원에서 조사료용 조숙호밀을 개발하고자 1995 년에 ‘조춘호밀’등 10개 품종을 방임수분으로 혼합교배하여 그중에서 형질이 우수한 계통(SR95POP-S1-119-2-11)을 선발하여 생산력을 검정한 결과 그 특성이 우수하여 ‘호밀30호’로 계통명을 부여하고 5개 지역에서 4개년간 지역적응성을 검정하여 조숙이면서 조사료 수량이 많을 뿐만 아니라 지역간, 연차간 재배안정성이 높은 것으로 나타나 2006년 직무육성신품종 선정위원회에서 ‘다그린’으로 Dagreen’ (Scale cereal L.), a new rye variety was developed from the open pollination among 10 rye lines at the National Institute of Crop Science in 1995 and mass selection were made at National Institute of Crop Science from 1996 to 1999. Recurrent selections were made at Dept. Rice and Winter Cereal Crop, NICS, RDA from 2000 to 2006. This new variety has erect plant type with medium size pale green leaves. The number of spike per m2 was 713 and the plant height was 103 cm. The heading date of ‘Dagreen’ was April 24 which was 7 days earlier than that of “Koolgrazer”. It was adaptable for forage use at an early stage as a whole crop. Lodging resistance was higher than that of check variety ‘Koolgrazer’. The chemical components and quality of forage showed 10.2 % crude protein, 36.6 % ADF, 62.4 % NDF and 59.9 % TDN. ‘Dagreen’ showed high resistance to powdery mildew and leaf rust than those of check variety in the field condition. The average dry matter (7,010 kg ha-1) of ‘Dagreen’ harvested at April 28 were 6 % higher than ‘Koolgrazer’. This variety is recommended for all of the rye cultivation area in Korea.
