Abstract

"Jungmo2510", a rye cultivar, Secale cereal L., was developed by National Institute of Crop Science, RDA in 2015. It was developed from open pollination from within 10 rye cultivars or lines including "Chochun" in 1995. The line "SR95POP-S1-523-1-5-5-4-7-3-B-16-3-19" was selected for its excellent agronomic appearance and was placed in yield trials for two years from 2011 to 2012. The line was designated "Homil55" and was placed in regional yield trials at the four locations around Korea from 2013 to 2015, during which time the name "Jungmo2510" was given. This cultivar is an erect plant type and leaves of short and broad size with a green color, a yellow colored, medium-diameter culm, and a yellowish brown-colored, medium-size grain. The heading date of "Jungmo2510" was April 16, which were 2 days earlier than that of "Gogu". "Jungmo2510" also showed similar to winter hardiness and greater resistance to lodging compared to those of the check cultivar. Over three years, the average dry matter yield of "Jungmo2510" was 802 kg 10a-1 , which was harvested in late April and was lower than that of the check cultivar "Gogu" (825 kg). The seed productivity of "Jungmo2510" was approximately 481 kg 10a-1 , which was 2.4% less than that of the check. "Jungmo2510" was higher to than "Gogu" in term of protein content (9.1% and 8.0%, respectively), total digestible nutrients(TDN)(57.5% and 55.5%, respectively), and TDN yield 10a-1(419 kg and 392 kg, respectively). This cultivar is recommended as a fall sowing crop in areas where the average daily minimum-mean temperatures are higher than -12 ℃ in January, and as a winter crop for whole-crop forage before the planting of rice or green manure around Korea.

이 연구는 국내 환경에 적합한 조사료용 호밀 품종을 개발하기 위하여 실시하였다. 잡종은 1995년에 '조춘호밀' 등 10개 품종을 방임수분으로 혼합 교배하여 육성하였으며, 그 중에서 형질이 우수한 'SR95POP-S1-523-1-5-5-4-7-3-B-16-3-19' 계통을 선발하였다. 선발계통에 대해 2011년부터 2년간 생산력검정을 실시하였고, 그 특성이 우수하여 '호밀55호'로 계통명을 부여하고 4개 지역에서 3개년간 지역적응성을 검정하였으며, 2015년에 신품종으로 선정됨과 함께 '중모2510'으로 명명되었다. 호밀 품종 '중모2510'은 초형이 직립이고, 잎색은 녹색이며, 길이는 짧고, 폭은 넓은 편이다. 줄기는 황색으로 중간 정도의 굵기이며, 종실은 황갈색이고, 중간 크기이다. '중모2510'의 출수기는 4월 16일로 표준품종인 '곡우' 보다 2일 빨랐고, 내한성은 표준품종인 '곡우'와 대등한 수준이었으며, 도복은 '곡우' 보다 강하였다. '중모2510'의 건물수량은 10a당 평균 802 kg (곡우 825 kg), 종실수량은 10a당 481 kg(곡우 493 kg)으로 '곡우' 보다 약간 적었다. '중모2510'의 조단백질 함량은 9.1%로 '곡우' 보다 1.1% 높았으며, ADF와 NDF 함량(%)은 각각 39.8%와 65.5%로 '곡우'보다 낮아 TDN 함량(%)이 57.5%로 '곡우'보다 2.0% 높았으며, TDN 수량 또한 10a당 419 kg으로 '곡우' 보다 높았다. 이 품종은 1월 최저평균기온이 -12 ℃ 이상인 지역에서 월동재배가 가능하며, 특히 녹비용이나 답리작 재배를 통한 조사료 생산에 유용할 것으로 기대된다.
