‘조풍’은 농업적 특성과 조사료 생산성이 우수하여 도입귀리를 대체할 수 있는 남부지방 적응 추파용 우량품종을 육성할 목적으로 1999년에 조숙이면서 종실이 대립인 ‘아리80’에 대립종인 ‘귀리23호’를 교배한 F1 잡종을 모본으로 하고, 내한성인 미국 도입종 ‘Walken’를 부본으로 온실에서 인공교배하여 집단 및 계통육종법에 의해 계통을 선발한 후 2004년부터 생산력검정시험 및 지역적응시험을 거쳐 2009년에 육성된 품종으로써 주요 특성은 다음과 같 ‘Jopung’ (Avena sativa L.), a winter oat for forage use, was developed by the breeding team at the Department of Rice and Winter Cereal Crop, NICS, RDA in 2009. It was derived from an original cross between the F1 hybrid of ‘Early80’ and ‘PA202-210-S’ and ‘Walken’ in 1999. Subsequent generations followed by the cross were handled in bulk and pedigree selection programs at Suwon and Yeoncheon, respectively. A line, ‘SO99006-B-YB-29-Y1’, was selected for earliness and good agronomic characteristics and designated as a line name of ‘Gwiri65’. The line ‘Gwiri65’ was subsequently evaluated for earliness and forage yield in four different locations, Yesan, Iksan, Kimjae, and Jeju, from 2007 to 2009 and finally named as ‘Jopung’. Over 3 years, the average forage dry matter yield of cultivar ‘Jopung’ harvested at milk-ripe stage was 17.3 MT ha-1, compared with 13.6 MT ha-1 of check cultivar ‘Swan’. The silage quality of ‘Jopung’ was superior to the check cultivar ‘Swan’ in crude protein content, and was similar to the check cultivar in percent total digestible nutrients (TDN). Cultivar ‘Jopung’ is suitable primarily for winter planting in the southern regions of Korean peninsula.
