초록
‘중모 7002’는 유채 중간모본으로 1984년에 ‘RS10//Erra/ Tower’를 모본으로 하고, ‘RS10’을 부본으로 하여 인공교배하여 육성하였다. ‘중모 7002’는 엽형은 하부익상전렬으로 결각은 중간이며, 잎색은 짙은 녹색, 줄기색은 갈색이 섞인 녹색, 꽃색은 황색, 종피색은 흑색이다. ‘중모 7002’의 개화기(4 월 16일)와 성숙기(6월 9일)는 ‘한라유채’와 비슷하였으나, 개화초기에 일시에 개화하는 개화균일도가 매우 좋았으며, 도복저항성도 ‘한라유채’에 비하여 좋게 나타났다. ‘중모7002’ 의 수량은 지역적응시험 결과 10 a당 247 kg로 ‘한라유채’의208 kg에 비해 16% 증수되었다. ‘중모 7002’의 기름함량은44.3%이고, 올레인산의 함량은 70.8%로 ‘한라유채’에 비하여 각각 0.5%와 3.3% 높게 나타났으며, 구루코시노레이트함량은 1.91 mg/g으로 국제허용기준치인 3.0 mg/g 이하로나타났다. ‘중모 7002’의 재배적지는 우리나라의 서남부지역인 전라남도, 전라북도, 경상남도 및 제주특별자치도이다.
Abstract
‘Jungmo 7002’ is a intermediate parent of rapeseed (Brassica napus L.) with flowering uniformity and lodging tolerance for the scenery and oil production. ‘Jungmo 7002’ was developed from the cross between ‘RS10//Erra/Tower’ as female parent and ‘RS10’ as male parent in 1984. A promising line, ‘84013-B-6-3-3-6’, was selected and designated as the name of ‘Mokpo116’. It was prominent and had good result from regional adaptation yield trials (RYT) for three years from 2011 to 2013 and was released as the name of ‘Jungmo 7002’. ‘Jungmo 7002’ has middle parted and dark-green leaf, Brownish-green stem, yellowish flower and black seed coat. The flowering date of ‘Jungmo 7002’ was 16th April and ripening date was 9th June. The yield of ‘Jungmo 7002’ was 247 kg/10a, which was 19% higher than ‘Hanlayuchae’ in regional adaptation trials. This intermediate parent showed high resistance to lodging tolerance. The oil content of ‘Jungmo 7002’ was 44.3%. In fatty acid composition of ‘Jungmo 7002’ , oleic acid content is 70.8%, which is 3.3% higher than ‘Hanlayuchae’. And ‘Jungmo 7002’ has no erucic acid. ‘Jungmo 7002’ will be adaptable to southwestern area including Jeonllanam-do, Jeollabuk-do and Gyeongsangnam-do and Jeju island of Korea.
