Abstract
'Jomang' is a new $F_1$ hybrid variety of rapeseed (Brassica napus L.) with early maturation, high yield and high oleic acid. This hybrid variety was developed from the cross between Mokpo-CGMS (male sterile line) and 8516-B-5-6-5-3 (restore line) for the production of edible oil and biodiesel in 2006. Yield trials were conducted from 2007 to 2008, and regional adaptation trials were examined at four locations in 2008. 'Jomang' has green and parted leaf, yellowish flower and black seed coat. The ripening date of 'Jomang' is 1~4 days earlier than 'Sunmang' and 'Tammiyuchae'. The average seed yield of the regional adaptation trials was 406 kg/10a, which was 7% and 42% higher than those of 'Sunmang' and 'Tammiyuchae,' respectively. Total oil content of 'Jomang' was 44.5%. 'Jomang' has no erucic acid in fatty acid composition. However, oleic acid content is 68.2%, which is 3.4% and 5.1% higher than 'Tammiyuchae' and 'Sunmang,' respectively. Total glucosinolate content was 2.31 mg/g. Therefore, this variety is recommended as a leading variety at southwestern area including Jeonnam, Jeonbuk and Kyongnam provinces and Cheju island of Korea.
