A new rapeseed (Brassica napus L.) F1 hybrid Haean was crossed between Mokpo-CGMS, male sterile line and 8516-B-5-6-1-2, restore line for the adaptation of paddy land culture with early maturing, disease resistant and lodging tolerance in 2008. Yield trials were conducted from 2009 to 2010 in Muan, and regional adaptation trials were examined from 2011 to 2013 in four regions. Haean has dark green, cleft and parted leaf, light yellowish flower, and black seed color. The maturation date of Haean is 4th June, 4 days earlier than Sunmang. In the regional adaptation trials, average yield of Haean was 272 kg/10a, which was 6% higher than Sunmang. Seed oil content of Haean was 44.2%. In fatty acid composition, oleic acid content is 69.8%, which is 2.5% higher than Sunmang. Total glucosinolates content was 1.84 mg/g. Haean has characteristics of disease resistant and lodging tolerance, this variety can be cultured at paddy lands in southwestern area including Jeonnam, Jeonbuk and Kyongnam provinces and Cheju island of Korea.
