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.
