초록
‘Joan’, a rapeseed (Brassica napus L.) F1 hybrid cultivar suitable for producing cooking oil developed by the National Instituteof Crop Science, is early maturing with characteristically high yield and oleic acid content. It was bred in 2009 by crossing the male sterileline ‘Mokpo-CGMS’ as the female parent with the restorer line ‘8630-B-6-5-3-6’ as the male parent. The average flowering and maturationdates of ‘Joan’ were April 10th and June 1st, respectively, 3 and 4 days earlier, respectively, than that of the control cultivar ‘Sunmang’. The yield of ‘Joan’ obtained in regional adaptation trials was 279 kg/10 a, which is 6% higher than that obtained for ‘Sunmang’. ‘Joan’is resistant to stem rot disease and more tolerant to lodging than ‘Sunmang’. Moreover, the total oil content of ‘Joan’ is 44.5%, whereasthe oleic acid content is 69.5%, which is 2.3% higher than that of ‘Sunmang’. However, erucic acid has not been detected. ‘Joan’ can begrown in paddy fields located in Jeollanam-do, Jeollabuk-do, Gyeongsangnam-do, and Jeju-do in Korea (Registration No. 6896).
