영문 초록

‘Saebong’ is a double cropping potato variety bred by the Highland Agriculture Research Institute, NICS, RDA, in 2010. Althoughthe major double-cropped potato cultivar of Korea, cv. Dejima, with a dormancy period of 50-60 days after harvest was introduced in 1978,it is susceptible to physiological disorders, such as abnormal tubers and cracking, and common scab. The ‘Chubaek’ variety matures veryearly and has a dormancy period similar to that of cv. Dejima, yet it is highly susceptible to potato virus Y and has a low dry matter content. ‘Saebong’ was obtained by crossing ‘Daegwan2-8’ with ‘DH9-231’ in 2002. Seedling and line selections were performed from 2003-2004,and yield trials were carried out from 2005-2006 in Gangneung and Pyeongchang. Regional yield trials were conducted in spring and autumnin Namhae, Jeju, and Gangneung from 2007-2008 and in Muan, Jeju, and Gangneung in 2009. This variety produces many white flowersand berries, narrow green leaflets and petioles, and round tubers with beige-colored skin and white-colored flesh. Its dormancy period, whenstored at 20℃, was 50-60 days after harvest in spring, similar to cv. Dejima and Chubaek. The average tuber yields in spring and autumnregional trials were 40.4 and 30.5 ton⋅ha-1, respectively. It is susceptible to common scab but highly resistant to potato leafroll virus andpotato virus Y. Its dry matter content was 21.56% and 20.60% in spring and autumn, respectively (similar to those of cv. Atlantic and cv. Goun). It produces brighter colored potatoes and can be used to process potato chips and table stock after autumn cultivation in the potatodouble cropping area of Korea (Registration No. 4873).
