A new double cropping potato cultivar ‘Goun’ was developed by Highland Agriculture Research Center, National Institute of Crop Science (NICS), RDA in 2007. This cultivar was obtained from the cross between ‘Chubaek’ and ‘Lemhi russet’in 1998. The seedling and line selections were performed from 1999 to 2000, preliminary and advanced yield trials were carried out from 2001 to 2004, and the regional yield trials were conducted at three locations from 2005 to 2006. ‘Goun’ has white flower, green wide leaflet and petiole, short oval tuber with beige skin and white flesh. This cultivar has mid resistance to common scab and potato leaf roll virus. The dry matter content were 20.4 and 21.4% in spring and autumn season, respectively,which were similar with those of ‘Atlantic’ and higher than ‘Dejima’. Also, the potato chip color of ‘Goun’ was similar with that of ‘Atlantic’ in spring and autumn season. The dormancy of ‘Goun’ was 60～70 days after harvest, which was 5～10 days longer than ‘Dejima’. The average yield of tubers in spring and autumn season were 33.2 and 26.3 ton/ha in the regional yield trials, which were 13% and 14% lower in spring and autumn season, respectively compared to ‘Dejima’. ’Goun’ can be used for the potato chip processing and table stock after autumn cultivation in potato double cropping area of Korea.
