영문 초록

‘Dami’ was released by the potato breeding program at the National Institute of Highland Agriculture (NIHA), National Institute of Crop Science, Rural Development Administration. To develop a potato cultivar suitable for spring and summer cropping with good taste, a cross of ‘Daegwan 1-97’ × ‘Daegwan 1-98’ was made in 2005. One of the progenies selected, clone number P05855-18, was validated for key agronomic characteristics required for spring cultivation in Gangneung and summer cultivation in Pyeongchang from 2009 to 2011. Subsequently, P05855-18 was advanced to nationwide field trials and renamed as ‘Daegwan 1-121’. Regional adaptations of ‘Daegwan 1-121’ were tested in Cheongju, Najoo, Gangneung, and Pyeongchang between 2012 and 2014, and finally registered as a potato cultivar, ‘Dami’, based on key agronomic characteristics, including mid-maturity, semi-erect growth habit, and consumer traits including round tuber and very shallow eye-depth. ‘Dami’ has yellow skin and white flesh. The leaves are green, and white flowers bloom abundantly. Physiological tuber disorders, such as malformation, cracks, and internal defects, were less frequently observed than those in ‘Superior’. ‘Dami’ was moderately resistant to potato late blight and viruses. The average tuber yield was approximately 5% higher than that of ‘Sumi’ and the dry matter content was approximately 20.5%. The taste of the boiled whole potato was considered excellent, owing to floury characteristics, and the potato was suitable for table usage (Grant No. 6926).
