"Chugang" as a new double cropping potato variety for table use was bred in 2003 from a cross between H83005-2 with short dormancy and "Superior" with common scab resistance. It had been evaluated for short dormancy, growth adaptability and tuber characteristics every twice a year from 1990 to 1999. Regional yield trials had been performed from 2000 to 2002 at three locations, Jeju, Namhae and Gangneung of Korea, respectively. It has round oblong tuber shape with yellow skin and white flesh color. Its tuber dormant periods is approximately 50~60 days. It showed less physiological disorders such as cracking or knobs, and more tolerant to environmental stresses such as plant death by flooding and damages by frost or severe wind compared to "Dejima". Average yields of "Chugang" are 34.6 and 31.1 ton/ha at 90 days after planting in spring and autumn cropping, respectively. It is more resistant to common scab and less susceptible to late blight (phythophthora infestans) compared to "Dejima". However, it is susceptible to potato virus Y (PVY) and andean mosaic virus (AMV).
