Lately, the autumn cropping areas of potato have been steadily increased to supply fresh potatoes all year round in Korea. Although "Dejima" is a main cultivar for autumn cropping, it is very susceptible to common scab (Streptomyces scabies) and show high frequency of physiological disorders such as knobs and cracking on tubers. "Chudong" was bred in 2002 for fresh table use from a cross between H83520-3 with short tuber dormancy and "Superior" with common scab resistance. It has attractive, round tuber shape with white skin and flesh colors. Its tuber dormant periods is 5 days longer than 65 days of "Dejima". Its average yields were 32.4 and 21.8 ton/ha at 90 days after planting in spring and autumn cropping of regional yield trials, respectively. It is more resistant to common scab and potato leaf roll virus and less susceptible to late blight (Phythophthora infestans) compared to "Dejima". However, it is susceptible to potato virus Y.
