A new cultivar Jeseo was bred in the potato breeding program of Jeju Special Self-governing Province Agricultural Research and Extension Services. It was originated from two backcrosses made in 1999 and 2001 between somatic hybrid as a female and Dejima as a male parents. The Jeseo was evaluated as a seedling for tuber characteristics, disease resistance, growth and yielding ability from 2001 to 2005. This clone was evaluated in the regional yield trials at 4 locations for 2 years. The tuber characteristics of this cultivar have a round, shallow eye depth, yellow-skinned, and short dormant period. And also, it showed high resistant to potato common scab (Streptomyces scabies, S. turgidiscabie and S. acidiscabie), soft rot, and Potato leaf roll virus (PLRV). However, it was susceptible to Potato virus Y (PVY) and late blight (Phytophthora infastans). The mean tuber yield of Jeseo according to the spring and fall cropping during the 2012 was 38.8 ton per hectare, which was lower than that of Dejima
