영문 초록

Potato late blight caused by the fungus Phytophthora infestans is one of the most important diseases worldwide. Developing potatoeswith resistance to late blight through breeding programs is a key research interest in Korea. ‘Mangang’ was bred for late blight resistancethrough a breeding program at the Highland Agriculture Research Institute of National Institute of Crop Science. The population derived fromthe cross between ‘Atlantic’ as the female parent, which has excellent chipping quality and ‘CIP393371.159’ as the male parent, a late blightresistantclone introduced from International Potato Center (CIP), was selected. In ‘Mangang’, the plant maturity occurs late and the growth habitis of the erect type. The tuber shape is round and eye-depth is medium. The skin color of ‘Mangang’ is light yellow; however, there arepink spots around the eyes of the tuber, and the flesh color is white. Leaf color is green and flower color is light-purple. ‘Mangang’ exhibitsresistance to early blight (Alternaria solani) and leaf roll virus (PLRV). In addition, it has moderate resistance to common scab (Streptomycesscabies). The response to late blight was evaluated in a non-agrochemical treated field for five years between 2012 and 2016; ‘Mangang’exhibited resistance to late blight. The mean AUDPC (Area Under Disease Progress Curve) values of ‘Mangang’ and ‘Atlantic’ were 165.5 and795.8, respectively. Total tuber yield from the non-agrochemical application trial at three regions during the five years was 40.3 ton/ha; thiswas 40.4% higher than that from ‘Atlantic’. The dry matter content of ‘Mangang’ was 21.3%, which was slightly higher than that of ‘Atlantic’. The chip color was 66.5, and the chip processing quality of ‘Mangang’ was at a level similar to that of ‘Atlantic’ (Registration No. 9312).
