1 Introduction The use of high altitude mountainous areas to breed a season seed in summer can not only solve the difficulty of seed storage in summer but also accelerate the breeding of detoxification seed to meet the needs of potato in winter and spring for virus-free seed. In 2000-2002, we conducted a summer trial of virus-free potato varieties in high-altitude mountainous areas of Shanghang, Zhenghe and Dehua in Fujian Province and achieved successes. The yield reached 1139 5-1815 7k
