Potato, Solanum tuberosum L., is the most important non-grain food crop in the world, which produces more food per unit of production area than any cereal crop and significantly contributes to global food security. Potato domestication originated in a cool climate region of the Andes and, due to its narrow genetic basis of heat tolerance traits, this vegetable species is highly susceptible to heat stress. High-temperature stress delays sprout emergence, reduces leaf size, total leaf area, the number of stolons, the number and mass of tubers, and causes tuber disorders, consequently reducing the total and marketable yield of potato. Heat stress also negatively affects the nutritive and processing qualities of tubers. Due to global climate change, and the continuous rise in the Earth's surface temperatures, the detrimental effects of heat stress on potato crop are intensifying. At the same time, world population growth requires a significant increase in potato production. Thus, solutions for mitigating the damage of high-temperature stress on potato productivity are essential. In the past decades, various researches on the effects of high temperatures on potato plants have been conducted, and significant progress towards understanding the mechanisms underlying potato heat stress responses at the whole plant and molecular levels has been made. This chapter summarizes the current knowledge of the effects of heat stress on potato growth, development, productivity and nutritive qualities, and mechanisms associated with potato heat susceptibility. Future research directions and the development of potato varieties with improved heat tolerance are also discussed.
