Foot potato has strong adaptability and wide planting distribution, widely distributed in temperate and tropical regions of the world, mainly produced in tropical and subtropical regions, and cultivated in Guangdong, Jiangxi and Fujian. Footboard potatoes have a short growth period, and can be harvested in 4-6 months from planting to harvesting. Early-maturing scorched potato tubers began to grow in August and matured in early February. However, compared with the early-maturing type, the tubers of middle-maturing or late-maturing type start to grow later and keep growing until harvest. Foot-board potato has a high yield, the tuber yield per plant can generally reach 10kg, and the high-yield potato yield can even reach 50kg.
