The invention discloses a planting method of breeder potato seed for reproducing potato rapidly in the current year. The virus-free test-tube plantlets of potato are planted in a tissue culture room during October to December and then transferred to a nutrition pot with nutrition stroma in greenhouse after the test-tube plantlets root. The temperature and the humidity of the greenhouse are controlled and the nutrition stroma is added into the nutrition pot after the plantlets come into three to four leaves. The potato mini tubers can be obtained after the plantlets grow in the nutrition pot for 50 to 60 days and then treated for dormance for 30 to 60 days after being graded. The potato mini tubers are sown into the soil of screen cage with insectproof screen after being treated for dormance and then field cared. The original cuttings are managed by ditching, earthing up, adding water and fertilizer after growing to 9 to 11 cm and the original cuttings can be harvested in October after growing for 4 to 5 months. The invention shortens the cycle of producing potato seeds and can obtain the breeder potato seed the current year.
