A large quantity of potato microtubers can be produced easily and in a short period of time by a method of production comprising a first step wherein potato plants are cultured in a medium with a relatively low sugar concentration under a relatively large quantity of light irradiation per day and a second step wherein the resultant potato plants are cultured in a medium with a relatively high sugar concentration under a relatively small quantity of light irradiation per day, the culture in the first step being carried out in the presence of exogenous ethylene and the culture in the second step being carried out in the absence of exogenous ethylene. |
