摘要：

PROBLEM TO BE SOLVED: To provide a method for creating the polyploid of a plant of the genus Pyrus by which the polyploid of the plant of the genus Pyrus can be created artificially, and to provide the polyploid of the plant of the genus Pyrus.

SOLUTION: The method for creating the polyploid of the plant of the genus Pyrus includes a reduced-pressure polyploidization process for treating a bud of the plant of the genus Pyrus with a polyploid inducer under reduced pressure. The reduced-pressure polyploidization process preferably includes a reduced-pressure treatment step of reducing the pressure of the surrounding atmosphere in a state of the bud of the plant of the genus Pyrus soaked in a polyploid-inducing solution containing the polyploid inducer, a normal pressure-returning step of gradually returning the surrounding atmosphere to a normal pressure while keeping the state of the bud soaked in the polyploid-inducing solution obtained in the reduced-pressure treatment step, and a normal-pressure soaking step of keeping the bud obtained by the normal pressure-returning step in the state soaked in the polyploid-inducing solution in the normal-pressure atmosphere for a prescribed time.
