A method for editing a plant genome includes coating a microparticle with at least one type of nucleic acid and/or at least one type of protein, introducing a deletion, insertion, or substitution into a target site in the genome of a plant by bombarding a shoot apex of the plant with the coated microparticle using a gene gun, growing the shoot apex bombarded with the coated microparticle to obtain a plant body, and selecting a genome-edited plant body from the plant body. The shoot apex of the plant is selected from the group consisting of a shoot apex of an embryo of a fully mature seed, a shoot apex of a young bud of a tuber, and a shoot apex of a terminal bud or a lateral bud.
