<p>The present invention relates to a method for preparing fertility-lowered plant. The present invention provides an RNA interference vector and a method for obtaining a transgenic plant by introducing said RNA interference vector into a target plant; said transgenic plant is the following 1) or 2): 1) Sterile transgenic plant or 2) The fertility of said transgenic plant is lower than said target plant; the present invention also provides a method for cultivating a target plant to a sterile mutant or fertility-lowered mutant by sodium azide mutagenesis. The experiments of the present invention proved that the present invention provides various methods for preparing sterile lines or fertility-lowered lines; including RNA interference or TILLING (Targeting Induced Local Lesions IN Genomes) technology selection; sterile lines prepared by the methods of the present invention establish the basis of rice heterosis and crossbreeding.</p>
