摘要：
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.
