A gene RAP7(rice after pollination clone 7) for regulating height of rice is provided to improve resistance against lodging caused by typhoon or localized torrential rainfall in rice by overexpressing the gene in rice to induce semi dwarf rice through genetic engineering technique, so that quality and crop yield of rice are improved. A recombinant vector for transformation contains the RAP7 gene comprising nucleotide sequence of SEQ ID NO:1 and having regulating activity of plant height in rice. A transformant is produced by introducing the recombinant vector to a host cell by using Agrobacterium tumerfaciens LBA4404. A transgenic Oryza sativa L. having resistance against lodging is produced by transforming the Oryza sativa L. with the recombinant vector by using Agrobacterium tumerfaciens LBA4404.
