This study includes the transformation of genes such as ORE7, the increase of gene expression, and the use of the bar gene as a selectable marker that shows herbicide resistance with Agrobacterium tumefaciens using hypocotyls from the oilseed rape “Youngsan” cultivar. To establish an Agrobacterium transformation system for the production of oilseed rape with a high-yield trait, infection time and co-cultivation period with Agrobacterium were tested. Therefore, when hypocotyls from the oilseed rape “Youngsan” cultivar were infected with Agrobacterium for 20 min and co-cultivated for 3 days, approximately 32-36 putatively transformed hypocotyls with shoots including roots survived from 100 inoculated hypocotyls after 4 weeks of trans- formation on a selection medium containing 20 mg/L of phosphinothricin (PPT) as a selectable agent. Additionally, a PCR assay was performed to confirm the insertion of target genes and showed the presence of the ORE7 gene as a high-yielding trait and the bar gene as a selectable marker. Treatment with 0.5% (v/v) Basta solution as a selectable agent for 6 days with leaves from transformed oilseed rape expressed the bar gene. Therefore, this study can contribute to the development of special oilseed rapes containing agri- culturally useful traits such as herbicide resistance, drought tolerance, high yielding traits, and high oleic acid content.
