Hybrid winter oilseed rape and methods for producing same

This invention relates to transgenic winter oilseed rape (WOSR) plants, plant material and seeds, harboring a specific transformation event. It pertains to winter oilseed rape plants, more particularly to a pair of winter oilseed rape plants, which is particularly suited for the production of hybrid seed. More specifically, one plant is characterized by being male-sterile, due to the presence in its genome of a male sterility gene, while the other is characterized by carrying a fertility-restorer gene, capable of preventing the activity of the male-sterility gene. The invention further provides a method for producing hybrid seed, a process for producing a transgenic WOSR plant oil or plant, and a method to identify a transgenic plant, cell or tissue. A kit for identifying the transgenic plants comparing the elite event of the present invention is also described. The WOSR plants of the invention combine the ability to form hybrid seeds with optimal overall agronomic performance, genetic stability and adaptability to different generic backgrounds.
