This invention pertains to methods for determining the presence or absence inplant material of elite event MS-B2, which is a specific transformation event of a construct comprising a male-sterility gene, at a specific location in thegenome, using PCR and primers specific to the construct, and kits for use in the methods.

Methods for determining the presence or absence of elite event MS-B2 in Brassica plant material

This invention relates to transgenic Brassica plants, plant material and seeds, characterized by harboring a specific transformation event, particularly by the presence of a male-sterility gene, at a specific location in the Brassica genome. The invention also relates to the seed deposited a the ATCC which will grow into a male sterile, herbicide resistant plant. The invention further provides a process producing a transgenic cell of a Brassica plant and a method of identifying a transgenic plant, or cells or tissues thereof. A kit for identifying the transgenic plants comprising the elite event of the prsent invention is also described. The Brassica plants of the invention combine the male-sterility phenotype with optimal agronomic performance, genetic stability and adaptability to different genetic backgrounds.
