Abstract
Sports from two cut rose varieties, as well as a garden rose variety, were analysed with molecular markers. Between 695 and 752 random amplified polymorphic DNA and AFLP fragments were used to infer genetic differences between the sports, the original variety and seedlings of these varieties. Whereas no polymorphisms between the sports of the cut rose varieties and the original variety were observed, five polymorphisms could be detected between the garden rose variety and its sports. In contrast, a large number of polymorphisms occurred between all varieties and their seedlings. Therefore molecular markers can be used to verify the origin of vegetatively propagated rose plants of doubtful origin, thus enabling breeders in the future to claim plant breeders rights on sports of varieties already registered.
