A family 1 cellulose-binding-domain (CBD) encoding gene from Phytophthora infestans was used to develop transgenic Bintje potato plants. Tests with detached leaflets showed no evidence of increased or decreased resistance to P. infestans, in comparison with the susceptible Bintje controls. Changes in plant morphology were most evident in the CBD1 multicopy transgenics. Plant height increases were evident in the later growth stages, along with earlier flowering and the ability to produce seed balls. While Bintje control plants are male and female sterile, the multicopy transgenics were male sterile and female fertile. Crosses made into Bintje demonstrated the ability to transfer P. infestans targeted R genes, as well as genes responsible for color and tuber shape, into Bintje germplasm. Selection for the absence of the CBD1 transgene should allow for immediate use of the material.
