Introgression of Powdery Mildew Resistance from Rye into Wheat

(...) The chromosome 2R of the 2D/2R substitution line showed the typical C-banding pattern after differentially staining the constitutive heterochromatin. The rye chromosome 6R conditioned absolute resistance to all powdery mildew isolates tested and is shown to be located at the long arm of that chromosome. For this resistance, we propose the temporary gene symbol MlP6L. In addition, we present a way of transferring this resistance gene using a 6BS/6RL wheat-rye translocation line
