| Popis: | Here we report the identification of a new resistance gene (Vd3) against apple scab (Venturia inaequalis) from the apple selection 1980-015-25 of the breeding program at Plant Research International. This accession also contains the Vf gene. We mapped Vd3, using SSR and DArT markers, on linkage group 1, at a distance of 6 cM from Vf gene, but in repulsion phase to Vf. Based on pedigree analysis and resistance tests, it could be deduced that 1980-015-25 had inherited Vd3 from the founder D3. This gene provides resistance to the highly virulent EU-NL-24 strain of the race 7 of V. inaequalis. This strain has overcome the resistance from both Vf and Vg. However, Vd3 has been not effective against the majority of other V. inaequalis strains we used in our disease tests. |
