Fine mapping of the Ru_RGT locus on chromosome 12. Partial bottom region of the RGT LG12 is reported on the top as a horizontal bar. Genetic distances in cM between SSRs were calculated using recombination events occurred across 287 individuals from RGTxGD (code 99411) and RGTxGRH (code 99412) crosses. Recombinants between CV082939 and Hi07f01 SSRs are indicated on the left as well as the corresponding phenotype assessed for RGTxGD progeny according to [30]; brown bars represent the russeting haplotype, while green bars the alternative haplotypes. The restricted Ru_RGT locus is delimited by dotted vertical lines. Physical representation of the Ru_RGT locus is presented at the bottom according to the GDR Gbrowse; yellow rectangles represent annotated genes, while the position of SSR markers within the locus is indicated according to the Golden Delicious v1.0 assembly
