Simple sequence repeat allele sizes in base pairs (bp) for markers mapping near the fire blight resistance QTL on Linkage Group 3 of apple.
¹ The physical position of the markers is based upon the whole genome sequence of ‘Golden Delicious’ [33] with 200kbp gaps inserted between scaffolds [104].
² Analyses were performed in duplicate. The alleles are not corrected to their true size.
