Genetic linkage map of Pop-DG with fruit texture, flavor, pigment, and CI resistance genes. Pop-DG = 'Dr. Davis × 'Georgia Belle'. Open vertical bars represent linkage groups. Vertical solid bars represent linkage groups of the T × E Prunus reference map (Dirlewanger et al. 2004; Howard et al. 2005) showing the bins and anchored with linkage groups of Pop-DG. Positions of SSR markers on the T × E map corresponding to the Pop-DG map are connected by dotted lines. Genetic markers are to the right side of each linkage group of Pop-DG, genetic distances (cM) are to the left. Markers in bold are fruit texture, pigment, flavor, and CI resistance candidate genes. Markers with prefix 'C-' are novel Prunus EST-SSRs obtained from the ChillPeach database (Ogundiwin et al. 2008). RAF and SRAP markers start with prefixes 'r' and 's', respectively. Accessory markers are italicized. Markers in blue fonts were heterozygous in 'Georgia Belle' only, markers in red fonts were heterozygous in 'Dr. Davis' only, and all other markers were heterozygous in both parents.
