Construction of genetic linkage maps and QTL analysis for bacterial wilt (CBW) resistance and anthocyanin pigmentation contents in petals (CAP) in carnation. Two populations were used for the 85P population, which was derived from a cross between line 85–11 and ‘Pretty Favvare’, and the NP population, which was derived from a cross between ‘Carnation Nou No.1’ and ‘Pretty Favvare’. Linkage groups (LGs) were designated as 85P_1 to 85P_15-2 for the 85P map, and as NP_1 to NP_15 for the NP map. Genetic distances (cM) and SSR loci are listed on the left and right sides of each LG, respectively. Distorted segregation is indicated by a significant P value in the chi-square test: ^*, P < 0.05; ^**, P < 0.01. Published loci previously reported by Yagi et al. [14, 15] are underlined. SSR loci common to both maps are indicated in red and connected with lines. STS loci designed by De Benedetti et al. [20] are shown in blue. Boxes indicate QTL regions with LOD values greater than thresholds (in Table 3). Tightly linked markers identified in previous reports [14, 15] are indicated in bold. Single flower locus in Onozaki et al. [18] is shown as “d” on LG NP_15.
