Fig. 2 Two marker locus-QTL associations for resistance to Xanthomonas campestris pv. phaseoli (Xcp) previously identified in the BAC 6 x HT 7719 population across the RI populations of Venezuela 44 x BAC 6 (VB), Belneb RR-1 x A55 (BA), and BAC 6 x HT 7719 (BH) and in the BC2F3 population of PC 50 x BAC 6 (PB). The most likely locations of QTL based on single-factor ANOVA in each population are indicated by oval shapes. Markers common to linkage groups constructed for different populations are connected by lines
