Figure 3.

Linkage maps of the BC₁ and BC₂ populations based on 100 and 458 individuals, respectively: Linkage groups 5-6. Markers are shown on the left of the bar and their positions on the right in cM. The added virtual markers on the BC₂ map with missing scores are underlined. Vigour QTLs as mapped in BC₁S₁ and BC₂S₁ families under non-stress (black), drought (red), salt (blue) and nutrient deficiency (green) conditions are shown next to the marker positions. Open QTL block indicates a positive additive effect for the wild allele, and closed QTL block indicates a positive additive effect for the crop allele. Trait abbreviations: L: plant length, FW: fresh weight, DW: dry weight, RMC: relative moisture content.
