Framework linkage maps and QTLs from the segregation analysis of the P. deltoides x P. trichocarpa pedigree aligned on P. trichocarpa Nisqually-1 sequence. Genome version assembly was Phytozome annotation v2.2. From the left to the right, P. deltoides female 73028–62 genetic map (in white), P. trichocarpa Nisqually-1 physical map with position of genome anchored markers (in black), and P. trichocarpa 101–74 male genetic map (in white). Scaffolds were numbered according to the v2.2 genome version. Additionally, extra scaffold (>19) containing markers mapped on the genetic maps were also shown. The length of bars is proportional to the map distance in cM or to sequence length in bp. Marker names are explained in Material and Methods. Markers in bolds are anchoring markers. Markers in bold and underlined are QTL flanking markers used for the projection of QTL confidence intervals on the physical map. QTLs were represented by vertical lines with horizontal small lines indicating start and stop of the confidence intervals and position of the LOD peak. Trait names were explained in Material and Methods.
