Background Increasing our understanding of the genetic architecture of complex traits,
through analyses of genotype-phenotype associations and of the genes/polymorphisms
accounting for trait variation, is crucial, to improve the integration of molecular markers into
forest tree breeding. In this study, two full-sib families and one breeding population of
maritime pine were used to identify quantitative trait loci (QTLs) for height growth and stem
straightness, through linkage analysis (LA) and linkage disequilibrium (LD) mapping …

of the F2 mapping population. The LOD score patterns for total height (blue) and stem
straightness (orange) over the 12 linkage groups of maritime pine are represented. The
location of the QTLs (p < 0.05 at the genome wide level) is indicated by vertical dotted lines. …
