Locations on linkage groups (LGs) of the BH and ES genetic maps, and contributions of the putative QTLs that control sugar- and acid-related traits, which were identified in at least two of three successive years (2011, 2012 and 2013). The locus is the marker showing the strongest association with the trait. The location of markers is given in cM, quoted from the top of each linkage group. R ² represents the individual contribution of one QTL to the variation in a trait, and LOD is the logarithm of the odds ratio. SSC and β ratio represent soluble solids content and the tartaric acid-to-malic acid ratio, respectively. Traits in bold had QTLs detected in two years.
