Quantitative Trait Loci (QTL) for apple fruit size. Physical positions (Mb) of the Quantitative Trait Loci (QTLs) detected on the parental 'Royal Gala' genetic map (RG, blue) and on the consensus 'Starkrimson' × 'Granny Smith' (STK × GS, red). QTLs are represented by boxes, in which length represents the LOD-1 confidence interval and extended lines represent the LOD-2 confidence interval. Mapped candidate genes ARF6 and ARF106 are in bold underlined.
