  • a The LOD curve is still rising at the terminal marker (see Figure 2).

  • QTL positions are reported by chromosome with S and L indicating cytologically defined short and long arms and C denoting centromeric, as well as by the markers on each side of the LOD peak with the closer marker underlined. The peak LOD score, additive effect estimate listed as a trait unit contribution, parental source of the allele, and percentage of the phenotypic variance explained are listed for each QTL. The threshold LOD values for the three traits were 2.64, 2.62, and 2.53, respectively.
