  1. aQTLs are named using the “multi”, indicating that were detected using MT-MIM, followed by their genomic position in bin
  2. bcM and Mbp indicate the marker position in centiMorgans and in mega base pairs at maximum LOD value
  3. cFlanking markers are based on −1.5 LOD support interval
  4. dEffect measured as standard deviation from the progeny mean: Positive values indicate that L3 carries the allele for an increase in the trait, and negative values indicate that L22 contributes the allele for an increase in the trait. Effect significance based on p-values estimated via score statistics resampling (+ p < 0.1, *p < 0.05, **p < 0.01, ***p < 0.001)
  5. eR2: Ratio of the genotypic variance of the QTL effect to the phenotypic variance, times 100
  6. fR2 T: genotypic variance of the full model (including epistasis shown in Table 4)
