  1. aThe peak position with the highest LOD of each QTL.
  2. bThe physical positions of the identified QTL according to B73 reference sequence Version 5.60 [38].
  3. c Additive effect of the identified QTL: a positive value indicates that the alleles from H127R and By804 increases RPR, and a negative value indicates that the alleles from Chang7-2 and B73 increase RPR.
  4. dPercentage of phenotypic variation explained by additive effects of the identified QTL.
  5. eTotal percentage of phenotypic variation explained by all QTL computed by MIM.
