^aThe peak position with the highest LOD of each QTL.
^bThe physical positions of the identified QTL according to B73 reference sequence Version 5.60 [38].
^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.
^dPercentage of phenotypic variation explained by additive effects of the identified QTL.
^eTotal percentage of phenotypic variation explained by all QTL computed by MIM.
