  • The QTL position for each NIL is reported by the markers that flank the LOD peak, with the closer marker underlined. The peak LOD score under a hypothesis that allows both additive (a) and dominance (d) effects is given and those effect estimates are listed as trait unit contributions. Gene action is inferred from d/a: recessive (R) is for d/a < −0.67, recessive to additive (RA) for −0.67 > d/a > −0.33, additive (A) for −0.33 > d/a > 0.33, dominant to additive (DA) for 0.33 > d/a > 0.67, and dominant (D) for d/a > 0.67. The parental source of the allele, percentage of the phenotypic variance explained, and the percentage mean subspecies difference (PMSSD) are also listed for each QTL. PMSSD = 100 × [2a/MSSD]. The threshold LOD values for the two studies were 1.99 and 1.90, respectively.
