Each entry lists the chromosome, chromosome position in bp within brackets, LOD score, and P value for an identified QTL. Markers with P ≤ 0.2 are listed.
a
Results of a pairwise scan of two-QTL interactions among single-environment and GEI QTL.
b
Results of a targeted scan for two-QTL interactions where one locus is constrained to be a large-effect QTL.
c
Results of a targeted scan for three-QTL interactions.
