QTL with symbols ‘#’ and ‘&’ are those stably detected in both the NN09 and SY10 environments in the Ce258 and ZGX1 backgrounds, respectively. Loci that passed the main-effect QTL confirmation test (See step 3 in the Materials and Methods) in at least one background are shown in bold.
Underlined markers are those closer to putative QTL.
Underlined numbers are the parameters of the QTL detected under the sub-threshold of 1.2 ≤ LOD ≤ the threshold estimated by permutation test as described in the Materials and Methods.
Additive effects resulting from the substitution of ZGX1 or Ce258 alleles by IR75862 alleles
Numbers in brackets are reference codes, as listed in the reference section.
