Quantitative Trait Loci for the first three PCs, derived from 29 traits in the F_2:3 maize families (PB260xPB266) in two environments.

a QTL position in cM from the top of the chromosome b molecular markers flanking the support interval estimated at a LOD fall of -2.00 c Additive effect = (phenotypic mean of the PB260 allele genotypes—phenotypic mean of the PB266 allele genotypes) / 2 [79]; negative values indicate that the PB266 allele increased trait additive value d Gene action: A—additive if |dominant effect/additive effect| < 0.2; PD—partial dominance 0.2 < |d/a| < 0.8, D—dominance 0.8 < |d/a| < 1.2; OD—overdominance |d/a| > 1.2 e Percent explained phenotypic variance.
