Summary of significant polymorphisms from genome-wide and candidate gene-based association studies.

aThe favorable allele for αT is underlined. Alleles 7 and 0 indicate a 7-bp and 0-bp insertion at the InDel7 locus, respectively. Alleles 118 and 0 indicate a 118-bp and 0-bp insertion at the InDel118 locus, respectively. For InDel7, a third allele (allele4, 4-bp insertion) was only present in four high-oil lines.bThe SNP code from Illumina MaizeSNP50 BeadChip, the corresponding name and the source sequences of the SNP can be obtained from the Illumina website (Illumina). Both the P values and the phenotypic variations explained (R2) were from a mixed linear model controlling for population structure and individual relatedness. αT, α-tocopherol; γT, γ-tocopherol; TT, total tocopherol.
