The mean protein and oil content of the genotypes with the alternative SNP alleles, the difference in protein and oil content between the genotypes with the alternative alleles and the direction (negative or positive) of the protein vs. oil effects associated with the alleles at each locus.
^aA negative relationship indicates that the allele associated with greater protein content was associated with reduced oil content and vice versa. A positive relationship indicates that the allele associated with greater protein content was also associated with greater oil content and the alternative allele was associated with both reduced protein and oil content.
