Partial genotypic effects of SNPs significantly associated with growth and wood properties.
Trees were segregated into genotype categories and corresponding phenotypes were plotted. Error bars indicate standard deviations; the x axes represent the genotype categories and the y axes represent the traits that the SNPs are associated with: tree height, holocellulose content, α-cellulose content, lignin content and fiber length.
