Table 2. Summary of QTL permutation test output. Percent variance in
surveys for nsects and fungi explained by significant marker indicated
for composite interval mapping models. Positive (+) allele specifies
genotype at significant interval that results in an increase in
susceptibility. D indicates progeny are homozygous for P.
deltoides alleles and T indicates progeny are heterozygous for P.
deltoides and P. trichocarpa alleles.
