Leaf lamina shape variation among parents and progeny of the P. trichocarpa X P. deltoides pseudobackcross pedigree family 52–124. The donor parent, P. trichocarpa, has a lamina length/width ratio of ~3.0, while the recurrent parent, P. deltoides, has a lamina ratio of ~1.0. The trait exhibits additive variation, as the hybrid parent has a ratio of ~1.5. Segregating BC1 progeny span the spectrum of phenotypic varation from the hybrid to the recurrent parent with limited transgressive segregation observed
