Clone-site Interaction of Eastern Cottonwood

Superior clones of eastern cottonwood (Populus deltoides Bartr.) are being sought for extensive plantations that are being established in the Lower Mississippi Valley. Site quality in this region varies from excellent on loamy soils to poor on heavy clay soils. Where there are large variations in site productivity, crop breeders have found important genotype-environment interactions. In the study reported here, clone-site interactions for cottonwood were sufficiently large to be considered in a breeding program.
