Coastal Douglas-Fir Controlled-Crossing Guidelines

Jayawickrama, K. J. S., Miller, L. K., and Cress, D. W. Tree Planters’ Notes 56(1):60-73. 2013.

As tree-breeding cooperatives of the Pacific Northwest begin a third cycle of breeding and testing, it is timely to describe this process for the major forest conifer species, Douglas-fir (Pseudotsuga menziesii Mirb. Franco).
