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.
Controlled pollination is an essential element in forest tree breeding. Although the concept is simple, the process requires multiple steps, which must be done correctly to obtain successful crosses. 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).
