✦ Synopsis
Application. Large changes in family composition during nursery production can lead to reductions in genetic diversity and unpredictable genetic gains from tree improvement programs. Douglas-fir families were shown to differ in their ability to produce plantable seedlings under operational nursery conditions. The resulting changes in family composition, however, were not great enough to justify the increased costs of segregating families within the nursery in order to better control the composition of outplanting stock.
