Abstract
In the West foresters have had considerable difficulty in reforesting south-facing slopes. We considered this problem when we selected plus-trees for the first Douglas-fir seed orchard in Region 6. We were, however, faced with the need to answer such questions as these: (1) Should we try to produce seed inherently suited for south slopes? (2) If so, should we strive to get seed primarily of high germinative energy, or is high germinative capacity an adequate indication of suitability? Before we can select for either of these traits we need to know how they are inherited. As part of a progeny test, therefore, we checked germinative energy and germinative capacity for the seeds from several control-pollinated full-sib Douglas-fir progenies.
