Inheritance of Germinative Energy and Germinative Capacity in Douglas-Fir

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, 2 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
