Douglas-fir breeding in Saxony
1999
Braun, H.
Due to its high productivity as well as good ecological and silvicultural characteristics, Douglas-fir plays a special role among the introduced species in Germany. A decisive factor in successful stand establishment is the genetic suitability of the plants for the specific plantation site. Therefore, in Graupa the investigations done were focused on provenance research as well as on studies of locally selected stands and on the supply of tree types from hybrid breeding. Results are presented on (1) progeny experiments of 1982 to 1983 based on the seed collection in older stands, and (2) hybrid breeding beginning in the 1960s. Progenies from interspecific hybridisation combine highly heterotic rate of growth and high resistance to frost, better than pure Douglas-fir land races.
