provenances descending from seed sources originating from natural distribution area Selection of provenances descending from seed stands established in Germany Selection of intra-specific progenies descending from controlled crosses between and among the varieties Current breeding programmes Slide 11 Staatsbetrieb Sachsenforst Author: Heino Wolf & Doris Krabel 11 Department: Forest Genetics and Tree Breeding Regions with comparable site conditions (geology, soil, climate, altitude) called Provenance area Recommendations related to the use of Douglas-fir forest reproductive material based on Provenance areas Breeding zones defined for Douglas-fir Slide 12 Staatsbetrieb Sachsenforst Author: Heino Wolf & Doris Krabel 12 Department: Forest Genetics and Tree Breeding Slide 13 Staatsbetrieb Sachsenforst Author: Heino Wolf & Doris Krabel 13 Department: Forest Genetics and Tree Breeding Around 2.300 stands in the category selected Regional distribution quite inhomogenous Stands mainly pure, homogenous and even-aged Hybrid-breeding populations About 850 clones of coastal and interior variety 104 full-sib-F1-families 3 full-sib-F2-families Breeding populations Slide 14 Staatsbetrieb Sachsenforst Author: Heino Wolf & Doris Krabel 14 Department: Forest Genetics and Tree Breeding Provenance which contribute the most to the Douglas-fir breeding population Coastal variety in regions with climate influenced by the Atlantic Interior variety in regions with climate influenced by the continent Slide 15 Staatsbetrieb Sachsenforst Author: Heino Wolf & Doris Krabel 15 Department: Forest

Heino Wolf & Doris Krabel 19 Department: Forest Genetics and Tree Breeding Most investigated tree species in Germany For most states recommendations for the use Douglas-fir provenances do exist Limited number of seed stands, seed orchards, F1- progenies is already tested and some basic material is already approved for the procurement of FRM, category tested Still lack of knowledge regarding the origin of local artificial populations Major results Slide 20 Staatsbetrieb Sachsenforst Author: Heino Wolf & Doris Krabel 20 Department: Forest Genetics and Tree Breeding Coastal variety: high yield, different quality traits, low resistance against frost and Phaeocryptopus needle cast, high resistance against Rhabdocline needle cast Interior variety: low yield, different quality traits, high resistance against frost and Phaaeocryptopus needle cast, low resistance against Rhabdocline needle cast Big variation at provenance level within the variety Hybrids: in several progenies high yield and frost resistance could be combined together with average branchiness and needle cast resistance Results on genetic variability studies Slide 21 Staatsbetrieb Sachsenforst Author: Heino Wolf
