1. The “ Best” Seed Sources for Christmas Trees Chal Landgren OSU Extension A quick review of heritability A practical look at selecting the best of what’s available. Remember, there is no “Perfect Source”- it always depends on availability, your definition of perfection and so on …. Review research and collections in Turkey
39. When planting an unproven source, remember the following- American Christmas Tree Journal . 1999. Vol. 43(2):4-11. by John Frampton and Craig McKinley Table 1. Comparison of desirable traits for an idealized natural-grown low density European and a medium to high density sheared American Christmas tree . Trait Europe USA Growth Slow Fast Crown Density Low to Medium Medium to High Internodal Branches Many Many Crown Diameter Small Large Branch Angle Slightly Above Horizontal Preferences Vary
Much has changed in the last 50 years. Where will we be in another 50? Changes from wild harvest on unproductive sites to plantation growing on productive sites- From Shelton to Silverton

Id. Some traits we like and there is reason to suspect these are heritable How can you deliver trees that consistently have those traits Clone Slide-NF rooted cutting not very reliable Family-Controlled cross- Hostelter orchard (brothers and sisters) Family-seed Slide of Stand- In the area Slide of Seed Zones- Provenance Any ole fir- can not get any better than the nursery.
Genetics may not be the correct word here. Point being that TI adds value in all these areas.
Hoping to give this talk- Finally had to help organize and invite myself How did we get to where we are- summarize past trials and critique- Explain Hand-Outs Items beyond genetics-Maybe more influential
Dk sources tend to be slow growing,tree buyers not too interested in needle form
Exmple with Hupp and MCniels
Hope to have all the files on extension web site this summer
Trial in 1999- 8 sources 3 TK; 5 Nord- 3 TK fir were clearly the top sources- 225 (Kokez) Trial in 2004- 21 sources 4 TK, 17 Nord, Top 6 last yr. 4 were TK- 219 (Akyazi)
COLLABORATIVE FIR GERMPLASM EVAL. PORJECT 6 REGIONS- CONN, DK, MI, PNW, PA , NC REDUCED CONING, PHOTOPH RESISTANCE, 2 CLIMBERS EACH Day, 4-5 cars+ drivers+ ministry foresters

4 million pop. In city Ataturk is the Washington, Lincoln and Jefferson- picture is everywhere, Penal code is Italians Civil code is Swiss, Modified Latin analphabet replaced Arabic literacy rows fro 10 % to over 79% in 2 yrs.
Spice and dye saffron is from here. Camel enclosure on the /silk rd- roman- ottoman walls here were 4” thick
Tea served even in logging camp
Looks like PNW
