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

Another Strategy
Every tree order will include 10 trees from the worse source we know!!!!

Genetics- is only part of a successful operation
Site - #1
Nursery/Stock Type/Storage - #2
Culture/skill - #3
Genetics- adds value
Weed Control- (improved trees die too)
Pests

Some General Lessons for Noble
Danish sources are slow and blue
Cascade sources have done poorly
Riley-Fanno area have been good
Edwards Butte ‘promising’
![Page 25: Best sources ts 2011](https://reader036.vdocuments.site/reader036/viewer/2022070301/5464b677af795950608b5d9d/html5/thumbnails/25.jpg)
Nordmann fir-What’s Available?
Nordmann fir Nordmann fir Ambrolauri Ambrolauri-Tlugi Borjomi (Russia)
Ambrolauri- Tends to be slow growing, but later bud break
The “Turkish” Nordmann have generally been poor for quality.
Yayla means near timberline- avoid.

When planting an unproven source, remember the following-
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 AngleSlightly Above

Reality CheckMost plantings are still seed zone or
provenance collections, so there will be wide variation in the planted field.
The “system” relies heavily on the honesty of all parties seed collector through nursery.
Never ask “do have source XYZ?” Ask--- “What do you have in species ABC?”
With developing orchard capacity more improved sources available.
![Page 41: Best sources ts 2011](https://reader036.vdocuments.site/reader036/viewer/2022070301/5464b677af795950608b5d9d/html5/thumbnails/41.jpg)
Some “issues” to think aboutDo you know what consumers want now
from your trees?
How do we know what consumers will want in 20 years? Breeding trees takes time.
We may want to offer a wider range of sources with bio’s on each so growers can pick according to their customer needs

Growing Nordmann & Turkish Fir
•Slow for first 2 years
•Only one growth flush/season
•Some sources have significant in-pointing branches and/or up- turned whorls.
•Buds clustered near outer 30% of branch- avoid “fat” trees early
