The genetics of cultivars are damaged. The seedlings are in much better
shape genetically. Counter argument - When one buys a cultivar, one
isn't buying genetics, one is buying phenotypic expression.*
This is an elegant analysis... we are motivated by phenotypic
expression... it is easy to eat.

Synthesis - The seed is a much smaller package and can be stored for
long periods of time. Especially when it germinates under the plant or
by squirrel, there is the feeling that the conditions are right for the
plant. Likewise, improvement of the plant is much faster even if it is
from a much less improved basis.*
what does "there is the feeling that the conditions are right for the
plant" mean?
If we value phenotypic expression, what does the rate of improvement
matter? And if value comes from phenotypic expression, how do you
characterize 'improvment'? There is a lot of subtext related to
population level genetics I'd like to hear more about. Are you
suggesting that we adjust our values to include management of population
genetics when planting exotic species?
I have taken the approach of buying in limited numbers of cultivars
while foraging for seed and cuttings to meet future needs. My initial
plantings become parent plantings as cuttings and seed come available,
and are mixed with more genetically and floristically diverse materials
as I locate free sources from both sexual and asexual propagation. One
example is I have purchased one each of 5 varieties of Corylus avellana
that are blight resistant and produce medium to large kernals. I got
them from stool propagation at $11US each. I will stool or layer them
in turn to multiply.. to approximately 15 trees of 5 varieties in my
limited zone 3 (which might shift to zone 2 as my influence on the site
increases). Blight is spreading north into my area, likely increasing
with climate change. I might include additional individuals in my less
managed hedgerows. Why should I be motivated to invest in seedling
Corylus avellana?
