I was at a meeting with WP Norway Spruce provenances and breeding in northern Poland 3-5 May. I made a
link on my web for the meeting at
http://www-genfys.slu.se/staff/dagl/Meetings/Poland07/Poland07.htm
Much of the talks were about the international IUFRO64/68 (comprising 1100 seed samples from most of the
distribution of the species) and Peter Krutzsch name was mentioned in many of the presentations, and some of
his analyses have been important contributions to the development of the series. I felt compelled to promise at
the conference dinner to carry on a greetings to Peter, so he gets a printed copy of this. Much of the initiative
came from Langlet and Sweden.
Our University closed down the provenance research in Garpenberg 1995, and if it was moved somewhere it
was to an Uppsala Department or Dalarna högskola or the field organization of SLU (formally the last is right).
SLU (or whatever was before) established and made early reports about three trials with IUFRO 64/68, now
things have happened and parts of the trials have been destroyed, even a careful documentation about why and
a quantification and analysis of provenance dependence. But no-one feel responsible.
For a review of the value of provenance trials in general I refer to a review of the value of provenances at

I said at the meeting that to meet global warming we need to test genetic materials more extended to test-sites
which are cooler than we would test them today.
I develop the thought somewhat at
http://www-genfys.slu.se/staff/dagl/Foradlrevision07/ToOtherDelp/TestSitesDag.mht
but have not still arrived at something well-phrased and logic.
Thus e.g. South Sweden should test materials regarded as suitable in northern Poland today. Thus e.g. the half
sibs mentioned below could be tested in southern Sweden also. I am aware of that much spruce has been
brought in from the continental Europe in southern Sweden, so the example may not be the best and I have not
thought how the thought should be implemented.
We visited a stand close to the Lithuanian border in the Goldap forest district. It looked very nice (Fig 1). Peter
Krutzch has chosen this stand for seed harvest and export to Sweden. In 2007 considerable cone amounts were
harvested by tree climbing and considerable amounts of seeds were exported to Sweden. Recently plus
trees (15) had been selected in the stand and open pollinated progeny collected.
Are the Ekebo people aware of this recent activities? Can they be included in the breeding work as refreshment
of the most southern breeding populations? Sweden already have a rather large collection of plus trees directly
selected as well as plus trees selected in imported stands from south of Sweden, the breeding populations of
south Sweden are likely to contain some alien genes which were south of Sweden 150 years ago, and Sweden
may already have enough breeding material for spruce in south Sweden, but Sweden should be open for
discussion when new options arise and in the light of that it is now a safe prediction that south Sweden will warm
up.
The three Swedish trials IUFRO 64/68 are managed by “Enheten för skoglig fältforskning” SLU. I find the
following information at
http://www.esf.slu.se/ShowPage.cfm?OrgenhetSida_ID=5863
There is a database – Silva boreal and a Nordic database: Noltfox. In the information below are the latest
publications I am aware of. For a new international compilation, the starting point (and probably end-point) could
be these publications. Bengt Persson is still active and the one who may know most about where old registers
are.
