Anders and me selected study trees and harvested
needles

• Criteria 3 ramets per clone
• Possible to study pollen spreading from rare
  clones
• Somewhat spread over the orchard
• Needles in Xiao-Rus lab

Västerhus

• We are anyway genotyping the seed orchard and its
  offspring
• There are a few mature (30 year) crosses among
  seed orchard trees (in old seed orchards,
  Domsjöänget). Johan Kroon will help us to find
  some such trees and we will check the
  possibilities to make phenotypic selection
  followed by parent determination in a situation
  where we know the parents. Not many trees. A few
  days in the summer 2008 to look at the material.

16
Mature seed orchard Domsjöänget, 25 kms from
Västerhus. These trees were crossed in the
orchard and the progeny planted in field trial.
The field trials were evaluated and the best
clones placed in Västerhus. Some of the crosses
are between Västerhus clones and exist in a 30
year old progeny-test where we collected needles
June 2008. When we can evaluate the chance that
we can identify the parents

• Trees at the progeny trial Kvarntorp with crosses
  at Domsjöänget at needle collection June 2008
• Needles are collected by cutting branches down
  with a pole with a saw (at the centre of the
  picture)

Half sib forestry

• I and Anders have applied to Kempe in coop with
  the chief silviculturist at Holmen and the seed
  manager of SSP (Lagan, Finnvid). We did not get
  money.
• We applied in Bo Rydin but they suggested no
  spring meeting
• We applied föreningen but they did not want to
  initiate something without the full board.
• We now have an application at Bo Rydin and will
  send one to föreningen
• Thus we wait till 2009 with the seeds. One
  advtage is that the pollen production dropped
  2007, but hopefully will raise again 2008.
• Harvesting 25 of area of Västerhus clonewise
• The number of seeds will be counted for each
  clone, thus the female fertility. This can be
  combined with our measurements of male fertility
• Follow these harvests through seeds, nursery to
  the field.
• Ten halfsib families are chosen for trials
• 10 field plantations around 20 hectars each with
  the 10 lots with half sibs and 3 (as comparison)
  with mixtures
• We may revise BWB to be applied to half sib
  forests, when we know the mother

Pollen contamination and self-fertilization,
within Västerhus in 9 loci
Null alleles assumed to be Null alleles assumed to be Null alleles assumed to be Null alleles assumed to be Null alleles assumed to be Null alleles assumed to be
partly present partly present
Contamination () 51,63 ( 3,95)
Selfing () 1,30 ( 0,62)
Outcrossing within seed orchad () 47,07 ( 4,05)
Standard error in parentheses
Contamination is high like in most similar
studies!! Remains a very big and unsolved problem
Selfing is low compared to similar earlier
studies, non problematic level
