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.

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 When we can evaluate the chance that we can identify the parents

Plantation with Västerhus seeds

Harvesting needles from plantation with Västerhus

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 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

Null alleles assumed to be partly present Contamination (%)51,63(+ 3,95) Selfing (%)1,30(+ 0,62) Outcrossing within seed orchad (%) 47,07(+ 4,05) Pollen contamination and self-fertilization, within Västerhus in 9 loci 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
