Abstract
Abies sachalinensis (F.Schmidt) Mast. is a leading species for plantation forestry in Hokkaido, Japan, and one of
main target species in the forest tree breeding. We selected superior genotypes among the population of plus trees, which were selected and tested as the achievement of 60 years of the forest tree breeding program in Japan. The selection was done with the data of growth traits and wood properties obtained from progeny trials, concerning four selection areas dividing the Hokkaido Breeding Region. In each selection area, approximately 30 genotypes have been selected to establish new seed orchards for the selection area. The selected genotypes will be used for the improvement of current seed orchards, the establishment of new seed orchards, and as parents to construct new breeding populations.
