Plant deliverance in 2022/2023 categorized as improved/unimproved
In the following graphs we present deliverance of plants to the forestry categorized as improved and unimproved material. The purpose of this partition is to compare the use of material that has been genetically improved, typically as part of a forest tree breeding program, with the use of material not subject to genetic improvement. We have defined improved material as plants from seeds classified as "qualified" or "tested" according to the OECD classification (table 1 in the chapter "Seed Production per OECD Category"). Unimproved is here defined as any other material than improved. Not all countries have data for all species. For Fagus sylvativca there is no data reported during this period.

Genetically improved Norwegian oak seeds
The Research Council of Norway has provided funding to the IPN project "Genetically improved oak seed" for the period 2025 - 2028. The Norwegian Forest Seed Center is the project owner. Partners and collaborators are Norgesplanter AS, UCPH, SLU, Skogforsk, Skogselskapet i Østfold, Skogselskapet i Buskerud og Telemark, Glommen Mjøsen Skog and AT-Skog. NIBIO is the primary R&D provider.
The objective is to establish seed sources in forest, seed orchards and a breeding population for summer and winter oak.
