Genetics is the main basic science providing theoretical basis for tree breeding. The discipline of genetics has been subdivided into several branches, such as molecular, population, and ecological genetics. Molecular genetics is now mainly within biotechnology project, but the borders are rather diffuse between adjacent branches.
The project is a conglomerate of several investigations. Therefore, various aims are given. What kind of adaptation to climate do the trees have, and are they able to adapt to the predicted climate change? How large is genetic variation in adaptive and commercially important traits, and how well is the genetic system able to maintain it? How to utilize the natural defence mechanisms against pests and diseases in tree breeding. What are the specific features of timber line populations? How does the genetic structure of broad leaved species differ from that of conifers?
The approach is predominantly empirical. Old provenance trials and other experimental cultivations are extremely valuable to this project. Short time experiments in manipulated environments and computer simulations are also applied. The work is performed to large extent at research stations of Punkaharju and Kolari.
