The wood in our forest trees has a complex struc- ture where the different components have their own characteristics. Forest products get an increasing importance and can be used for new type of prod- ucts as we learn better how to use the different com- ponents. At the same time are the wood and fibre traits strongly genetically inherited and they are thus suitable for including in breeding programs for forest trees.

Anders Fries 1150 My research is largely focused on the field of genetics of wood and fibre traits in Scots pine (Pinus sylvestris) and lodgepole pine (Pinus contorta), and techniques for measuring and evaluating those traits.The aims are: i) to evaluate techniques and designs for taking wood samples in progeny testing, ii) to develop differ- ent techniques for analyzing wood and fibre traits, e.g. acoustic velocity, X-ray and Kajaani Fiber analyses, and to apply those techniques to progeny testing, iii) to evaluate progeny tests for growth and wood and fibre traits, and their interrelationships and iv) to determine the distribution of wood and fibre traits and their genetic parameters in the stem from ground level to the top and pith to bark, and also evaluate genetic parameters on whole tree level.

Two ongoing projects make large scale genetic surveys of Scots pine and lodgepole pines. Here a high number of traits, such as growth capacity, field performance, phenology, wood and fibre traits and pulp yield, are measured and their inheritance and genetic relationships are evaluated. For the wood and fibre traits are SilviScan analyzes utilized and for wood stiffness we measure the acoustic velocity of the wood.
Another project makes a directed investigation of the rela- tionship between wood stiffness in lodgepole pines in a clonal field test. Clonal field tests are very well suited for analyzes of wood quality traits.The availability of clonal copies increase the precision in estimates and makes destructive tests possible without losing the clone.

This clone has extremely low stiffness, as also revealed by analysis of microfibril angle with SilviScan instrument.Increment core10-mm increment core for SilviScan-analysis. The core is sampled in a Scots pine progeny test.

One of my projects is a species-genotype-environment study. This evaluates the effect of using exotic species. A transcon- tinental field test series with lodgepole pine grown as exotic species in Sweden and Scots pine as exotic species in Canada is evaluated (see the first photo).
The aims are to evaluate the potential risks by using an exotic species and also to analyze the large superiority in production of the exot lodgepole pine over Scots pine in Sweden.

I take also part in a project working with association mapping at the department. My part in it is to deal with the work in field (collection of material, measurements etc.).
