Genetics of wood and fibre traits

One branch of my research is on the genetics of wood and fibre traits in Scots pine, and techniques for measuring and evaluating those traits. The aims are: i) to evaluate techniques and designs for taking wood samples in progeny tests, ii) to evaluate progeny tests for wood and fibre traits, and their relation to growth, iii) to determine the distribution of wood and fibre traits in the stem from ground level to the top, and connect genetic parameters to them for the whole tree, and iv) to develop different techniques for analyzing wood and fibre traits, e.g. X-ray and Kajaani Fiber analyses, and to apply them to progeny testing.

Studies in seed orchard

Västerhus seed orchard. The most genetically advanced Scots pine seed orchard is studied for pollen contamination etcetera

Seed orchards are production units for seeds of elite genetic and physiological clones. Production can however be improved, especially with new molecular fingerprinting techniques. I work in a group which studies the following aspects of seed orchards: i) physical development (growth, flowering etc.); ii) the pollination pattern in orchards using molecular techniques, (dominating clones in the pollen cloud, reproductive success, contaminating unselected pollen from surrounding natural stands etc.); iii) the potential of selective seed harvest from individual clones for ingto reach genetic top quality, and iv) the development of a technique for determining parental origins of plants arising from open pollination in seed orchards by molecular fingerprinting, so-called breeding without breeding, as an alternative to progeny testing based on costly controlled crossesparental origin of - as an alternative to progeny testing based on costly controlled crosses.

QTLs for wood and fibre traits

Measurement of wood density with X-ray

I work in a group which aims to identify QTLs (Quantitative Trait Loci) for genes that regulate, among others, the following wood and fibre traits in Scots pine:

wood density, its distribution between earlywood and latewood, and the relation to ring width,
dimensions of wood fibres
microfibril angle

Other research areas:
properties of the heartwood and sapwood of Scots pine, e.g. the amount of heartwood and its content of wood extractives, progeny testing in general, gene resources of larch for Sweden, and genetic parameters for production traits.
