6. Quantitative Genetics and Genomic Selection of Scots pine
Sammanfattning : The final objective of tree improvement programs is to increase the frequency of favourable alleles in a population, for the traits of interest within the breeding programs. To achieve this, it is crucial to decompose the phenotypic variance accurately into its genetic and environmental components in order to obtain a precise estimation of genetic parameters and to increase genetic gains.

7. Growth of genetically improved stands of Norway spruce, Scots pine and loblolly pine
Sammanfattning : Genetically improved material of Norway spruce (Picea abies (L.) Karst.), Scots pine (Pinus sylvestris L.) and loblolly pine (Pinus taeda L. LÄS MER
8. Quantitative genetics of wood quality traits in Scots pine
Sammanfattning : Wood quality of commercial tree species is important for many wood processingindustries and thus should be considered for inclusion in forest tree improvementprograms. This thesis evaluated the suitability of various proxy methods for rapid andnon-destructive assessment of wood quality traits on standing trees of Scots pine and thepotential for genetic improvement of different wood quality traits through recurrentselective breeding.

9. Volatiles of Conifer Seedlings : Compositions and Resistance Markers
Sammanfattning : Pine weevils cause major damage to newly planted conifer seedlings in reforestation areas. However, recent findings indicate that small (“mini”) seedlings, planted at the age of 7-10 weeks, are gnawed less by pine weevils than the larger, conventionally planted seedlings. LÄS MER
10. Above Ground Durability of Swedish Softwood
Sammanfattning : This thesis describes aspects of durability of Swedish softwood in above ground applications. The thesis consists of a summary of nine papers, which all aim to explain the existing variation in above ground microbial durability and moisture sensitivity of Norway spruce (Picea abies) and Scots pine (Pinus sylvestris).
