1. Game of crops : genetic composition and adaptation of seed orchard crops
Abstract : Orchard populations are artificial and intensively managed populations of elite, best-performing trees that are established for mass production of genetically improved seeds. Seed orchards connect cycles of selection, breeding, and testing of plus-trees with the deployment of the improved seeds at the operational plantations. READ MORE

2. Population management of cone and seed insects in spruce seed orchards
Abstract : Seed orchards have been established in order to produce high quality seeds for reforestation and forestation. However, seed production in spruce (Picea abies (L.) Karst.) seed orchards is severely hampered by cone- and seed-feeding insects. READ MORE

3. Genetic diversity and differentiation in natural and managed stands of Norway spruce (Picea abies)
Abstract : Being one of Sweden’s most important tree species, both as a keystone species and for the forest industry, it is important that we keep our stands of Norway spruce (Picea abies (L.) Karst.) as healthy as possible. READ MORE

4. Spatiotemporal patterns of genetic variation for growth and fertility in Scots pine
Abstract : Genetic testing plays an important role in tree breeding. Understanding basic genetic parameters for growth and fertility is a prerequisite for developing a successful breeding strategy to balance between short- and long-term gains. It is both impractical and inefficient to wait until trials are several decades old to make selection decisions. READ MORE
