International audience; Despite recent developments in molecular markers, most forest tree breeding programmes do not use them routinely. One way to integrate markers would be to use them for pedigree reconstruction after a simplified mating design t

Optimal contribution selection (OCS) is a mathematical optimization problem that aims to maximize the total benefit from selecting a group of individuals under a constraint on genetic diversity. We are specifically focused on OCS as applied to forest

Like other outcrossing species, Scots pine (Pinus sylvestris L.) is thought to carry a “genetic load” of deleterious recessive alleles. When these alleles occur as homozygotes in inbred progeny, their expression can give rise to “inbreeding dep

This final paper of the series discusses implications of various aspects of using clones in forestry. Benefits from using clones are considerable. A large benefit arises from the ability to deploy genetic gain much sooner than is possible through con

Tree health and growth rate must both be considered in Scots pine breeding for harsh areas such as northern Sweden. Univariate (UV) and multivariate (MV) multi-environment trial (MET) analyses of tree vitality (a measure of tree health) and height (a

Phenology can have a profound effect on growth and climatic adaptability of long-lived, northern tree species such as Scots pine ( L.), where the onset of growth in the spring is triggered mainly by accumulated heat, while cessation of growth is rela

Combined-variable (D2H) and exponential-ratio equations are presented for predicting stem volume of loblolly pine in the Atlantic Coastal Plain of the southeastern United States. The equations were derived using 985 stems in a replicated study with f

Possibilities for early selection of clones for future seed cone production were studied in a clonal seed orchard of Scots pine (Pinus sylvestris L.) in northern Sweden over the first 30 years following establishment. The annual data were modelled as

Genetic gains based on a genetic test using clonal replicates were compared to those based on a test using seedlings at the same gene diversity and testing effort levels using POPSIM™ Simulator. Three testing and deployment strategies targeting for

Total inside-bark volume is the most important selection criterion for productivity in tree breeding programs in the Southeastern U.S. Tree breeders typically estimate total inside-bark volume based on outside-bark diameter at breast height and total
