Family mean height with 95% confidence intervals (bars with whiskers) and estimated probability of spike knots (black dots) in two parallel Scots pine open-progeny trials Daugmale and Norupe located in central Latvia at the age of 12 (a) and 16 (b) years before and after systematic thinning, respectively

Productive Scots pine (Pinus sylvestris L.) stands in the Baltic region ensure high-quality sawlogs for the timber market and contribute to carbon sequestration. Spike knots are serious stem defects, which reduce the proportion of valuable timber; therefore, the extent of genetic control of their occurrence and relationship with other traits must b...

Resin defects can substantially decrease timber value in Pinus radiata, a commercial forest plantation species known for its good machinability. Tree breeding is a common approach to improve economic viability and product quality in commercial forestry. This study evaluated resin canal features in a P. radiata breeding population at two sites. Phen...
The study investigates the long-term impact of Lophodermium needle cast on open-pollinated Scots pine progenies in Latvia. A significant impact of cumulative needle cast damage on growth and survival was found. Notably, 51% of trees experienced severe damage after the 4th growing season. Genetic factors played a role in survival at 12 years. Height...
Key message:Eucalyptusbreeding can benefit from strategies that capture dominance effects, as shown by the improvement in mean annual increment of wood volume across cycles of RRS. Abstract: There is no empirical validation of reciprocal recurrent selection (RRS) in Eucalyptus breeding. Our study helps to fill this gap by quantifying the realized r...
