Reciprocal recurrent selection (RRS) scheme evaluated in this study. The legends on the bottom and top indicate the cycle and the time (in years) of each phase in the breeding pipeline, respectively. The program started with the evaluation of pure-species progenies in pure-progeny trials, where the best trees were selected for intercrossing. The resulting hybrids were evaluated in hybrid-progeny trials, which were used to select the best pure-species parents based on their GHA. The selected parents of each species were recombined to form the population of the next cycle. Then, the process repeats for each cycle of RRS

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...

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...
