Incorporating Genetic Information In Growth And Yield Models

In tree improvement programs, biological differences resulting from selection and breeding should be quantified in such a way that they can be incorporated into yield prediction systems. Only if this information is included in growth and yield models can genetic gain be estimated by comparing improved tree yields with woods run material for specific management regimes. In this study, we selected an individual tree model for loblolly pine and modified four relationships that reflect genetic differences, then we compared yields with woods run material. Gains and losses for the various systems are reported. Additional keywords: Genetic gain, loblolly pine, simulation
