Spatial optimization of genetic thinning in seed orchards
Original language description
Key message We provide a mathematical model to determine which trees should be ruled out from the grid to promote random mating in seed orchards under genetic thinning. Context Genetic thinning (roguing) is a common practice in forest tree breeding to remove inferior genotypes in seed orchards, thus boosting the genetic worth of the seed crop. Aims To develop a general methodology for spatial optimization of genetic thinning. It should promote random mating and consider any existing seed orchard layout. Methods The model is based on the Optimum-Neighborhood Allocation algorithm (Chaloupkova et al., Forests 10:1-6, 2019). The algorithm s efficiency was evaluated using computer simulation. A fully randomized scheme was used as a reference. In addition, the study provides a demonstration on an actual seed orchard. Results Simulations confirm the method s efficiency in promoting random mating compared to the fully randomized allocation across a wide range of selection intensities. We suggest Linear Deplo
