Course abstract | |
Students learn theoretical base of forest trees improvement (breeding), become acquainted with processes and tasks of forest tree improvement, display of heritability and variation, phenotype and genotype. Students also learn the methods of tree breeding – the basis of selection, hybridization, clone, family, provenance and ecotype. They become acquainted with classification of trees and stands from the breeding perspective, as well establishing and management of seed orchards. | |
Learning outcomes and their assessment | |
Knowledge and competence in tree breeding process and its practical realization. Competence to assess results of progeny tests and evaluate genetic gain. | |
