Forest genetics is the study of hereditary variation in trees. Tree improvement is the application of forest genetics to field practice. Tree improvement work is accomplished by testing tree family selections and determining which will grow best when planted on certain sites or in specific geographic locations. Tree improvement focuses on a few key traits: volume yield, resistance to diseases (i.e. fusiform rust), branch angle, and form.
