Stability of genetic effects across clonal and seedling populations of Eucalyptus globulus with common parentage

► Genetically related clones and seedlings of Eucalyptus globulus were compared. ► Clones had less disease damage and changed to adult foliage earlier than seedlings. ► Clones showed 7% less diameter growth at harvest age than seedlings. ► Propagule type did not markedly affect genetic variance or breeding value estimates. ► No clear need emerged to match testing and deployment systems by propagule type.
