paper describes the establishment of provenance seedling seed
orchards of three spotted gums and cadaga (all species of
Corymbia ex Eucalyptus). It also discusses the limitations of
growing the spotted gums as pure species including: lack of mass
flowering, susceptibility to a fungal shoot blight and low
amenability to vegetative propagation. These limitations,
together with observation of putative natural hybrids of the
spotted gums with cadaga, and the early promise of manipulated
hybrids, led to an intensive breeding and testing program. Many
hybrid families have significant advantages in growth and
tolerance to disease, insects and frost,
