Abstract

Eucalyptus globulus is the main eucalypt species grown in Australian plantations. The focus
on seedling deployment systems, coupled with exploitation of large, open-pollinated base
populations for breeding purposes over the last two decades, has required a detailed
understanding of the reproductive biology of this species. We review our research on the
reproductive biology of E. globulus, with a focus on it’s breeding system and advances made
in seed production systems. While most improved seed is still obtained from open-pollinated
seedling or grafted seed orchards, the development of the one-stop/single-visit pollination
procedure has revolutionised the breeding and deployment of this species. The reduced
costs of controlled pollination has meant full pedigree-control can now be maintained in large
advanced generation breeding populations and E. globulus is one of the few eucalypt
species where large-scale production of manually pollinated seed for family forestry is being
undertaken.
