2009) and genetic evaluation methods have all contributed to progress in eucalypt breeding. It has been recognized that strict adherence to breeding within a sequence of discrete generations is less efficient that a rolling-front approach. Best Linear Unbiased Prediction methods are used to predict and rank breeding values across multiple generations enabling choice of optimum crossing patterns as new selections reach sexual maturity and breeding values are revised (Borralho and Dutkowski 1998).

New areas for planting would become available in, for example, SE USA (Kline and Coleman), southern Europe, Latin America and China (Xu et al. 2008), where climates and soils are otherwise suitable, if the ability of eucalypts to survive sudden cold snaps associated with advective airflows from colder regions could be increased (Eldridge et al. 1993). The limited ability of all eucalypt species to survive such cold snaps in the absence of prior low night temperatures that enable the development of cold-hardening (Harwood 1981), limits their current planting domain.
