“…Thus pests such as Mycosphaerella leaf disease or autumn gum moth, which favour juvenile foliage, may have less impact on growth because damage is confined to early in plantation development (typically less than 3 years of age), compared to species such as eucalypt weevil that damage juvenile and adult foliage ( Table 2). While there is genetic variation in susceptibility within E. globulus to a variety of pests (Rapley, 2005;Ugalde, 2008;O'ReillyWapstra et al, 2010;Miller et al, 2011) initial studies suggest within-species physiological responsesare similar for similar levels of defoliaton (C. Borzak, unpublished).…”

“…Provenance differences in susceptibility to pests (e.g. insects - Jordan et al 2002, mammals -O'Reilly-Wapstra et al 2002Miller et al 2011), diseases (e.g. Mycosphaerella leaf disease (MLD) caused by Teratosphaeria species - Carnegie and Ades 2005) and susceptibility to wood decay have been reported in E. globulus Hamilton et al 2007).…”

“…Several approaches are being used to reduce marsupial browsing damage in plantations, including seedling protection with stockings or repellent (Miller et al 2008). However, genetic based differences in susceptibility are more persistent and there are direct and indirect (defensive chemistry) screening approaches for genetic improvement (Miller et al 2009;Miller et al 2011).…”

Initial productivity and genetic parameters of three Corymbia species in Brazil: designing a breeding strategy

et al. 2021

The survival, initial productivity and the genetic parameters of C. citriodora subsp. citriodora (CCC), C. citriodora subsp. variegata (CCV) and C. torelliana (CT) were used to develop a breeding strategy for the Corymbia species. Survival, height and diameter at breast height (DBH) data were assessed 24 and 36 months after planting and the mean annual volume increment estimated in three trials. Longitudinal DBH data analysis was applied to each trial individually, to identify the best and the poorest families at both ages. The mortality ranged from 5% in CT to 27% in CCC and the mean annual increment varied from 17.8 to 20 m3 ha-1 year-1 at 36 months after planting. The 36-month narrow-sense heritability (ha2) was high for CCV (0.69±0.17), moderate for CCC (0.41±0.11) and low for CT (0.21±0.09). The genetic parameters indicated the need for different breeding strategies, for each species. Selecting the best families while roguing the poor families allowed forward selection of CCC and CCV. It was possible to select good CT trees for hybrid breeding, however, improving the species population requires focusing on increasing the effective size and expanding the genetic variability in the CT population.
