Most traits showed very low levels of genotype × site interaction. Estimated age–age genetic correlations for growth traits were strong at both the family (0.97) and provenance (0.99) levels. Relationships among traits (additive genetic correlation estimates) were favourable, with strong and positive estimates between growth traits (0.84 to 0.98), moderate and positive values between growth and wood-quality traits (0.32 to 0.68), moderate and positive between KPY and MoE (0.64), and high and positive between DEN and MoE (0.82). However, negative (but favourable) correlations were detected between MfA and all other evaluated traits (−0.31 to −0.96). The genetic correlation between the same trait expressed on two different sites, at family level, ranged from 0.24 to 0.42 for growth traits, and from 0.29 to 0.53 for wood traits. Therefore simultaneous genetic improvement of growth and wood property traits in CCV for the target environment in south-east Queensland should be possible, given the moderate to high estimates of heritability and favourable correlations amongst all traits studied, unless genotype × site interactions are greater than was evident.]]> Thu 20 Jun 2019 17:03:23 AEST ]]> Screening Corymbia populations for resistance to Puccinia psidii http://research.usc.edu.au/vital/access/manager/Repository/usc:10572 Thu 20 Jun 2019 16:25:32 AEST ]]> Two sympatric spotted gum species are molecularly homogeneous http://research.usc.edu.au/vital/access/manager/Repository/usc:6027 Thu 20 Jun 2019 16:13:01 AEST ]]> Local dispersion and damage of Corymbia citriodora subsp. variegata (Myrtaceae) regrowth by eriophyid mites (Acari: Eriophyoidea) http://research.usc.edu.au/vital/access/manager/Repository/usc:8186 Thu 20 Jun 2019 15:28:11 AEST ]]> Controlled Pollination Methods for Creating Corymbia Hybrids http://research.usc.edu.au/vital/access/manager/Repository/usc:6559 41% over the conventional and OSP methods, resulting in up to five-fold increases in operator productivity. However, the AIP Y treatment also had the highest C. torelliana contamination levels (9.3–13.2%). The use of exclusion bags with the AIP method had minimal effect on contamination rates, indicating a high proportion of selfpollen contamination. Contamination rates varied between maternal parents, suggesting variation in selfcompatibility for C. torelliana individuals. AIP using semi-ripe green buds was not effective at reducing selfing and had low operator productivity. The AIP method is suitable for use in a large-scale hybrid breeding program for C. torelliana. When self-pollination effects are managed, it could greatly reduce the costs associated with the production of seed of elite family crosses for commercial forestry deployment.]]> Thu 20 Jun 2019 15:26:15 AEST ]]> Variability in aggressiveness of Quambalaria pitereka isolates http://research.usc.edu.au/vital/access/manager/Repository/usc:18271 Fri 08 Jan 2016 09:53:11 AEST ]]>
