Research paper thumbnail of Growth, Form and Quambalaria Shoot Blight Tolerance of Spotted Gum in North-eastern New South Wales, Australia

The trial contained a wide range of genotypes, mainly of Corymbia citriodora subsp. variegata, with between one and 21 families per provenance. Genetic parameters were calculated from 23 provenances with four or more families. Provenances superior for growth included four well-represented C. citriodora subsp. variegata provenances, all from south-east Queensland, which also had a high proportion of superior families. Overall, Queensland provenances had significantly higher mean diameter and height than those from New South Wales (NSW), although there were several superior NSW families. Provenances superior for growth also displayed good straightness and relatively fine branching. Relatively low Quambalaria shoot blight damage was recorded for four Queensland provenances and one coastal ...

Research paper thumbnail of Pectin Methylesterase Genes Influence Solid Wood Properties of Eucalyptus pilularis

PME6 was primarily associated with the shrinkage and collapse of drying timber, which are phenotypic traits consistent with the role of pectin as a hydrophilic polysaccharide. PME7 was primarily associated with cellulose and pulp yield traits and had an inverse correlation with lignin content. Selection of specific alleles in these genes may be important for improving trees as sources of high-quality wood products. A heterozygote advantage was postulated for the PME7 loci and, in combination with haplotype blocks, may explain the absence of a homozygous class at all single-nucleotide polymorphisms investigated in this gene.

Provenance means and genetic parameters for growth measured at ages 3, 8 and 26 years plus stem straightness, branch angle and nodality at age 26 years are reported. Large provenance differences were apparent for all traits. The two island provenances, Cedros and Guadalupe, were significantly inferior to the mainland provenances and, due to competition effects, very few trees survived to age 26. Within the mainland provenances, the performance of Año Nuevo and Monterey was almost identical, with Cambria being less vigorous. The best performing seedlot for all traits was the local control. Differences between populations within the mainland provenances were apparent for diameter at age 26 within Año Nuevo and Cambria but not Monterey...

Association studies allow links between phenotype and genotype to be made, and are a prelude to accelerated domestication of trees by molecular breeding approaches. This study uses association genetics to identify DNA polymorphisms that correlate with solid wood properties of Eucalyptus pilularis Smith (blackbutt). We undertook extensive phenotyping of dimensional stability, growth and ...

Annulares Blakely) includes some of the most important commercial species (i.e. Eucalyptus urophylla S.T.Blake) worldwide for forestry in the subtropics and tropics. However, the taxonomic status of some species in this group is unclear and the relationship among and genetic structuring within some species is unresolved. The present study examined genetic variation at 13 microsatellite loci in E. pellita F.Muell., E. resinifera Smith and E. scias L.Johnson & K.Hill. Despite close geographical proximity and natural hybridisation in northern Queensland, E. resinifera and E. pellita remain genetically distinct as taxa. Within E. pellita, two genetic groups were clearly resolved, one from New Guinea and one from Queensland (Cape York Peninsula populations were not sampled). Geographic structuring was also evident in E. resinifera, with northern Queensland populations separating from those from Fraser Island southwards. Ecological factors and speci...
