1. Quantifying individual variation in reaction norms using random regression models fitted through Legendre polynomials: application in eucalyptus breeding
ABSTRACT An accurate, efficient and informative statistical method for analyses of genotype × environment (G × E) interactions is a key requirement for progress in any breeding program. Thus, the objective of this study was to quantify individual variation in reaction norms using random regression models fitted through Legendre polynomials in eucalyptus (E

2. THE USE OF GENETIC DISTANCE AND GROUPING METHODS TO PREDICT Eucalyptus Pellita F. MUELL GENITORS FOR HYBRIDIZATION
ABSTRACT The objective of this study was to use quantitative traits to estimate the genetic distance among E. pellita provenances and progenies, to inform possible hybridization strategies in a species improvement program. A provenance and progeny test with 118 progenies from seven provenances was evaluated. The following quantitative traits were measured at

3. Avaliação da resistência de progênies de Eucalyptus grandis para mancha foliar de Cylindrocladium e Kirramyces
RESUMO Durante o cultivo do eucalipto existem várias doenças que podem limitar sua produtividade, tal como as manchas foliares causadas por Cylindrocladium spp. e Kirramyces epicoccoides. Assim, este trabalho teve como objetivo avaliar a resistência de progênies de Eucalyptus grandis a estas doenças. O teste de progênie com 176 progênies e três teste

4. Do the Growing Conditions of Trees Influence the Wood Properties?
ABSTRACT Currently, there is a little and sparse information about how the growing conditions influence the spatial variation of wood along the stem. Thus, the aim of this study was to compile the knowledge from literature in a manuscript for better understanding to what extent the growing conditions influence the spatial variation of wood properties in Euca

5. Bayesian analysis of growth, stem straightness and branching quality in full-sib families of Eucalyptus globulus
ABSTRACT Eucalyptus globulus is one of the most commonly planted hardwood species for industrial use in various temperate regions around the world. The present study aimed to evaluate 62 full-sib families of E. globulus in one of the southernmost progeny trials of the species in the south of Chile. Estimates of genetic parameters for stem straightness, branc

6. Quantity, organization, and distribution of chloroplast microsatellites in all species of Eucalyptus with available plastome sequence
Abstract In this study, we quantify and document the distribution and organization of cpSSRs in the chloroplast genome of 31 Eucalyptus species. Our sample included all previously sequenced plastomes of Eucalyptus species available from the NCBI online database. We processed the complete cpDNA sequences and identified mono-, di-, tri-, tetra-, penta-, and he

7. Genetic Resistance to Rust of Eucalyptus urophylla Progenies
ABSTRACT This study assessed the genetic variability in open-pollinated progenies of Eucalyptus urophylla for resistance to rust (Puccinia psidii). The progeny trial was conducted on a statistical randomized block design with 20 progenies, five plants per plot, and nine replications. Analysis of variance showed high genetic variability for the studied trait,

8. Genetic variation for growth and selection in adult plants of Eucalyptus badjensis
Abstract The aim of this study was to evaluate Eucalyptus badjensis concerning the genetic variation for growth traits and the potential of the species in supporting a breeding programme. The field trial was a provenance/progeny test established in Campina da Alegria, Santa Catarina, Brazil (latitude 26°52′05.1″ S, longitude 51°48′47.5″ W, altitude

9. Avaliação do metabolismo primário da região cambial e casca de Eucalyptus grandis / Evaluation of the primary metabolism of Eucalyptus grandis cambial region and bark
Eucalyptus genus is the most widely planted hardwood crop in the world because of its superior growth, broad adaptability and multipurpose wood properties. In today\ s \"new carbon economy\", eucalypts are receiving attention as fast-growing, short-rotation, renewable biomass crop for energy production. In spite of its economical importance, little informati

10. Minimizing inter-genotypic competition effects to predict genetic values and selection in forestry genetic tests
The effect of competition is an important source of variation in breeding experiments. This study aimed to compare the selection of plants of open-pollinated families of Eucalyptus with and without the use of competition covariables. Genetic values were determined for each family and tree and for the traits height, diameter at breast height and timber volume

12. Genomic selection in Eucalyptus: marker assisted selection coming to reality in forest trees.
Genomic selection (GS) involves selection decisions based on genomic breeding values estimated as the sum of the effects of genome-wide markers capturing most QTLs for the target trait(s). GS is revolutionizing breeding practice for complex trait in domestic animals. The same approach and concepts can be readily applied to forest tree breeding. Trees also ha
