Assessing the expected response to genomic selection of individuals and families in Eucalyptus breeding with an additive-dominant model
We report a genomic selection (GS) study of growth and wood quality traits in an outbred F2 hybrid Eucalyptus population (n=768) using high-density single-nucleotide polymorphism (SNP) genoty**. Going beyond pr...

Genetic map** of Eef1, a major effect QTL for early flowering in Eucalyptus grandis
An early flowering mutant plant of Eucalyptus grandis with normal vegetative growth was found in a nursery in northern Brazil. This mutant plant flowers at approximately 90 days from germination. A cross between ...

A microsatellite-based, gene-rich linkage map for the AA genome of Arachis (Fabaceae)
Cultivated peanut (Arachis hypogaea) is an important crop, widely grown in tropical and subtropical regions of the world. It is highly susceptible to several biotic and abiotic stresses to which wild species are ...

Retrospective selection of elite parent trees using paternity testing with microsatellite markers: an alternative short term breeding tactic for Eucalyptus
The conventional way to drive modifications in old forest tree seed orchards is to establish progeny trials involving each parent tree and then evaluate its contribution to the performance of the progeny by es...

Resistance to rust (Puccinia psidii Winter) in Eucalyptus: mode of inheritance and map** of a major gene with RAPD markers
Rust is one of the most-damaging eucalypt diseases in Brazil and is considered a potential threat to eucalypt plantations worldwide. To determine the mode of inheritance of resistance in the Eucalyptus grandis—Pu...

Conservation and synteny of SSR loci and QTLs for vegetative propagation in four Eucalyptus species
Conservation of microsatellite loci, heterozygous in Eucalyptus grandis, Eucalyptus urophylla, Eucalyptus tereticornis and Eucalyptus globulus, allowed us to propose homeologies among genetic linkage groups in th...

Towards a genus-wide reference linkage map for Eucalyptus based exclusively on highly informative microsatellite markers
A novel set of 50 highly polymorphic microsatellite markers were developed and mapped on existing RAPD framework maps of Eucalyptus grandis and E. urophylla. Together with the twenty previously developed microsa...

Genetic diversity of Brazilian oil palm (Elaeis oleifera H.B.K.) germplasm collected in the Amazon Forest
Elaeis oleifera or ‘caiaué’, a close relative of oil palm (E. guineensis), has some agronomic traits of great interest for the oil palm genetic breeding such as slow growth, oil quality (...

RAPD linkage map** of the shell thickness locus in oil palm (Elaeis guineensis Jacq.)
Shell thickness is an important trait in oil palm breeding programs and is the basis for the classification of the varieties of oil palm into the types dura, tenera and pisifera. This trait seems to be control...

Genetic linkage maps of Citrus sunki Hort. ex. Tan. and Poncirus trifoliata (L.) Raf. and map** of citrus tristeza virus resistance gene
A linkage map for Citrus sunki Hort. ex. Tan. and Poncirus trifoliate (L.) Raf cv. Rubidoux has been developed exploiting the pseudo-testcross map** strategy and RAPD markers. From controlled crosses 314 F1 zyg...

Development, characterization and map** of microsatellite markers in Eucalyptus grandis and E. urophylla
We report on the development, genetic characterization and linkage map** of a battery of SSR (simple sequence repeat) loci in Eucalyptus grandis and E. urophylla. This study reveals the abundance of SSRs in Eu...

Estimation of outcrossing rate in a breeding population of Eucalyptus urophylla with dominant RAPD and AFLP markers
Eucalyptus breeding is typically conducted by selection in open-pollinated progenies. As mating is controlled only on the female side of the cross, knowledge of outcrossing versus selfing rates is essential for ...

Pseudo-Testcross Map** Strategy Using RAPD Markers
Genetic linkage maps are powerful tools for detailed genetic analysis. Maps allow dissection of the architecture of polygenic traits by the investigation of the individual genomic segments underlying quantitat...

Molecular Markers, Forest Genetics, and Tree Breeding
Several years ago, Strauss et al. (1992) thoughtfully evaluated the application of molecular markers in forest tree breeding for marker aided selection. The purpose of their paper was to emphasize the limitati...

Genetic map** of QTLs controlling vegetative propagation in Eucalyptus grandis and E. urophylla using a pseudo-testcross strategy and RAPD markers
We have extended the combined use of the “pseudo-testcross” map** strategy and RAPD markers to map quantitative trait loci (QTLs) controlling traits related to vegetative propagation in Eucalyptus. QTL analyses...
