A novel individual-tree mixed model to account for competition and environmental heterogeneity: a Bayesian approach
(Springer Heidelberg, 2015-12)
Negative correlation caused by competition among individuals and positive spatial correlation due to environmental heterogeneity may lead to biases in estimating genetic parameters and predicting breeding values (BVs) from ...
Identification and joint modeling of competition effects and environmental heterogeneity in three Douglas-fir (Pseudotsuga menziesii var. menziesii) trials
(2016-12)
(Co)variance matrices for the assumed model, and thus the specification of the dispersion parameters, should take into account both the negative competition and the positive spatial correlations. In this context, we applied ...

Improving genetic analysis of corymbia citriodora subsp. variegata with single- And multiple-trait spatial-competition models
(Soc Amer Foresters, 2019-08-30)
Environmental heterogeneity and/or genetic and environmental competition were quantified on two growth traits, diameter at breast height and total height, and wood density in a progeny trial of Corymbia citriodora subsp. ...
Thinning strategies for Eucalyptus dunnii population: balance between breeding and conservation using spatial variation and competition model
(2021-10-01)
For continuous genetic gains over time, a balance between genetic gain and maintaining the genetic base must be a constant concern of forest breeders. This study aims at determining the best thinning strategies for a ...

Minimizing inter-genotypic competition effects to predict genetic values and selection in forestry genetic tests
(Universidade de São Paulo (USP), Escola Superior de Agricultura Luiz de Queiroz (ESALQ), 2011-12-01)
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 ...

Improving accuracy of breeding values by incorporating genomic information in spatial-competition mixed models
(Springer, 2017-10)
Climate change and the increasing demand for sustainable energy resources require urgent strategies to increase the accuracy of selection in tree breeding (associated with higher gain). We investigated the combined pedigree ...
