Adaptability and stability assessment of bean cultivars of the carioca commercial group by a Bayesian approach Agronomy
Euzebio, Milena Pierotti; Fonseca, Inês Cristina de Batista; Fonseca Júnior, Nelson da Silva; Nascimento, Moysés; Giordani, Willian; Gonçalves, Leandro Simões Azeredo.
 To develop new bean commercial cultivars, a series of experiments called Value for Cultivation and Use (VCU) assays are necessary. Bayesian analysis using information on prior VCU trials is an alternative to obtain greater precision during genotype selection. The objective of the present work was to select, under a Bayesian perspective, genotypes of the carioca bean from the state of Paraná that combine high adaptability and phenotypic stability, using information from previous VCU assays. This study used data from six experiments conducted in a randomized block design, in which the grain yield of 18 genotypes was assayed. To represent weakly informative prior distributions, the study used probability distributions with high variance; to represent...

Bayesian analysis of growth, stem straightness and branching quality in full-sib families of Eucalyptus globulus Bragantia
Mora,Freddy; Ballesta,Paulina; Serra,Nicolle.
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, branching quality and growth traits were based on a Bayesian modelling approach using Gibbs sampling. A Bayes Factor (BF) analysis supported the hypothesis of significant additive genetic variation for all traits under study. Conversely, the BF supported a model with significant dominance effects for the diameter at breast height and stem volume, which explained up to 25% of the phenotypic variation. The...
