Genetic evaluation and deviance analysis in an unbalanced provenance and progeny test of maté
Provedor de dados: 190
Autores: Sturion, José Alfredo; Resende, Marcos Deon Vilela de.
Likelihood ratio tests (LRT) were applied in an unbalanced provenance/progeny test of mate (Ilex paraguariensis A. St. Hil.). The trial was established in a randomized complete block design with seven provenances, 140 half sib families, ten blocks and six plants per linear plot. The spacing was 3 m x 2 m. The following conclusions were obtained from the deviance analysis (Anadev): all random effects and associated variance components and coefficients of determination (heritability and coefficients of determination of plots and provenances) were significant; there is enough genetic variability in both within and between provenance levels which can be adequately explored for breeding purposes.doi: 10.4336/2010.pfb.30.62.157

Reciprocal Recurrent Selection between Synthetic Multi Species Populations (RRSSMSP) of Eucalypt
Provedor de dados: 190
Autores: Resende, Marcos Deon Vilela de; Assis, Teotônio Francisco de.
It is proposed a breeding strategy for eucalypt, which congregates in an individual desirable traits belonging to different species and capture the heterosis for growth, stemming from several pair of species of known heterotic behavior. Such strategy relies on obtaining two synthetic multi species populations and posterior reciprocal recurrent selection (RRS) between them. It is called reciprocal recurrent selection between synthetic multi species populations (RRS-SMSP) and improves the traits drought, disease resistance, volume, density, yield and lignin content. Options for making the synthetic multi species populations are presented. The RRSSMSP is suitable for applying the genomic selection.

Genome wide selection (GWS) and maximization of the genetic improvement efficiency
Provedor de dados: 190
Autores: Resende, Marcos Deon Vilela de; Lopes, Paulo Sávio; Silva, Rogério Luíz da; Pires, Ismael Eleotério.
Genetic selection has been practiced by the best linear unbiased prediction (BLUP) method using phenotypic records. A first proposal for enhancement of the efficiency of this procedure was the marker assisted selection (MAS). Later, another method called genome wide selection - GWS was reported, which presents high accuracy for the selection based exclusively on markers, after predicting their genetic effects from phenotypic data in a sample of the population of selection. GWS is excellent for low heritable traits, while MAS is not. This paper presents the GWS methodology and simulates a case of its application, aiming at emphasizing its advantages over MAS. The relation between traditional BLUP and genomic BLUP is also detailed as well as the sample size...

Heart of palm harvesting and exploitation has reduced the natural reserves of açaí and juçara; hence, the peach palm is an excellent option as source of heart of palm that can reduce the pressure on these two species. The peach palm has high tillering and no post-harvest oxidation. An experiment in a randomized block design with 72 progenies of peach palm, 36 replications and a single tree plot was performed for five years at the experimental field of Embrapa in the Western Amazon. Genetic parameters were estimated using two mixed models, one based on progeny means and the second on joint information from crops. A repeatability analysis, genotype selection, and progeny selection were performed; the Mulamba and Mock selection index was determined; and...
