Azevedo, Alcinei Mistico; Andrade júnior, Valter Carvalho de; Santos, Albertir Aparecido dos; Sousa Júnior, Aderbal Soares de; Oliveira, Altino Júnior Mendes; Ferreira, Marcos Aurélio Miranda.
 Variance components must be obtained to estimate genetic parameters and predict breeding values. This information can be obtained through Bayesian inference. When multiple traits are evaluated, Bayesian inference can be used in multi-trait models. The objective of this study was to obtain estimates of genetic parameters, gains with selection, and genetic correlations among traits. Likewise, we aim to predict the genetic values and select the best kale genotypes using the Bayesian approach in a multi-trait linear model. The following traits were evaluated: stem diameter, plant height, number of shoots, number of marketable leaves and fresh weight of leaves using Bayesian inference in 22 kale genotypes. The experiment consisted of a randomized block design...

Barbosa, Ana Carla Borges; Oliveira, Iomar Ramos; Malhado, Ana Claudia Mendes; Carneiro, Paulo Luiz Sousa; Martins Filho, Raimundo; Malhado, Carlos Henrique Mendes.
The semi-arid region of Brazil represents approximately 57% of the northeastern territory. The main economic activity in this region is agriculture and livestock, in most cases, using traditional technologies. However, there is little published information currently available on cattle-raising in this part of Brazil. The objective of this study was to estimate genetic parameters and trends for productive and reproductive traits of Nellore cattle raised in semi-arid region of northeastern Brazil. Data were collected on weight-adjusted at 205 (W205), 365 (W365) and 550 (W550) days of life, age at first calving (AFC), calving interval (CI) and scrotal circumference (SC) at 550 days of life of cattle born between 1965 and 2011. Estimates of covariance and...

COPATI,MARIANE G.F.; ALVES,FLÁVIA M.; DARIVA,FRANÇOISE D.; PESSOA,HERIKA P.; DIAS,FELIPE O.; CARNEIRO,PEDRO C.S.; CARNEIRO,DERLY J.H.; NICK,CARLOS.
Abstract: This work aimed to study the inheritance of resistance to Phytophthora infestans in tomato plants, using the maximum likelihood estimation function. The susceptible cultivar Santa Clara (Solanum lycopersicum) was used as the female genitor and the P. infestans resistant S. habrochaites f. glabratum accession (BGH 6902) as the male genitor. F1 plants from the crossing were self-pollinated to produce F2 progenies, and also backcrossed with PR and PS to produce BC1:R and BC1:S generations, respectively. The tomato plants were inoculated 50 days after transplanting. Disease severity was evaluated via a diagrammatic scale. Comparison of the genetic models created using the maximum likelihood function revealed that the inheritance of resistance to P....

Tambarussi,Evandro Vagner; Sebbenn,Alexandre Magno; Moraes,Mário Luiz Teixeira de; Zimback,Léo; Palomino,Edwin Camacho; mori,Edson seizo.
The aims of this work were to estimate the coefficient of relatedness within families and the genetic parameters for growth related traits in a progeny test from an open-pollinated variety of Pinus caribaea Morelet hondurensis Barret & Golfari, established in Mato Grosso do Sul State, Brazil. The experimental design was the triple 10 x 10 lattice, with 96 families, three replicates, and ten plants per plot. Fourteen years after planting, the trial was measured for the following traits: total height, diameter at breast height (DBH), and true volume. The estimation of coefficients of relatedness within family from microsatellite loci indicated that families are true half-sibs (^r xy = 0.253). Thus, the additive genetic variance (σ2A) can be estimated...

Estimation of genetic parameters in the analysis of square lattice experiment group Bragantia
VIANA,JOSÉ MARCELO SORIANO; REGAZZI,ADAIR JOSÉ.
Aiming to demonstrate how to obtain unbiased estimates of genetic parameters of base populations, unaffected by genotype x environment effects, this paper presents the variance and covariance components of the intra-block analysis of a group of square lattice experiments and the estimators of the components associated to treatment effect. Random model and mixed models with environment effect fixed and other effects random are considered. In the analysis with treatments not corrected for blocks/replications/environments, the estimators of the variance and covariance components due to treatment effect are different from those of the analysis considering the complete block model. Data from two experiments of a breeding program of Eucalyptus pyrocarpa were...

Multi-Trait analysis of growth traits: fitting reduced rank models using principal components for Simmental beef cattle Ciência Rural
Mota,Rodrigo Reis; Costa,Edson Vinícius; Lopes,Paulo Sávio; Nascimento,Moyses; Silva,Luciano Pinheiro da; Silva,Fabyano Fonseca e; Marques,Luiz Fernando Aarão.
ABSTRACT: The aim of this research was to evaluate the dimensional reduction of additive direct genetic covariance matrices in genetic evaluations of growth traits (range 100-730 days) in Simmental cattle using principal components, as well as to estimate (co)variance components and genetic parameters. Principal component analyses were conducted for five different models-one full and four reduced-rank models. Models were compared using Akaike information (AIC) and Bayesian information (BIC) criteria. Variance components and genetic parameters were estimated by restricted maximum likelihood (REML). The AIC and BIC values were similar among models. This indicated that parsimonious models could be used in genetic evaluations in Simmental cattle. The first...
