Genomic prediction for additive and dominance effects of censored traits in pigs
Authors: V.S. Santos, S. Martins Filho, M.D.V. Resende, C.F. Azevedo, P.S. Lopes, S.E.F. Guimar�£es and F.F. Silva
Age at the time of slaughter is a commonly used trait in animal breeding programs. Since studying this trait involves incomplete observations (censoring), analysis can be performed using survival models or modified linear models, for example, by sampling censored data from truncated normal distributions. For genomic selection,.. Read More»

Mixed models for selection of Jatropha progenies with high adaptability and yield stability in Brazilian regions
Authors: P.E. Teodoro, L.L. Bhering, R.D. Costa, R.B. Rocha and B.G. Laviola
The aim of this study was to estimate genetic parameters via mixed models and simultaneously to select Jatropha progenies grown in three regions of Brazil that meet high adaptability and stability. From a previous phenotypic selection, three progeny tests were installed in 2008 in the municipalities of Planaltina-DF (Midwest), Nova Porteirinha-MG (Southea.. Read More»

Mixed models identify physic nut genotypes adapted to environments with different phosphorus availability
Authors: P.E. Teodoro, B.G. Laviola, L.D. Martins, J.F.T. Amaral and W.N. Rodrigues
The aim of this study was to screen physic nut (Jatropha curcas) genotypes that differ in their phosphorous (P) use, using mixed models. The experiment was conducted in a greenhouse located in the experimental area of the Centro de Ciências Agrárias of the Universidade Federal do Espírito Santo, in Alegre, ES, Brazil. The experiment wa.. Read More»

Usefulness of the HMRPGV method for simultaneous selection of upland cotton genotypes with greater fiber length and high yield stability
Authors: F.J.C. Farias, L.P. Carvalho, J.L. Silva Filho and P.E. Teodoro
The harmonic mean of the relative performance of genotypic predicted value (HMRPGV) method has been used to measure the genotypic stability and adaptability of various crops. However, its use in cotton is still restricted. This study aimed to use mixed models to select cotton genotypes that simultaneously result in longer fiber length, higher fiber yield,.. Read More»

Variation in cassava germplasm for tolerance to post-harvest physiological deterioration
Authors: M.T. Venturini, L.R. Santos, C.I.A. Vildoso, V.S. Santos and E.J. Oliveira
Tolerant varieties can effectively control post-harvest physiological deterioration (PPD) of cassava, although knowledge on the genetic variability and inheritance of this trait is needed. The objective of this study was to estimate genetic parameters and identify sources of tolerance to PPD and their stability in cassava acce.. Read More»

Assessment of genetic divergence among coffee genotypes by Ward-MLM procedure in association with mixed models
Authors: W.P. Rodrigues, H.D. Vieira, P.E. Teodoro F.L. Partelli and D.H.S.G. Barbosa
Mixed linear models have been used for the analysis of the genetic diversity and provided further accurate results in crops such as eucalyptus, castor, and sugarcane. However, to date, research that combined this analysis with Ward-MLM procedure has not been reported. Therefore, the aim of the present study was to identify div.. Read More»

Correspondence between performance of Eucalyptus spp trees selected from family and clonal tests
Authors: C.A.F. Reis, F.M.A. Gon�§alves, L.N. Rosse, R.R.G.F. Costa and M.A.P. Ramalho
We examined the correspondence in performance between trees selected from a family test and their respective clones from a clonal test of Eucalyptus. Full-sib families were obtained from controlled pollination among individuals of Eucalyptus grandis and between E. grandis and E. urophylla. The hybridizations did not follow a f.. Read More»

Prediction of maize double-cross hybrids using the best linear unbiased prediction with microsatellite marker information
Authors: M. Balestre, R.G. Von Pinho and J.C. Souza
We examined the usefulness of the best linear unbiased prediction associated with molecular markers for prediction of untested maize double-cross hybrids. Ten single-cross hybrids from different commercial backgrounds were crossed using a complete diallel design. These 10 single-cross hybrids were genotyped with 20 microsatell.. Read More»
