Prediction of maize hybrid performance using similarity in state and similarity by descent information
Authors: D.V. Ferreira, R.G. Von Pinho, M. Balestre and R.L. Oliveira
We evaluated the efficiency of the best linear unbiased predictor (BLUP) and the influence of the use of similarity in state (SIS) and similarity by descent (SBD) in the prediction of untested maize hybrids. Nine inbred lines of maize were crossed using a randomized complete diallel method. These materials were genotyped with .. Read More»

Effects of using phenotypic means and genotypic values in GGE biplot analyses on genotype by environment studies on tropical maize (Zea mays)
Authors: I.S.C. Granato, R. Fritsche-Neto, M.D.V. Resende and F.F. Silva
The objective of this study was to examine the effects of the type and intensity of nutritional stress, and of the statistical treatment of the data, on the genotype x environment (G x E) interaction for tropical maize (Zea mays). For this purpose, 39 hybrid combinations were evaluated under low- and high-nitrogen and -phospho.. Read More»

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»

Genetic parameters and prediction of genotypic values for root quality traits in cassava using REML/BLUP
Authors: E.J. Oliveira, F.A. Santana, L.A. Oliveira and V.S. Santos
The aim of this study was to estimate the genetic parameters and predict the genotypic values of root quality traits in cassava (Manihot esculenta Crantz) using restricted maximum likelihood (REML) and best linear unbiased prediction (BLUP). A total of 471 cassava accessions were evaluated over two years of cultivatio.. Read More»

Comparison of BLUE and BLUP/REML in the selection of clones and families of potato (Solanum tuberosum)
Authors: C.A. Ticona-Benavente and D.F. da Silva Filho
The use of best linear unbiased prediction/restricted maximum likelihood (BLUP/REML) in perennial crops and animal breeding enhances selection gain. However, its advantage with respect to annual crops is not clear. We compared the BLUP and best linear unbiased estimator selection efficiency in the breeding of various potato generations. This was done by s.. Read More»
