Die Robustheit von BLUP und EBLUP [PDF]
Archives Animal Breeding, 1999 Abstract. Title of the paper: The Robustness of BLUP and EBLUP The expectations of BLP and BLUP used as estimator for fixed effects and as predictor for random effects were investigated concerning the property "unbiasedness". Different aspects of robustness research on prediction procedures are discussed.

Comparison of alternative approaches to single-trait genomic prediction using genotyped and non-genotyped Hanwoo beef cattle. [PDF]
, 2017 BackgroundGenomic predictions from BayesA and BayesB use training data that include animals with both phenotypes and genotypes. Single-step methodologies allow additional information from non-genotyped relatives to be included in the analysis. The single-

On Misspecification of Spatial Weight Matrix for Small Area Estimation in Longitudinal Analysis [PDF]
, 2012 The problem of prediction of subpopulation (domain) total is studied as in Rao (2003). Considerations are based on spatially correlated longitudinal data.

Choosing parent tropical wheat genotypes through genetic dissimilarity based on REML/BLUP
Crop Breeding and Applied Biotechnology, 2020 Parent selection is a crucial step in breeding programs. In the present study, we evaluated the genetic diversity in tropical wheat genotypes using best linear unbiased predictions (BLUPs) by different grouping methods. We identified potential parents to

Improving Genomic Prediction Using High-Dimensional Secondary Phenotypes
Frontiers in Genetics, 2021 In the past decades, genomic prediction has had a large impact on plant breeding. Given the current advances of high-throughput phenotyping and sequencing technologies, it is increasingly common to observe a large number of traits, in addition to the ...

Genetics Selection Evolution, 2020 Background Preselection of candidates, hereafter referred to as preselection, is a common practice in breeding programs. Preselection can cause bias and accuracy loss in subsequent pedigree-based best linear unbiased prediction (PBLUP).

Genomic prediction in a backcross population using relationship matrices [PDF]
Archives Animal BreedingBackcrossing is a widely used crossbreeding strategy for transferring desirable traits from a donor line into a recurrent parent population. Although genomic selection can accelerate genetic improvement in these populations, traditional models such as G ...

Revista de la Facultad de Ciencias Agrarias, 2021 Multi-trait best linear unbiased prediction (BLUP) is, generally, the most appropriate method to genetic evaluation because it considers the genetic and residual correlations among traits and conduct to higher selection accuracy.

Ecriture des équations du BLUP multicaractères [PDF]
Annales de Génétique et de Sélection Animale, 1982 This paper gives expressions for multiple trait BLUP equations when the same factors are influencing all traits. Two cases are discussed depending on whether the information on the traits is complete or not. When all traits are recorded and with only one random factor considered in the model, the problem is simplified because a canonical ...

The Plant Genome, 2019 Augmenting RR‐BLUP models with peak GWAS markers can hypothetically boost prediction accuracy We conducted a simulation study in maize and sorghum to test the performance of such models For most of the simulated traits, we observed a decrease in ...
