Modeling missing pedigree in single-step genomic BLUP [PDF]
Journal of Dairy Science, 2019 The objective was to compare methods of modeling missing pedigree in single-step genomic BLUP (ssGBLUP). Options for modeling missing pedigree included ignoring the missing pedigree, unknown parent groups (UPG) based on A (the numerator relationship matrix) or H (the unified pedigree and genomic relationship matrix), and metafounders.

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 ...

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.

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.

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 ...

Genetic parameters and multiple-trait selection in wheat genotypes
Pesquisa Agropecuária Tropical, 2021 Mixed models and multivariate analysis are powerful tools for selecting superior genotypes in plant breeding programs. The BLUP (best linear unbiased prediction) method has been used to predict genetic values without environmental effects ...

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 ...
