Die Robustheit von BLUP und EBLUP

, 1999
. 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".

Analysis of alternative models treating herd × year effects as fixed or random

Czech Journal of Animal Science, 2004
The analysis was conducted of the national database of station tests carried out between May 1996- February 2001, using the Hungarian Large White breed. Days of test, total amount of consumed feed and valuable cuts were taken into the analysis. Using the

Selection of Apple Trees (Malus domestica Borkh.) Based on Genetic Parameters Estimated Through Mixed Models

Plant Breeding, EarlyView.
ABSTRACT In Brazilian apple breeding (Malus domestica Borkh.), Active Germplasm Banks are providing the genetic diversity required for selecting genotypes with low chilling requirements, high yield and superior fruit quality. This study estimated genetic parameters and perform genotype selection based on phenotypic traits from the IDR‐Paraná breeding ...

Unknown parent groups and truncated pedigree in single-step genomic evaluations of Murrah buffaloes

Journal of Dairy Science
: Missing pedigrees may produce bias in genomic evaluations. Thus, strategies to deal with this problem have been proposed as using unknown parent groups (UPG) or truncated pedigrees.

Using genealogy to improve selection efficiency of pedigree method Emprego da genealogia para melhorar eficiência seletiva no método pedigree

Scientia Agricola, 2008
In the pedigree method of conducting an autogamous population of segregating plants, the genealogy of the progenies is registered. Although labor-intensive, these data are rarely used.

Enhancing Predictive Ability of Agronomic and Quality Traits in Ethiopian Malting Barley (Hordeum vulgare L.) Using Spectral Variable Selection Methods

Plant Breeding, EarlyView.
ABSTRACT Phenomic selection (PS) offers a cost‐effective, breeder‐friendly approach for public breeding programmes with limited access to genotyping or restricted financial resources for laboratory infrastructure. Since PS relies on high‐throughput phenotyping data, which is often derived from near‐infrared spectroscopy (NIRS) of harvested seeds ...

Genetic Architecture of Southern Stem Canker Resistance in Elite Southern Soybean (Glycine max [L.] Merr.) Germplasm

Plant Breeding, EarlyView.
ABSTRACT Southern stem canker (SSC), caused by the fungus Diaporthe aspalathi, is one of the major constraints to soybean (Glycine max [L.] Merr.) production in the southern United States and South America. Genetic resistance is the most effective strategy for managing SSC; however, the genetic architecture underlying resistance in elite southern ...

Simultaneous fitting of genomic-BLUP and Bayes-C components in a genomic prediction model

Genetics Selection Evolution, 2017
Background The rapid adoption of genomic selection is due to two key factors: availability of both high-throughput dense genotyping and statistical methods to estimate and predict breeding values.

From Arabidopsis to Crop Prediction: Enrichment and Limitations of Tree‐Based SHAP for Marker Prioritization in Plant Breeding

Plant Breeding, EarlyView.
ABSTRACT Genomic prediction is widely used in plant breeding, but feature‐attribution scores from predictive models are sometimes interpreted as evidence for trait‐associated or causal loci. We evaluated whether global SHapley Additive exPlanations (SHAP) from XGBoost and LightGBM prioritize markers or genomic windows enriched for signals from mixed ...
