Oscilação genética em diferentes tamanhos de população sob seleção

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2002
Com o objetivo de estudar alguns fatores que influenciam a seleção em longo prazo, foram utilizados dados simulados pelo programa GENESYS, considerando: duas herdabilidades, dois tamanhos de população, três níveis de repetição e 20 gerações, para ...

Multi‐Breed Genomic Predictions for Average Daily Gain in Three Italian Beef Cattle Breeds

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Marchigiana, Chianina, and Romagnola are three Italian autochthonous beef cattle breeds that have been historically selected for meat production. Recent advancements suggest that the use of genomic data and multi‐breed (MB) models to combine information from different breeds may help to increase the accuracies of genomic predictions, in ...

Enhancing Genome-Enabled Prediction by Bagging Genomic BLUP

PLoS ONE, 2014
We examined whether or not the predictive ability of genomic best linear unbiased prediction (GBLUP) could be improved via a resampling method used in machine learning: bootstrap aggregating sampling ("bagging"). In theory, bagging can be useful when the predictor has large variance or when the number of markers is much larger than sample size ...

Genomic Prediction Ability for Novel Profitability Traits Using Different Models in Nelore Cattle

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT The aim of this study was to assess the accuracy, bias and dispersion of genomic predictions for accumulated profitability (APF) and profit per kilogram of liveweight gain (PFT) in Nelore cattle using different prediction approaches. The dataset consisted of 3969 phenotypic records for each trait. The pedigree harboured information from 38,930

Single‐Step Genomic Predictions for Growth and Carcass Traits in Nordic Charolais and Hereford Cattle

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT In order to investigate the applicability and efficiency of genomic selection for growth and carcass traits in Nordic beef cattle, single‐step genomic BLUP (ssGBLUP) was applied in 4321 Charolais and 4532 Hereford animals with information on approximately 43,000 SNPs each.

Genome‐wide association studies reveal genetic diversity and regulatory loci underlying dwarfing traits in banana

Journal of Integrative Plant Biology, EarlyView.
The introgression of Musa itinerans into cultivated banana varieties has expanded their genetic diversity, enhancing breeding potential. Genome‐wide association studies and functional validation confirmed the transcription factor gene MabHLH30 as a critical regulator of plant stature, enabling the implementation of marker‐assisted selection to ...

Structural Variants Contribute to Phenotypic Variation in Maize

Molecular Ecology, EarlyView.
ABSTRACT Comprehensively identifying the loci shaping trait variation has been challenging, in part because standard approaches often miss many types of genetic variants. Structural variants (SVs), especially transposable elements (TEs), are likely to affect phenotypic variation but we lack methods that can detect polymorphic SVs and TEs using short ...

Molecular breeding approaches for the improvement of oil content and fatty acid composition in exotic‐derived maize germplasm

New Phytologist, EarlyView.
Summary Molecular breeding strategies such as genome‐wide association studies (GWAS) and genomic prediction have revolutionized crop improvement by enhancing selection accuracy and genetic gains. Through a comprehensive evaluation of a large set of maize lines from Germplasm Enhancement of Maize (BGEM) and their testcross hybrids, we aimed to ...

The BLUP method in evaluation of breeding values of Russian spring wheat lines using micro- and macroelements in seeds

Вавиловский журнал генетики и селекции
Genomic selection is a technology that allows for the determination of the genetic value of varieties of agricultural plants and animal breeds, based on information about genotypes and phenotypes. The measured breeding value (BV) for varieties and breeds
