SNP-BLUP, G-BLUP ja H-BLUP - johdanto genomisiin arvosteluihin

Suomen Maataloustieteellisen Seuran Tiedote, 2012
Genominen valinta tarkoittaa eläimen (ja kasvien) jalostusarvon ennustamista ja valintapäätöksen tekemistä yksilön DNA:n eli SNP- markkeritietojen perusteella. Viime vuosina genomisten jalostusarvojen laskentaan on kehitelty useita malleja. Yksinkertaisessa DNA markkeri eli SNP-BLUP menetelmään perustuvassa mallissa SNP-markkerivaikutuksia käsitellään ...

Avoiding the misuse of BLUP in behavioural ecology [PDF]

Behavioral Ecology, 2017
Having recognized that variation around the population-level "Golden Mean" of labile traits contains biologically meaningful information, behavioural ecologists have focused increasingly on exploring the causes and consequences of individual variation in behaviour.

Single-step genomic BLUP with many metafounders

Frontiers in Genetics, 2022
Single-step genomic BLUP (ssGBLUP) model for routine genomic prediction of breeding values is developed intensively for many dairy cattle populations. Compatibility between the genomic (G) and the pedigree (A) relationship matrices remains an important challenge required in ssGBLUP.

Controlling the Overfitting of Heritability in Genomic Selection through Cross Validation. [PDF]

, 2017
In genomic selection (GS), all the markers across the entire genome are used to conduct marker-assisted selection such that each quantitative trait locus of complex trait is in linkage disequilibrium with at least one marker.

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-

An Upper Bound for Accuracy of Prediction Using GBLUP. [PDF]

, 2016
This study aims at characterizing the asymptotic behavior of genomic prediction R2 as the size of the reference population increases for common or rare QTL alleles through simulations.

Single-step genomic evaluation for growth traits in a Mexican Braunvieh cattle population [PDF]

Animal Bioscience, 2023
Objective The objective was to compare (pedigree-based) best linear unbiased prediction (BLUP), genomic BLUP (GBLUP), and single-step GBLUP (ssGBLUP) methods for genomic evaluation of growth traits in a Mexican Braunvieh cattle population. Methods Birth (

Importance of BLUP method in plant breeding

Journal of Plant Science and Phytopathology, 2022
Introduction: The most desirable linear neutral prediction (BLUP) is a standard method for estimating the random effects of a hybrid model. This approach was originally developed in animal breeding to estimate breeding values and is now widely used in many fields of research.

QTL mapping of spike fertility index in bread wheat

Crop Breeding and Applied Biotechnology, 2021
Spike fertility index (SF) is a trait easily measured at maturity and strongly associated with the number of grains per unit area. In order to identify genomic regions involved in SF control, a biparental (Baguette 10 × Klein Chajá) population of 80 ...

Stability, performance and participatory evaluation of potato varieties under rain-fed and irrigation conditions at Southeast, Ethiopia

International Journal of Agricultural Research, Innovation and Technology
The goal of potato breeding is to develop widely adaptable, highly productive cultivars that farmers would prefer. The objective of this study was to evaluate the performance and stability of potato varieties linking the preferences of smallholder ...
