A bayesian genomic regression model with skew normal random errors
(Genetics Society of America, 2018)
Genomic selection (GS) has become a tool for selecting candidates in plant and animal breeding programs. In the case of quantitative traits, it is common to assume that the distribution of the response variable can be ...
Genomic-enabled prediction accuracies increased by modeling genotype × environment interaction in durum wheat
(Crop Science Society of America, 2018)
Genomic prediction studies incorporating genotype × environment (G×E) interaction effects are limited in durum wheat. We tested the genomic-enabled prediction accuracy (PA) of Genomic Best Linear Unbiased Predictor (GBLUP) ...
Genomic-enabled prediction based on molecular markers and pedigree using the Bayesian linear regression package in R
The availability of dense molecular markers has made possible the use of genomic selection in plant and animal breeding. However, models for genomic selection pose several computational and statistical challenges and require ...
Linear selection indices in modern plant breeding
Indirect selection using reference and probe genotype performance in multi-environment trials
There is a substantial challenge in identifying appropriate cultivars from databases for introduction into a breeding program. We propose an indirect selection procedure that illustrates how strategically designed ...
Bayesian estimation of the additive main effects and multiplicative interaction model
Much research has been conducted using least squares estimates of the linear?bilinear model additive main effects and multiplicative interaction (AMMI). The main difficulty with the standard linear?bilinear models is that ...
Genomic selection and prediction in plant breeding
The availability of thousands of genome-wide molecular markers has made possible the use of genomic selection in plants and animals. However, the evaluation of models for genomic selection in plant breeding populations ...
Gene effects and heterosis for grain iron and zinc density in pearl millet (Pennisetum glaucum (L.) R. Br)
Pearl millet [Pennisetum glaucum (L.) R. Br.] is a major warm-season cereal, grown primarily for grain production in the arid and semi-arid tropical regions of Asia and Africa. Iron (Fe) and zinc (Zn) deficiencies have ...
Genomic prediction of breeding values when modeling genotype × environment interaction using pedigree and dense molecular markers
Genomic selection (GS) has become an important aid in plant and animal breeding. Multienvironment (multitrait) models allow borrowing of information across environments (traits), which could enhance prediction accuracy. ...
Comparing molecular marker combinations in natural or artificial populations
Many ecological studies compare the genetic structure of (natural or arti_cial) popula-tions across di_erent (spatial and/or temporal) environments. Genotyping, using modern high-throughput molecular maker technologies, ...
