Journal ArticleDOI
Genome-Wide Prediction of Traits with Different Genetic Architecture Through Efficient Variable Selection
Valentin Wimmer,Christina Lehermeier,Theresa Albrecht,Hans-Jürgen Auinger,Yu Wang,Chris-Carolin Schön +5 more
TL;DR: The results demonstrate that due to long-range LD, medium heritabilities, and small sample sizes, superiority of variable selection methods cannot be expected in plant breeding populations even for traits like FRIGIDA gene expression in Arabidopsis and flowering time in rice.
Journal ArticleDOI
Usefulness of Multiparental Populations of Maize (Zea mays L.) for Genome-Based Prediction
Christina Lehermeier,Nicole C. Krämer,Eva Bauer,Cyril Bauland,Christian Camisan,Laura Campo,Pascal Flament,Albrecht E. Melchinger,Monica A. Menz,Nina Meyer,Laurence Moreau,Jesús Moreno-González,Milena Ouzunova,Hubert Pausch,Nicolas Ranc,Wolfgang Schipprack,Manfred Schönleben,Hildrun Walter,Alain Charcosset,Chris-Carolin Schön +19 more
TL;DR: This work evaluated testcross performance of 1652 doubled-haploid maize lines that were genotyped with 56,110 single nucleotide polymorphism markers and phenotyped for five agronomic traits in four to six European environments and theoretically and empirically investigated marker linkage phases across multiparental populations.
Journal ArticleDOI
Linkage Disequilibrium with Linkage Analysis of Multiline Crosses Reveals Different Multiallelic QTL for Hybrid Performance in the Flint and Dent Heterotic Groups of Maize
Héloïse Giraud,Christina Lehermeier,Eva Bauer,Matthieu Falque,Vincent Segura,Cyril Bauland,Christian Camisan,Laura Campo,Nina Meyer,Nicolas Ranc,Wolfgang Schipprack,Pascal Flament,Albrecht E. Melchinger,Monica A. Menz,Jesús Moreno-González,Milena Ouzunova,Alain Charcosset,Chris-Carolin Schön,Laurence Moreau +18 more
TL;DR: Two new nested association mapping designs adapted to European conditions were derived from the complementary dent and flint heterotic groups of maize, with favorable allelic effects detected in both groups open perspectives for improving biomass production.
Journal ArticleDOI
Model training across multiple breeding cycles significantly improves genomic prediction accuracy in rye (Secale cereale L.)
Hans-Jürgen Auinger,Manfred Schönleben,Christina Lehermeier,Malthe Schmidt,Viktor Korzun,Hartwig H. Geiger,Hans-Peter Piepho,Andres Gordillo,Peer Wilde,Eva Bauer,Chris-Carolin Schön +10 more
TL;DR: Genomic prediction accuracy can be significantly increased by model calibration across multiple breeding cycles as long as selection cycles are connected by a sufficient number of common ancestors and prediction accuracy has not reached a plateau when increasing sample size.
Journal ArticleDOI
Assessment of Genetic Heterogeneity in Structured Plant Populations Using Multivariate Whole-Genome Regression Models
TL;DR: An assessment of prediction accuracy features cases where ignoring population structure leads to a parsimonious more powerful model as well as others where the multivariate and stratified approaches have higher predictive power.
