Journal ArticleDOI
Comparison of mixed-model approaches for association mapping.
Benjamin Stich,Jens Möhring,Hans-Peter Piepho,Martin Heckenberger,Edward S. Buckler,Edward S. Buckler,Albrecht E. Melchinger +6 more
TL;DR: The mixed-model association-mapping approaches using a kinship matrix estimated by REML are more appropriate for association mapping than the recently proposed QK method with respect to (i) the adherence to the nominal α-level and (ii) the adjusted power for detection of quantitative trait loci.
Journal ArticleDOI
Population structure and genetic diversity in a commercial maize breeding program assessed with SSR and SNP markers
Delphine Van Inghelandt,Delphine Van Inghelandt,Albrecht E. Melchinger,Claude Lebreton,Benjamin Stich +4 more
TL;DR: The results suggested that the same conclusions regarding the structure and the diversity of heterotic pools could be drawn from both markers types, and it was proposed that between 7 and 11 times more SNPs than SSRs should be used for analyzing population structure and genetic diversity.
Journal ArticleDOI
Linkage disequilibrium in European elite maize germplasm investigated with SSRs
Benjamin Stich,Albrecht E. Melchinger,Matthias Frisch,Hans Peter Maurer,Martin Heckenberger,Jochen C. Reif +5 more
TL;DR: The results indicate that a high proportion of the observed LD is generated by forces, such as relatedness, population stratification, and genetic drift, which cause a high risk of detecting false positives in association mapping.
Journal ArticleDOI
A high-density SNP genotyping array for Brassica napus and its ancestral diploid species based on optimised selection of single-locus markers in the allotetraploid genome

Higgins,Joerg Plieske,Ralf Wieseke,Christine Sidebottom,Yogendra Khedikar,Jacqueline Batley,Dave Edwards,Jinling Meng,Ruiyuan Li,Cindy Lawley,Jérôme Pauquet,Benjamin Laga,Wing Cheung,Federico L. Iniguez-Luy,Emmanuelle Dyrszka,Stephen Rae,Benjamin Stich,Rod J. Snowdon,Andrew G. Sharpe,Martin W. Ganal,Isobel A. P. Parkin +21 more
TL;DR: A high-density single nucleotide polymorphism (SNP) Illumina Infinium array, containing 52,157 markers, was developed for the allotetraploid Brassica napus, a valuable tool for genetic fine mapping and genome-wide association studies in B. napus and its progenitor genomes.
Journal ArticleDOI
Patterns of molecular variation in a species-wide germplasm set of Brassica napus
TL;DR: The population structure of a large and diverse set of B. napus inbred lines was examined, and a decay of genetic diversity with more recent release dates and reduced levels of erucic acid and glucosinolates was observed.
