Data from: QTL detection power of multi-parental RIL populations in Arabidopsis thaliana

Jonas R. Klasen, Hans-Peter Piepho, Benjamin Stich & H-P Piepho
A major goal of today's biology is to understand the genetic basis of quantitative traits. This can be achieved by statistical methods that evaluate the association between molecular marker variation and phenotypic variation in different types of mapping populations. The objective of this work was to evaluate the statistical power of QTL detection of various multi-parental mating designs as well as to assess the reasons for the observed differences. Our study was based on empirical...

Data from: Comparison of biometrical models for joint linkage association mapping

Wenxin Liu, Manje Gowda, Hans Peter Maurer, Sandra Fischer, Axel Schechert, Jochen C. Reif & Tobias Würschum
Joint linkage association mapping (JLAM) combines the advantages of linkage mapping and association mapping, and is a powerful tool to dissect the genetic architecture of complex traits. The main goal of this study was to use a cross-validation strategy, resample model averaging and empirical data analyses to compare seven different biometrical models for JLAM with regard to the correction for population structure and the quantitative trait loci (QTL) detection power. Three linear models and four...

Data from: Islands and streams: clusters and gene flow in wild barley populations from the Levant

Sariel Hübner, Torsten Günther, Andrew Flavell, Eyal Fridman, Andreas Graner, Abraham Korol & Karl J. Schmid
The domestication of plants frequently results in a high level of genetic differentiation between domesticated plants and their wild progenitors. This process is counteracted by gene flow between wild and domesticated plants because they are usually able to inter-mate and to exchange genes. We investigated the extent of gene flow between wild barley Hordeum spontaneum and cultivated barley Hordeum vulgare, and its effect on population structure in wild barley by analyzing a collection of 896...
