Genetic architecture of flowering time in HEB-25. Barley chromosomes are indicated as colored bars on the inner circle, centromeres are highlighted as transparent boxes. a) Grey connector lines represent the genetic position of SNPs on the chromosomes. b) Frequency of QTL detection in 100 cross-validation runs via GWAS (0 to 100, grid line spacing: 25); markers with > 50 detections are colored in red. c) Additive effect of the SNP obtained from the BayesCπ genomic prediction model. d) Links in the center of the circle represent significant (PBON-HOLM < 0.05) di-genic interactions between SNP markers via GWAS. Clusters of significant SNP interactions are indicated by different colors. Position of candidate genes, potentially explaining major effects and epistatic effects, correspond to Table 1 and are indicated in blue outside the circle.
