Figure 1. Positions of quantitative trait loci (QTLs) for the 13 traits as calculated using multiple QTL model (MQM) mapping, the optimized map for the respective trait and least square means of four replicates per genotype (for description of the traits, see Tables 1, 2, and 3). The maximum logarithm of odds (LOD) score position of each QTL is indicated with an arrow and a bar represents the interval between two positions obtained at LOD scores two units lower than the maximal score. Genetic linkage map of a red clover population based on 254 F₁ genotypes, 42 simple sequence repeat (SSR) and 216 amplified fragment length polymorphism (AFLP) loci as reported by Herrmann et al. (2006). Locus names consist of a denomination of the origin of the parental alleles (B = biparental locus; C and V = monoparental locus heterozygous in the parent from the cultivars Corvus and Violetta, respectively), followed by the locus name (standard primer combination code [Keygene, Wageningen, the Netherlands] followed by the allele size in relative migration units for AFLP loci or the prefix TPSSR and RCS followed by an identification number for SSR loci).
