Genetic linkage maps of LGs 1–4 from the NA 6 parental genotype of the F 1 (NA 6 × AU 6 ) cross. Nomenclature for the parental maps of the F1(NA6 × AU6) cross is as follows: EST-RFLP markers are indicated with xlp (co-dominant Lolium perenne locus) prefixes and gene-specific abbreviations, while EST-SSR are indicated with xpps prefixes, both as described in [50]; genomic DNA-derived (LPSSR) markers are indicated as xlpssr loci using the nomenclature described in [56]. SNP loci are designated according to the nomenclature xlp-gene name abbreviation-nucleotide coordinate-SNP identity [48]. For instance, xlpchijb-240cg on NA6 LG5 is derived from a chitinase class gene (LpCHIjb), and the SNP is a C-G transversion located at coordinate 240. DR gene SNP loci are indicated in bold red type, and corresponding RFLP loci in black bold italic type. R gene SNP loci (designated with xlprg prefixes, and numbered according to Table 2), are indicated in bold blue type. Auxiliary DR and R gene loci mapped using JOINMAP 3.0, but not MAPMAKER 3.0, are interpolated between flanking markers to provide approximate genetic map locations.
