Table 1 Composition of the F2 genetic map grouped by linkage group (LG) and detailed by number of SNP markers, number of non-redundant SNP markers, map lengths (in cM), number of SNP markers per scaffold, map length for each of the seven chromosomes (based on multiple SNPs and 1 SNP per scaffold) and number of DArT markers added per chromosome

From: Quantitative trait loci associated with different polar metabolites in perennial ryegrass - providing scope for breeding towards increasing certain polar metabolites
