Fig. 3From: De novo SNP discovery and genetic linkage mapping in poplar using restriction site associated DNA and whole-genome sequencing technologiesThe genetic map of linkage groups SLG1-SLG19 for the paternal P. simonii ‘L-3’. The length of each linkage group is presented under the linkage group name. Each SNP is named by the contig number of the rough reference sequence of P. simonii and its position on it, prefixed with letter SBack to article page
