Linkage mapping is relevant to modern plant biology and provides a framework for downstream analyses including quantitative trait loci identification, map‐based cloning, assessment of diversity, association mapping, and molecular breeding. Here, we report a consensus genetic map of cowpea [Vigna unguiculata (L.) Walp.] and synteny to other legumes based on expressed sequence tag (EST)‐derived single nucleotide polymorphisms (SNPs). In total, 1293 individuals representing 13 mapping populations were genotyped using an Illumina 1536 GoldenGate Assay. A consensus map containing 1107 EST‐derived SNP markers (856 bins) on 11 linkage groups (680 cM) was constructed from 13 population‐specific maps. This effort combined six new population‐specific maps and seven revised population‐specific maps to construct an improved consensus map with 33% more bins, 19% more markers, and improved marker order when compared to the previous cowpea SNP consensus map. Comparative and whole genome visualizations are presented as a framework for discussing map quality and synteny with soybean [Glycine max (L.) Merr.].
