A poster presented at the 2012 Global Pulse Researchers Meeting, Kigali, Rwanda- “Transforming Grain-Legume Systems to Enhance Nutrition and Livelihoods”. Abstract: Genomics is central to modern breeding efforts. High-throughput genotyping can be used to construct genetic maps. These are key components of molecular assisted breeding. The most powerful genetic maps should be capable of various applications and should integrate information from different populations and species. In cowpea (Vigna unguiculata), a 1536 SNP assay (Muchero et al 2009) was applied to thirteen breeding populations (1,293 individuals) and used to construct population-specific genetic maps. These maps were then integrated to develop a robust consensus genetic map with 1107 EST-derived SNP markers (856 bins) (Lucas et al 2011). Some applications of the consensus genetic map are demonstrated including comparative genomics, quantitative trait characterization, and map-based cloning. Please explore the HarvEST database ( for a plethora of open access information concerning this work among others.
