Cowpea Genetic maps

Cowpea:

  • Lucas et al. 2011 reported a consensus genetic map of cowpea [Vigna unguiculata (L.) Walp.] and synteny to other legumes based on EST-derived SNPs. A consensus map containing 1107 EST-derived SNP markers (856 bins) on 11 linkage groups (680 cM) was constructed from 13 population-specific maps.
  • Agbicodo et al. 2010 reported construction of genetic linkage map of cowpea from the set of 113 RILs developed from cross between Danila and TVu7778 consisted of 282 SNP markers. The markers were selected from the 1536 SNP genotyping array used for the consensus map of cowpea (Muchero et al.. 2009). Only markers with minor allele frequencies >0.3 were used. The map consisted of 11 linkage groups (LGs) and a total size of 633 cM.
  • Muchero et al. 2009 reported development and validation of EST-derived SNP assay for cowpea and its application in consensus map building. An illumina 1,536-SNP GoldenGate array was developed and used for genotyping of RILs from six mapping populations. Of these, 928 were incorporated into a consensus genetic map spanning 680 cM with 11 linkage groups and an average marker distance of 0.73 cM.
  • Ouédraogo et al. 2002 reported genetic linkage map for cowpea (Vigna unguiculata L.) developed using AFLP, RFLP, RAPD, and biochemical markers. RIL derived from the cross between 'IT84S-2049' and '524B' was genotyped with 242 molecular markers (Mostly AFLP). These markers along with previously mapped 181 random amplified polymorphic DNA (RAPD), restriction fragment length polymorphism (RFLP), AFLP were used for construction of genetic map. The genetic map develop consists of 11 linkage groups (LGs) spanning a total of 2670 cM, with an average distance of 6.43 cM.
