Cowpea bacterial blight (CoBB, Xanthomonas axonopodis pv. vignicola, Xav) is the most important bacterial disease of cowpea (Vigna unguiculata) because it prevalent in all major cowpea growing areas worldwide, and the use of host resistance is the primary method to control this disease. Genetic diversity and association analysis were conducted for CoBB(More)
To identify the genes responsible for yield related traits, and heterosis, massively parallel signature sequencing (MPSS) libraries were constructed from leaves, roots and meristem tissues from the two parents, 'Nipponbare' and '93-11', and their F1 hybrid. From the MPSS libraries, 1-3 million signatures were obtained. Using cluster analysis, commonly and(More)
The genetic diversity of cowpea was analyzed, and the population structure was estimated in a diverse set of 768 cultivated cowpea genotypes from the USDA GRIN cowpea collection, originally collected from 56 countries. Genotyping by sequencing was used to discover single nucleotide polymorphism (SNP) in cowpea and the identified SNP alleles were used to(More)
