Background: Productivity of cowpea [Vigna unguiculata (L.) Walp] in sub-Sahara Africa is curtailed by a lack of\nfarmer-preferred and improved cultivars and modern production technologies. The objectives of the study were to\ndetermine the extent of genetic diversity present among a collection of cowpea accessions from Zambia and\nMalawi using phenotypic traits and single nucleotide polymorphism (SNP) markers and, to select distinct and\ncomplementary parental lines for cultivar development. One hundred cowpea genotypes were evaluated for\nagronomic traits in two selected sites in Zambia, using .....................
