“…Cowpea grain comprises a high protein content (23%–32%), moderate quantity of lysine, minerals (Zn, Fe, manganese [Mn], boron [B], and copper [Cu]), vitamins A and B, amino acids (isoleucine and leucine), carbohydrates (<60%), and anti‐nutritional factors (tannin and phytic acid; Baptista et al., 2017; Elhardallou et al., 2015). The crop contains anti‐nutritional agents that not only make the grain less vulnerable to insect attack but also make it harder for both animals and humans to digest and absorb nutrients (Maia et al., 2000; Parmar et al., 2017; Simion, 2018).…”

Cowpea [Vigna unguiculata (L.) Walp] has the potential of contributing to eradication of hunger and malnutrition. The study objectives were to evaluate the variability of cowpea mutants, IITA and South African genotypes for protein content, selected minerals, phytic acid, and the bioavailability of Fe and Zn, to identify superior cowpea mutants, IITA and South African genotypes, and determine the correlation between measured characteristics. Thirty‐one cowpea genotypes were planted at five different environments in South Africa. Significant (P ≤ 0.05) genotype and genotype by environment interaction effects were observed for protein, minerals and phytic acid concentration. High broad‐sense heritability (> 50%) was observed for almost all the characteristics. Thirteen Namibian mutants, five International Institute for Tropical Agriculture (IITA) genotypes, and six South African genotypes that combined high protein, Fe and Zn were identified. The IITA genotype IT93K‐452‐1 and South African genotypes Oloyin and Orelu had good Fe bioavailability. Nine Namibian mutants, four IITA genotypes, and three South African genotypes were associated with high values for protein, Mn, phytic acid, molar ratios of phytic acid with Fe and Zn, and ash. The identified superior cowpea mutants, IITA and South African genotypes could be a good source of the essential minerals and should be further studied for adaptability in South African agro‐ecologies.This article is protected by copyright.
