Abstract
Cowpea (Vigna unguiculata (L) Walp) is an important future opportunity crop that plays a significant role in addressing food and nutritional insecurity in tropical and sub-tropical regions of the world.
The objective of this study was to assess the nutritional and phytochemical compositions among the 15 tested cowpea genotypes to select superior potential parental lines with high nutritional and phytochemical contents for breeding for nutritional quality and anti-nutritional compositions.
Fifteen cowpea genotypes were planted at field conditions in a randomized complete block design with three replications at two different water stressed climatic zones in South Africa.
Cowpea grain samples collected from the field trials were analysed for Fe, Zn, protein, fat, flavonoids, phenolic, and condensed tannins.
The genotype-by-environment interaction effect was significant (P≤0.01) for protein content.
The significant positive correlations recorded between the essential selected mineral elements and phytochemical traits indicated that both traits could be improved simultaneously.
This finding would contribute to cowpea breeding programs targeting high nutritional value to assist with alleviating malnutrition among communities toward cheaper sources of plant-based nutrients.
