Many populations around the world rely on indigenous plant materials as their primary source of nutrition. On the continent of Africa, many rural communities continue to gather, grow, and consume these food crops. In South Africa, there are numerous indigenous food crops, such as cereals, green vegetables, and various kinds of wild fruit. This review discusses the advantages of particular indigenous foods for nutrition and health. Current literature shows that indigenous foods possess vital macronutrients and have positive health benefits. Indigenous crops have the potential to provide options for long-term food security because they have been found to be more resistant to climate change. They might also present opportunities for new products. Literature also indicates that the benefits and value of these traditional foods are still not completely appreciated in South Africa and throughout Africa. The biggest obstacle to achieving these societal benefits is the lack of scientific information about the nutritional content, health benefits, efficient processing, and preserving technology of indigenous food. The potential value of the indigenous food system may be improved if its advantages were more properly investigated.

“…; 2 x = 2 n = 22) is an underused African legume belonging to the family Fabaceae and subfamily Faboidea (Khan et al, 2020; Olanrewaju et al, 2022). It is an annual, herbaceous and self‐pollinated plant (Bonny et al, 2019) mostly grown in the African continent (Uba et al, 2022). Bambara groundnut is a geocarpic crop, morphologically fits into the same niche as groundnut (peanut; Arachis hypogaea L.) and a close relative of cowpea ( Vigna unguiculata ) with the seed closer to chickpea ( Cicer arietinum ) based on its composition (Halimi et al, 2019; Mayes et al, 2019).…”

Understanding the phenotypic variation and designing a mini-core collection is an efficient method to accelerate the genetic gain of bambara groundnut. A collection of 300 bambara groundnut landraces from 25 different countries of origin sourced from gene banks were used to analyze phenotypic variability among the landraces and develop a mini-core collection for future breeding. The landraces were evaluated in alpha lattice design with two replications for 2 years (2019 and 2020). The results showed highly significant differences (p < 0.001) among the bambara groundnut landraces for all the studied traits implying the selection of landraces with better agronomic traits could be achieved from the crop genetic pool. In addition, landrace x year interactions were significant for studied traits, except for shelling percentage and number of seeds per pod. The genotypic coefficient of variation values were high for most yield component traits, with the highest (65.39%) value obtained on seed dry weight. Furthermore, high heritability in conjunction with high genetic advance obtained in seed dry weight, pod dry weight, petiole length and plant height implies that these traits are majorly controlled by additive genetic action and could be improved through selection. Highly significant and positive correlations of yield were found with seed dry weight, pod dry weight, number of pod per plant, number of leaves, petiole length and plant height. A mini-core collection of 60 landraces (20%) was developed that represents the entire collection using Core Hunter algorithm. In general, the study provides insight into bambara groundnut germplasm that would enhance cultivar development and sustains the utilization of the crop. In addition, the mini-core collection established in the present study could be exploited for future bambara groundnut improvement efforts.

“…There is a marked genetic variation for important agronomic traits (i.e. number of pods per plant, seeds per pod, days to maturity and yield potential) in Bambara groundnut genetic resources for pre-breeding and breeding (Beket et al 2019;Uba et al 2023). Pure line development is the common approach in strictly self-pollinating species, including Bambara groundnut until effective hybridization methods are available for hybrid breeding to exploit heterosis .…”

“…Genetically diverse Bambara groundnut collections are available in SSA for pre-breeding and breeding programs (Uba et al 2021) Well-characterised germplasm collection is a pre-requisite for plant-breeding programmes. Bonny et al(2019) reported two genetic clusters when investigating the genetic diversity among 101 Bambara groundnut accessions in Côte d'Ivoire using 13 morphological traits.…”
