“…Henceforth, these current ndings also con rmed the e ciency of ISSR primers to discriminate among the populations that are distinct, similar, or closely associated. Our ndings have reliable evidence with the result of Rungnoi et al (2012) reported Nei's genetic distances among the populations of 14 countries using ISSR and RAPD; Nilkanta et al (2017) using ISSR, Mohammed et al (2019) stated genetic distances of 50 Bambara groundnut varied from 0.0 to 3.8 using SSR, A similar extent of variation among the populations was reported in the previous study that related to our current genetic analysis. Massawe et al (2003) found an identical trend of association in the Bambara groundnut diversity study using RAPD and suggested that such nature of association among the landraces indicating the genotypes were genetically identical.…”

“…2010) whereas 0.38-1.6 t ha − 1 reported by Khan et al (2020) by ensuring the optimal growing environment. The main point of low yield of Bambara groundnut is the use of local land races in addition to little or no attention to genetic improvement, lack of improving varieties with production technologies, lack of effective research and resources, less research interest by scienti c personals (Mohammed et al 2019). The autogamous and cleistogamous nature of Bambara groundnut is the major hindrance of its varietal development through hybridization (Molosiwa et al 2015).…”

The researchers Molosiwa et al (2015), Mohammed et al (2019), SiiseAliyu and Massawe (2013), and Odongo et al (2015) reported genetic diversity has existed in the evaluated genotypes of Bambara groundnut applying SSR markers because of their duplicability, co-dominant nature, and richness in the genome. In literature, negligible evidence was found related to the use of ISSRs marker in Bambara groundnut.…”

Background A set of 44 selected Bambara groundnut (Vigna subterranea L. Verdc.) accessions was sampled from 11 distinct populations of four geographical zones to assess the genetic drift, population structure, phylogenetic relationship, and genetic differentiation linked with ISSR primers. In Malaysia, this is an exotic legume introduced from Africa and having tremendous nutritional values and diverse usages. Methods and Results The amplification of genomic DNA with 32 ISSR markers detected an average of 97.64% polymorphism while 35.15% and 51.08% polymorphism per population and geographical zone, respectively. Genetic diversity estimated by Shannon’s information index (I) = 0.177 (average) and populations under Gombe showed maximum diversity (I = 0.271) with 90.98% polymorphism. Analysis of molecular variance revealed significant variation within population 75% and between population 25% whereas within region 84% and between region 16%. The study also divulged total genetic variation Ht = 0.1781 closer to within population diversity (Hs = 0.1155). Among the population, Cancaraki revealed 40.39% polymorphism while the average polymorphism was 35.15%. The Bidillali exposed greater number of locally common band i.e., NLCB (≤ 25%) = 25 and NLCB (≤ 50%) = 115 were shown by Cancaraki while the lowest was recorded as NLCB (≤ 25%) = 6 and NLCB (≤ 50%) = 72 for Roko and Maibergo, accordingly. The highest PhiPT value was noted between Roko and Katawa (0.405*) whereas Nei’s genetic distance was maximum between Roko and Karu (0.124). The genetic differentiation among population Gst = 0.3514 (35.14%) leaving 65.86% of genetic variation leads to within-population with gene flow of Nm = 0.9229. Based on Nei’s genetic distance, a radial phylogenetic tree was constructed that assembled the entire accessions into 3 major clusters for further confirmation unrooted NJ vs NNet split tree analysis based on uncorrected P distance exposed the similar result. Principal coordinate analysis showed variation as PC1 (15.04%) > PC2 (5.81%). Mantel test exposed a significant correlation among genetic and geographic distance of accessions. STRUCTURE analysis (Bayesian) grouped the accessions into 3 major genetic components based on best ΔK = 3 and admixture population. Conclusions The current study leads to prompting the genetic improvement and future breeding program by maximum utilization and better conservation of existing V. subterranea accessions in this subtropical environment.

Background: Bambara groundnut has promising economic potential due to its various uses such as food, medicinal and agronomic benefits. To date, there are no significant breeding efforts aimed at cultivar development and the crop remains underutilised.Aim: To characterise and identify Bambara groundnut landraces using agro-morphological and chlorophyll traits to identify breeding lines for cultivar development.Setting: The experiment was conducted in Limpopo and North West provinces (Loskop and Molelwane research farms).Methods: This study used randomised complete block design (RCBD) with three replications.Results: Analysis of variance revealed significant variations among most of the landraces used. Highly significant positive correlations were observed for most of the traits recorded. The principal component analysis (PCA) indicated that the first six principal components contributed 78.34% of the total variability among the test genotypes that were being evaluated. The biplot and dendrogram further grouped the landraces according to traits associated with them. Shannon Weaver’s diversity index showed a wide variability among the accessions in qualitative morphological traits.Conclusion: The agro-morphological traits and chlorophyll content characterisation showed significant variability within the landraces tested. These findings would be beneficial for breeders to choose the desirable traits associated with the Bambara groundnut landraces in the breeding programme for the development of new breeding population.Contribution: The identified superior landraces will be utilised by the small-scale and large-scale commercial farmers for direct cultivation and marketing, and can be used as parents in breeding programmes.

“…Bambara groundnut, a drought‐tolerant pulse grain of African origin with 19%–25% protein (Mohammed et al ., 2023), can be a potential replacement for soybean and pea protein. Bambara groundnut protein is rich in essential amino acids such as lysine, particularly methionine (1.62 g/100 g) (Alabi et al ., 2020), which is limited in most legumes including soybean.…”

SummaryThe gel‐forming ability of the pulse proteins influences the formation of food products with desirable texture, structure, and stability. In this study, Bambara globulin was fractionated into legumin and vicilin for structural and physicochemical analyses, and heat‐induced gel rheological characterisation. Bambara globulin showed major vicilin (7S, Mw: 120 kDa) and minor legumin (11S, Mw: 410 kDa) components by size exclusion chromatography and gel electrophoresis analyses. Legumin had the lowest amount of all the charged amino acids. One basic subunit (22 kDa) was identified in the legumin fraction with predominant helical structures. The sol–gel transition temperatures increased in the order of globulin (40 °C) < legumin (50 °C) < vicilin (80 °C). The G′ and G″ of globulin showed relatively low dependency on heating time beyond the gel point compared to legumin and vicilin subfractions, suggesting a more rapid establishment of its gel network during gelation. Vicilin gel consisted of a microporous structure with a small lath sheet‐like structure compared to others. Bambara vicilin could be a prospective ingredient in the development of new products with defined textural characteristics.
