“…Bambara groundnut official descriptors have identified a number of phenotypic characteristics that have been widely documented by Aliyu and Massawe [94] and by Molosiwa et al [89]. A considerable amount of variability was observed for various phenological, physiological, and agronomic characteristics [39,51,99]. Research emphasis on the variation between and within genotypes based on morpho-physiological descriptors in the Bambara groundnut has been broadly summarized by [62,89,100].…”

“…The steady reduction in cost, along with increased access to new technology, such as next-generation sequencing, genome-wide analyses, and allelic diversity analysis of germplasm, have ushered in a new age of crop improvement. Genomic marker-based diversity-assisted plant-breeding annotations and landraces maintenance strategies have been proposed for this crop species [51,99]. Several molecular markers have been designed specifically for Bambara groundnut over the last 20 years to explore genetic variation based on phenotypic descriptors [89].…”

Bambara Groundnut (Vigna subterranea L. Verdc): A Crop for the New Millennium, Its Genetic Diversity, and Improvements to Mitigate Future Food and Nutritional Challenges

The world’s food and agricultural schemes have gradually fallen into an alarming state due to challenges such as high population birth rates, diverse agro-climatic zones, a lack of measures to counter global warming, severe practices of sole-culture cultivation, and asset reduction. A very high dependency on limited staple food crops is associated with repetitious diets, deprivation of food, and shortages of trace minerals, which often causes dietary sicknesses. To ensure nutritious diets worldwide, a real-world and justifiable scheme is provided to garner extra attention towards variation in both agriculture/farming approaches and food habits. The EAT-Lancet statement emphasized an increase in agri-based diets as a way of attaining global generational health. Enlarging neglected crops with plenty of genomic stocks and potentially profitable attributes is a solution that could address food and nutritional security concerns. Bambara groundnut is one such imperative and neglected legume crop that contributes positively to improving global food and nutrient safety. As a “complete food”, this crop has recently been treated as a new millennium crop, and furthermore, it is more adjusted to poor soil and climatic conditions than other dominant crops. Bambara groundnut is a repository of vital nutrients that provides carbohydrates, crucial amino acids, proteins, and energy as well as minerals and vitamins to developed and low-income countries where animal proteins are not readily available. This review explores the potential of Bambara groundnut in ensuring food and nutrient security; its variables, production, processing, nutrient values, role in reducing the nutritional gap, and diverse uses; and attempts in improving its traits. To strengthen food production, an agricultural revolution is required for underutilized crop species to feed the ever-expanding population in the world. Henceforth, advanced plant-breeding procedures, such as next-generation breeding techniques, various molecular tools, TILLING, Eco-TILLING, proteomics, genomics, and transcriptomics (which has been used for major crops), also need to be practiced to intensify production. To boost productivity and to feed the most starved and malnourished populations of the world, it is assumed that the application of modern techniques will play a vital role in the advancement of the underutilized Bambara groundnut.

“…Because of limited information, it is not clear whether Bambara groundnut was more common in the study areas in the past, as records suggest for fonio. Abandonment of Bambara groundnut has been documented in various parts of West Africa (northern Ghana – Abu and Buah, 2011; Berchie et al ., 2010; northern Nigeria – Tanimu and Aliyu, 1997; Cote d'Ivoire – Bonny et al ., 2019), whereas an increasing area under Bambara groundnut has been recorded for several West African countries in recent decades (FAOSTAT, 1961–2017). Berchie et al .…”

“…Berchie et al (2010) observed that the introduction of early maize varieties contributed to abandonment of Bambara groundnut in the Guinea Savannah region of Ghana. In Cote d'Ivoire, it has been abandoned as priority shifted to crops like cocoa, coffee, cashew, peanut and maize (Bonny et al, 2019). Aside from competition with other crops, challenges with drought are another factor contributing to declining use of Bambara groundnut in northern savannah areas of Ghana and Nigeria (Tanimu and Aliyu, 1997;Berchie et al, 2010).…”

Fonio (Digitaria exilis (Kippist) Stapf) and Bambara groundnut (Vigna subterranea (L.) Verdc.) are native crops grown at a small scale in Mali that have potential to support agricultural productivity under climate change. A community biodiversity management approach was explored in this study as a means to reinforce the cultivation of these crops by increasing farmers' access to intraspecific diversity and developing capacities of community institutions for their management. The research involved six communities in Ségou and Sikasso regions. Multiple varieties of fonio (10–12) and Bambara groundnut (8–12) were established in diversity fields in each site over 2 years where farmers engaged in experiential learning over the crop cycle. Significant adoption of fonio and Bambara groundnut was detected in several study sites. The precise drivers of adoption cannot be definitively determined but likely include increased seed access and awareness gained through the diversity field fora, seed fairs and community seed banks. No significant yield advantage was detected for any of the varieties in the diversity fields, which showed variable performance by site and year. The number of varieties registered and managed by community seed banks in each site increased from 1–5 varieties of each crop to 11–12 varieties following the interventions. The number of Bambara groundnut varieties cultivated in farmers' fields also increased, while there was evidence of a slight decline in fonio diversity in some communities. The results of this study can inform efforts to strengthen seed systems and cultivation of neglected and underutilized species in Africa.

Intraspecific diversity of Vigna subterranea accessions obtained from multinational sources

Bambara groundnut is a legume with balanced meal. The present study investigated agro-morphological diversity of 61 Bambara groundnut accessions whose passport data were from 21 countries. The Genetic Resources Centre (GRC), International Institute of Tropical Agriculture (IITA), Ibadan, Nigeria provided the 61 accessions. The accessions were established in row plots of ten plants on the field at the Centre for Ecological studies, University of Port Harcourt, Nigeria. Seventeen quantitative and two qualitative traits were recorded from the sampling units for each accession. Descriptive and multivariate statistical analysis were employed on the 61 x 19 matrix mean data. Significant variation exists among the 61 accessions for the 19 descriptors. Mean genetic similarity among the 61 accessions was 0.78, the least (0.48) similarity was between TVSu1750 and TVSu250 and the highest (0.92) was between TVSu391 and TVSu415. TVSu1843 flowered earliest at 35 days. The 61 accessions were grouped into three main clusters. TVSu1964 and two accessions from Malawi (TVSu1748 and TVSu1750) in cluster III had high grain yield. Accessions in cluster II were significant for both vigour and grain yield. Striking uniformity and diversity existed among accessions from the same country. Genetic improvement in vigour and grain yield of Bambara groundnut is possible within each country.
