“…Tamini [14] reported the White mottled with black eye and the Black landraces in Burkina Faso; whereas in this study, a White landrace was additionally recorded and collected. Similarly, the Brown and the White mottled with greyed orange eye were found only in Ghana and were not yet reported by previous investigations [17,35]. In this study, we therefore found additional diversity in the southern-Sudanian zone of Burkina Faso and Ghana.…”

“…This was true for Kersting's groundnut in the farming systems of Burkina Faso and Ghana. However, in other communities, men were mostly involved in the crop production as the crop certainly exhibits a high economical value in those communities [12,17]. The economical and the nutritional importance of this crop should be clearly highlighted and promoted across its production areas in order to better use the genetic resources available for food and nutrition security as well as for income generation.…”

Pulses play important roles in providing proteins and essential amino-acids, and contribute to soils' nutrients cycling in most smallholder farming systems in Sub-Saharan Africa (SSA). These crops can be promoted to meet food and nutrition security goals in low-income countries. Here, we investigated the status of Kersting's groundnut (Macrotyloma geocarpum, Fabaceae), a neglected pulse in West Africa. We explored its diversity, the production systems, the production constraints and farmers' preferences in Burkina Faso and Ghana. Focus groups and semi-structured interviews were conducted in 39 villages with 86 respondents grouped in five sociolinguistic groups. Our results indicated that Macrotyloma geocarpum was produced in three cultivation systems: in the first system, farmers grew Kersting's groundnut in fields, mostly on mounds or on ridges; in the second system, farmers grew it as field border; and in the third system, no clear tillage practice was identified. The main constraints of those farming systems included: difficulty to harvest, the lack of manpower and the damage due to high soil humidity at the reproductive stage. A total of 62 samples were collected and clustered in six landraces based on seed coat colors including cream, white mottled with black eye, white mottled with greyed orange eye, black, brown mottled, and brown. All six groups were found in the southern-Sudanian zone whereas only white mottled with black eye and black colors were found in the northern-Sudanian zone. The white mottled with black eye landrace was commonly known and widely grown by farmers. Farmers' preferences were, however, influenced by sociolinguistic membership and the most preferred traits included high yielding, drought tolerance, and resistance against beetles. These findings offer an avenue to develop a relevant breeding research agenda for promoting Kersting's groundnut in Burkina Faso and Ghana.

“…The low yield of Kersting's groundnut as for many other crops in sub-Saharan Africa is due to poor agronomic management and lack of improved varieties [29]. The use of Bradyrhizobium CB 756, a rhizobium strain, was proven to be able to induce nodulation in Kersting's groundnut [82].…”

“…As the other legume crops, Kersting's groundnut is a source of relatively cheap protein for rural populations [26]. Despite its nutritional attributes and its ability to adapt to marginal area, the crop still remains underexploited grain legume [14,24,27,28] and characterized by low yield due to poor agronomic management and lack of improved varieties [29]. It is worth noting that Kersting's groundnut is highly region specific as its cultivation is confined to West Africa [30], an additional fact that may justify its neglected status.…”

Kersting's groundnut is a tropical crop, highly nutritious, adapted to drought-prone areas. The crop is neglected both by researchers and by policy makers. This paper aimed at providing relevant information on the current status of the crop and the prospects to promote its improvement and production. To this end, available papers addressing any of the following aspect: distribution, nutritional value, cropping systems, post-harvest processing, usages, value chains, conservation status, genetic diversity and improvement of Kersting's groundnut were reviewed. In West Africa, the crop provides substantial income for rural population. Kersting's groundnut has several medicinal uses and cultural values as well. However, because of its intensive labor requirement, low yield and non-availability of improved varieties, its cultivation is declining and it is even disappearing gradually in some growing areas. The promotion of the crop's value chains is an option for reversing the declining trend in Kersting's groundnut cultivation. In recent years, some progress has been recorded in the collection, characterization and ex situ conservation of the crop. Thus, there are currently about 100 accessions conserved in various gene banks in Benin, Ghana, France and Belgium. This is still insufficient as compared to the genetic resources available in ex situ for most of the grown legume crops. To cope with this, extensive germplasm collection and their systematic characterization and evaluation coupled with new generation genomic tools need to be undertaken. For this purpose, genomic resources developed for Kersting's groundnut-related species will be valuable assets. The exploitation of genomic resources will enable the development of core and mini-core collections for conservation and breeding purposes. In addition, the use of genomic resources will speed up Kersting's groundnut breeding programs. Furthermore, the genetic base of the crop is extremely narrow and there is a need to broaden it for substantial genetic gain in breeding programs. For this purpose, mutation induction has been proposed as technique to increase variability in the Kersting's groundnut germplasm. Invest in Kersting's groundnut research is key to ensure the conservation and exploit the potential of the crop.

Understanding genotype by environment interaction (GEI) represents a challenge in Kersting's groundnut [Macrotyloma geocarpum (Harms) Maréchal and Baudet] breeding for selecting high‐performing and stable lines across environments. Here, we investigated GEI and stability in Kersting's groundnut using factor analytic (FA) based linear mixed models and environmental covariates. A total of 375 accessions were evaluated across 3 years (2017, 2018, and 2019) and two locations (Sékou and Savè) in Benin, generating five environments (E1, E2, E3, E4, and E5). The traits measured included days to 50% flowering (DFF), grain yield (YLD), and 100‐seed weight (HSW). The study generated multi‐environment values for grain yield and its components in Kersting's groundnut. The genetic correlations between pairs of environments ranged from −0.71 to 0.99. The genetic correlations between YLD and HSW indicated positive and moderate to high correlations in all environments. The FA analysis revealed that FA2 structure accounted for 93.9% of the genetic variability in DFF with factor 1 accounting for more than 90% of the environments variations. Two factors explained 87% of the genetic variance in grain yield, and 70% of the environments variability were clustered by factor 1. For HSW, two factors explained 85% of the genetic variance of the environments, and factor 1 accounted for 72.7%. Combining environmental covariates to FA models revealed that precipitation, temperature, and growth cycle duration were highly correlated to the environmental loadings of factor 1. Relative humidity and solar radiation showed moderate to high correlations with factor 2 loadings. Those covariates explained the high GEI among environments clustered by a given factor. Precipitations and temperatures affected the variations in grain yield. Finally, based on latent regression analysis, the accessions AF202, AF221, AF223, AF225, and AF256 were identified as accessions combining best performance for grain yield, early flowering, and 100‐seed weight, showing adaptability across environments and stability to some environments.
