“…The SARI in Ghana holds 16 accessions, collected in Ghana. However, efforts are still required when compared to the genetic resources accessible ex-situ for most of the other legume crops like Bambara groundnut (Massawe et al, 2005(Massawe et al, , 2007Aliyu et al, 2016;Mayes et al, 2019), chickpea (Raina et al, 2019;Jha et al, 2020;Kushwah et al, 2020), horse gram (Singh et al, 2014;Chahota et al, 2020), mungbean [Vigna radiata (L.)

Kersting's groundnut [Macrotyloma geocarpum (Harms.) Maréchal and Baudet], Fabaceae, is an important source of protein and essential amino acids. As a grain legume species, it also contributes to improving soil fertility through symbiotic nitrogen fixation. However, the crop is characterized by a relatively low yield (≤500 kg/ha), and limited progress has been made so far, toward the development of high-yielding cultivars that can enhance and sustain its productivity. Recently, there was an increased interest in alleviating the burdens related to Kersting's groundnut (KG) cultivation through the development of improved varieties. Preliminary investigations assembled germplasms from various producing countries. In-depth ethnobotanical studies and insightful investigation on the reproductive biology of the species were undertaken alongside morphological, biochemical, and molecular characterizations. Those studies revealed a narrow genetic base for KG. In addition, the self-pollinating nature of its flowers prevents cross-hybridization and represents a major barrier limiting the broadening of the genetic basis. Therefore, the development of a research pipeline to address the bottlenecks specific to KG is a prerequisite for the successful expansion of the crop. In this paper, we offer an overview of the current state of research on KG and pinpoint the knowledge gaps; we defined and discussed the main steps of breeding for KG' cultivars development; this included (i) developing an integrated genebank, inclusive germplasm, and seed system management; (ii) assessing end-users preferences and possibility for industrial exploitation of the crop; (iii) identifying biotic and abiotic stressors and the genetic control of responsive traits to those factors; (iv) overcoming the cross-pollination challenges in KG to propel the development of hybrids; (v) developing new approaches to create variability and setting adequate cultivars and breeding approaches; (vi) karyotyping and draft genome analysis to accelerate cultivars development and increase genetic gains; and (vii) evaluating the adaptability and stability of cultivars across various ecological regions.

“…Previous research has shown that M. uniflorum seed is a fine source of amino acids, protein, carbohydrates, low lipid, iron and molybdenum (Bhaskar et al, 2019). It also contains slow metabolizable carbohydrate (starch), which has a reduced postprandial blood glucose reaction while ingested by diabetics (Chahota et al, 2020). Furthermore, a solvent extract of horse gram plants has been reported as hypolipidemic activity in lab animals fed a elevated fat diet (Kumar et al, 2013).…”

“…The extract administered to rabbits with oxidative stress caused by an elevated fat diet resulted in an increase in superoxide dismutase (SOD) as well as catalase (CAT), as well as an increase in lowered glutathione (GSH) accumulation (Jarukamjorn et al, 2016). Such horse gram has been consumed by a massive population in rural areas of southern India as a whole seed sprouts (Chahota et al, 2020). Notwithstanding, consuming horse gram seeds upon having to process including heating accompanied by preparing meals, together with boiled rice, millet, and sorghum is indeed a most common practise in rural Indians (Platel and Srinivasan, 2016).…”

The Macrotyloma uniflorum seed (Horse gram) has been underutilized pulse around the world. Nevertheless, it contains most valuable nutritional and pharmacological phytochemicals. Thus, this research was performed to evaluate the antioxidant, anticancer, and hepatoprotective potential of horse gram methanol extract. Interestingly, methanol extract of horse gram demonstrated dose dependent antioxidant, anticancer, and hepatoprotective activities. Since, at increased (100 mg mL-1) concentration the methanolic extract scavenged the DPPH radical up to 93.5% and reduced the ferric (Fe3+) into ferrous (Fe2+) up to 95%. Similarly, the methanol extract also possess considerable anticancer activities up to 75.64% at 300 mg mL-1 concentration. Furthermore, at increased concentration (300 mg mL-1), the methanol extract effectively protect (hepatoprotective) the HEK293 cells (95.71%), which exposed to 100 mM glucose (hepatotoxicity). The obtained results conclude that the horse gram methanol extract contains pharmacologically valuable phytochemicals and that regular intake of horse gram can be recommended to improve human health
