Bambara groundnut is an essential but underutilized African annual leguminous crop, originating in northeastern Nigeria and northern Cameroon. It is cultivated in Central and West African regions for its nutritional benefits and high tolerance to drought stress. Bambara groundnut is the third most important grain legume in Africa after groundnut and cowpea. Its leaves can be used to feed livestock and traditionally cure nausea in pregnant women. Bambara groundnut's high yield under drought conditions and resistance to pests and diseases make it a valuable crop for other crops. However, the global population is projected to reach 9.7 billion by 2050, and the harvested yield from major food crops may be insufficient to meet the projected demand. Climate degradation threatens food security, with fluctuating temperatures, prolonged droughts, soil degradation, salinity, flooding, and increased disease and pest conditions disrupting major crop species' growth and performance. Exploring plant genetic diversity resources is crucial to boosting food production and supply, reducing overreliance on major food crops, and promoting global food security. However, these species often lack essential, commercially valued crops, such as high-yielding varieties. The development of underutilized crops, with their vast genetic resources and beneficial traits, can help solve food security challenges by offering a multifaceted agricultural system. Understanding the variation among traits and determining the breeding potential for agricultural improvement programs is crucial in the current context of global climate change. This review highlights the potential of Bambara groundnut, its morphological variability, and breeding potential for agricultural improvement programs
