The centre of origin of Bambara groundnut (BGN; Vigna subterranea L.) is Western Sub-Saharan Africa. Due to its high nutritional value and tolerance to biotic and abiotic stresses,
this neglected and underutilised species has recently gained significant attention. However, BGN production faces several challenges, including a lack of quality varieties. This study describes a selected core collection based on phenotypic traits, investigates relevant selection criteria and identifies a set of landraces according to participants’ preferences. A core collection of landraces was generated, described, and then subjected to participatory varietal selection. Through individual semi-structured interviews, key selection criteria were identified. Focus group discussions were organised to explore group criteria and to support and validate information from personal interviews. The varietal selection involved choosing three landraces per participant. The results highlighted that seed colour, seed size, cultural value, market value, seed taste, storage, and seed cooking duration were the main selection criteria; however, specific trait preferences varied by gender and participants. Two of 14 selected BGN landraces were considered by the panel of evaluators to be most suitable for recommendation to growers and breeders. They can be disseminated in BGN production regions and used for plant breeding.
