An ecogeographic study African vigna por Maxted, N., Mabuza-Diamini, P., Moss, H., Padulosi, S., Jarvis, A., Guarino, Luigi

“…It is suggested that: in situ genetic reserves are established within existing protected areas at the southern tip of Lake Tanganyika, in the coastal area of Sierra Leone and between Lake Victoria and the other Great Lakes; there is a need to establish patterns of genetic diversity in landraces of V. subterranea and V. unguiculata before in situ on-farm conservation can be proposed; and further germplasm collection and ex situ conservation are particularly required in Cameroon, the Democratic Republic of the Congo, Guinea Bissau, Nigeria and Zambia and V. dolomitica, V. haumaniana var. pedunculata, V. monantha, V. nuda, V. richardsiae, V. somaliensis, V. stenophylla, V. subterranea var. spontanea, V. unguiculata subsp. unguiculata var. spontanea, V. unguiculata subsp. aduensis, V. unguiculata subsp. baoulensis, V. unguiculata subsp. burundiensis, V. vexillata var. dolichonema and V. virescens are the highest priority species. …”
