Isolation and characterization of fungal strains from the seeds of Bambara groundnut (Vigna subterranea (L.) Verdcourt) produced in Burkina Faso

Bambara groundnut is the main food legume after cowpea, especially in rural areas Burkina Faso. Due to inappropriate production and storage conditions, seeds are susceptible contamination by several fungi. Therefore, present study was conducted isolate identify postharvest fungi associated with produced To do this, a total of 99 seed samples were collected three agro ecological zones The sanitary analysis carried out using blotting paper method slight modifications. isolation purification isolates performed on Potato Dextrose Agar medium while their identification done through macroscopic microscopic phenotypical characterization different culture media (Malt Extract Czapeck Dox Agar) keys. A 421 fungal strains isolated predominant genera Aspergillus belonging section flavi (66.84%), nigri (59.04%), Macrophomina (26.49%). This shows that Faso contaminated infection rates these differ according agro-ecological zones. Post-harvest techniques need be improved limit crop losses.   Key words: Agro-ecological zone, groundnut, seeds, strains, characteristics,
