ABSTRACT: Arbuscular Mycorrhizal Fungi (AMFs) could be used to
sustainably improve crop yields. The present study evaluated the diversity of
AMF species associated with soybean (Glycine max L. Merill) in main soybean-producing areas in Benin. Composite
soil samples from 13 production areas at a rate of 04 villages per production
areas were collected. A spore trapping device was set up to reveal the
diversity of spores. The physical and chemical properties of the soils, the
frequency and intensity of mycorrhization of roots, and the diversity of AMF
spores were determined in the soil samples following trapping. As result, eight morphotypes
belonging to four genera: Glomus, Acaulospora Gigaspora and Disversispora and three families: Diversisporales, Glomérales and Paraglomérales were observed. An important
variability of spore densities was observed from one production areas to
another with a higher abundance in the production areas of Copargo estimated at
3584 spores/100g soil. The biological diversity indexes as Shannon (0.0311),
Simpson (0.0204) and Hill (0.0235), varied significantly (p
