Funneliformis mosseae (=Glomus mosseae) is one of the most important arbuscular mycorrhizal fungi (AMF),

widely distributed throughout the world and associated with plants of different regions of the world including

rangeland. We have frequently encountered F. mosseae during our ongoing survey of AMF from rangeland plants

collected from different habitats of Saudi Arabia. As there was no systematic record of this fungus from Saudi

Arabia, so we have recorded the occu

rrence of this fungus with many different types of hosts obtained from

Arbuscular mycorrhizal fungi (AMF) regarded as ubiquitous soil fungi which help in improving plant growth under
harsh conditions. Petunia hybrida is one of the most favorite ornamental plants growing all over the Riyadh city of Saudi
Arabia. In the present study, we would like to highlight the Petunia as a mycotrophic plant for the management of
mycorrhizal fungi under field conditions. Roots along with rhizosphere soils of P. hybrida were collected from various
