Investigation has been taken up to reveal the spore diversity of Arbuscular Mycorrhizal (AM) fungi in the soils of five different agro-climatic zones of Andhra Pradesh. Maximum AM fungal spore number was recorded in Central Telangana Zone (47) followed by North Telangana Zone (32.4) per 100g of soil. The lowest spore number was recorded in Godavari Zone (31) followed by Krishna Zone (30.6) and North Coastal Zone (30.5) of Andhra Pradesh. Spore diversity study indicated that a total of three genera with nineteen species of AM fungi were recorded in five zones of AP, of which fifteen species were of genus Glomus, three species of Acaulospora and one species of Scutellospora. The highest spore frequency was represented by G. phansihalos followed by G. fasciculatum and Scutellospora in the soils of AP. Among the five Zones spore diversity were found to be greater in Central Telangana Zone soils followed by North Telangana Zone soils. This information provides a clear direction for farmers of AP for going external inoculation of mycorrhizal fungi with the suitable genus at species level selection in each agro-climatic zone and helps in mitigating adverse environmental situations in semi-arid zones of Andhra Pradesh.
