Arbuscular Mycorrhizal Fungi make (AMF) a symbiotic association with almost 80% of the land plants. The fungi improve the nutrients uptake ability of the plant root specially PO₄ through its extended extrametrical hyphae beyond the root zone. Recent studies showed that not only through extrametrical hyphae of the fungi but also it changes the branching pattern and root architecture of the plant root at the very early stage of fungal colonization area to increase the overall root surface area. Upon AMF inoculation it was raveled that increase in number and length of root branching (absorptive root) found in both AMF responsive and no or low responsive rice variety. However, the level of increase is 2–2.5 times higher in AMF responsive variety. One AMF responsive variety-MTU 7029 and other AMF low responsive variety-ARC 12737 were inoculated with root based mixed inoculums having propagule count……/gm with control pot for the experiment. The total roots were harvested at 15 days after germination and examined for root morphological studies. The result showed that in both the variety changes in seminal root number and length is negligible where as the lateral root branching number and length increases significantly over control.
