The present study was undertaken to evaluate the AMF association in three potato varieties Kufri Sindhuri (KS), Kufri Chipsona-3 (KC-3) and Kufri Lauvkar (KL) grown at the Central Potato Research Station, Maharajpura, Gwalior, (M.P.), India. Sampling of soil and roots was done fortnightly from sowing to harvesting. Spores were found both in the rhizospheric and bulk soils of potato varieties. The spore density was maximum in rhizosphere soil than the bulk soil. Root colonisation and spore density were observed higher in Kufri Lauvkar variety followed by Kufri Sindhuri and Kufri Chipsona-3 respectively. Following 105 days after planting, the AMF spore density in soil peaked. Spores predominantly belong to five genera of Glomus, Acaulospora, Gigaspora, Scutellospora, and Entrophospora when both the rhizo and bulk soil were mixed. Glomus sp. showed dominance in both rhizo and bulk soils, around the three potato varieties.
