Potato is one of the most productive crops in agriculture and is a valuable food source in developing countries. Mycorrhizal fungi involve a symbiosis with most of crop roots and leads to improve the crops growth and yield. In order to investigate the effect of mycorrhiza fungi species on yield of potato cultivars a factorial experiment was arranged in a randomized complete block design with eight treatments (seven mycorrhiza fungi species and control treatment) on two potato cultivars, Agria and Fontane, in three repetitions. Results show that there is no significant difference in tuber yield and shoot P content in Agria and Fontane, but leaf area and shoot dry weight and total tubers weight in Fontane were higher than Agria. Control treatment and A. longula had the least and G. mosseae، G.intraradices and G. versiform had the highest tuber weights. Among fungi G. mosseae produced the highest tuber yield in both cutivars. Inoculation of root medium with G. versiform produced the highest average tubers weight compared to other treatments. Phosphorus content of treated plants with mycorrhiza was higher than control.
