Today the use of chemical fertilizers to the problems of society has imposed. However, the important role of biological fertilizer in the food plants supply and reduce the environmental impact has been proved. Considering that, one the goals of producing is access to healthy seed and seed quality and high production capacity, in order to examine the effects of biological fertilizer mycorrhizal on the properties of corn seed varieties, the experiment was a factorial based on a randomized complete block design with four replications that was carried out at the Agricultural Research Station, Zahak, Zabol, Iran in 2010. The experiment consisted of two factors, the first was seed inoculation with fungal species of Glomus mossea mycorrhiza and no inoculation; and the second was four varieties of corn named: SC-770, Tisa, SC-7020 and SC- 704. The results showed that application of biological fertilizer mycorrhizal had a significant effect on plant height, flag leaf width, number of grains per ear, 100 seed weight and yield seed (p≤ 1%) and flag leaf length (p≤ 5%). Interaction effects of mycorrhiza × varieties was not significant except for 100 seed weight (p≤ 1%), plant height and yield seed (p≤ 5%).
