Fusarium is one of the most dangerous of maize Pathogen that cause stalk and ear rot in addition seedling blight. Fusarium moniliforme is the must important pathogen of incidence stalk and ear rot in throughout world that cause food safety and yield loss because of its mycotoxines. As importance of maize in supply food resources of human and animal and point of view in Fusarium roul in decreasing of quality and quantity of corn, achievement 70 resistant cultivar is very important , because the most effective of way controlling has been recommended. In this study An experiment with 30 late and moderately late lines were evaluated at Karaj and Gharakhil station in 1996-1997. For inoculationg of stalk rot used tooth pick method after tasseling and for inoculation of ear rot used Nail punch method 7-10 days after silking. At physiological maturity disease severity done with scales, and the resistance of each lines determined.The results of variance analysis and mean comparison showed that no line immune to Fusarium ear rot. The realation between two disease (stalk and ear rot) is estimated (r=0/437) and emphasize to apply independent experiment for stalk and ear rot.
