Common smut is one of the most prevalent fungal diseases of maize which causes high qualitative and quantitative losses on yield. One of the best controlling methods of the disease is use of resistant hybrids. In order to evaluate the resistance of 18 early maize genotypes, an experiment was carried out in RCBD with two replications at Karaj, Isfahan, and Mashhad. Inoculation of the ears was done by syrange (3ml spore/ear) at silking stage. Disease severity on ears was assessed 3-4 weeks after appearance of the first disease symptoms. The results of combined analysis of variance and mean comparison showed differences in disease severity among examined materials. Based on disease severity (0-7), the responses of genotypes were ranked in five groups (highly resistance to highly susceptible). Line KE 72012/12 was highly resistant and OH43/1-42 susceptible. K 1264/5-1 K 615/1 and KE 72011/1
K 1264/5-1 were susceptible and resistant hybrids, respectively.
