Abstract
In order to determine Fusarium species associated with wheat heads, 95 spike samples were collected from different geographic regions and wheat growing areas in the southwest, west, northwest and north of Iran during 2006-2008. Samples were collected from plants showing head scab symptoms. A total of 280 Fusarium strains were isolated and identified. All strains belonged to 19 Fusarium species according to morphological characters. All Fusarium strains were evaluated to test their pathogenicity on wheat which stands that F. graminearum, F. culmorum, F. crookwellense, F. trichothecioides and F. chlamydosporum were the most pathogenic to wheat’s head. This report is the first in-depth study to identify of Fusarium spp. from wheat in Iran.
