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.
