Abstract

Fusarium species are one of the most studied pathogenic fungi, with several species causing diseases on plants, animals and human. In many agricultural crops this genus leads to decreased yield and diminished quality. Cereals especially wheat are the most important crops in Iran and many of Asian countries which every year root disease as a severe problem, cause economic damages to this crop. So identification and then proper management of this disease will be helpful to reduce economic losses. During a survey in 2015–2016 for Fusarium species from poaceae family in western Iran, based on morphological method, a total of 150 isolates were selected to identification and finally 15 species were determined. DNA sequence data also have been used to aid in distinguishing probable species. Sequence analyses of the internal transcribed spacer (ITS) region revealed three new species from Iran flora; F. concentricum, F. falciforme, and F. torulosum.
