The purpose of the work is to identify and study particular biological characteristics of the genus Fusarium isolates, received from the Triticum aestivum L grain. Methods. In this paper, the cultural and morphological properties of investigating isolates of micellar fungi are studied in order to identify them to species further. For the detailed characteristics of the isolates, the speed of radial growth of the mycelium and the intensity of spore formation are also determined. Results. Based on the studied cultural and morphological features, isolates are classified into species F. graminearum and F. oxysporum. The isolate F. graminearum KMA-1 is characterized by the highest coefficient of radial growth rate, whereas the highest intensity of spore formation is detected in F. oxysporum KMA-7. It has also been found that the chemical composition of the media does not affect, compared with F. graminearum strains, the growth rate of the isolate F. oxysporum KMA-7. Conclusions. The biological features of F. graminearum KMA-1 and F. oxysporum KMA-7, isolated from a grain of Triticum aestivum L. have been studie. It allows us to predict their high competitive ability, among other investigated strains, which is due to the apparent strategy of wheat colonization in agrocenosis.
