MONITORING OF SPECIES COMPOSITION OF FUNGI OF THE GENUS FUSARIUM IN SEED MATERIALS OF WINTER WHEAT ON UKRAINIAN TERRITORY

Abstract

Aim. To investigate strain composition of fungi of the genus Fusarium in winter wheat grain in Ukraine. Methods. Contamination of wheat grains with fungi was detected during their sprouting in rolls of filter paper. Molecular diagnostics of strain composition was performed with the use of commercial test-systems. Results. The analysis of 109 seed samples of winter wheat from 21 regions of Ukraine was conducted. Virtually in all regions of the cultivation of grain crops in Ukraine, grains are affected by fungi of the genus Fusarium. The greatest number of affected samples of wheat was revealed on the territory of western and central regions. The prevail species in the complex of the genus Fusarium were F. graminearum, F. sporotrichioides and F. avenaceum. Conclusions. The high level of the wheat grain infection with causative agents of fusariosis necessitates annual monitoring of this phytosanitary index on the territory of Ukraine.
