Winter wheat. To determine pathogenic and mutagenic properties of winter wheat viruses and possibilities of using them in breeding practice. Methods of researches are standard. Pathogenic and mutagenic properties of the most spread in the Forest-steppe Zone of Ukraine viruses of winter wheat: barley yellow dwarf virus (BYDV) and wheat streak mosaic virus (WSMV) were investigated. Results of identification, investigation of biological properties and harmful effect of BYDV and WSMV on winter wheat are presented. Induction of genetic variation by various characters in winter wheat due to viral infection was ascertained. Efficiency of mutagenic action of BYDV and WSMV was determined. Possibility of using virus-induced variability in winter wheat breeding was shown.
