Research and restocking of wheat varieties to pathogens of especially dangerous fungal diseases

Based on the results of immunological assessments and rejection material by phenotype, 327 sources 79 donors immunity were selected from spring wheat, 27 23 winter respectively. Applying PCR diagnostic method, Lr genes found in samples wheat. Screening revealed presence following studied samples. They are Lr9 , Lr19 Lr24 34 Lr1 Lr10 Lr20 Lr26 . Within selection Central Russian branch, prevalence lines with gene combination inefficient was Spring soft wheat cultivation adapted to zonal conditions have been developed, combining their phenotype resistance main phytopathogens region valuable economic properties. In 2019, a variety memory Plahotnik transferred State Export Commission for testing.
