| Abstract: | The radiosensitivity of uredospores of the stem rust pathogen is studied in a wide range of β- and γ-radiations (14–2500 Gy).
It is shown that a change in the degree of infection of plants is related not to loss of virulence of the pathogen but to
their genetically determined resistance. The biochemical indices of wheat resistance to the pathogen are determined. |
