A method for determining the infectiousness of a potato breeding material with an oncogenic virus involves the use of meteofactors for activation of the pathogen. The term of the activation of the pathogen is increased up to 5 days and according to the presence or absence of the outward symptoms a variety sample is divided for plants infected and uninfected with the oncovirus.
