The reactions of 146 potato varieties to graft infection with viruses X, A, B and C are recorded, on the basis of their top‐necrotic or non‐necrotic symptoms. Evidence is given that the viruses B and C used in this work were uncontaminated with other viruses. Reference is made to the effects of varietal reaction on virus distribution.
