SUMMARY The resistance to Globodera pallida of potatoes bred from Solanum uernei was assessed rapidly in pot tests by counting cysts on the exterior of the root ball. Assessments of resistance made in this way in three consecutive years were reproducible on a ranking basis. There was also a significant agreement in the ranked results of pot and field tests. A more accurate assessment of nematode multiplication rates in the field could be provided by laboratory tests in which temperature, moisture and initial nematode numbers were strictly controlled.
