SUMMARY Three clones of potatoes bred from Solanum vernei were tested for their resistance to the white potato cyst‐nematode, Heterodera pallida , both by root‐ball counts and by estimates of total cysts produced. Two susceptible clones were used as controls. Root‐ball counts suggested a higher degree of resistance than that based on total cysts produced. There were differences in pathogenicity between the two populations. The degree of resistance found was such that in practice the resistant clones would be best used in conjunction with nematicide treatment in a system of integrated control.
