%X A comparison was made between the performances of a large.plant test, the cotyledon test, and a test based on the necrotrophic reaction for assessment of the resistance-susceptibility status of various tobacco species and breeding lines to infection by Perono8pora tabacina Adam. All three methods were shown to give similar assessments and it is suggested that the necrotrophy test gives an accurate measure of intrinsic resistance.
