Thirty‐one accessions of four Lactuca species ( L. serriola, L. saligna, L. aculeata, L. squarrosa ) and one L. serriola × L. sativa hybrid were screened for field resistance to Bremia lactucae. In the L. serriola group, significant differences in the level of field resistance were distinguished. The accessions PI 281876 and PI 253467 were free of infection. Moreover, all L. saligna accessions tested were totally free from disease during three‐year‐investigation.
