Six components of susceptibility (incubation period, latent period, pustule size, infection frequency, sporulation intensity and reaction type) were measured for seven cultivars of leek following inoculation with urediniospores of Puccinia allii. Variation among cultivars was observed for each component. Sporulation intensity, latent period, infection frequency and reaction type were correlated and appeared to be better criteria for describing variation in host response than incubation period and pustule size. Cultivars Olaf and Kajak were‘fast rusting’while cultivars Agria, Winterreuzen, Odin Longstanton, Gennevilliers Splendid and Platina exhibited varying levels of ‘slow rusting’. The ‘;slow‐rusting’ cultivars Agria and Winterreuzen are of sufficiently high agronomic quality to be worthy of consideration for commercial production.
