SUMMARY Seedling leaves, flag leaves, culms and heads of wheat genotypes were evaluated under glasshouse and field conditions for reaction to Septoria tritici. Parameters used for resistance screening were the incubation and latent periods, disease and sporulation levels, and 1000 grain weight. Significant correlations were obtained between reactions of different plant organs and between field and glasshouse tests; significant interspecific and intraspecific differences occurred for all screening parameters. Triticum aestivum varieties showed a wide range of disease reaction ranging from the high resistance of Elite Lepeuple, Maris Dove, Maris Ensign, Chalk and Tommy to the high susceptibility of Rothwell Sprite, Sovereign, Cardinal, Maris Ranger and Maris Templar.
