Abstract	Susceptibility of winter wheat genotypes to Puccinia graminis infection was tested on experimental plots of the Plant Pathology Department, Warsaw Academy of Agriculture, in Poland during 2000-02. The evaluated wheat forms originated from the Polish breeding stations. The first infections of plants were caused by eciospores from barberry bushes and the secondary ones by urediniospores formed on leaves and sheaths of wheat. Provocative conditions during the experiments secured good development of stem rust ( Puccinia graminis ). Infection degree of comparative combination plants (wheat cv. Gama) reached the highest value. Among the 2771 tested genotypes more than 74% were severely infected by P. graminis . Genotypes free of stem rust symptoms constituted 16% of all tested forms. There was also a high percentage (74%) of very susceptible materials among winter wheat lines in the registration trials. These results show at urgent necessity of taking the stem rust into consideration in breeding work on wheat
