Summaries (En, Pl, Ru) N2 - The paper contains results of 3-year experiments carried out on fertile soils in the region of frequently occurring epiphytoses Puccinia recondita, P. graminis and Septoria nodorum. These diseases are the main factor limiting grain yields. The object of studies were the following cultivars of spring wheat; Kolibri (D), Alfa (PL), Jara (CS) and the breeding strain LGR 36/11 (PL) x cv. Pembina (CDN). The yields of the studied forms corresponded to their gradually increasing field resistance to the mentioned diseases. Species differentiation in resistance to the mentioned fungal diseases suggests that this phenomenon is genetically determined T2 - Genetica Polonica.
