Abstract
Meeting growing demand for grain requires growing high-yielding varieties that are resistant to increasing pressure from stress factors. The depletion of the gene pool of modern cereal varieties resulted in the scientists and breeders being attracted to other potential sources of resistance genes. Old varieties and local populations of cereals are one of the prospective sources of acquiring resistance genes. They are characterized by a large morphological, utilitarian and genetic diversity. The purpose of the presented works was to characterize the possibility of obtaining from local varieties and populations of local, effective and lasting sources of resistance to powdery mildew of real cereals and grasses. Using the phenotypic selection, objects characterized by a sensitivity or resistance reaction to the applied isolating isolates from different regions of the country were selected. In order to describe the differences between the examined lines / strains and the isolates of powdery mildew, statistical analyzes were carried out.
