"Powdery mildew caused by Blumeria graminis f. sp. hordei fungus induces 50 % of all epidemics on spring barley in the Czech Republic. Growing resistant cultivars is a cheap, efficient and health safe way of reducing harmfulness of this disease. Breeding spring barley cultivars resistant to powdery mildew is supported by a large number of known resistance sources. However, practical durability of each resistance is limited by adaptability of the pathogen population. One of the adaptation mechanisms is recombination. The air pathogen population sampled in the territory of the Czech Republic was investigated in 2001. Virulence spectra of isolates were determined using infection types produced by these isolates on leaf segments of 12 differential barley cultivars possessing different resistance genes to powdery mildew." . .
