Description	Fifty-five isolates of Rhynchosporium secalis from Hordeum vulgare and 34 isolates from Secale cereale were compared for growth on different nutrient media, effect of temperature on growth and morphology of colonies. The pathogenicity of the isolates was assessed on 10 rye varieties, 10 triticale varieties and the susceptible barley variety Gambrinus. The triticale varieties differed in the number of rye chromosomes in the genome. Isozymes of R. secalis isolated from infected leaves of barley and rye were compared. The RAPD-PCR method was used for comparison of isolates on DNA-markers. The analysis indicated two specialised forms of the fungus; each of them able to develop only on its original host.

(en) Byl porovnán růst na různých živných půdách a vliv teploty na morfologii kolonií 55 izolátů houby Rhynchosporium secalis, pocházejících z ječmene a 34 izolátů původem z žita. Patogenita izolátů byla zjišťována na 10 odrůdách žita, 10 odrůdách tritikále a náchylné odrůdě ječmene Cambrinus. Tritikále se lišily v počtu obsažených žitných chromozomů v genomu. Byly porovnány isozymy izolátů R. secalis původem z žita a ječmene za použití DNA- márkrů při RAPD-PCR. Výsledky indikují existenci dvou specializovaných forem houby, z nichž každá se vyvíjí pouze na původním hostitelském druhu. (cs)
