Abstract: Resistance to common bunt and to dwarf bunt in winter wheat cultivars recently registered in the Czech Republic was studied in artificially inoculated field trials in the years 2013-2015. In trials with common bunt, seeds of each experimental series were inoculated with a different mixture of isolates. In dwarf bunt trials, the soil surface was inoculated with a natural bunt population from a single locality. Several selected unregistered wheat cultivars, triticale cultivars and cultivars/lines known as sources of dwarf bunt resistance were also included in the trials with dwarf bunt. Out of the recently registered winter wheat cultivars only cv. Genius showed resistance to common bunt in both test years. Cv. Sailor was highly resistant to common bunt only in one trial, but not in other trials with different inoculum. Cv. Saturnus and the registered cv. Potenzial showed the lowest incidence of dwarf bunt in both years. The triticale cultivars were highly resistant to dwarf bunt compared to the wheat cultivars used as checks. High resistance to dwarf bunt in the tested sources of resistance was confirmed.
