Resistance of winter wheat cultivars to common bunt, Tilletia tritici (Bjerk.) Wint. and T. laevis Kühn

Fifteen registered winter wheat cultivars were tested for reaction to common bunt in 2-years trials. A mixture of seven Czech proveniences of common bunt was used for inoculation. Cvs Globus and Bill were most resistant in both years. The reaction of these two cultivars to 16 Czech and German samples of common bunt of different proveniences was also tested. On cvs Globus and Bill only one sample in one year caused bunt incidence 29.3% and 19.3%, whereas the incidence caused by other bunt samples was below 10% and 15%, respectively.

This paper deals with the resistance of twenty commercial winter wheat cultivars to common bunt causal agent (Tilletia tritici). Significant differences among the cultivars concerning the infection percent were observed, as well as the differences in the level of commercial cultivars' resistance to T. tritici. Most of the studied cultivars belonged to susceptible categories, and just few of them to the resistant ones. Cultivar Lasta was classified as highly resistant during the both investigation years in Kragujevac, while in Leposavic Lasta and Tiha were classified as resistant. The other studied cultivars were more or less susceptible.

The Mean

Winter wheat cultivars recently registered in the Czech Republic were tested in three-year field tests for resistance to common bunt. Seeds were inoculated with a mixture of local strains of Tilletia tritici and T. laevis. None of the cultivars displayed a higher level of resistance compared with the resistant checks. The mean percentage of bunted ears in the three test series including checks was 39%. Mean bunt infection in resistant and susceptible checks was 2% and 63%, respectively. In the European Tilletia cooperative test performed in Prague-Ruzyně, thirty-five winter wheat cultivars from six countries were tested during 2007–2013. The cultivars Bill, Nadro, Quebon, Samurai, Stava and Tommi exhibited infection levels below 10% in the respective years of the test. Additionally, 75 breeding lines from six countries were tested. Infection levels below 1% were recorded in 56% of the lines and 1–10% levels in 19% of the lines. A close relationship between the resistant cvs. Tommi and Globus was confirmed using SSR allelic markers.
