Název v původním jazyce

Virulence pattern of European bunt samples (Tilletia tritici and T. laevis) and sources of resistance

Popis výsledku v původním jazyce

In low-input conditions of winter wheat growing it is an advantage to use genetically based resistance for protection against common bunt and dwarf bunt not only for economical reasons, but also with respect to the environment. Within 3 years of field testing of samples of Tilletia laevis and T.tritici on the standard set of 14 winter wheat differential cultivars and lines (BtO-Bt13) virulence of 20 European samples, one sample from the USA and one from Syria was established. In the studied set of buntsamples virulence to the wheat resistance genes Bt1, Bt2 and Bt7 and avirulence to genes Bt3, Bt5, Bt8,Bt9, Btll, Btl2 and Btl3 most frequently occurred. The studied set represented mostly physiologic races designated as L5 or T5 (virulent to Btl, Bt2, Bt7), followed by physiologic races L3 or T3 (virulent to Btl and Bt7). Among 19 cultivars tested in field experiments as potential sources of resistance, 17 cultivars were without infection, one cultivar had only 1.5% infected spikes, one
