Summary
Thirty-six cultivars described as resistant or partially resistant by various authors were tested for reaction to a mixture of Tilletia tritici (race T-l) and Tilletia laevis (race L-5). No infection was found in cvs. Amigo, Crest, Franklin, Stava and Tjelvar, low infection (0,9–9,1 %) in Cardon, Wasatch, Hildebrands Weissweizen B, Shekhurdinovka, Nebred and Dobrovická přesívka. In other trials separate inoculation with T tritici and T. laevis was carried out. None of the cultivars registered at present in the Czech Republic and of the advanced lines in the State Varietal Trial was resistant to Tilletia laevis (race L-5); only advanced line HE-3625 was resistant to T tritici (race T-1). None of the foreign cultivars tested in the State Varietal Trial was resistant to T laevis (race L-5); only cvs. Bussard and Euris showed less than 5 % of infection with T. tritici (race T-1).
The following were resistant to both inocula: lines/cvs. with resistance genes Bt3, Bt4, Bt5, Bt6, Bt8, Bt9, Bt10, Bt11, Bt12, Bt13 and the sources of resistance PI 560795 SEL.BCO, PI 560841 SEL. WCO, PI 560 841 SEL.BCL. Breeding for resistance to bunt is discussed.
