Resistance to barley yellow mosaic virus (BaYMV) complex was evaluated in winter barley varieties registered in the Czech Republic, advanced lines tested in the Czech Official Trials or multilocation trials and lines developed in the Agricultural Research Institute, Kromeriz. Proportion of plants with mosaic symptoms to the total number of plants was decisive for the determination of resistance level. No Czech variety or line showed resistance to BaYMV-2. Only the variety Tokyo, registered in FRG, could be considered as resistant to the complex of three viruses. The obtained results document that the resistance to BaYMV can be increased with the use of resistant parental varieties, eg. Thalassa or Oceane from France and Jana from Germany.
