The use of germplasm resistant to BYDV is generally regarded as the most effective means of controlling damage caused by this pathogen. Effective sources of resistance have been detected in both the spring and winter barley cultivars, but pyramiding resistance genes are necessary for increasing the resistance level. Studies of genetic diversity of resistance and effects of genetic background on gene expression are important from breeding aspects. There is now at disposal PCR diagnostic marker of BYDV resistance gene Yd2, used in RICP Prague successfully in spring barley. It is however necessary to develop markers for resistance genes detected in winter barley and markers of genes conferring moderate resistance in the registered cultivars Malvaz and Atribut.
