Exploitation of detected BYDV resistance genes in barley breeding

Original language description

The resistance to Barley yellow dwarf virus (BYDV) of barley cultivars, breeding lines, and resistance sources from world collections has been tested in RICP Prague-Ruzyne over the past 10 years. Most barley materials were found to be susceptible or moderately susceptible to BYDV. High resistance levels were associated with the presence of the Yd2 gene, but other genes non-allelic to Yd2 were also detected in moderately resistant spring and winter barley cultivars. Significant levels of resistance to BYDV were obtained in spring barley by combining Yd2 with genes detected in moderately resistant cultivars. The effect of Yd2 on barley quality traits was examined using different sets of double haploid (DH) lines and recombinant inbred lines (RILs). Analysis showed that the presence of the Yd2 gene did not affect malting quality traits or other important agronomic characters tested. The effect of the genetic background on Yd2 efficiency was investigated and found to be rather high, especi
