Abstract
A total of 67 barley cultivars and breeding lines were tested for leaf rust resistance were tested with eight differential isolates. These isolates originated from IHAR Radzikow collection and were chosen according to their virulence spectra. Among 67 cultivars and breeding lines 41 (61%) showed resistance reaction after inoculation with at least one isolate of leaf rust. In 29 cultivars and breeding lines (43.2%) the presence of specific resistance alleles was postulated. For most tested cultivars and breeding lines (56.8%) it was impossible to postulate the presence of the specific resistance alleles. Twenty six (38.8%) cultivars and breeding lines showed susceptible reaction after inoculation with all isolates used. Four cultivars and breeding lines (NAD 2298, Granal, Barke, BKH 4300) were composed of lines carrying different genes for resistance. Four different resistance alleles (Rph3, Rph7, Rph9 and Rph12) were detected alone or in combinations. Among tested cultivars and breeding lines, twenty had one gene for resistance and 8 had combination of different genes for resistance. The most common resistance allele was Rph12 (19 cultivars and breeding lines). Alleles Rph9 and Rph3 were postulated in 4 cultivars and breeding lines. Allele Rph7 was postulated to be present in only one cultivar Hanka. Different strategies for control of barley leaf rust using resistance genes were discussed.
