Evaluation of 226 barleys from Ethiopia for disease reaction to pathogens prevalent in Canada indicated that this region is a good source of resistance to Pyrenophora teres and Septoria passerinii but not to Cochliobolus sativus, Puccinia graminis tritici or barley stripe mosaic virus. Barleys with resistance to Ustilago nuda were confined to a relatively small area within the region.

Evaluation of 140 barleys from the Middle-East for disease reaction with Canadian pathogens indicates that this region could be a good source of resistance to Septoria passerinii, Pyrenophora teres and Rhynchosporium secalis but not to Puccinia graminis tritici, Ustilago nuda, Cochliobolus sativus or barley stripe mosaic virus.

Recent changes in the virulence patterns of Canadian barley pathogens have necessitated the search for new sources of genetic resistance in barley. Evaluation of 176 Turkish barley accessions for disease reaction to barley pathogens prevalent in Canada indicated that this germplasm is a good source of resistance to Septoria passerinii, Rhynchosporium secalis and the spot-form of Pyrenophora teres, but not to Cochliobolus sativus (spot blotch phase), Puccinia graminis tritici, Ustilago nuda or barley stripe mosaic virus. A small number of accessions with resistance to the net-form of P. teres were identified. Key words:Hordeum vulgare, barley, disease resistance, net blotch, scald, speckled leaf blotch

Poa semilatent virus (PSLV), which caused chlorosis and rapid death of inoculated wheat, infected a number of grasses susceptible to barley stripe mosaic virus (BSMV); but it also infected Agropyron trachycaulum and Poa palustris which were not susceptible to a barley strain or two oat-infecting strains of BSMV. Conversely BSMV caused local lesions on several species of Chenopodium that did not become infected with PSLV. BSMV protected wheat from infection by PSLV, but PSLV caused only partial protection from BSMV.The normal length and thickness of particles in leaf-dip preparations was 161 × 26 mμ for PSLV and 133 × 25 mμ for BSMV.Serological relationship was not indicated by the Ouchterlony agar double-diffusion test or leaf-dip serology. A distant relationship was shown with the microprecipitin test and the ring interface precipitin test. In cross absorption tests the titers of the antisera to the homologous viruses were not reduced by absorption with the heterologous viruses.PSLV and BSMV appear to be distantly related serotypes.
