Barley Yellow Dwarf Luteovirus

One thousand and ninety-seven Aegilops accessions were evaluated for their reaction to a PAV serotype of barley yellow dwarf luteovirus (BYDV). The accessions tested belong to the species bicornis, biuncialis, caudata, crassa, columnaris, comosa, cylindrica, kotschyi, longissima, mutica, neglecta (= triaristata 4 ×), ovata, peregrina, searsii, sharonensis, speltoides, tauschii (= squarrosa), triuncialis, umbellulata, uniaristata, vavilovii and ventricosa. The first evaluation of virus levels in the different accessions was conducted at International Center for Agricultural Research in the Dry Areas (ICARDA), Aleppo, Syria, using double antibody sandwich ELISA (DAS-ELISA). Accession reaction ranged from highly resistant to highly susceptible. Thirty-eight Aegilops accessions resistant at ICARDA, were evaluated at Sainte-Foy, Quebec, Canada, by tissue-blot immunoassay. Diversity of response to BYDV infection was again observed in this elite group. Seven accessions belonging to the species biuncialis, caudata, neglecta and triuncialis were highly BYDV resistant at both locations; five of these originated from Bulgaria.

Barley Yellow Dwarf Luteovirus

Genotypes of perennial ryegrass cv. Ellett were classed as susceptible or resistant to infection with the PAV-related isolate of barley yellow dwarf luteovirus (BYDV) on the basis of dry weight yield and the presence or absence of detectable virus as measured with ELISA. In the inoculated treatments, there was a significant (P < 0.05) decrease in plant dry weight of susceptible compared to resistant genotypes, whereas in uninoculated treatments, there was no significant (P > 0.05) difference in yield between the two genotype classes. Superior plants from four cultivars of perennial ryegrass were selected from two field sites on the basis of superior winter growth and seasonal production. In glasshouse experiments, resistance to the virus was detected in these selections. The percentage of infected selections from individual cultivars varied between 18-46%, indicating that at least 50% were resistant to the virus.
