Breeding <strong>of</strong> cereal cultivars resistant to Fusarium fungi causing fusarium head<br />
blight, root rot and snow mold is the important problem all over the world,<br />
including Russia. Genetic diversity <strong>of</strong> world gene accessions was studied for<br />
selection <strong>of</strong> breeding sources resistant to Fusarium fungi. Ecological and genetic<br />
differentiation <strong>of</strong> species <strong>of</strong> host plant was taken into account. Total <strong>of</strong> 5000<br />
wheat cultivars from different genetic groups was screened with identification <strong>of</strong><br />
different types and rates <strong>of</strong> disease severity <strong>of</strong> root rot and snow mold. There was<br />
6,7% resistant lines from winter accession <strong>of</strong> bread wheat (T. aestivum), 8,8% -<br />
from spring accessions <strong>of</strong> bread wheat, 1,4% - from spring accessions <strong>of</strong> durum<br />
wheat (T. durum) selected by screening to resistance. The high resistance was<br />
shown for Triticale lines. The samples from Aegilops aucheri, Ae.ovata,<br />
Ae.columnaris, Ae.triuncialis, Ae.koteshyi species were resistant to fusarium<br />
diseases. Distribution <strong>of</strong> resistant wheat lines dependent on their geographical<br />
origin. Winter wheat cultivars with moderate resistance to fusarium root rot were<br />
dominated in Western Europe (Icsu – France, Horpacsi – Hungry, Yasen –<br />
Bulgaria etc.) and in North America (Chiefkan, Archamp, Benni, Coker 9227 –<br />
USA etc.). Resistant spring bred wheat cultivars were revealed within 8<br />
ecological-geographical groups presented majority <strong>of</strong> countries. The focus <strong>of</strong><br />
interest was on accessions introduced from North and South America, India, as<br />
well as international and regional nurseries (Laura - Canada, Achut - Nepal,<br />
Vectis - USA, BVF-2 - Mexico etc.). Durum wheat cultivars with moderate<br />
resistance were dominated in the Mediterranean regions and in the southwesten<br />
Asia (Aya de Carvo - Portugal, 80/57 – Italy, Ak-bugda - Dagestan, k.6397 -<br />
Georgia, k.6397, k. 36269 - Armenia). The origin <strong>of</strong> wheat cultivars with high<br />
resistance to snow mold was West Europe (Glockner, Agent, Aron - Germany,<br />
Szemes - Hungary, Turda 81 - Rumania, Sol IV - Sweden).<br />
