Abstract
Durable and efficient resistance of wheat to Puccinia triticina can be ensured only through good knowledge on the structure of the pathogen population. During 2005-2009 the structure and variability in the population of brown rust was investigated at Dobroudja Agricultural Institute – Bulgaria. Eight standard races were identified, which was an indication that the great race variability of the pathogen can not be encompassed by using the standard differential set. Therefore the race variability was determined with the help of isogenic lines applying the nomenclature suggested at COST 817. During the investigated period, 172 phenotypically different pathotypes were identified, pathotypes 63562 (41%), 63573 (20%) and 63572 (19.4%) being predominant. The genetic variability within the population was represented through 236 gene formulae of virulence, 106 of which were detected for the first time in the population. Highly efficient were genes Lr1, Lr9, Lr15, Lr28 and Lr42. During the period of investigation, pathotypes overcoming the resistance of gene Lr19 were identified thus decreasing significantly its efficiency
