Pathogenic divergence of Central European and Australian populations of Blumeria graminis f. sp. hordei
Original language description
Hosts and pathogens have adapted their response to each other through genetic changes that have arisen during the course of their co-evolution. In developed countries the longevity of varieties is often short; new varieties frequently possess novel geneswith specific resistance to pathogens. The latter must adapt to the resistance genes to maintain pathogenicity. To study this adaptation, 50 Central European and 50 Australian isolates of Blumeria graminis f. sp. hordei (Bgh) were tested on 50 barley differential varieties with different specific resistance genes. All the Central European isolates differed from each other in their virulence combinations and belonged to 50 various pathotypes, whereas Australian isolates comprised 37 pathotypes. None ofthe pathotypes detected in Central Europe was identical or similar to any of those in Australia. This can be attributed to the much higher number of virulences in Central European isolates that developed over a long period of contact with
