| dc.description | Tan spot, caused by <i>Pyrenophora tritici-repentis</i>, is a common disease in wheat-growing regions of Argentina. In this study 65 isolates of <i>P. tritici-repentis</i> obtained from different cultivars and wheat regions of Argentina were assessed for their virulence on six wheat cultivars/lines (Glenlea, Salomouni, Katepwa, M-3, 6B365 and 6B662) and for the presence/absence of the <i>Tox</i> genes based on a PCR approach. Thirty-six isolates were assigned to races, of which races 4 and 8 were dominant. Results for molecular analysis of <i>ToxA</i>, <i>ToxB</i>, <i>ToxB</i>-like and <i>toxb</i> genes showed that 57 isolates possessed the <i>ToxA</i> gene whereas only one isolate possessed <i>ToxA</i> and <i>ToxB</i> genes. There was no correlation between races and the toxin genotypes. It is suggested that <i>P. tritici-repentis</i> exhibits a complex race structure in Argentina. | |
