Races, disease symptoms and genetic variability in Pyrenophora tritici-repentis isolates from Oklahoma that cause tan spot of winter wheat

Abstract: In recent years, tan spot of wheat caused by the fungus Pyrenophora tritici-repentis has become more prevalent in Oklahoma. Experiments were conducted to investigate the race structure, disease symptoms and genetic variability in P. tritici-repentis isolates collected from winter wheat over three decades. Race determination was conducted for 16 isolates based on expression of necrosis and/or chlorosis produced on wheat differentials. Variability in disease symptoms expressed by 12 isolates was determined on 13… Show more

“…The genetic studies on isolates of P. tritici-repentis from different parts of the world have also been conducted using molecular markers. It was shown in several studies including one from Oklahoma in USA that race 1 was the predominant race in most regions ( Ali and Francl, 2003 ; Friesen et al., 2005 ; Kader et al, 2022 ).…”
