More than 2,000 isolates of Puccinia coronata f. sp. avenae collected in national virulence surveys were analyzed to determine regional patterns of virulence on 28 single-gene oat lines. From 1990 to 2000, frequencies of virulence to eight differenti

Frequent epidemics of leaf rust in Egypt have been attributed to the appearance of new races virulent on commonly grown wheat cultivars. In 1998, 1999, and 2000, 726 isolates of Puccinia triticina collected in Egypt were tested on a set of 20 single

Race-specific resistance to crown rust, the most important disease of oat (Avena sativa) in Bra-zil, often fails within a few years of use in Brazilian cultivars. Virulence of 144 isolates of Puccinia coronata from cultivated oat in Brazil in 1997 to

Race-specific resistance in oat does not provide adequate protection against crown rust because new virulent races of the pathogen often arise within a few years after cultivars with race-specific resistance are released. This study assessed levels o

Isolates of Puccinia triticina were obtained from wheat leaf collections made by cooperators throughout the United States and from surveys of wheat fields and nurseries in the Great Plains, Ohio Valley, and Gulf Coast states in 1996, 1997, and 1998.
