Previous studies of the causal agent of stem rust of oats (Puccinia graminis f. sp. avenae; P. g. avenae) in Australia have demonstrated a high level of pathogenic variability. In this work, the pathotypic structure of the Australian P. g. avenae population in 1999 was investigated, as well as the pathotypic and genetic diversity of a collection of 26 Australian isolates representing a 25-year period (1971-1996). In the 1999 sample, 16 races belonging to six international standard races were… CONTINUE READING
