Natural population of oat crown rust in Tunisia

Phytopathologia Mediterranea, 2010
Oat crown rust, caused by Puccinia coronata f. sp. avenae, is considered the most widespread and damaging disease of oat (Avena sativa) in Tunisia. The virulence structure of the natural oat rust population in Tunisia was studied in four areas from 2002 ...

Hidden Diversity of Crown Rust Resistance within Genebank Resources of Avena sterilis L.

Agronomy, 2021
The most widespread and damaging fungal disease of the oat plant is crown rust. Resistance to the crown rust pathogen, Puccinia coronata Cda. f. sp. avenae (Pca), at the seedling stage of Avena sterilis accessions from the Polish national genebank was ...
