Preliminary screening of Avena sterilis L. for resistance to crown rust
Agronomy Science, 2020 The best source of crown rust resistance genes (Pc) in genus Avena is a wild hexaploid A. sterilis L. In this study, accessions of A. sterilis gathered from European and North American gene banks, originated from 21 countries were evaluated at the ...

Resistance to Puccinia coronata f. sp. avenae in Avena magna, A. murphyi, and A. insularis [PDF]
Plant Disease, 2016 Wild oat tetraploids of the section Pachycarpa have already been proven to be a rich source of useful genes but have largely been unexploited for Puccinia coronata resistance. In this study, accessions of Avena magna, A. murphyi, and A. insularis gathered from European and North American gene banks were evaluated at the seedling stage for crown rust ...

Detection of race-specific resistance against Puccinia coronata f. sp. avenae in Brachypodium species [PDF]
Phytopathology®, 2018 AbstractOat crown rust caused by Puccinia coronata f. sp. avenae is the most destructive foliar disease of cultivated oat. Characterization of genetic factors controlling resistance responses to Puccinia coronata f. sp. avenae in non-host species could provide new resources for developing disease protection strategies in oat.

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 ...

Axenic culture of two rust fungi, Puccinia coronata f. sp. avenae and P. recondita f. sp. tritici.
Japanese Journal of Phytopathology, 1978 Urediniospores of Puccinia coronata f. sp. avenae race 367 and P. recondite f. sp. tritici race 45 were respectively cultured on an artificial medium. Urediniospores free of contaminating microorganisms were obtained by aseptic leaf culture. After the urediniospores were separately seeded on the medium, both rust fungi grew well and then formed white ...
