Long‐Term Studies of Puccinia coronata f. sp. avenae in Australia Reveal High Pathogenic Diversity, Regional Virulence Differences, Evidence of Clonality and Rapid Emergence of Virulence Matching Deployed Host Resistance

open access: yesPlant Pathology, Volume 74, Issue 6, Page 1778-1795, August 2025.
Australia‐wide studies of the oat crown rust pathogen in 1998–2023 found emergence of virulence to resistance genes after their deployment and changes in populations from 2011 due to the emergence of pathotypes with virulence for Pc64. ABSTRACT Long‐term, detailed Australia‐wide studies of pathogenic variability in Puccinia coronata f. sp. avenae (Pca)

Phenotypic and genetic characterization of partial resistance to crown rust in Avena sativa L.

open access: yesCrop Breeding and Applied Biotechnology, 2012
Crown rust is a major oat disease. Partial resistance is a promising option for disease control for being potentially more durable than complete resistance.

Diversity of oat crown rust (Puccinia coronata f.sp. avenae) isolates detected by virulence and AFLP analyses

open access: yesPlant Protection Science, 2010
Forty Puccinia coronata f.sp. avenae isolates from several European countries and Israel were tested for virulence to 18 differential oat lines. Amplified Fragment Length Polymorphism (AFLP) analysis was used to evaluate diversity among the studied ...

Integrated disease management of leaf spots and crown rust of oat [PDF]

open access: yes, 2013
Non-Peer ReviewedCrown rust and leaf spots can reduce the yield and quality of oats. The objective of this research was to determine the effect of conventional fungicides, Actigard® and oat cultivars that vary in resistance to crown rust on leaf spot and

Multi-Environmental Trials Reveal Genetic Plasticity of Oat Agronomic Traits Associated With Climate Variable Changes

open access: yesFrontiers in Plant Science, 2018
Although oat cultivation around the Mediterranean basin is steadily increasing, its yield in these regions lags far behind those of Northern Europe.

Yield Losses Due to Crown Rust in Winter Oats in Alabama [PDF]

open access: yesPlant Health Progress, 2016
Crown rust is a common disease on winter oats in Alabama. While considered the most destructive disease of oats, little has been done in recent years, with current cultivars, to demonstrate yield losses due to crown rust. Field studies were conducted to determine the effect of fungicides and application timing on crown rust severity and yield.

Genetic Mapping of the Powdery Mildew Resistance Gene Pm13 on Oat (Avena sativa) Chromosome 1D

open access: yesPlant Breeding, Volume 144, Issue 3, Page 387-398, June 2025.
ABSTRACT Powdery mildew, caused by the biotrophic fungus Blumeria graminis DC. f. sp. avenae, is a widespread disease of oats, especially in the temperate regions of Western and Central Europe, and the use of resistant varieties is the most sustainable way to ensure stable yields.

Does partial resistance exert selection on oat crown rust populations?

open access: yes, 2004
Partial resistance to plant disease is often assumed to be durable, presumably because it exerts little or no selection pressure on the pathogen population. We tested this assumption in the field using partial resistance to crown rust of oat. Oat crown

A major quantitative trait locus conferring adult plant partial resistance to crown rust in oat

open access: yes, 2014
Background Crown rust, caused by Puccinia coronata f. sp. avenae, is the most important disease of oat worldwide. Adult plant resistance (APR), based upon partial resistance, has proven to be a durable rust management ...

URS Altiva – a new oat cultivar with high agronomic performance

open access: yesCrop Breeding and Applied Biotechnology, 2016
The oat cultivar URS Altiva, developed from the simple cross ‘UFRGS 995090-2 x URS 21’, and released by the Oat Breeding Program of the Federal University of Rio Grande do Sul (UFRGS) in 2015, presents high grain yield, high grain quality, desirable ...
