Sources and Genetics of Crown Rust Resistance in Barley [PDF]

open access: yesPhytopathology®, 2002
Crown rust, caused by Puccinia coronata var. hordei, is a new disease threat to barley in the Great Plains region of the United States. Deployment of resistant cultivars is the only economically viable option for the control of this disease. Thus, the objective of this study was to investigate the sources and genetics of crown rust resistance in ...

Virulence of Oat Crown Rust in Brazil and Uruguay [PDF]

open access: yesPlant Disease, 2005
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 1999 and 36 isolates from Uruguay in 1994-95 and 1998 was tested on a set of 27 oat crown rust ...

Genome-enabled analysis of population dynamics and virulence associated loci in the oat crown rust fungus Puccinia coronata f. sp. avenae

open access: yesbioRxiv, 2023
Puccinia coronata f. sp. avenae (Pca) is an important fungal pathogen causing crown rust that impacts oat production worldwide. Genetic resistance for crop protection against Pca is often overcome by the rapid virulence evolution of the pathogen.

Selection of AFLP markers linked with crown rust resistance in Lolium: efficiency of bulk segregant analysis in an Allogamous species

open access: yesPlant Protection Science, 2002
Ryegrasses are important forage species. An important foliar disease in Lolium is crown rust, caused by the fungus Pucciniacoronata. This cosmopolitan biotrophic fungus causes forage and seed losses, and decoloration of amenity grasslands.In breeding ...

CROWN RUST AND PASTURE PRODUCTION

open access: yesProceedings of the New Zealand Grassland Association, 1968
THERE is much information available on New Zealand's grasslands which indicates the vast difference between various theoretical plant (Mitchell, 1963) and animal (Hutton, 1963) production potentials and what is actually achieved in practice. Although these potentials are often regarded with scepticism, the fact remains that many research and ...

Genotypic and resistance profile analysis of two oat crown rust differential sets urge coordination and standardisation

open access: yesbioRxiv, 2023
Puccinia coronata f. sp. avenae (Pca) is the causal agent of the disease known as crown rust which represents a bottleneck in oat production worldwide.

Mapping of crown rust (Puccinia coronata f. sp. avenae) resistance gene Pc54 and a novel quantitative trait locus effective against powdery mildew (Blumeria graminis f. sp. avenae) in the oat (Avena sativa) line Pc54.

open access: yesPhytopathology, 2022
The Pc54 oat line carries the crown rust resistance gene 'Pc54' and an unknown gene effective against powdery mildew. In this study two recombinant inbred line populations were developed to identify the genomic locations of the two genes and producing ...

URS Brava – a new oat cultivar with partial resistance to crown rust [PDF]

open access: yesCrop Breeding and Applied Biotechnology, 2015
The cultivar URS Brava, obtained from a simple cross between the line ‘UFRGS 995078-2’ and the cultivar ‘URS 21’, shows high grain yield and stability, high grain quality, desirable agronomical traits and partial resistance to crown rust, caused by the
