QTL mapping of oat crown rust resistance in Australian fields and identification of a seedling resistance locus in oat line GS7. [PDF]

Theor Appl Genet
The development of oat cultivars with resistance to crown rust caused by Puccinia coronata f. sp. Avenae (Pca) is key for sustainable disease control. This study examined two recombinant inbred line populations, Provena x GS7 and Boyer x GS7, to identify

Development and accuracy assessment of molecular markers associated with crown rust resistance genes in oat. [PDF]

PLoS One
Crown rust caused by Puccinia coronata Cda. f. sp. avenae P. Syd. (Pca) is considered the most destructive disease of oat, causing yield and grain quality losses.

Identification of molecular markers for the Pc39 gene conferring resistance to crown rust in oat. [PDF]

Theor Appl Genet, 2020
Six new PCR-based markers for the Pc39 crown rust resistance gene in Avena sativa L. were developed. Pc39 was mapped to Mrg11 of the oat consensus map using BLASTn analysis.

Genome-wide markers for seed yield and disease resistance in perennial ryegrass

Crop Journal, 2022
The market success of perennial ryegrass (Lolium perenne L.) cultivars depends on sufficient seed production, as they are propagated by seed. However, breeding for high quality forage production reduces seed yield, and breaking the negative correlation ...

Virulence Associations in Oat Crown Rust [PDF]

Phytopathology®, 2005
Isolates of Puccinia coronata obtained from natural populations of Avena sterilis in Israel, winter oat (A. sativa) cultivars in Texas, and spring oat cultivars in the Northern Plains states of Minnesota, North Dakota, and South Dakota were analyzed for significance of pairwise virulence associations.

Virulence of Oat Crown Rust in Mexico [PDF]

Plant Disease, 2005
Virulence of isolates of Puccinia coronata collected during 1992 to 1998 from Sonora, Chihua-hua, Nuevo Leon, and five states in Central Mexico were compared on a set of 27 differential oat (Avena sativa) lines with different genes for race-specific resistance.

Genomic Prediction and Genotype-by-Environment Interaction Analysis of Crown and Stem Rust in Ryegrasses in European Multi-Site Trials

Agronomy, 2021
Climate change calls for novel approaches to include environmental effects in future breeding programs for forage crops. A set of ryegrasses (Lolium) varieties was evaluated in multiple European environments for crown rust (Puccinia coronata f. sp. lolii)

A high-resolution haplotype pangenome uncovers somatic hybridization, recombination and intercontinental migration in oat crown rust

bioRxiv
Basidiomycetes like rust fungi have complex reproductive cycles and dikaryotic life stages which influence their population structure and evolution. Puccinia coronata f. sp.

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

Phytopathology®, 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 ...
