Population structure and genotype-phenotype associations in a collection of oat landraces and historic cultivars

Frontiers in Plant Science, 2016
Population structure and genetic architecture of phenotypic traits in oat (Avena sativa L.) remain relatively under-researched compared to other small grain species.

Additional Sources of Broad-Spectrum Resistance to Puccinia coronata f. sp. avenae from Canadian Accessions of Avena barbata [PDF]

Plant Disease, 2010
Crown rust (Puccinia coronata f. sp. avenae) is considered the most damaging disease of oat and the use of race-specific seedling (Pc) genes for resistance has been the primary means of control. As these resistance genes from cultivated oat, Avena sativa, and the wild hexaploid animated oat, A.

Registration of CDL‐111 and CDL‐167 oat germplasm lines with pyramided adult plant crown rust resistance

Journal of Plant Registrations, Volume 18, Issue 2, Page 410-414, May 2024.
Abstract Oat (Avena sativa L.) production worldwide is constrained by crown rust (caused by Puccinia coronata f. sp. avenae), which can cause significant yield losses. The disease is often controlled by spraying fungicides or planting resistant cultivars.

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

Plant 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 ...

Broad-Spectrum Resistance to Crown Rust, Puccinia coronata f. sp. avenae, in Accessions of the Tetraploid Slender Oat, Avena barbata [PDF]

Plant Disease, 2009
The use of race-specific seedling genes for resistance has been the primary means of controlling crown rust of oat (Puccinia coronata). As resistance genes from hexaploid cultivated oat, Avena sativa and, later, the wild hexaploid animated oat, A. sterilis, were deployed in oat cultivars, corresponding virulence in the crown rust population increased ...

Genética da resistência à ferrugem-da-folha em aveia

Pesquisa Agropecuária Brasileira, 2001
A ferrugem-da-folha (Puccinia coronata f. sp. avenae) é a principal doença da cultura da aveia (Avena sativa L.), e o uso de cultivares resistentes é o método de controle mais importante.

Haplotype-Resolved Genomes of Diverse Oat Crown Rust Isolates Reveal Global Dispersion of Long-Lived Clonal Haplotypes with Limited Recombination

Molecular Plant-Microbe Interactions
Puccinia coronata f. sp. avenae (Pca), a fungal pathogen causing crown rust of oat, demonstrates rapid virulence evolution and adaptation to newly released cultivars.
