A North American System of Nomenclature for Puccinia coronata f. sp. avenae [PDF]

Plant Disease, 2000
A nomenclature system for designating virulence phenotypes of Puccinia coronata f. sp. avenae, the causal agent of oat crown rust, is proposed. Sixteen single gene oat (Avena sativa) lines, with seedling resistance genes Pc38, 39, 40, 45, 46, 48, 50, 51, 52, 54, 56, 58, 59, 62, 64, and 68, are the primary differentials.

Hidden Diversity of Crown Rust Resistance within Genebank Resources of Avena sterilis L.

Agronomy, 2021
The most widespread and damaging fungal disease of the oat plant is crown rust. Resistance to the crown rust pathogen, Puccinia coronata Cda. f. sp. avenae (Pca), at the seedling stage of Avena sterilis accessions from the Polish national genebank was ...

Mega‐environment analysis and breeding for specific adaptation

Crop Science, Volume 63, Issue 2, Page 480-494, March/April 2023., 2023
Abstract Mega‐environment (ME) analysis is analysis of multi‐year, multi‐location crop variety trial data conducted in a target region of a crop to understand the magnitude and nature of genotype‐by‐environment interaction (GE) of the crop in the region. If repeatable GE patterns are identified, then the target region must be divided into subregions or

Pathogenic Variability of Puccinia coronata f. sp. avenae and P. graminis f. sp. avenae on Oat in South Africa [PDF]

Plant Disease, 2001
Although crown rust (caused by Puccinia coronata f. sp. avenae) and stem rust (caused by Puccinia graminis f. sp. avenae) are generally considered to be the most widespread and damaging diseases of oat (Avena spp.) in South Africa, pathogenic variability has never been studied.

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 ...

Detection of Maternal and Cytoplasmic Effects on Resistance to Zymoseptoria tritici in Durum Wheat

BioMed Research International, Volume 2022, Issue 1, 2022., 2022
Septoria tritici blotch (STB) is a major disease problem of wheat worldwide. To optimize the introgression of resistance genes in elite genotypes throughout traditional or molecular breeding programs, a full understanding of the quantitative inheritance of resistance to Zymoseptoria tritici, plant height (PH), and thousand kernel weight (TKW) is needed.

Oat mega‐environments in Canada

Crop Science, Volume 61, Issue 2, Page 1141-1153, March/April 2021., 2021
Abstract Genotype × environment interaction (GE) is a perennial problem in plant breeding and must be dealt with. Dealing with GE starts with differentiation of repeatable GE from unrepeatable GE in a target region. Repeatable GE can be used by dividing the target region into mega‐environments (MEs) and breeding ME‐specific cultivars, and unrepeatable ...

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 ...

Searching for Novel Oat Crown Rust Resistance in Diploid Oat Avena strigosa Schreb. Reveals the Complexity and Heterogeneity of the Analyzed Genebank Accessions

Agriculture, 2023
Crown rust, one of the most destructive diseases of oat, regularly occurs worldwide and leads to significant yield losses. The constant evolution of the Puccinia coronata f. sp.

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.
