Natural population of oat crown rust in Tunisia
Phytopathologia Mediterranea, 2010 Oat crown rust, caused by Puccinia coronata f. sp. avenae, is considered the most widespread and damaging disease of oat (Avena sativa) in Tunisia. The virulence structure of the natural oat rust population in Tunisia was studied in four areas from 2002 ...

Genome-Wide Association Mapping of Crown Rust Resistance in Oat Elite Germplasm
The Plant Genome, 2017 Oat crown rust, caused by f. sp. , is a major constraint to oat ( L.) production in many parts of the world. In this first comprehensive multienvironment genome-wide association map of oat crown rust, we used 2972 single-nucleotide polymorphisms (SNPs ...

Crown rust on oat genotypes with different levels of resistance: damages and losses [PDF]
Ciência Rural, 2021 : The evolution in virulence of Puccinia coronata f. sp. avenae has challenged the genetic resistance to crown rust in oat genotypes. New resistance sources are constantly required for yield stabilization and costs reduction.

Selection for partial resistance to crown rust in oat
, 2020 Crown rust, caused by the fungal pathogen, Puccinia coronata, severely reduces kernel quality and grain yield in oat. Partial resistance is considered to be a durable form of rust resistance. The objectives of this study were to evaluate the effectiveness of index selection as a method for improving partial resistance to crown rust, grain yield and ...

A high-resolution haplotype collection uncovers somatic hybridization, recombination and intercontinental movement in oat crown rust. [PDF]
PLoS GeneticsThe population structure and evolution of basidiomycetes like rust fungi are influenced by complex reproductive cycles and dikaryotic life stages where two independent nuclear haplotypes are present in the cell.

Genome-wide association studies reveal genetic control of nutritional quality, milling traits, and agronomic characteristics in oat (Avena sativa L.). [PDF]
Plant GenomeAbstract Marker‐trait associations (MTAs) are invaluable to the understanding of biological processes and implementation of marker‐assisted selection (MAS) to increase genetic gain in modern breeding programs. In this study, a genome‐wide association study (GWAS) was performed to identify MTAs that influence oat nutritional quality, as well as ...

Responses to Selection for Partial Resistance to Crown Rust in Oat
Crop Science, 2006 ABSTRACTCrown rust, caused by the fungal pathogen, Puccinia coronata Corda var. avenae W.P. Fraser Ledingham, reduces kernel quality and grain yield in oat (Avena sativa L.). Partial resistance is considered to be a durable form of rust resistance. This study sought to evaluate the feasibility of simultaneously improving partial resistance to crown ...
