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

Discovery and Chromosomal Location a Highly Effective Oat Crown Rust Resistance Gene Pc50-5. [PDF]
Crown rust, caused by Puccinia coronata f. sp. avenae, is one of the most destructive fungal diseases of oat worldwide. Growing disease-resistant oat cultivars is the preferred method of preventing the spread of rust and potential epidemics.

Identification of Resistant Sources to Crown Rust (Puccinia Coronata) in Oat [PDF]
This study was conducted to search for new resistant sources to oat leaf rust as well as to characterize the macroscopic components of resistance to crown rust under controlled conditions. One hundred twenty different accessions of oats obtained from the

Identification of QTLs for horizontal resistance to crown rust in oat
In order to identify molecular markers associated with genes for horizontal resistance to crown rust in oat, a population consisting of 158 F8 recombinant inbred lines from a cross of ‘MN841801-1 × Noble-2’ was mapped with 112 RFLP loci.

Search of incomplete resistance of oat to crown rust
Basic goal in oat breeding for resistance to crown rust is to provide a long-term protection. Several investigations have shown that oat cultivars which possess incomplete resistance factors retain their resistance for a long time. Incomplete resistance appeared useful, particularly when cultivars are grown on large areas.

A study of the rust reactions of wheat varieties to 20 physiologic races of stem rust has shown that several varieties of the vulgare type, namely, McMurachy, Eureka, and several strains from Kenya, East Africa, are immune in the seedling stage at ordinary greenhouse temperatures (55° F. to 80° F. daily).

Virulence of Oat Crown Rust in Mexico [PDF]
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.

Virulence Associations in Oat Crown Rust [PDF]
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 Brazil and Uruguay [PDF]
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 ...
