Biology and Genetics of Crown Rust Disease in Ryegrasses

Crop Science, 2010
ABSTRACTThe most serious foliar disease of perennial ryegrass (Lolium perenne L.) is crown rust (caused by Puccinia coronata Corda f.sp. lolii Brown). Progress in resistance breeding using recurrent selection has been slow, due to lack of genetic knowledge. Puccinia coronata is a basidiomycete fungus with a complex life‐cycle involving both asexual and

Oat Crown Rust in Jordan: A Comprehensive Survey and Analysis

Jordan Journal of Biological Sciences
This research aimed to study the ecological context of Puccinia coronata f. sp. avenae (Pca), a pathogen affecting oats, in Jordan. The region is identified as a natural habitat for various wild oat species and the Rhamnaceae family, serving as an ...

Oat Maturity and Crown Rust Response¹

Crop Science, 1968
The crown rust (Puccinia coronata Cda. var. avenae Fraser & Led.) response of 114 F4 lines from each of two oat (Avena sativa L.) crosses was measured in terms of yield and kernel weight. Yield, kernel weight, and kernel density were used similarly for 130 pure line strains of oats.

Fungicide application improves seed yield of perennial ryegrass upon infection with stem and crown rust fungi

, 2020
Rust epidemics may have detrimental effects on seed yield in perennial ryegrass (Lolium perenne L.). Field trials comprising two cultivars of perennial ryegrass were established to evaluate the impact of stem rust (Puccinia graminis subsp.

Consistency of crown rust evaluation in ryegrass cultivars.

Communications in agricultural and applied biological sciences, 2011
Crown rust (Puccinia coronata) is the most important leaf disease in forage ryegrasses (Lolium spp.). In order to evaluate the stability in space and time of crown rust resistance a multisite rust evaluation trial was established by the European breeders association Eucarpia ( Fodder Crops Section).

Preserving Spring Oat Yields in New York Through Varietal Resistance to Crown Rust

, 2020
Crown rust is the principal disease of spring oat in New York. Management with resistance genes is effective but contingent on understanding varietal responses to local pathogen populations.

REACTION OF NON-CULTIVATED OATS FROM ISRAEL TO CANADIAN RACES OF CROWN RUST AND STEM RUST

Canadian Journal of Plant Science, 1963
Two hundred and two collections of non-cultivated oats from Israel, belonging to Avena sterilis L. and A. barbata Brot., were tested in the greenhouse at Winnipeg, Manitoba, for seedling and adult plant reaction to several important crown rust and stem rust races. Seeds of the collections found resistant in the greenhouse to one of the test races were

Assessment of virulence patterns in crown rust populations

Canadian Journal of Botany, 1968
Two methods of determining the virulence pattern of oat crown rust, Puccinia coronata f. sp. avenae, populations collected in 1965, 1966, and 1967, in Eastern and Western Canada were compared. The results with a single-pustule isolate from each of 50 field collections were as accurate as those obtained with two single-pustule isolates from 100 or more

Mexican Oat Germ Plasm as a Source of Resistance to Stem Rust and Crown Rust

Plant Disease, 1996
One hundred and three lines and cultivars of oat used as progenitors in the oat breeding programs in Chihuahua and Chapingo, Mexico, were tested for resistance to stem rust and crown rust. Each line or cultivar was evaluated in the seedling stage to races NA8, 16, 25, 26, 27, 28, and 55 of Puccinia graminis f. sp. avenae (stem rust), and isolates CR13,
