AN ASSOCIATION OF STEM RUST AND CROWN RUST RESISTANCE IN JOSTRAIN OATS
Canadian Journal of Genetics and Cytology, 1968Rodney backcross lines carrying single genes for stem rust resistance were tested with 10 cultures of crown rust. Lines possessing genes Pg-1, Pg-2, Pg-4 and pg-8 were susceptible to all cultures of crown rust used, whereas the line carrying Pg-3 was highly resistant to several of these cultures. Studies of 51 Victory2 x Jostrain F2 backcross families

Breeding perennial ryegrass with better crown rust resistance
Plant Breeding, 1996AbstractImproving rust resistance is one of the main goals in our breeding programme with perennial ryegrasses. We have studied the behaviour of our breeding material over several years in several locations under natural and artificial infection conditions.

Plant Disease
Oat production in the Mediterranean region face important yield and quality challenges, with crown rust (caused by Puccinia coronata f. sp. avenae) being one of the most important critical biotic constraints.

Induction to Resistance to Crown Rust in Oat
Journal of Phytopathology, 1996AbstractInduction of resistance to crown rust, caused by Puccinia coronata Cda. var, avenae Frazer et Led., occurred in seedlings of three genetic lines of oats (Avena sativa L.) inoculated sequentially with one of three inducer‐challenger combinations of the pathogen.

Canadian Journal of Research, 1940
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).

Biology and Genetics of Crown Rust Disease in Ryegrasses
Crop Science, 2010ABSTRACTThe 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 SciencesThis 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, 1968The 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.

Preserving Spring Oat Yields in New York Through Varietal Resistance to Crown Rust
, 2020Crown 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.

Consistency of crown rust evaluation in ryegrass cultivars.
Communications in agricultural and applied biological sciences, 2011Crown 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).
