Virulence of Oat Crown Rust in Brazil and Uruguay [PDF]

open access: yesPlant Disease, 2005
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 ...

Genome-enabled analysis of population dynamics and virulence associated loci in the oat crown rust fungus Puccinia coronata f. sp. avenae

open access: yesbioRxiv, 2023
Puccinia coronata f. sp. avenae (Pca) is an important fungal pathogen causing crown rust that impacts oat production worldwide. Genetic resistance for crop protection against Pca is often overcome by the rapid virulence evolution of the pathogen.

Agronomic, leaf anatomy, morphology, endophyte presence and ploidy characterization of accessions of Festuca group rubra collected in northern Spain [PDF]

open access: yes, 2008
Fifteen accessions of Festuca group rubra collected in northern Spain were characterized and grouped into four Festuca taxa on the basis of leaf anatomy, morphology and ploidy; seven were identified as F. heteromalla; two as F.

Selection of AFLP markers linked with crown rust resistance in Lolium: efficiency of bulk segregant analysis in an Allogamous species

open access: yesPlant Protection Science, 2002
Ryegrasses are important forage species. An important foliar disease in Lolium is crown rust, caused by the fungus Pucciniacoronata. This cosmopolitan biotrophic fungus causes forage and seed losses, and decoloration of amenity grasslands.In breeding ...

Progress and bottlenecks in the early domestication of the perennial oilseed Silphium integrifolium, a sunflower substitute [PDF]

open access: yes, 2018
Silflower (Silphium integrifolium Michx.) is in the early stages of domestication as a perennial version of oilseed sunflower, its close relative. Grain crops with deep perennial root systems will provide farmers with new alternatives for managing soil ...

On Hirth Ring Couplings: Design Principles Including the Effect of Friction [PDF]

open access: yes, 2018
Rings with Hirth couplings are primarily used for the accurate positioning of axial-symmetric components in the machine tool industry and, generally, in mechanical components. It is also possible to use Hirth rings as connection tools.

CROWN RUST AND PASTURE PRODUCTION

open access: yesProceedings of the New Zealand Grassland Association, 1968
THERE is much information available on New Zealand's grasslands which indicates the vast difference between various theoretical plant (Mitchell, 1963) and animal (Hutton, 1963) production potentials and what is actually achieved in practice. Although these potentials are often regarded with scepticism, the fact remains that many research and ...

Assessing the potential of the rust fungus Puccinia spegazzinii as a classical biological control agent for the invasive weed Mikania micrantha in Papua New Guinea [PDF]

open access: yes, 2013
The rust fungus Puccinia spegazzinii was introduced into Papua New Guinea (PNG) in 2008 as a classical biological control agent of the invasive weed Mikania micrantha (Asteraceae), following its earlier release in India, mainland China and Taiwan.
