Components of rust resistance in lentil
Four components of resistance to Uromyces viciae-fabae, namely, latent period (LP), infection efficiency (IE), pustule size (PS) and spore production (SP) were evaluated on lentil (Lens ...

QTL map** of stripe, leaf and stem rust resistance genes in a Kariega × Avocet S doubled haploid wheat population
Adult plant resistance to stripe (yellow) rust in the wheat cultivar Kariega has previously been ascribed to a major quantitative trait locus (QTL) on each of chromosomes 2B and 7D, along with a number of mino...

Identification of adult plant resistance to stripe rust in the wheat cultivar Cappelle-Desprez
Following the appearance of stripe rust in South Africa in 1996, efforts have been made to identify new sources of durable resistance. The French cultivar Cappelle-Desprez has long been considered a source of ...

Seedling resistance to stem rust race Ug99 and marker analysis for Sr2, Sr24 and Sr31 in South African wheat cultivars and lines
The appearance and spread of races of Puccinia graminis f. sp. tritici with virulence for the Sr31 resistance gene has renewed interest in breeding for durable resistance to stem rust of wheat. Since the occurren...

High-resolution map** and new marker development for adult plant stripe rust resistance QTL in the wheat cultivar Kariega
Three major quantitative trait loci (QTL) contribute to the durable adult plant stripe rust resistance in the high-quality bread wheat cultivar Kariega; QYr.sgi-2B.1 and QYr.sgi-4A.1, and the pleiotropic resistan...

Application of remote sensing to identify adult plant resistance loci to stripe rust in two bread wheat map** populations
Phenoty** of wheat stripe rust in genetic studies has traditionally relied on quantifying disease by means of the modified Cobb Scale. This approach requires scoring of disease severity and response type, ei...

Phenotypic and genotypic description of Puccinia graminis f. sp. tritici race 2SA55 in South Africa
Race 2SA55 of the wheat stem rust pathogen, Puccinia graminis f. sp. tritici, was described for the first time during 2000 in South Africa. This race is of particular interest as it was the first local report of ...

Response of an International Triticale Collection to Puccinia triticina and Puccinia recondita sensu stricto and Assessment of Temperature Sensitivity in Leaf Rust Isolates
Triticale is derived from a cross between wheat and rye and the leaf rust pathogen of wheat, Puccinia triticina (Pt), and that of rye, P. recondita sensu stricto (Pr), can potentially cause disease in this crop. ...

The value of field ratings of differential lines for pathoty** Puccinia graminis f. sp. tritici
Traditional race phenoty** of cereal rusts is based on the pathogenicity of field isolates on seedlings using a set of differential host lines. These lines are regularly planted in the field, often as part o...

Comparing infection and colonisation of Puccinia graminis in barley and wheat
Barley, host to the wheat and rye attacking forms of the stem rust pathogen, Puccinia graminis (Pg), is considered inherently more resistant to Pg than wheat. To investigate whether this enhanced basal defence is...
