Genetic analysis of adult-plant resistance to leaf rust in five spring wheat genotypes
(American Phytopathological Society (APS), 2003)
Inheritance of adult-plant resistance to leaf rust, caused by Puccinia triticina, was studied in the progeny of a one-way diallel cross involving five CIMMYT-derived adult-plant resistant wheat (Triticum aestivum) genotypes ...
Article
Postulated genes for resistance to stripe rust in selected CIMMYT and related wheats
(American Phytopathological Society (APS), 1989)
Infection type data were used to postulate the presence of stripe rust seedling resistance genes in 20 CIMMYT and related bread wheats. Yr3, Yr6, Yr7, and Yr9 were hypothesized to be present in 12 lines, either alone or ...

Mapping of quantitative trait loci for adult plant resistance to stripe rust in German wheat cultivar Ibis
(Elsevier, 2012)
The German wheat cultivar Ibis has excellent adult plant resistance (APR) to stripe rust in Gansu, a hotspot for stripe rust in China. To elucidate the genetic basis of APR to stripe rust in Ibis, 237 F3 lines derived from ...

QTL mapping for adult-plant resistance to powdery mildew in bread wheat
(Institute of Crop Sciences, 2006)
Powdery mildew, caused by Blumeria graminis f. sp. tritici, is a major wheat disease in China. Use of adult-plant resistance is an effective method to develop wheat cultivars with durable resistance to powdery mildew. In ...

Bunt and smut diseases of wheat: concepts and methods of disease management
(CIMMYT, 1996)
Five bunt and smut diseases are regularly associated with wheat ( Triticum spp.). These are: common bunt (Tilletia spp.), dwarf bunt (T. controversa), Karnal bunt (T. indica), loose smut (Ustilago tritici), and flag smut ...
Book
Optimal search in ex situ collections of wheat genetic resources
(CIMMYT, 1998)
This paper develops a theoretical model for analyzing gene bank management decisions regarding the search for traits of economic value in ex situ collections of wheat. The model is applied to data on the probability of ...
Article
Estimating the economic impact of breeding nonspecific resistance to leaf rust in modern bread wheat
(American Phytopathological Society (APS), 1998)
Breeding for resistance to rust diseases in wheat is an example of productivity maintenance research. Productivity maintenance research is necessary to avoid contractions in the wheat supply curve that result from changes ...
Article
Genetics and breeding for durable resistance to leaf and stripe rusts in wheat
(The Scientific and Technology Research Council of Turkey, 2005)
Yellow (or stripe) and leaf (or brown) rusts, caused by Puccinia striiformis and P. triticina, respectively, are important diseases of wheat worldwide. Growing resistant cultivars is the most economical and environmentally ...
Book
The bacterial diseases of wheat: concepts and methods of disease management
(CIMMYT, 1997)
The most common bacterial pathogens that attack wheat are grouped under the names Xanthomonas translucens and Pseudomonas syringae. Pathovars (bacterial strains pathogenic to a specific host or hosts) included in X. ...
Article
Quantitative trait loci in bread wheat (Triticum aestivum L.) associated with resistance to stripe rust
(Taylor & Francis, 2008)
Stripe rust is an important wheat disease worldwide and resistance to stripe rust is often not controlled by race-specific resistance genes. To identify quantitative trait loci (QTL) affecting quantitative resistance to ...
