Population structure of leaf pathogens of common spring wheat in the West Asian regions of Russia and North Kazakhstan in 2017
(Institute of Cytology and Genetics of Siberian Branch of the Russian Academy of Sciences, 2018)
Wheat diseases affecting leaves like leaf rust (Puccinia triticina), tan spot (Pyrenophora tritici-repentis) and spot blotch (Cochliobolus sativus = Bipolaris sorokiniana) are widely spread and potentially dangerous in the ...
Article
Field resistance of wheat (Triticum aestivum L.) genotypes from different countries to leaf rust (Puccinia triticina)
(The Scientific and Technology Research Council of Turkey, 2008)
Puccinia triticina causes leaf rust in wheat and results in severe yield losses in mild wheat growing areas of Turkey: Thrace, Marmara, Mediterranean, and Çukurova. A feasible way to avoid any damage is to grow slow rusting ...
Article
Identification and mapping of leaf, stem and stripe rust resistance quantitative trait loci and their interactions in durum wheat
(Springer Verlag, 2012)
Leaf rust (Puccinia triticina Eriks.), stripe rust (Puccinia striiformis f. tritici Eriks.) and stem rust (Puccinia graminis f. sp. tritici) cause major production losses in durum wheat (Triticum turgidum L. var. durum). ...
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 ...
Article
Association mapping of North American spring wheat breeding germplasm reveals loci conferring resistance to Ug99 and other African stem rust races
(BioMed Central, 2015)
Background: The recently identified Puccinia graminis f. sp. tritici (Pgt) race TTKSK (Ug99) poses a severe threat to global wheat production because of its broad virulence on several widely deployed resistance genes. ...
Article
Rust and smut diseases of wheat in India
(Division of Mycology and Plant Pathology, Indian Agricultural Research Institute, 1970)
Wheat diseases in India were last summarized in 1961. During the last 2 years extensive nationwide disease surveys were made. This paper describes the current situation for rust and smuts only. The three rusts, brown, ...
Article
Emergence and spread of new races of wheat stem rust fungus: continued threat to food security and prospects of genetic control
(American Phytopathological Society (APS), 2015)
Race Ug99 (TTKSK) of Puccinia graminis f. sp. tritici, detected in Uganda in 1998, has been recognized as a serious threat to food security because it possesses combined virulence to a large number of resistance genes found ...
Article
Enhanced resistance in wheat against stem rust achieved by marker assisted backcrossing involving three independent Sr genes
(Elsevier, 2015)
Marker assisted backcrossing (MABC) was used to transfer the three stem rust (Puccinia graminis tritici)resistant genes Sr25, SrWeb and Sr50 into the popular Indian wheat cv. HUW234. The donor was theCIMMYT breeding line ...
Article
A high density GBS map of bread wheat and its application for dissecting complex disease resistance traits
(BioMed Central, 2015)
Genotyping-by-sequencing (GBS) is a high-throughput genotyping approach that is starting to be used in several crop species, including bread wheat. Anchoring GBS tags on chromosomes is an important step towards utilizing ...
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 ...
