Races of Puccinia graminis f. sp. tritici with combined virulence to Sr13 and Sr9e in a field stem rust screening nursery in Ethiopia
(American Phytopathological Society (APS), 2012)
North American durum lines, selected for resistance to TTKSK (Ug99) and related races of Puccinia graminis f. sp. tritici in Kenya, became susceptible in Debre Zeit, Ethiopia, suggesting the presence of stem rust races ...
Article
Genetic gain from phenotypic and genomic selection for quantitative resistance to stem rust of wheat
(Crop Science Society of America, 2015)
Stem rust of wheat (Triticum aestivum L.) caused by Puccinia graminis f. sp. tritici Eriks. and E. Henn. is a globally important disease that can cause severe yield loss. Breeding for quantitative stem rust resistance ...
Article
Efficient use of historical data for genomic selection: a case study of stem rust resistance in wheat
(Crop Science Society of America, 2015)
Genomic selection (GS) is a methodology that can improve crop breeding efficiency. To implement GS, a training population (TP) with phenotypic and genotypic data is required to train a statistical model used to predict ...

Genetic analysis of adult plant resistance to yellow rust and leaf rust in common spring wheat Quaiu 3
(American Phytopathological Society (APS), 2013)
Identifying and utilizing rust resistance genes in wheat has been hampered by the continuous and rapid emergence of new pathogen races. A major focus of many wheat breeding programs is achieving durable adult plant resistance ...
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
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
Resistencia parcial y específica a roya del tallo en la línea avanzada de trigo harinero ‘Kijil’
(Sociedad Mexicana de Fitogenética, 2019)
El hongo Puccina graminis f. sp. tritici es el agente causal de la roya del tallo del trigo (Triticum aestivum), éste puede causar pérdidas del rendimiento hasta de 40 % en variedades susceptibles, además puede mutar y ...
Article
Phenotypic and genotypic characterization of Race TKTTF of Puccinia graminis f. sp. tritici that caused a Wheat Stem Rust Epidemic in Southern Ethiopia in 2013–14
(American Phytopathological Society (APS), 2015)
A severe stem rust epidemic occurred in southern Ethiopia during November 2013 to January 2014, with yield losses close to 100% on the most widely grown wheat cultivar, ‘Digalu’. Sixty-four stem rust samples collected from ...
Article
Identification and validation of single nucleotide polymorphic markers linked to Ug99 stem rust resistance in spring wheat
(Public Library of Science, 2017)
Wheat stem rust (Puccinia graminis f. sp. tritici Eriks. and E. Henn.) is one of the most destructive diseases world-wide. Races belonging to Ug99 (or TTKSK) continue to cause crop losses in East Africa and threaten global ...
Article
Progress towards genetics and breeding for minor genes based resistance to Ug99 and other rusts in CIMMYT high yielding spring wheat
(Elsevier, 2014)
Wheat rusts continue to cause significant losses worldwide despite major efforts given to their genetic control. This is due to frequent evolution and selection of virulence in pathogen overcoming the deployed race-specific ...
