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
Leaf rust (Puccinia triticina) resistance in wheat (Triticum aestivum) cultivars grown in Northern Europe 1992-2002
(BioMed Central, 2006)
Diversity of resistance to leaf rust caused by Puccinia triticina can be enhanced in wheat (Triticum aestivum) cultivars through a better knowledge of resistance genes that are present in important cultivars and germplasm. ...

Genetics of leaf rust resistance in brambling wheat
(American Phytopathological Society (APS), 2008)
The CIMMYT-developed spring wheat ‘Brambling’ has a high level of adult-plant resistance (APR) to leaf rust caused by Puccinia triticina. Our objectives were to determine the genetic basis of resistance in ...
Article
Characterization of seedling infection types and adult plant infection responses of monogenic Sr gene lines to race TTKS of Puccinia graminis f. sp. tritici.
(American Phytopathological Society (APS), 2007)
Stem rust, caused by Puccinia graminis f. sp. tritici, historically was one of the most destructive diseases of wheat and barley. The disease has been under effective control worldwide through the widespread use of host ...
Article
Quantitative trait loci of stripe rust resistance in wheat
(Springer, 2013)
Over 140 QTLs for resistance to stripe rust in wheat have been published and through mapping flanking markers on consensus maps, 49 chromosomal regions are identified. Abstract: Over thirty publications during the last ...
Article
Genetic analysis of resistance to leaf rust and stripe rust in wheat cultivar Francolin#1
(American Phytopathological Society (APS), 2014)
Leaf rust and stripe rust are important diseases of wheat and can be controlled by growing resistant varieties. We investigated the genetic basis of resistance to both rusts in 198 F5recombinant inbred lines derived from ...
Article
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
Seedling and slow rusting resistance to stripe rust in Chinese common wheats
(American Phytopathological Society (APS), 2006)
Identification of seedling and slow stripe rust resistance genes is important for gene pyramiding, gene deployment, and developing slow-rusting wheat cultivars to control the disease. A total of 98 Chinese lines were ...
Article
The spread of stem rust caused by Puccinia graminis f. sp. tritici, with Virulence on Sr31 in wheat in Eastern Africa
(American Phytopathological Society (APS), 2006)
Stem rust resistance in wheat cultivars with Sr31 has been effective and durable worldwide for more than 30 years. Isolates of Puccinia graminis f. sp. tritici with virulence to Sr31 were detected in Uganda in 1999 (1). ...
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 ...
