The economic impact in developing countries of leaf rust resistance breeding in CIMMYT-related spring bread wheat
This study was undertaken to estimate the economic impact of efforts since 1973 by the International Maize and Wheat Improvement Center (CIMMYT) to develop spring bread wheat varieties resistant to leaf rust caused by ...
Resistance in U.S. wheat to recent eastern African isolates of Puccinia graminis f. sp. tritici with virulence to resistance gene Sr31
(American Phytopathological Society (APS), 2006)
The stem rust resistance gene Sr31 derived from rye has been used as an important source of stem rust resistance in many wheat cultivars worldwide. Isolates of Puccinia graminis f. sp. tritici with virulence to Sr31 were ...
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. ...
Molecular mapping of a non-host resistance gene YrpstY1 in barley (Hordeum vulgare L.) for resistance to wheat stripe rust
(BioMed Central, 2010)
Cultivated barley ( Hordeum vulgare L.) is considered as a non-host or inappropriate host species for wheat stripe rust caused by Puccinia striiformis f. sp. tritici . Most barley cultivars show a broad-spectrum resistance ...
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 ...
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 ...
Sources of stem rust resistance in wheat-alien introgression lines
(American Phytopathological Society (APS), 2016)
Stem rust is one of the most devastating diseases of wheat. Widely virulent races of the pathogen in the Ug99 lineage (e.g., TTKSK) are threatening wheat production worldwide; therefore, there is an urgent need to enhance ...
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 ...
Resistance of some Iraqi bread wheat cultivars to Puccinia triticina
(Universitá Degli Studi Firenze, 2005)
Brown rust (leaf rust) caused by Puccinia triticina is one of the most serious diseases of wheat worldwide. In Iraq the occurrence and distribution of brown rust is more regular and uniform than that of other wheat rusts. ...
Seedling and slow rusting resistance to leaf rust in Chinese wheat cultivars
(American Phytopathological Society (APS), 2010)
Identification of resistance genes is important for developing leaf rust resistant wheat (Triticum aestivum) cultivars. A total of 102 Chinese winter wheat cultivars and advanced lines were inoculated with 24 pathotypes ...
