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 ...
Evaluation of CIMMYT germplasm for resistance to leaf spotting diseases of wheat
(Czech Academy of Agricultural Sciences, 2011)
The leaf spotting disease complex is a major biotic constrain in enhancing grain production in the major wheat growing regions. Two leaf spotting diseases, tan spot, caused by an ascomycete fungus Pyrenophora tritici-repentis, ...
Transferencia del gen Lr14a de trigos harineros a trigos cristalinos y expresion de la resistencia a roya de la hoja
(Sociedad Mexicana de Fitogenética, 2010)
El origen del gen de resistencia Lr14a a roya de la hoja causada por Puccinia triticina E. es el trigo tetraploide 'Yaroslav emmer' (Triticum dicoccum L.). En México, todas las razas de trigo harinero (T. aestivum) importantes ...
Genetica de la resistencia a roya amarilla en plantas adultas de trigo harinero
(Sociedad Mexicana de Fitogenética, 2009)
La roya lineal amarilla del trigo (Triticum aestivum L.) causada por Puccinia striiformis f. sp. tritici es una enfermedad de creciente importancia en los Valles Altos de México, pues llega a causar perdidas en el rendimiento ...
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 ...
New genes for leaf rust resistance in CIMMYT durum wheats
(American Phytopathological Society (APS), 2005)
Leaf rust, caused by Puccinia triticina, has become an important disease of durum wheat (Triticum turgidum) in Mexico since the detection in 2001 of BBG/BN, a new race virulent on all common cultivars and on more than 80% ...
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 ...
Genomic prediction of genetic values for resistance to wheat rusts
(Crop Science Society of America, 2012)
Durable resistance to the rust diseases of wheat (Triticum aestivum L.) can be achieved by developing lines that have race-nonspecific adult plant resistance conferred by multiple minor slow-rusting genes. Genomic selection ...
