Molecular marker mapping of Leaf Rust resistance gene Lr46 and its association with Strip Rust resistance gene Yr29 in wheat
(American Phytopathological Society (APS), 2003)
Leaf and stripe rusts, caused by Puccinia triticina and P. striiformis, respectively, are globally important fungal diseases of wheat that cause significant annual yield losses. A gene that confers slow rusting resistance ...
Grain yield, adaptation and progress in breeding for early-maturing and heat-tolerant wheat lines in South Asia
Maintaining wheat productivity under the increasing temperatures in South Asia is a challenge. We focused on developing early maturing wheat lines as an adaptive mechanism in regions suffering from terminal heat stress and ...
Genomic and pedigree-based prediction for leaf, stem, and stripe rust resistance in wheat
The unceasing plant-pathogen arms race and ephemeral nature of some rust resistance genes have been challenging for wheat (Triticum aestivum L.) breeding programs and farmers. Hence, it is important to devise strategies ...
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 ...
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 ...
Occurrence and impact of a new leaf rust race on durum wheat in Northwestern Mexico from 2001 to 2003
(American Phytopathological Society (APS), 2004)
Durum wheat (Triticum turgidum var. durum) is the main irrigated winter crop in northwestern Mexico. Historically, leaf rust, caused by Puccinia triticina, had not induced significant losses to durum production in the area ...
Molecular mapping and validation of SrND643: a new wheat gene for resistance to the stem rust pathogen Ug99 race group
(American Phytopathological Society (APS), 2015)
This study reports the identification of a new gene conferring resistance to the Ug99 lineage of races of Puccinia graminis f. sp. tritici in wheat (Triticum aestivum L.). Because the virulent races of stem rust pathogen ...
Effect of leaf rust on grain yield and yield traits of durum wheats with race-specific and slow-rusting resistance to leaf rust
(American Phytopathological Society (APS), 2006)
Leaf rust, caused by Puccinia triticina, is an important disease of durum wheat (Triticum turgidum) in many countries. We compared the effectiveness of different types of resistance in International Maize and Wheat Improvement ...
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% ...
