Morpho-physiological traits associated with cold stress tolerance in tropical maize (Zea mays L.)
(Consiglio per la Ricerca e la sperimentazione in Agricoltura, Unità di Ricerca per la Maiscoltura, 2010)
Winter season maize (Zea mays L.) has emerged a new crop in many parts of South and Southeast Asia, where the crop has to face low temperature regimes (<5°C) for few weeks during vegetative growth stage. The objective of ...

Genetic analysis of water-logging tolerance in tropical maize (Zea Mays L.)
(Consiglio per la Ricerca e la sperimentazione in Agricoltura, Unità di Ricerca per la Maiscoltura, 2010)
Approximately 80% of maize (Zea mays L.) in South and Southeast Asia is grown as a rain-fed crop, where temporary excessive soil moisture or water-logging during the summer-rainy season is one of the major production ...

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 ...

Genetic analysis of partial resistance to powdery mildew in bread wheat line Saar
(American Phytopathological Society (APS), 2006)
Powdery mildew, caused by Blumeria graminis (syn. Erysiphe graminis) f. sp. tritici, is an important disease of bread wheat (Triticum aestivum) in many countries. The CIMMYT bread wheat line Saar has exhibited a high level ...

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 ...
Article
Identification and molecular characterization of leaf rust resistance gene Lr14a in durum wheat
(American Phytopathological Society (APS), 2008)
Leaf rust, caused by Puccinia triticina, is an important disease of durum wheat (Triticum turgidum subsp. durum) and only a few designated resistance genes are known to occur in this crop. A dominant leaf rust resistance ...
Article
Detection of virulence to resistance gene Sr24 within race TTKS of Puccinia graminis f. sp. tritici
(American Phytopathological Society (APS), 2008)
The stem rust resistance gene Sr24 is effective against most races of Puccinia graminis f. sp. tritici, including race TTKS (syn. Ug99), and is used widely in commercial wheat cultivars worldwide. In 2006, susceptible ...
Article
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 ...

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 ...
