Stability in performance of quality protein maize under abiotic stress
(Consiglio per la Ricerca e la sperimentazione in Agricoltura, Unità di Ricerca per la Maiscoltura, 2008)
Quality protein maize (QPM) has emerged an affordable and viable option to alleviate protein malnutrition and reduce animal feed costs, given that its grain protein contains more than double the lysine and tryptophan ...
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 ...
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 ...
Practical guide to the identification of selected diseases of wheat and Barley
Selecting disease resistant germplasm is an essential component of breeding programs–in this case, wheat and barley programs. To achieve its objectives, the CIMMYT wheat program sistematically and consistently causes ...
Current status, likely migration and strategies to mitigate the threat to wheat production from race Ug99 (TTKS) of stem rust pathogen
(CABI Publishing, 2006)
Stem or black rust, caused by Puccinia graminis tritici, has historically caused severe losses to wheat (Triticum aestivum) production worldwide. Successful control of the disease for over three decades through the use of ...
Relationship between drought and excess moisture tolerance in maize (Zea mays L.)
(Southern Cross Publishing Group, 2008)
Maize crops grown during summer-rainy season in Asian tropics are prone to face both drought and excess moisture stress due uneven distribution patterns of monsoon rains in the region. We attempted to identify the relationship ...
Guía práctica para la identificación de algunas enfermedades de trigo y cebada
Un aspecto fundamental de los programas de fitomejoramiento –en este caso, de trigo y cebada– es la selección de germoplasma con resistencia a enfermedades. Para cumplir con sus objetivos, el programa de trigo del CIMMYT ...
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 ...
