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, ...
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 ...
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 ...
Wheat diseases and pests: a guide for field identification
This booklet is designed as a quick guide for identifying wheat and triticale diseases in the field. It is intended primarily for agricultural researchers, technicians, and farmers in developing nations, but will also be ...
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 ...
Rust diseases of wheat: concepts and methods of disease management
Roelfs, A.P., R.P. Singh, and E.E. Saari. 1992. Rust Diseases of Wheat: Concepts and methods of disease management. Mexico, D.F.: CIMMYT. 81 pages. The rust diseases of wheat are among the most studied of the plant diseases. ...
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 ...
Maladies et ravageurs du ble: guide d'identification au champ
Depourvus de chlorophylle, ce en quoi ils different des autres plantes, les champignons n'ont done pas de capacite de photosyntese. Au lieu d'elaborer leur propre nourriture, ils absorbent des elements nutritifs qu'ils ...
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% ...
