Race non-specific resistance to rust diseases in CIMMYT spring wheats
Rust diseases continue to cause significant losses to wheat production worldwide. Although the life of effective race-specific resistance genes can be prolonged by using gene combinations, an alternative approach is to ...
Targeted mapping of ESTs linked to the adult plant resistance gene Lr46 in wheat using synteny with rice
The gene Lr46 has provided slow-rusting resistance to leaf rust caused by Puccinia triticina in wheat (Triticum aestivum), which has remained durable for almost 30 years. Using linked markers and wheat deletion stocks, we ...
Molecular genetic characterization of the Lr34/Yr18 slow rusting resistance gene region in wheat
Wheat expressed sequence tags (wESTs) were identiWed in a genomic interval predicted to span the Lr34/Yr18 slow rusting region on chromosome 7DS and that corresponded to genes located in the syntenic region of rice chromosome ...
Resistance of some Iraqi bread wheat cultivars to Puccinia triticina
Brown rust (leaf rust) caused by Puccinia triticina is one of the most serious diseases of wheat worldwide. In Iraq the occurrence and distribution of brown rust is more regular and uniform than that of other wheat rusts. ...
Progress towards genetics and breeding for minor genes based resistance to Ug99 and other rusts in CIMMYT high yielding spring wheat
Wheat rusts continue to cause significant losses worldwide despite major efforts given to their genetic control. This is due to frequent evolution and selection of virulence in pathogen overcoming the deployed race-specific ...
