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 ...
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 ...
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 ...
Interactions among genes Sr2/Yr30, Lr34/Yr18/Sr57 and Lr68 confer enhanced adult plant resistance to rust diseases in common wheat (Triticum aestivum L.) line 'Arula'
(Southern Cross Publishing Group, 2018)
Common wheat line Arula displays an acceptable level of adult plant resistance (APR) to stripe rust (YR), leaf rust (LR) and stem rust (SR) in Mexico, and to SR (Ug99 races) in Kenya. Present study was conducted to identify ...
Hybrid wheat prediction using genomic, pedigree, and environmental covariables interaction models
(Crop Science Society of America, 2019)
In this study, we used genotype × environment interactions (G×E) models for hybrid prediction, where similarity between lines was assessed by pedigree and molecular markers, and similarity between environments was accounted ...
Adult plant resistance to stem rust (Puccinia graminis f. sp. tritici) in Pakistani advanced lines and wheat varieties
(Southern Cross Publishing-Australia; Southern Cross Publishing Group, 2018)
After decades of effective wheat stem rust control, due mainly to use of the Sr31 resistance gene in wheat, as of the early 2000s new virulent strains of the stem rust fungus, especially the Ug99 or the TTKSK races, are ...
Resistance of some Iraqi bread wheat cultivars to Puccinia triticina
(Universitá Degli Studi Firenze, 2005)
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. ...
QTL Analysis and nested association mapping for adult plant resistance to Powdery Mildew in two bread wheat populations
CIMMYT wheat (Triticum aestivum L.) lines Francolin#1 and Quaiu#3 displayed effective and stable adult plant resistance (APR) to Chinese Blumeria graminis f. sp. tritici isolates in the field. To elucidate their genetic ...
Validation of candidate gene-based markers and identification of novel loci for thousand-grain weight in spring bread wheat
Increased thousand-grain weight (TGW) is an important breeding target for indirectly improving grain yield (GY). Fourteen reported candidate genes known to enhance TGW were evaluated in two independent and existing datasets ...
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 ...
