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 ...
Identification of genomic associations for adult plant resistance in the background of popular South Asian wheat cultivar, PBW343
Rusts, a fungal disease as old as its host plant wheat, has caused havoc for over 8000 years. As the rust pathogens can evolve into new virulent races which quickly defeat the resistance that primarily rely on race ...
Strategies for selecting crosses using genomic prediction in two wheat breeding programs
(Crop Science Society of America, 2017)
The single most important decision in plant breeding programs is the selection of appropriate crosses. The ideal cross would provide superior predicted progeny performance and enough diversity to maintain genetic gain. The ...
Genetic impact of Rht dwarfing genes on grain micronutrients concentration in wheat
Wheat is a major staple food crop providing about 20% of dietary energy and proteins, and food products made of whole grain wheat are a major source of micronutrients like Zinc (Zn), Iron (Fe), Manganese (Mn), Magnesium ...
Harnessing diversity in wheat to enhance grain yield, climate resilience, disease and insect pest resistance and nutrition through conventional and modern breeding approaches
Current trends in population growth and consumption patterns continue to increase the demand for wheat, a key cereal for global food security. Further, multiple abiotic challenges due to climate change and evolving pathogen ...
Phenotypic and genotypic characterization of Race TKTTF of Puccinia graminis f. sp. tritici that caused a Wheat Stem Rust Epidemic in Southern Ethiopia in 2013–14
(American Phytopathological Society (APS), 2015)
A severe stem rust epidemic occurred in southern Ethiopia during November 2013 to January 2014, with yield losses close to 100% on the most widely grown wheat cultivar, ‘Digalu’. Sixty-four stem rust samples collected from ...
Analisis de virulencia de la roya amarilla (Puccinia striiformis f. sp. tritici) del trigo (Triticum aestivum L.) En los valles altos de Mexico
(Colegio de Postgraduados, 2010)
La roya amarilla (Puccinia striiformis f. sp. tritici) del trigo (Triticum aestivum L.) causa pérdidas importantes en rendi¬miento en los Valles Altos de México, debido a que el hongo puede evolucionar y vencer la resistencia ...
Characterization and mapping of Leaf Rust and Stripe Rust resistance loci in hexaploid wheat lines UC1110 and PI610750 under Mexican environments
Growing resistant wheat varieties is a key method of minimizing the extent of yield losses caused by the globally important wheat leaf rust (LR) and stripe rust (YR) diseases. In this study, a population of 186 F8 recombinant ...
Genetic analysis of adult-plant resistance to leaf rust in five spring wheat genotypes
(American Phytopathological Society (APS), 2003)
Inheritance of adult-plant resistance to leaf rust, caused by Puccinia triticina, was studied in the progeny of a one-way diallel cross involving five CIMMYT-derived adult-plant resistant wheat (Triticum aestivum) genotypes ...
Pathogenicity variations of Puccinia recondita f. sp. tritici and P. graminis f. sp. tritici in wheat growing areas of Mexico during 1988 and 1989
(American Phytopathological Society (APS), 1991)
A survey of Puccinia recondita f. sp. tritici in Mexico during 1988 and 1989 indicated the presence of 23 pathotypes. In the Pacific region and Highland Plateau, pathotype TCB/TD predominated both years, followed by TBD/TM. ...
