Molecular mapping and validation of SrND643: a new wheat gene for resistance to the stem rust pathogen Ug99 race group
(American Phytopathological Society (APS), 2015)
This study reports the identification of a new gene conferring resistance to the Ug99 lineage of races of Puccinia graminis f. sp. tritici in wheat (Triticum aestivum L.). Because the virulent races of stem rust pathogen ...
Article
Genetic analysis of morpho-physiological traits and yield components in F2 partial diallel crosses of bread wheat (Triticum aestivum L.)
(Universidad Nacional de Colombia (Sede Medellín), 2017)
Wheat breeding in the semi-arid region of Algeria aims to develop new cultivars combining high productivity and good abiotic stress tolerance. Therefore, it is essential to understand the mode of gene effects implicated ...
Article
How can we improve crop genotypes to increase stress resilience and productivity in a future climate? A new crop screening method based on productivity and resistance to abiotic stress
(Oxford University Press; Society for Experimental Biology, 2016)
The need to accelerate the selection of crop genotypes that are both resistant to and productive under abiotic stress is enhanced by global warming and the increase in demand for food by a growing world population. In this ...
Article
Genetic gain from phenotypic and genomic selection for quantitative resistance to stem rust of wheat
(Crop Science Society of America, 2015)
Stem rust of wheat (Triticum aestivum L.) caused by Puccinia graminis f. sp. tritici Eriks. and E. Henn. is a globally important disease that can cause severe yield loss. Breeding for quantitative stem rust resistance ...

International testing program in wheat, triticale and barley
(CIMMYT, 1979)
In 1950 a stem rust epidemic struck the wheat crop in the United States and Canada, reaching its greatest destruction in 1954. In 1953 the durum wheat crop of the U.S. was 60 per cent destroyed, and in 1954,75 per cent. ...
Article
Resistance of tomato plant genotypes with high foliar allelochemical contents to the leafminer Liriomyza trifolii = Resistência de genótipos de tomateiro com altos teores de aleloquímicos nas folhas à mosca-minadora Liriomyza trifolii
(Zeppelini Editorial, 2017)
The objective of this study was to assess the resistance of tomato genotypes with high foliar levels of allelochemicals to the leafminer Liriomyza trifolii. Eight tomato genotypes with contrasting levels of three different ...
Article
Controlling foliar blights of wheat in the rice-wheat systems of Asia
(American Phytopathological Society (APS), 2004)
Foliar blight caused by Cochliobolus sativus and Pyrenophora tritici-repentis is the main biotic stress of wheat in the rice-wheat systems of South Asia, where it causes, on average, up to 15% yield loss. Increases in food ...
Article
Wheat quality improvement at CIMMYT and the use of genomic selection on it
(Elsevier, 2016)
The International Center for Maize and Wheat Improvement (CIMMYT) leads the Global Wheat Program, whose main objective is to increase the productivity of wheat cropping systems to reduce poverty in developing countries. ...
Article
Association mapping of North American spring wheat breeding germplasm reveals loci conferring resistance to Ug99 and other African stem rust races
(BioMed Central, 2015)
Background: The recently identified Puccinia graminis f. sp. tritici (Pgt) race TTKSK (Ug99) poses a severe threat to global wheat production because of its broad virulence on several widely deployed resistance genes. ...
Article
Estimation of physiological genomic estimated breeding values (PGEBV) combining full hyperspectral and marker data across environments for grain yield under combined heat and drought stress in tropical maize (Zea mays L.)
(Public Library of Science, 2019)
High throughput phenotyping technologies are lagging behind modern marker technology impairing the use of secondary traits to increase genetic gains in plant breeding. We aimed to assess whether the combined use of ...
