Heat and drought adaptive QTL in a wheat population designed to minimize confounding agronomic effects
(Springer, 2010)
A restricted range in height and phenology of the elite Seri/Babax recombinant inbred line (RIL) population makes it ideal for physiological and genetic studies. Previous research has shown differential expression for yield ...
Article
Does ear C sink strength contribute to overcoming photosynthetic acclimation of wheat plants exposed to elevated CO2?
(Oxford University Press; Society for Experimental Biology, 2011)
Wheat plants (Triticum durum Desf., cv. Regallo) were grown in the field to study the effects of contrasting [CO2] conditions (700 versus 370 ìmol mol−1) on growth, photosynthetic performance, and C management during ...

META: A suite of sas programs to analyze multienvironment breeding trials
(American Society of Agronomy, 2013)
Multi-environment trials (METs) enable the evaluation of the same genotypes in a variety of environments and management conditions. We present here META (Multi Environment Trial Analysis), a suite of 31 SAS programs that ...

Microsatellite markers for genes Lr34/Yr18 and other quantitative trait loci for leaf rust and stripe rust resistance in bread wheat
(American Phytopathological Society (APS), 2003)
Leaf rust and stripe rust, caused by Puccinia triticina and P. striiformis, respectively, are important diseases of wheat in many countries. In this study we sought to identify molecular markers for adult plant resistance ...

Genetics of leaf rust resistance in brambling wheat
(American Phytopathological Society (APS), 2008)
The CIMMYT-developed spring wheat ‘Brambling’ has a high level of adult-plant resistance (APR) to leaf rust caused by Puccinia triticina. Our objectives were to determine the genetic basis of resistance in ...

Characterization of seedling infection types and adult plant infection responses of monogenic Sr gene lines to race TTKS of Puccinia graminis f. sp. tritici.
(American Phytopathological Society (APS), 2007)
Stem rust, caused by Puccinia graminis f. sp. tritici, historically was one of the most destructive diseases of wheat and barley. The disease has been under effective control worldwide through the widespread use of host ...
Article
Identification of a microsatellite on chromosome 7B showing a strong linkage with yellow pigment in durum wheat (Triticum turgidum L. var. durum)
(BioMed Central, 2001)
The objective of this study is to identify QTLs linked to yellow pigment content in durum wheat. A durum‐dicoccoides genetic linkage map was constructed using 124 microsatellites, 149 amplified fragment length polymorphism ...
Article
Increasing wheat yields sustainability through agronomic means
(CIMMYT, 1998)
This paper examines common factors that constrain wheat yields: insufficient nutrients (using nitrogen as an example); problems of late planting and poor crop establishment; suboptimal water management; lodging; and weeds. ...
Article
Genetic association mapping identifies single nucleotide polymorphisms in genes that affect abscisic acid levels in maize floral tissues during drought
(Oxford University Press; Society for Experimental Biology, 2011)
In maize, water stress at flowering causes loss of kernel set and productivity. While changes in the levels of sugars and abscisic acid (ABA) are thought to play a role in this stress response, the mechanistic basis and ...

Genetic diversity of the mating type and toxin production genes in Pyrenophora tritici-repentis
(American Phytopathological Society (APS), 2010)
Pyrenophora tritici-repentis, the causal agent of tan spot on wheat, is a homothallic loculoascomycete with a complex race structure. The objectives of this study were to confirm the homothallic nature of the pathogen, ...
