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 ...
Stay-green in spring wheat can be determined by spectral reflectance measurements (normalized difference vegetation index) independently from phenology
(Oxford University Press; Society for Experimental Biology, 2012)
The green area displayed by a crop is a good indicator of its photosynthetic capacity, while chlorophyll retention or ?stay-green? is regarded as a key indicator of stress adaptation. Remote-sensing methods were tested to ...
Improving crop adaptation to climate change through strategic crossing of stress adaptive traits
Crossing programs based on phenomics have resulted in a new generation of drought adapted wheat lines based on strategic crossing of complementary physiological traits (PT) that have been included in CIMMYT's international ...
Food security through translational biology between wheat and rice
(Wiley Open Access; Association of Applied Biologists, 2015)
Wheat and rice are the most important food crops in agriculture providing around 50% of all calories consumed in the human diet. While both are C3 species, the evolution and domestication of wheat and rice occurred in very ...
Foliar abscisic acid-to-ethylene accumulation and response regulate shoot growth sensitivity to mild drought in wheat
Although, plant hormones play an important role in adjusting growth in response to environmental perturbation, the relative contributions of abscisic acid (ABA) and ethylene remain elusive. Using six spring wheat genotypes ...
Canopy temperature and vegetation indices from high-throughput phenotyping improve accuracy of pedigree and genomic selection for grain yield in wheat
(Genetics Society of America, 2016)
Genomic selection can be applied prior to phenotyping, enabling shorter breeding cycles and greater rates of genetic gain relative to phenotypic selection. Traits measured using high-throughput phenotyping based on proximal ...
Strategic crossing of biomass and harvest index—source and sink—achieves genetic gains in wheat
To accelerate genetic gains in breeding, physiological trait (PT) characterization of candidate parents can help make more strategic crosses, increasing the probability of accumulating favorable alleles compared to crossing ...
Genome-wide association study for adaptation to agronomic plant density: a component of high yield potential in spring wheat
(Crop Science Society of America (CSSA), 2015)
Previous research has shown that progress in genetic yield potential is associated with adaptation to agronomic planting density, though its genetic basis has not been addressed before. In the current study, a wheat (Triticum ...
Genetic dissection of grain size and grain number trade-offs in CIMMYT Wheat Germplasm
(Public Library of Science, 2015)
Grain weight (GW) and number per unit area of land (GN) are the primary components of grain yield in wheat. In segregating populations both yield components often show a negative correlation among themselves. Here we use ...
Genomic prediction of gene bank wheat landraces
(Genetics Society of America, 2016)
This study examines genomic prediction within 8416 Mexican landrace accessions and 2403 Iranian landrace accessions stored in gene banks. The Mexican and Iranian collections were evaluated in separate field trials, including ...
