Fitomejoramiento fisiológico I: enfoques interdisciplinarios para mejorar la adaptación del cultivo
Este manual de dos tomos sobre Fitomejoramiento Fisiológico ha sido desarrollado en respuesta a la demanda por parte de colegas en todo el mundo que trabajan en distintas áreas de la investigación de cultivos, desde el ...
Cultivo intercalado de cereales con especies de leguminosas que fijan N: un metodo para conservar los recursos del suelo en sistemas de bajos insumos
La producción de cereales con pocos insumos y gran eficiencia contribuye a aliviar la pobreza, incrementa los ingresos agrícolas y favorece la conservación del medio ambiente (1os suelos y el agua). Este Informe Especial ...
Genome-wide comparative diversity uncovers multiple targets of selection for improvement in hexaploid wheat landraces and cultivars
(National Academy of Sciences, 2013)
Domesticated crops experience strong human-mediated selection aimed at developing high-yielding varieties adapted to local conditions. To detect regions of the wheat genome subject to selection during improvement, we ...
Evaluation and interpretation of interactions
(American Society of Agronomy, 2013)
Understanding the factors that define a given interaction is important in agricultural, agronomic, and plant breeding research, where agronomic treatments or genotypes are evaluated under several environmental conditions ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
