QTL for yield and associated traits in the Seri/Babax population grown across several environments in Mexico, in the West Asia, North Africa, and South Asia regions
Heat and drought adaptive quantitative trait loci (QTL) in a spring bread wheat population resulting from the Seri/Babax cross designed to minimize confounding agronomic traits have been identified previously in trials ...
Association mapping and nucleotide sequence variation in five drought tolerance candidate genes in spring wheat
Functional markers are needed for key genes involved in drought tolerance to improve selection for crop yield under moisture stress conditions. The objectives of this study were to (i) characterize five drought tolerance ...
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 ...
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 ...
Food security and climate change: on the potential to adapt global crop production by active selection to rising atmospheric carbon dioxide
Agricultural production is under increasing pressure by global anthropogenic changes, including rising population, diversion of cereals to biofuels, increased protein demands and climatic extremes. Because of the immediate ...
Physiological traits for improving heat tolerance in wheat
Wheat (Triticum aestivum) represents about 30% of the world?s cereal area, with over 220 million ha cultivated worldwide, often under abiotic stress. Wheat growth can be impaired by heat stress (HS) at any developmental ...
Proceedings of the 2nd International TRIGO (Wheat) Yield Potential : workshop 2016
(CIMMYT; USAID; MASAGRO; SAGARPA; CONACYT, 2016)
Achieving yield gains in wheat
Wheat provides 20% of calories and protein consumed by humans. Recent genetic gains are <1% per annum (p.a.), insufficient to meet future demand. The Wheat Yield Consortium brings expertise in photosynthesis, crop adaptation ...
