Abstract While an adequate supply of food can be achieved at present for the current global population, sustaining this into future will difficult in face a steadily increasing increased wealth and diminishing availability fertile land water agriculture. This problem compounded by new uses agricultural products, example, as biofuels. Wheat alone provides ≥20% calories protein world's value need to increase production is recognized widely. Currently, world average wheat yield around 3 t/ha...
Abstract Two field experiments were carried out with seven wheat cultivars (three of them, including a commercial hybrid, released during the last 10 years) representing different eras plant breeding, to evaluate genetic improvement over century in grain yield, height, biomass, harvest index and yield components. Plots fertilized irrigated, lodging diseases prevented. Main culm height was negatively correlated year release cultivars, probably as consequence selection for increased...
Grain weight is one of the most important components cereal yield and quality. A clearer understanding physiological molecular determinants this complex trait would provide an insight into potential benefits for plant breeding. In present study, dynamics dry matter accumulation, water uptake, grain size in parallel with expression expansins during growth wheat were analysed. The stabilized content grains showed a strong association final (r2=0.88, P <0.01). length was found to be that best...
Summary Wheat is the most widely grown crop globally, providing 20% of all human calories and protein. Achieving step changes in genetic yield potential crucial to ensure food security, but efforts are thwarted by an apparent trade‐off between grain size number. Expansins proteins that play important roles plant growth enhancing stress relaxation cell wall, which constrains expansion. Here, we describe how targeted overexpression α‐expansin early developing wheat seeds leads a significant...
Grain weight (GW) and number per unit area of land (GN) are the primary components grain yield in wheat. In segregating populations both often show a negative correlation among themselves. Here we use recombinant doubled haploid population 105 individuals developed from CIMMYT varieties Weebill Bacanora to understand relative contribution these their interaction with each other. was chosen for its high GW GN. The phenotyped Mexico, Argentina, Chile UK. Two loci influencing were indicated on...
Quinoa high nutritive value increases interest worldwide, especially as a crop that could potentially feature in different cropping systems, however climate change, particularly rising temperatures, challenges this and other species. Currently, only limited knowledge exists regarding the grain yield key traits response to higher temperatures of crop, increased night temperatures. In context, main objective study was evaluate effect temperature on quinoa yield, number, individual weight...
The effect of environmental conditions immediately before anthesis on potential grain weight was investigated in wheat at the experimental field Faculty Agronomy (University Buenos Aires, Argentina) during 1995 and 1996. Plants two cultivars were grown environments (two contrasting sowing dates) to provide different background temperature conditions. In these environments, transparent boxes installed covering spikes order increase spike for a short period ( c . 6 days) anthesis, i.e. between...
Grain weight is a trait which has hardly been exploited for raising genetic yield potential of wheat. A clearer understanding physiological determinants grain would be useful in establishing the value this future breeding programs. The objective study was to improve how intra-spikelet competition assimilates pre- and post-anthesis affect potential, evaluate possible mechanisms determining final Two experiments were carried out under field con-ditions. Proximal or distal grains from two...

SUMMARY Agricultural systems are challenged by global climatic change in a scenario of increasing food demand growing population. The increase average temperature will be the main environmental factor affecting crop development and productivity worldwide, although changes carbon dioxide (CO 2 ) concentration rainfall also expected. Global warming range moderately high temperatures (15–32°C) is projected for temperate environments such as that central-southern Chile, where grain crops wheat...
Abstract Wheat is the most widely grown food crop, with 761 Mt produced globally in 2020. To meet expected grain demand by mid-century, wheat breeding strategies must continue to improve upon yield-advancing physiological traits, regardless of climate change impacts. Here, best performing doubled haploid (DH) crosses an increased canopy photosynthesis from field experiments literature were extrapolated global scale a multi-model ensemble process-based crop models estimate production. The DH...
