Summary
Climate change threatens the food security of the world’s population because of its impact on the productivity and quality of agricultural crops, especially in vulnerable regions such as the Mediterranean. The use of nitrogen fertilizers has contributed to improved agricultural productivity, but their abuse can increase emissions of nitrogen oxides into the atmosphere, further contributing to climate change, as well as having detrimental environmental effects.
Ensuring food security and sustainable agriculture will require crop varieties that are better adapted to the future climate scenario under low-input conditions.
In this context, the assessment of natural genetic diversity in response to the combined increase in CO2 and temperature provides a powerful tool to explore the impact of climate change on wheat grain yield and nutritional quality and its dependence on nitrogen availability.
Therefore, the general objective of the project is (i) to evaluate the genotypic variability in the distribution of C-N assimilates in vegetative organs and their remobilization and translocation to the grain as a function of nitrate availability, and (ii) to determine how the genotype-environment relationship influences the deposition of carbohydrates, proteins and bioactive compounds in the mature grain.
The results may contribute to the selection of wheat varieties with better efficiency in the use of inputs, and generate innovative high quality products with interest for the agri-food sector industries. This research activity is framed within the thematic priority of Agri-Food and Natural Resources of the RIS3 of Castilla y León 2014-2020.
