Abstract
Abstracts are not currently available in GtR for all funded research. This is normally because the abstract was not required at the time of proposal submission, but may be because it included sensitive information such as personal details.
Technical Summary
Abiotic stress tolerance is genetically complex, displaying continuous variation because the effects of individual genes (so called Quantitative trait loci), cannot be discerned. The aim of this project is to deploy genetic and genomic tools to map and clone such genes. This is an essential prerequisite for understanding their modes of action and making them available as targets for genetic manipulation by plant breeders. The work has particular emphasis on wheat since this is the UK's most important agricultural crop. The work is focused on conditions where limited availability of nirogen and water reduces grain yield.

| Description | We have shown that delayed senescence can increase grain yield in wheat by increasing grain size. This is particularly effective in heat and drought stressed environments. We have produced perfect molecular markers for the causative mutations underlying this trait. |
