Understanding the genetic mechanisms controlling yield and quality in wheat

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
The majority of characters of agronomic importance in crop species, including yield and end use quality, show continuous variation where 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 project also targets comparative analysis between wheat and other cereal and model species to integrate the genetics of all the major cereal crops into a common framework.

| Description | New wheat genomic regions have been identified, which control plant height. Plant height is a proxy for biomass and via that, partly for yield. Ideal plant height is also a breeding target in it's own right, as it makes plants more robust against adverse weather conditions and thus protects yield. Genetic markers for height in- and decreasing loci have been identified which will help to breed ideal varieties for different environmental conditions. These markers have been used in plant breeding. New phenology genes and QTL have been shown to effect spike fertility and so grain number. |
| Exploitation Route | Genetic markers and information of the effects of genomic regions can be used in breeding new varieties with increased fertility. |
