Abstract

The potential for the adaptation of wheat to UK environments has been constrained by the framework of the pedigree selection method that has dominated plant breeding for a century. UK pedigree line breeding may have imposed limits on the performance of wheat, particularly with respect to environment buffering, thus increasing the need for synthetic inputs. This research will identify traits or sets of traits that determine or improve adaptation of wheat to the range of UK arable environments, production systems and markets using composite cross populations of wheat based on a wide range of key parent varieties. The parents will be selected partly on past knowledge of successful performance in terms of yield, quality and disease resistance and partly on the basis of molecular ancestry to try to ensure as wide range of diversity as possible. Following parental inter-crossing in all possible combinations, progeny population samples will be exposed to a range of widely different agricultural environments and systems through several seasons of, largely, natural selection. Performance of the population samples will be compared at different stages against both the parents grown as pure stands and as physical mixtures. The research will deliver a unique insight into the evolution of a genetically diverse wheat population in a diverse range of environments. This will provide information on the characters of winter wheat that confer improved performance within each environment.
