The aim of WP4 is to apply the resources and knowledge generated in the other WPs to improve the efficiency of molecular breeding in wheat and barley. It is developed by Beneficiaries of the project that belong to leading breeding companies and institutes in Europe. WP4 will use the different types of markers and genomic information that will be generated in WP1, 2 and 3 to develop markers and to identify new loci for breeding traits of interest that are located on chromosomes of group 1 and 3.
The ultimate goal is to use these markers to create new varieties that meet consumer needs (e.g. quality, sustainable production) through marker-assisted selection (MAS).
At the end of the last project year, WP4 performed association studies to identify traits of agronomic interest and develop molecular markers linked to these traits for supporting the creation of new varieties by marker-assisted selection using a panel composed of 376 winter wheat varieties from France, the UK, Germany maximizing the phenotypic and genetic diversity of the European material. The panel was evaluated for yield and development related traits at 3 locations over 2 years and was genotyped with DArT markers, markers for major adaptation genes and SNP markers derived from COS developed in WP2. Genome-Wide Association Analyses were conducted for heading date, grain yield and plant height. Known and new chromosomal locations were identified. The TG panel has been multiplied for distribution to partners by NIAB.
