Some key dates of the project
The BreedWheat project is a 9-year project, thus allowing the characterization of populations developed in the project. Different events, results and resources mark the project progress, here is an overview:
The BreedWheat project is launched!
The BreedWheat Investments for the future project officially starts on Thursday 29th and Friday 30th September 2011 in Clermont-Ferrand, in the presence of its 28 partners, funders and the press
Selection of a panel of 4,600 wheat accessions representing global diversity
This sampling was carried out among the 11,960 bread wheat accessions coming from 108 countries and available at the INRA Auvergne Rhône-Alpes Small grain cereals Biological Resources Centre. The list of these accessions is available upon request to firstname.lastname@example.org
Design of a genotyping chip containing more than 420,000 SNP markers
BreedWheat designs one of the largest genotyping chips ever developed in wheat using Affymetrix's Axiom technology. Part of this chip, 280,000 SNP markers, is made available to the international scientific community.
Development of a platform for regulatory gene network inference
The RulNet platform allowing the inference of gene regulation networks (http://rulnet.isima.fr/) is developed (Vincent et al., 2015).
A new coordinator for the project
Catherine Feuillet who built this project and ensured its starting is leaving for new horizons. Jacques Le Gouis from INRA GDEC succeeds her as coordinator.
Production of genotyping data on more than 7,000 wheat lines
The BreedWheat genotyping chip allows genotyping more than 7,000 wheat lines comprising elite and exotic strains. This genotyping is carried out on the high-throughput genotyping platform, Gentyane, of the INRA Auvergne Rhône-Alpes center.
Development of a tool for genomic selection
A pipeline, called BWGS (BreedWheat Genomic Selection), based on R open libraries, is developed. It allows to test different methods to construct and validate genomic selection models.
An international conference brings together scientists from the wheat science community in Clermont-Ferrand
At the initiative of the BreedWheat project, an international conference called IWIW (International Wheat Innovation Workshop) is organized in Clermont-Ferrand on 16 and 17 November 2015. Details of the program, pictures and presentations are available on the website dedicated to this event: https://colloque.inra.fr/iwiw
The project is evaluated at mid-term
The members of the BreedWheat's international scientific committee evaluate the project progress at its 4th annual meeting. They are generally impressed by the advances made by the project.
Production of the annotated sequence of chromosome 1B
By sharing the sequence of chromosome 1B with the International Wheat Genome Sequencing Consortium (IWGSC), the BreedWheat project contributed to the production of the reference sequence of the whole wheat genome.
Construction of a genetic map comprising 307,270 loci
Genotyping data were used to construct a consensus genetic map comprising 307,270 loci, one of the highest density genetic maps ever produced in wheat.
Collection and formatting of phenotyping data from trials conducted in 2012, 2013 and 2014
Field trials were conducted, between 2012 and 2014, on 220 wheat varieties in 27 experiments related to nitrogen deficiency, resistance to drought and diseases. These data coupled with the genotyping data allow to carry out association analyses (GWAS).
Development of a carbon-nitrogen model
A carbon-nitrogen ecophysiological model able to simulate the post-flowering period of wheat is completed and evaluated against experimental data (Barillot et al., 2016A, Barillot et al., 2016b). The software is available on the SourceS platform upon request to the authors.
Selection of a diversity panel of 450 wheat accessions
A panel of 450 winter accessions is selected from the 4,600 lines representing global diversity. The list of these accessions is available upon request to email@example.com.
