Transcript

  • 1. Integrated Breeding Workflow System Update GCP General Research Meeting September 27 – 30, 2013 Lisbon, Portugal
  • 2. IBWS Update  What has happened since the last meeting?  Analytical Pipeline  Breeding View (GenStat and R versions)  Decision support tools  OptiMAS  Molecular Breeding Decision Tool (backcrossing)  GDMS – genotyping data management system  Genotyping support services (GSS)
  • 3. Analytical Tools  Breeding View – GenStat  Current pipelines  Single environment field trial analysis  GxE analysis  QTL linkage analysis
  • 4. Breeding View GenStat Pipelines  Breeding View - GenStat Pipelines  Single environment field trial analysis  Analysis for row-column designs including spatial analysis  Run multiple traits simultaneously  Automatic generation of diagnostic plots  Options added to control layout of report  Integration in IBWS
  • 5. Breeding View GenStat Pipelines  Single trait linkage analysis (QTL)  Run multiple traits simultaneously  Improved output, including graphics (e.g., profile plots)  Additional output file containing QTL results  GxE/multi-site analysis  Includes FW regression, AMMI, GGE biplots and stability coefficients  Run multiple traits simultaneously  Select environments  IBWS integration (input only)
  • 6. What is planned for Breeding View  Enhancement of existing pipelines  Sequential analysis of a series of environments in SSA pipeline  Implementation of additional pipelines  Field design generation pipeline  Genomic selection pipeline  QTLxE  Update installation program to include Breeding View – R  Same interface, same output files  SSA pipeline already implemented  Initial implementation of GxE pipeline  Enhanced integration in IBWS  Improvements/changes in the reporting of results
  • 7. OptiMAS  Improvements to OptiMAS algorithms to reduce calculation time and memory consumption  Previous analyses can be reloaded with chosen with previous configuration/preferences  Marker QC step to check for inconsistencies in genotyping  Improvements to the website including online and offline (within software) documentation and tutorial.
  • 8. What is planned for OptiMAS  Full integration into IBWS  Development of a wizard for automated decision making (selection of crosses).  Computation of diversity score based on the pedigree or markers.  Inclusion of QTL position uncertainty in score computation  Use of allele effects at QTL in order to compute expected gain for different traits and possibility to weight different traits to compute indexes.
  • 9. Molecular Breeding Decision Tool (MBDT)  Selection of polymorphic markers including those linked to chosen trait and export of list to a text file between parental lines.  Improvements to calculation of % recovery recurrent parent. Export function added to export the list of genotypes.  Be able to view individual chromosomes.  Option added to prioritize recombination (heterozygotes) at a flanking marker over percentage of recovery  Partial integration into the IBWS  Be able to use different marker types (i.e. combination of SSR and SNP markers)
  • 10. What is planned for MBDT  Full integration into IBWS  Enhancements to UI display (e.g. similar flapjack format)  Include unmapped markers
  • 11. Genotyping data management system (GDMS)  Select polymorphic markers between two lines (including trait specific markers) and export as genotyping order form  Improvements made in importing genotyping data direct into GDMS  Tools to help in the selection of parental lines  Select set of lines and send to flapjack for visualization, including unmapped markers  Investigate relationships among selected germplasm by calculating similarity matrix direct from GDMS
  • 12. What is planned for GDMS  Implement the new interface for GDMS  Enhance functionality to help in parental selection  Relatedness; Trait specific markers; visual selection of polymorphic markers  Further integration in the IBWS to improve the uploading of genotyping datasets  Enhance the selection of diagnostic markers and display of results for progeny selection in a MAS experiment  Implement additional QC steps  Ability to edit part of a dataset
  • 13. Conclusion  Following the first release of the IBWS  Enhancements in functionality of tools have continued and will continue  Better integration (retrieval and saving of data)  Series of user feedback sessions being conducted with breeders  Identify any gaps in current functionality or changes in existing functionality  Refactor the entire IBWS interface to improve the user experience
  • 14. IBP marker services  The new marker services concept based on high-throughput SNP genotyping was operational in 2011  Decision to focus on a single SNP genotyping provider (KBioscience, UK)  SNP conversion to KBioscience platform with  1,000-2,000 SNPs for each crop of interest  SSR genotyping support still being provided by current labs as needed  BecA  ICRISAT
  • 15. SNP markers at GCP
