configuration/preferences

 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

14. 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

15. 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
