Genome Wide Markers

• We have several initiatives to develop more
  efficient markers for genome wide mapping,
  comparative mapping, and building an oat
  consensus map
• DArT Marker Consortium
• Large numbers of low-cost markers for refining
  the KO map and rapidly mapping new crosses
• (details in Platform Presentation by Nick
  Tinker)
• SSR Markers
• New multi-allelic markers easily distinguish oat
  genotypes
• (details in poster by Charlene Wight, Wekai Yan,
  Jitka Deyl and Nick Tinker)

Target Specific Markers

• We have several initiatives to develop markers
  tagging specific loci for genetic studies and
  potential marker assisted breeding
• Mapping the Dw6 dwarfing locus using NILs
• Dw6, and Pc91, located to KO33 near PCR-based
  markers
• (details in poster by Steve Molnar, Julie
  Chapados, Bonnie Bancroft, and Solomon Kibite)
• SCAR and CAPS markers linked to quality traits
• 8 markers targeting oil content and 15 for
  b-glucan and protein content QTL regions
• (details in poster by Steve Molnar and Winson
  Orr)
