CURRENT SITUATION

Figure 1. Schematic of the Haplotype Effort

Identify additional SNPsin gene or QTL containing

regions

Haplotype QTL containingregions in known sources

of positive allele

Confirm QTL regions Study allelic diversity

Fine map QTL regions (when possible)

Haplotype all known germplasm that is positive for the trait

Make crosses with sourcesthat have a high potential

for having new alleles

Conduct genetic mappingin the sources with

potentially novel alleles

Identify sources of novel alleles, initiate breeding for QTL

Build genotyping kits; deliver through the SBT &regional genotyping centers
