Research Project: PEDIGREE BASED ASSOCIATION ANALYSIS OF NOVEL SOURCES OF FHB RESISTANCE IN DURUM WHEAT Project Number: 0500-00053-002-98
Project Type: Grant

Start Date: May 05, 2009
End Date: May 04, 2014

Objective:
Explore an alternative strategy to not only quickly map the region of interest from multiple sources but do this in breeding populations under development. This strategy is intended to reduce the time required for QTL identification and marker assisted selection significantly. Use this collection of backcross derived advanced resistant lines, susceptible sibs, and parental lines to identify markers that are associated with these novel sources of resistance. The elegance of this analysis is the integration of derived information directly into the breeding programs for verification and future marker assisted selection and pyramiding of resistance loci.

Approach:
Characterize a collection of advanced durum wheat breeding lines with known pedigrees for allelic variation in markers distributed throughout the genome; characterize the same collection of lines in the same environment for reaction to FHB; associate allelic variation with resistance loci present in FHB resistant lines; and develop diagnostic markers for routine and effective screening of breeding populations.
