Genetic Mapping of Quantitative Trait Loci Associated With Important End-Use Quality Parameters in the Winter Wheat (Triticum aestivum L.) Cross ‘Coda' x ‘Brundage 96'.

Wheat has many different end uses, each one requiring different quality parameters.  Due to the time constraints associated with milling and baking tests, understanding the quantitative nature of end-use quality traits as well as identifying molecular markers will allow breeders to more efficiently select wheat cultivars with superior end-use quality.  A set of 207 recombinant inbred lines (RIL) from a soft white wheat ‘Coda’ x ‘Brundage 96’ bi-parental mapping population was grown at three locations throughout the Pacific Northwest to identify quantitative trait loci (QTL) associated with end-use quality measurements including flour protein, flour yield, flour ash, milling score, break flour and cookie diameter.  JMPGenomics was used in the creation of the linkage map, consisting of 181 SSR markers and 1,494 SNP markers.  The constructed linkage map covers all 21 wheat chromosomes with the exception of 1D.  Significant QTL will be reported and presented. Identification of end-use quality QTL lays a foundation for wheat breeders to increase gains from selection by use of marker-assisted selection for these complex traits.
