PROJECT 2 ABSTRACTArs Agreement • March 12th, 2014
Contract Type FiledMarch 12th, 2014Genomic selection (GS) is a promising new approach to marker assisted selection that uses large DNA marker and trait data sets to calibrate models that are used to predict the performance of breeding lines that have not undergone phenotypic evaluation. GS predicted genetic values of breeding lines can be used to select parents in early generations substantially shortening the breeding cycle from the four years that it typically takes with phenotypic selection to a single year. Given the relatively low heritability of FHB severity and DON concentration and the high cost of phenotyping these and other important traits, GS should be useful to accelerate efforts to breed resistance to FHB. The overall goal of this project will be to conduct two cycles of GS within the two year funding cycle to generate breeding lines that will be available for testing in the springs of 2015 and 2016. The major tasks to be carried out will be crossing of selected parents, advancing populations to the F2 and
