Project Type: Reimbursable

Start Date: Oct 01, 2009
End Date: Aug 31, 2013

Objective:
1. Select progeny based on genomic selection (GS) and phenotypic selection and compare their performance in subsequent field trials. 2. Assess the ability of GS to predict the true breeding value of a parent 3. Determine whether a trained GS model maintains accuracy over cycles of breeding. 4. Use simulations to assess scenarios for the introduction and implementation of GS in a breeding program to optimize short- and long-term success over cycles of GS.

Approach:
Cooperating PI’s will run field experiments on sets of progeny to obtain phenotypic data; they will also extract DNA and obtain marker data. We will analyze these data using several genomic selection methods to generate predictions of breeding and genetic values based on marker data. In parallel, we will use these data and other data available from historical trials to estimate breeding and genetic values directly from phenotype and pedigree data. We will then correlate predictions with directly observed data to evaluate the accuracy of genomic selection.
