Genetic Constitution and Variability in Synthetic Populations of Intermediate Wheatgrass, an Out-crossing Perennial Grain Crop.

ABSTRACT: Intermediate wheatgrass (IWG) is a perennial grass that produces nutritious grain while offering substantial ecosystem services. Commercial varieties of this crop are mostly synthetic panmictic populations that are developed by intermating a few selected individuals. As development and generation advancement of these synthetic populations is a multi-year process, earlier synthetic generations are tested by the breeders and subsequent generations are released to the growers. A comparison of generations within IWG synthetic cultivars is currently lacking. In this study, we used simulation models and genomic prediction to analyze population differences and trends of genetic variance in four synthetic generations of MN-Clearwater, a commercial cultivar released by the University of Minnesota.
