The Great Basin region of the United States has a long history of large-scale revegetation and restoration seedings that require seed amounts well in excess of what would be available through direct wildland collections. To meet this seed need a number of research programs have arisen that develop plant materials suited to agronomic production and large-scale use. A few of these programs have existed for nearly a century. For much of this time only a handful of approaches to plant material development were implemented, focused primarily on selecting for sources and traits that supported seed production and ungulate forage value. However, additional development approaches have been established more recently that broaden the range of options for seed producers and restoration practitioners. These include more systematic source selection through the use of seed transfer zones and phylogeography, and a greater focus on traits that support long-term population persistence and growth in the wild. This talk will focus on the history of plant material development in the Great Basin and compare across approaches within the context of current production and restoration goals.
