Abstract

Silphium integrifolium is a long-lived perennial prairie plant undergoing domestication and has the potential to act as an oilseed and forage crop while providing ecosystem services to growers. This dissertation characterizes diverse populations of S. integrifolium for traits related to pest resistance, pathogen ecology in wild populations, and adaptation of wild S. integrifolium populations to biotic stressors. The investigation of wild silflower populations informs the next steps of the domestication process, allows S. integrifolium breeders to overcome current barriers as well as prepare for future challenges. These findings highlight the potential utility of wild populations and underscores the importance of characterizing and conserving S. integrifolium species prairie remnants.
