As herbicide resistance continues to spread, this project aims to determine the heritability of HPPD resistance in common waterhemp. It will also explore if hybridization is common between common waterhemp and Palmer amaranth. Seed variability resulting from greenhouse studies of weed seed will uncover if postzygotic reproductive barriers exist which could impact the field establishment of these types of weeds.
