The goal of this research is to determine the inheritance of 2,4-D and dicamba resistance in Palmer amaranth through classical genetic approaches. Understanding the genetic basis of herbicide resistance is important to formulate viable weed management strategies to delay herbicide resistance evolution. If the outcome suggests that a single, nuclear, dominant gene confers 2,4-D or dicamba resistance in Palmer amaranth, then resistance can spread faster compared to a recessive trait. If the results suggest that resistance is a multi-genic trait, then weed management practices are recommended to reduce the spread of resistance.
