Abstract/Contents:"Poa annua L. (annual bluegrass) is a ubiquitous weed species that has commonly been identified as one of the worst weeds to control in turfgrass systems. The increasing numbers of herbicide resistant populations is a major contributor to the difficulties faced in managing P. annua. With reported resistance to now 12 modes of action, the need to understand how to manage P. annua is at an all time high. Understanding how herbicide resistance is actually spread in P. annua could allow us to update our current management practices. Thus, a population study focusing on the genetic relatedness between resistant P. annua populations was conducted in order to ascertain how these populations were acquiring resistance traits. A selection of 144 individuals resistant to ALS, EPSPS, a-tubulin, and photosystem II herbicides were collected across the southeastern United States to analyze if there was a significant difference between populations. SSR markers were used to produce polymorphic bands, which were scored and used to determine population structure using STRUCTURE. The analysis resulted in a population structure of k=5, with seemingly no correlation between location or resistance type. This begs the question, how are these populations related, and what else do we need in order to understand how herbicide resistance is spread?"
