| Abstract/Contents: | "Yellow nutsedge (Cyperus esculentus L.) is a common weed in crop production, landscapes, and turfgrass. Use of molecular markers over different scales of sample collections has been shown to uncover different levels of genetic variability in yellow nutsedge. Investigating the genetic variability in yellow nutsedge will help to better understand whether new infestations occur through sexual or asexual reproduction. Our objective was to compare the amount of genetic diversity of yellow nutsedge clones collected within populations with those collected among distinct populations. Amplified fragment length polymorphism (AFLP) was used to compare the amount of genetic diversity among 25 yellow nutsedge samples collected from four locations at a local golf course in Lincoln, NE and the amount of genetic diversity of samples collected from Mead, NE, Manhattan, KS, Falcon Heights, MN, West Lafayette, IN, and cultivated chufa (C. esculentus var. chufa). Genetic variability within populations was found to be lower than the genetic variability among distinct populations. Our results suggest that asexual reproduction was likely the primary means of infestation at the particular golf course where samples were collected due to the observed low genetic variability. Sexual reproduction via seed dispersal is a possible means of yellow nutsedge infestation over a long distance." |
