Abstract
Grass identification traditionally relies on morphological examination of floral material, and often requires specialist knowledge of morphological characteristics diagnostic for the various genera and
species. DNA barcoding may provide a rapid genetic screening tool to identify selected noxious grass weeds at the vegetative growth stage. We tested the utility of 18 chloroplast and nuclear genes as potential DNA barcodes for species identifications of introduced grasses present in Eastern Australia. Grasses examined (N = 417) included Nassella neesiana (Trin. & Rupr.) Barkworth (Chilean needle grass), Nassella trichotoma (Nees) Hack. ex Arechav. (serrated tussock), Eragrostis curvula (Schrad.) Nees (African love grass) and 26 other weed species collected from New South Wales (NSW), Australian Capital Territory (ACT) and other parts of Australia. Our preliminary results revealed
three chloroplast genes, matK, ndhK and petL, which exhibit potentials as DNA barcodes for distinguishing and identifying weeds species of interest.
