Plant Breeders’ Rights (PBR)
Some crop varieties used in research trials may be covered by Plant Breeders' Rights (PBR). Users should confirm PBR status of relevant varieties by searching the IP Australia PBR database, http://pericles.ipaustralia.gov.au/pbr_db/ or Variety Central (http://varietycentral.com.au/) and contacting variety owners for further information if required. Where possible, varieties have been listed according to their registered PBR name, although OFT cannot and does not guarantee that the information is accurate or complete.
