Abstract From the Canadian patent

The present invention relates to a novel process for inserting genetic material into monocotyledonous plants or viable parts thereof, which is characterised in that transfer microorganisms that are capable of inserting the said genetic material into monocotyledonous plants or viable parts thereof and that contain the genetic material to be inserted in a transportable form are inoculated in the form of a bacterial suspension into a meristematic tissue region of the plant or of a viable part thereof. By suitable selection of the time of application from the point of view of the stage of development of the recipient plant it is possible to increase the transformation frequency even further.
