| Abstract/Contents: | "Several genes of resistance to herbicides that control grasses (Ignite or bialophos; Pursuit, and imidazolinone) have been introduced into cell lines of various cultivars of creeping bentgrass (Agrostis plaustris Huds). Two methods were used-protoplast transformation and the gene gun. Green house and field trials of clonally propagated plants regenerated from the cell lines show useful resistance. Tests of seeds from transgeneic mother plants carrying the bar gene pollinated by normal bentgrass in a containment greenhouse show that resistance to Ignite is transmitted to the next generation. These transgeneic bentgrass lines are of potential interest to breeders and greenskeepers since they offer a simple means of controlling such grass weed as Poa annua. There are two concerns, one scientific the other economic, that now limit the percived value of herbicide resistant turfgrass. Creeping bentgrass is not an important weed in agriculture although it is a weed in bluegrass lawns. The risk of horizontal spread of herbicide resistance to other species and genera that are weeds is seen as a potential drawback that could limit the usefulness of herbicide resistance in major field crops. In fact,A. Palustris is not known to be sexually compatible to with A. alba and A. scabra or with other genera such as Eragrostis. The second concern questions the size of the potential market for herbicide sales to greenskeepers or of royalty returns on seed sales. These are admittedly small in comparison to the major crops but are nevertheless locally important and could be rewarding if the forms were widely adopted." |
