Herbicide resistance in imported lines of ryegrass

<p dir="ltr"><b>Background</b></p><ul><li>200-400 tonnes of ryegrass imported per year</li><li>$80+ million NZD ryegrass multiplication industry</li><li>Resistant ryegrass common in arable sector</li><li>Farmers suspected resistant plants may come from imported seed for sowing</li></ul><p dir="ltr"><b>Goals</b></p><ul><li>Determine if imported lines of ryegrass have herbicide resistant phenotypes at rates higher than expected.</li><li>Develop genetic sequencing methods for detecting multiple resistance alleles in seed lots. (- not completed -).</li><li>Determine if some weed contaminants in imported seed lines are herbicide resistant</li></ul><p></p>
