Abstract
Flax (Linum usitatissimum L.) is a poor biological competitor and so requires chemical weed control for optimal productivity. An alternative to current, relatively expensive combinations of herbicides might be to introduce into a commercial flax genotype, using Agrobacterium mediated transformation, a gene conferring tolerance to a non-selective herbicide. Here, we describe the transformation of Norlin flax with a PAT (phosphinothricin acetyl transferase) gene conferring tolerance to glufosinate, a non-selective herbicide (Harvest™, Ignite™, Agrevo). We also present results from a preliminary field trial, showing the efficacy of the PAT gene in conferring tolerance while not dramatically altering the normal agronomic traits of the parent cultivar. Key words:Linum usitatissimum, flax, transgenic, glufosinate, phosphinothricin, field trial, herbicide tolerance
