Transgenic plants for mitigating introgression of genetically engineered genetic traits

A method to provide a mitigation to effects of introgression of at least one advantageous genetically engineered trait to an uncultivated interbreeding species related to the transformed cultivated crop, the method comprising transforming a population of plants of the cultivated crop to co-express the at least one advantageous genetically engineered trait, and at least one mitigating genetic trait, wherein:

• said at least one advantageous genetic trait is encoded by an advantageous gene conferring a trait selected from the group consisting of herbicide resistance, disease, insect and nematode resistance, environmental stress resistance, high productivity, modified agronomic quality, enhanced yield, modified ripening, bioremediation, expression of heterologous products and genetically modified plant products;
• said at least one mitigating genetic trait is encoded by a mitigating gene, said mitigating gene being an anti-shattering gene, an anti-bolting gene or a dwarfism gene;
• said advantageous gene and said mitigating gene having a genetic distance of no greater than 10 centimorgans from each other so as to produce tandem introgression of said advantageous and said mitigating traits into said uncultivated interbreeding species;
• and
• wherein introgression and expression of said mitigating genetic trait in said uncultivated interbreeding species related to the cultivated crop renders said uncultivated interbreeding species less fit compared to a similar uncultivated interbreeding species related to the cultivated crop and not expressing said mitigating genetic trait.
