The ploidy of perennial ryegrass, Lolium perenne, was studied in order to assess the potential of tetraploidity as a means of preventing transgenes from spreading to natural populations.In contradiction to earlier observations, we found that tetraploid L. perenne genotypes was present in a semi-natural habitat in non-trivial proportions. Consequently, we conclude that tetraploidy will not prevent GM traits from spreading to natural rye grass populations by either an invasion or an introgression pathway.
