Abstract

To be officially registered and therefore to acquire the right to be called “a cultivar”, any newly bred common wheat genotype must pass a series of tests to confirm that it fits three requirements (called “DUS”-it must be genetically Distinct, Uniform and Stable). One of the more important of these requirements is that the candidate cultivar should be composed of genotypically identical homozygous individuals (seeds, plants). Thus, SW genotypic uniformity is one of the more important definitions of the officially registered cultivar [1]. The DUS procedure provides a basis for protecting the intellectual property of the breeder for a given cultivar [1-3].
