Each of the current classifications varies in either or both genus and species concepts. Other generic concepts also exist. The diploid T-genome species can either be treated as Ae. As the following examples will show, species treatment is complicated by the various taxonomic approaches for constructing wheat classifications as well as by nomenclatural mistakes. These inconsistencies in taxonomic treatment affect all members of the wheat research community.
Communication is difficult when everyone is speaking a different language.
Genebank managers are often unclear on what germplasm is being requested when the researcher is following a taxonomic system different from that followed by the genebank. Misunderstanding of the taxonomic concept behind a species name can lead to mistakes in the selection of taxa to study. In the literature, researchers frequently fail to specify the classification they are following. There is also the problem of researchers who fail to follow any taxonomic treatment by arbitrarily choosing names without regard to classification. This situation presents a time-consuming, and often confusing, task for those who wish to decipher the exact identity of taxa reported in research articles.
