Classification of Triticum according to Gandilyan 1980.

Gandilyan's [reference] contributions to wheat taxonomy are largely unknown outside of Armenia and the countries of the former USSR due to the language barrier. Although this 1980 key to Triticum is not a true classification, it does offer the views of this important contemporary triticologist. His taxonomic concept of Triticum is morphologically based, emphasizing reproductive traits. Gandilyan only deals with 21 species. Seven other species, including two synthetic forms, are mentioned but not treated as part of his key. Gandilyan's classification is presented here in its original form with corrections in spellings, nomenclature, and authority citations.
