In bacteriological nomenclature "variety" is not allowed, but names published as varieties before 1992 are taken to be published as subspecies.
In 葡萄栽培 nomenclature, what is referred to as "grape varieties" are in reality 栽培品种s according to usage in the International Code of Nomenclature for Cultivated Plants or "plant varieties" in the legal sense rather than botanical taxonomy varieties, since they are propagated by 扦插 and have properties that are not stable under 有性生殖. However, usage of the term variety is so entrenched in viticulture that a change to cultivar is unlikely.
