Sugar beets and related wild species – from collecting to utilisation
HYPERLINKTab.1: Taxonomy of the genus Beta
long as descriptive databases are incomplete it is essential to document the synonyms
of accepted names in parallel.
LANGE et al. (1999) mentioned another problem. LETSCHERT (1993) treated wild species
of section Beta, only, and explicitly did not deal with the weedy and cultivated
material. As a result, there is no formal link between the wild and cultivated classification
system and no possibility to classify weedy types. It is therefore difficult to develop
a determination key for the whole genus as noticed by FRESE et al. (2001). In
addition to taxonomic problems of Beta section Beta, more research is required to
consolidate the taxonomy of section Corollinae. BUTTLER (1977) in his thorough revision
of section Corollinae could not deal with the hybrid complex in detail nor could
he validate the existence of a B. foliosa in Turkey. Section Procumbentes might also
need a revision since there are indications that B. webbiana and B. procumbens are
closely related if not even identical species (WAGNER et al. 1989). Furthermore, there
