Taxonomic studies on the close wild relatives of the faba bean (Vicia faba L.) in section Faba

Khattab, Adel Mahmoud Attia (1987) Taxonomic studies on the close wild relatives of the faba bean (Vicia faba L.) in section Faba. University of Southampton, Doctoral Thesis.

Abstract

The aim of this study was to produce a classification reflecting the relationships between the wild species of V.narbonensis complex and the cultivated faba bean (V.faba L.). To provide a background and to clarify the problems associated within V.narbonensis complex the taxonomic histories of the tribe Vicieae, the genus Vicia and section Faba were reviewed. Investigations of the variation patterns were made using morphological, chemical, geographical and cytological sources of data. The phenetic method of analysis (single linkage clustering) has been used to analyse the morphological data. The brief results obtained by using this method are: all the species known as the V.narbonensis complex are more similar to each other than to either V.faba or V.bithynica. The species defined as V.johannis and V.serratifolia are very distinguishable and distinct from each other and from V.narbonensis. The species V.hyaeniscyamus has many morphological characters different from the rest of V.narbonensis complex, and is also distinct. A new population found in Syria in 1986 is a new species. V.faba is isolated from the rest of the species. Finally, V.bithynica has several different features when compared with V.faba or V.narbonensis complex. The proposed classification, synonymy, descriptions and a key to taxa in section Faba are presented. (D81290)
