KITCHEVA, P., Ya. GUTEVA and S. ANGELOVA, 2003. Evaluation of the genetic diversity of Bulgarian germplasm vetch collection. Bulg. J. Agric. Sci., 9: 33–37

The vetch collection, which is stored and maintained in the genebank of IPGR – Sadovo, is notable for its diversity of species, origins and type of the materials. The considerably presence of local origins (60–70 %) defined it as a very unique. The current objective of this study is to evaluate the significant potential of vetch germplasm with Bulgarian origin – local populations, old cultivars and wild forms of common vetch, for important agrobiological characters and the reaction of different Vicia L. species to biotic and abiotic stress factors. A complex systematic characterization study of local vetch accessions from the National Plant Genetic Resource collection is presented for a first time. During the last two years (1999–2001) 100 accessions of common vetch (Vicia sativa L.) and 28 accessions, belonging to other 8 annual Vicia L. species were evaluated about 38 morfological and economic characters. The vegetation period was established both under in spring and autumn sowing. The reaction of different Vicia L. species to low negative temperatures and to the pathogen Fusarium culmorum was studied. The sources of resistance can be found in the following species: Vicia villosa Roth., Vicia sativa ssp. angustifolia Grufb., Vicia grandiflora Scop., Vicia lutea L., Vicia pannonica Crantz. ssp. pannonica and ssp. striata.
