South East European (SEE) viticulture partially relies on native grapevine varieties, previously scarcely described. In order to characterize old local grapevine varieties and assess the level of synonymy and genetic diversity from SEE countries, we described and genotyped 122 accessions from Albania, Federation of Bosnia and Herzegovina (B&H), Croatia, Macedonia, Moldova, Montenegro, Republika Srpska (Bosnia and Herzegovina) and Romania on nine

Assessment of the genetic relatedness of walnut cultivars with phenotypic data and molecular markers allows progress in conservation and management of the genetic resources, breeding and protection of breeders’ intellectual property. In the present study we used 24 morphological traits, 25 random amplified polymorphic DNAs (RAPDs) and 7 simple sequence repeats (SSRs), to study genetic diversity and relationships in walnut cultivars at different

Prohexadione-Ca (ProCa) was applied in an adult walnut orchard of cv. Franquette to test its ability to reduce severity of Xanthomonas arboricola pv. juglandis (Xaj) infection, and the effect on the contents of phenolic compounds in walnut fruits. ProCa was used three times over at 8-10 day interval, starting before the stigmas emergence at 0.125 mg l-1 concentration (treatment R1), and at the stage of brown stigmas at 0.250 mg l-1 concentration
