Identification and examination of certain cytogenetic characteristics of some autochthonous varieties of grapevine in Republic of North Macedonia

In R.N. Macedonia has a large number of autochthonous or domestic varieties (cultivars) grapevine that are grown as individual vines in small, limited plantations. Until the beginning 20th century and before phylloxera attack our country, native were much more represented. Autochthonous existed cultivated for long time several vineyards characterized by stable significant properties. These adapted to environmental conditions where they carriers genes can be used further selection hybridization obtain new grape varieties. Therefore, it is very important country (region) have its assortment.In this paper, we considered four - two table (Konchanka white winter) wine (Ohrid white, Ohrid black). We tried, according ampelographic description certain characteristics reproductive system, determine their origin. According phenotypic refer centers origin varieties, studied Konchanka White winter belong Eastern convarietas orientalis, subconvarietas antasiatica, black variety Black Sea Balkan convarietas. pontica, balcanica. Among examined properties from second group descriptors described detail proposals O.I.V. some codes (characteristics) there big difference between Also, detailed differentiation cytological pollen germination vitality, chromosomes mitosis meiosis, ploidy level, percentage fertilization (fecundation), self-fertilization (autogamy) cross-fertilization (xenogamy). The statistical processing ampelography data cluster program (SPSS) works on binary similarity dissimilarity measures form clear dendogram display.
