Summary: Researches in viticulture and enology, has included problems of inventarisation and selecting existing cultivars, ampelotechnic, agrotechnic and introduction of clon matherial with the purpose of viticultur and enology improvment. This has been the way of including Croatia in international project with the purpose of scientific and relevant elaboration of major genotyps in Croatia with equal participation in international system of exchange data. Thus making a significant scientific contribution of completing genoplasmatic data for grapevine. Obtaining a solid base for receiving new cultivars by conventional breeding methods and cell - culture technics. Research results are basis for progress in viticulture and enology. Detail research of physical and chemical composition, sensory evaluation of wines produced from selected cultivars,with accent on hiperoxidation, someenological clarificators and treatments on wine quality, will be performed. It is congruently with modern trend of production socalled ecological wines. In the wines of chosen cultivars a detail researches of chemical composition with special regard to aromatic profil was performed. Enquiaris werw made regarded to effect of hiperoxidation of must on the quality of white wine. New researches are going with malolactic bacteria on the quality of red wines. The composition of volatil components (alcohols, esters) and bounded acids (malic, lactic) in natural and controled fermentation are conducted.

Keywords: Vitis vinifera L., genetic resurces, ampelographic caracteristics, screening, clonal selection tissue, electrophoresis, hyperoxidation of must, volatile components, sensory evaluation

Research goals: On the request of FAO in 1979., a iniciative was made forpreserving gen fundus of plant species and cultivars in theworld.The organisation of gen bank for vines took OIV Paris.The Faculty of agriculture, Departments of viticulture andenology was registrated in 1989. under the sign "JUG - 05 - ZGB". According to our requirement,this registration was changed in 1994 to CRO 01.Work on inventarisation of autochthon and domestic cultivarsVitis vinifera L. will be continued, as well as investigation on modern technology of reproduction virus-freematherial, interaction of stock and scion. Wine researchec: establishing the relevant aroma composition and organic acids content in relation to some tehnological process (hiperoxidation) and the usage of enological means (enzyme, malolactic bacteria kulture).
