We set the task to find out through our researches if the Italian Riesling variety transplanted on clones of rootstocks Berlandieri x Riparia Kober 5BB clone 114, Berlandieri x Riparia SO4 clone 74, Berlandieri x Riparia Teleki clone 10 and Sasla x Berlandieri 41B clone 87 could provide us with better financial effects than Belandieri x Riparia Kober 5BB, which is dominant at the locality of Crvenka at the Vrsac vineyards and on which the Italian Riesling variety is transplanted. Changeable economic circumstances, put new obstacle in front of managers in their tendency to gain good business results. Managerial activities get more complex in business systems where primary production is organized, as well as processing. For this purpose certain economic and mathematical models were stated, solving which led to optimal structure of grape and wine production. All organizational and technological requirements were met and net income per production unit was taken as a criterion. Raw materials (the Italian Riesling grapes), grown on a standard rootstock and its clones were used to produce first-rate quality wines considering the outcome of the production and the sugar content. Clones were selected according to the research results and their extent. The research results enabled establishing competition of clones comparing them to the rootstock Kober 5 BB and among themselves as well and determined factors of the structure of production in business systems. Since the results obtained in primary production transfer to processing, competition of clones reflects on various categories of wine. Applying method of modelling enabled, taking all relevant factors into consideration, determination of such a structure of production that will provide the maximum net income with appropriate expenses of input.
