Vitis Vinifera varieties are characterized by high productivity and organoleptic properties, which is appropriate for use in scientific researches and modeling. Mathematical modeling of variety productivity helps to predict the yield of existing vineyards and to select terroir for prospective plantations. The approbation of a descriptive index-based classification incorporated into integral indicator of grape productivity (IIGP) is presented in this paper. Factor included are climatic and soil-morphological and the area of study is the Black sea agroecological zone of viticulture for table intraspecific hybrids and varieties by NCRRIH&V and AZESV&W breeding. The studies were carried out on 13 varieties of the Anapa ampelographic collection, using the meteorological information on Anapa (2007-2018). In the mode following agroecological Parameters were used: the sum of active temperatures during the vegetation period, the absolute minimum temperature of the year and the number of days with minimum temperature below -1C in the period from April to October, the total precipitation, the exposition and the slope angle, position on the slope and soil type. The results of model testing were acceptable for 10 varieties, the model worked best for following varieties: Astanikskiy, Bely Ranniy, Kavkazskiy Ranniy, Larni Muskatny and Hrustyashchiy. Non-acceptable results are received for three varieties (Licodia, Muscat AZOS and Chernomor Anapa), and it means that model for them requires improvements. In case of evaluating the results of the model by frost grape resistance, the best result was observed for varieties with increased resistance to frost. The model is recommended to use for the selection of terroirs in the Black sea agroecological zone of viticulture and the effective use of varieties in the ampelocenoses.
