Tairov Institute of Viticulture and Wine-making" popup.description2 The dynamic agroclimatic model of grapes productivity formation "VITIS VINIFERA - 2013" was developed and modeling of productivity formation of different grape varieties till 2050 according to scenarios of climate change A1B and A2 was made. The initial information was statistical data, terms of grape development phases, agroclimatic directories for Steppe and Forest-steppe zone of Ukraine. According to the results of the field experiment in 2012 and 2013 and literature sources, the parameters of the model were clarified and its adequacy was checked (the calculation error does not exceed 8-12%). On the example of varieties Rubin Tairovsky and Zagrey, that differ in maturity, biological characteristics and moisture requirements, the modeling of the formation of grape productivity in the steppe and forest-steppe zone for the period 1986-2005, which characterizes the climatic norm, and for 2011-2030 and 2031-2050 according to climate change scenarios A1B and A2 were presented. The dynamics of leaf surface area formation and biomass accumulation during the vegetation period was estimated, tendencies, regularities and peculiarities of photosynthetic potential formation, net photosynthesis productivity and final yield of varieties in the context of these climatic periods were established. By 2030, due to deteriorating humid conditions in the steppe zone, the yield of both varieties is expected to decrease, and by 2050 the yield will be closer to modern. In the forest-steppe zone, we can expect an increase in yields compared to modern conditions, with slightly more by 2030. It should be noted that in both climate change scenarios, higher yields are expected in varieties with less demanding of moisture. In the Forest-Steppe zone, according to the A1B scenario for 2030 and 2050, the yield is expected to be close to the passport data: for the varieties Zagrey (13.6, 12.7 t/ha) and Rubin Tairovsky (16.1, 16.4 t/ha), and in the Steppe zone the yield will not exceed 12 t/ha.
