Previous studies indicate a significant dependence between the quantity and the quality of grape yields (sugar and acidity) in some years and weather and climatic conditions. The established trends of global and regional climate change require immediate studies of the expected variability in the grape harvests quality in some natural zones of Ukraine by 2050. The aim of the project is to study the impact of weather and climatic conditions on the quality of grape harvests in natural zones of Ukraine under climate change by 2050. The research will be aimed at establishing agroclimatic indicators, that determine the formation of grape harvest quality, their dynamics and trends under climate change in different natural zones of Ukraine, and dynamics and trends of grape harvest quality until 2050.

 The object of research is the resources of light, heat and moisture, their spatial distribution for grape varieties Muscat Odessa, Sukholimansky white and Odessa black in the Steppe zone of Ukraine using the example of Zaporizhia, Mykolaiv, Odessa and Kherson regions. The purpose of the research was to investigate the patterns and features of spatial distribution and interannual variability of agroclimatic indicators that affect the formation of the quality of the grape harvest. Research methods - methods of agroclimatic calculations and generalizations, statistical methods and mapping methods were used. Features were identified in the timing of the beginning of the filling of berries - technical ripeness and duration of the period in grape varieties Muscat Odessa, Sukholimansky white and Odessa black in the Steppe zone of Ukraine. For the first time, for the Steppe Zone of Ukraine, using the example of Zaporizhia, Mykolaiv, Odessa and Kherson regions, an analysis of the spatial distribution and temporal variability of such indicators of light, heat and moisture resources as the duration of sunlight, the sum of total and photosynthetically active radiation, the sums of average daily, daytime and nighttime temperatures, the amount of precipitation, the sums of water vapor saturation deficits in the air, the reserves of productive moisture in the meter layer of soil at the beginning and end of a certain period, the actual moisture consumption and moisture demand (potential and actual evapotranspiration), moisture availability and hydrothermal coefficient for the period from the filling of berries to technical ripeness was carried out for the grape varieties Muscat Odessa, Sukholimansky white and Odessa black. Mapping of light, heat and moisture resource indicators (a total of 16 agroclimatic indicators) was carried out, which provides a visual representation of the features of their spatial distribution for the grape varieties Muscat Odessa, Sukholymansky White and O
