Conteúdo: 	The Santa Catarina State is the second largest producer of wine in Brazil. In this place, two producer poles stand out, the highlands (above 900m) that exclusively produce European varieties for wine production and the Midwest region where American varieties (like labrusca types) for wine and juice are produced in large part. The occurrence of fungal diseases, caused by high precipitation rates, is the main obstacle to viticulture in Santa Catarina. In this sense, the cultivation of varieties that combine disease resistance and wine quality (PIWI) can be an alternative to improve the quality of wines produced, reduce costs and reduce the environmental impact of viticulture. To perform this work, a collaboration project was developed between Santa Catarina State Agricultural Research and Rural Extension Agency (Brazil), Santa Catarina Federal University (Brazil), Julius Kuhn. Institute (Germany) and Edmund Mach Foundation (Italy) in order to test the adaptation of resistant varieties in different wine producing areas of Santa Catarina State. The objective of this work was to evaluate the performance of three PIWI varieties in two regions in vintage 2018. The evaluated varieties were Regent, Prior and Calandro. The vineyards were settled in the highlands (São Joaquim, 28°13'S and 50°04'W, altitude 1100m) and in the Midwest (Videira, 27°01'S and 51°08'W, altitude 830m). The date of occurrence of main phenological stages (budbreak, full bloom, veraison and maturity), productive indexes (number of clusters, fertility index and productivity), clusters characteristics (cluster compactness, weight, diameter and number of berries) and qualitative indexes of the grapes (soluble solids, total acidity and pH). Budbreak occurred on average 3 days earlier at 1100 m and Regent was the earliest variety. The development of plants is slower when they are grown at higher altitude. Full bloom occurred on average 17 days later at 1100 m, veraison occurred on average 17 days later at 1100 m and maturity occurred on average 37 days later at 1100 m altitude. At 830 m altitude, the average cycle length was 134 days, while at 1100 m altitude the average cycle length was 174 days. The number of clusters was higher at 830 m, but there was no statistical difference for the other productive indexes. Prior was the variety that achieved the lowest productivity in both locations. Prior and Calandro have the most compact clusters, as well as berries of larger diameter and greater weight. In both evaluated sites, it was possible to produce grapes with adequate quality for wine production, however in the vineyard at 1100 m altitude the highest soluble solids contents, lower total acidity and pH were observed. Among the evaluated varieties, Regent stood out by the best maturation indexes and the high productivity. The compact clusters of Calandro make it very susceptible to damage caused by grape rot (common in areas of high precipitation such as Southern Brazil) and the low productivity of Prior seems to indicate difficulties in adapting to the environmental conditions of Southern Brazil.
