The southern Brazil is the largest grape producer region in the country. It is characterized by the production of labrusca grapes due to the difficulty of growing V. vinifera. This can be explained by the high occurrence of fungal diseases, especially downy mildew, which is favored by its environmental conditions (high temperatures, relative humidity and rainfall). PIWI (Pilzwiderstandsfahige) are a group of wine grape varieties similar to V. vinifera but with resistance to downy and powdery mildew. These varieties open the possibility of reducing production cost and the use of agrochemicals for grape growing in Brazil. In order to achieve this objective, studies related to phenological, productive and qualitative characteristics are necessary. A PIWI variety trial was established in 2015, in the city of Videira, Santa Catarina State, Brazil, with five white varieties. The vineyard were trained in VSP and pruned in double cordon. The studied varieties were Felicia, Calardis Blanc, Helios, Bronner and Aromera, grafted on Paulsen 1103. The variables evaluated were phenology, incidence of downy mildew, yield, number of clusters, average cluster weight, total soluble solids, pH and total titratable acidity. In terms of productivity, the outstanding varieties were Felicia and Calardis Blanc, with yields above the traditional Vitis vinifera varieties. Felicia was the earliest variety and produced the heaviest clusters. Calardis Blanc presented the highest number of clusters and Aromera was the latest variety. All varieties presented high resistance to downy mildew compared to Vitis vinifera, with Felicia being the less resistant. Soluble solids contents, pH and acidity were adequate in all varieties. In general, all tested varieties presented potential for the studied region. MenosThe southern Brazil is the largest grape producer region in the country.
