The viticulture in highlands of Southern Brazil, as a new wine region, show some production risks. One of the main problems that may restrict production are phytosanitary problems, like downy mildew. This disease often occurs in Brazil, particularly in warm and humid climates. The use of resistant varieties could be an alternative to cultivation, helpful to decrease the pesticides level, reducing costs and increasing wine quality. The objective of this study was to characterize the viticultural performance of PIWI genotypes grown in highlands of Southern Brazil. The experiment was conducted at a commercial winery (28°13S, 50°04'W, altitude 1,100m), the vineyard was planted in 2016 and the evaluations occurred in 2018 vintage. The evaluated varieties were Regent, Baron, Prior and Calandro. The phenological stages evaluated were bud break, flowering, veraison and maturity. At harvest were evaluated yield and technological maturity. The average date of bud break was September 3, the average date of flowering was October 19, the average date of veraison was December 21 and the average date of maturity was February 25. The variety Calandro presented the shortest cycle, with 149 days; the growth cycle from the others presented 183 days on average. The varieties Calandro and Regent presented the highest yields above 6 ton/ha. Even in a climate condition more favorable to downy mildew, all PIWI varieties evaluated presented a reduction in disease development with a considerable level of resistance and produced grapes with attributes suitable for production of high quality wines.
