Given the growth of vine orchards to new areas and need for diversification scion rootstock combinations in subtropical sites, selecting right can bring significant benefits scions. Thus, current study sought determine impact rootstocks 'IAC 572' Jales, 766 Campinas' '1103 Paulsen' on productive performance, vigor, quality 'BRS Vitória' grapevines grown under circumstances. The experimental design was a randomized block design, with three treatments (rootstocks), seven blocks, plants per plot, total 63 grapevines. Over summer seasons (2020, 2021, 2022), production vigor components (number clusters vine, productivity, pruning mass), physical-chemical properties berries berries, fresh mass, length, width soluble solids, pH, titratable acidity, maturity index, as well quantities bioactive chemicals (phenols, flavonoids, anthocyanins), were all assessed. had influence majority factors studied. results showed that increasing increased yield while decreasing quantity solids grapes. whereas grapes from grafted onto '1103P' exhibited higher amounts phenols, anthocyanins. Overall, cultivar demonstrated high quality. As result, extending cultivation locations emerges an effective solution meet growing demand seedless
