Studies are necessary to understand the productive behavior of grape cultivars on different rootstocks, in regions where their cultivation is potentially favorable. Thus, the objective of this work was to evaluate the influence of the combination of canopy x rootstocks on production, fruit quality, thermal requirement and maturation curve of table grape cultivars, in brazilian Cerrado conditions. A randomized block design was adopted, with five repetitions. The studied combinations were composed by the rootstocks IAC 766 ‘Campinas’ and IAC 572 ‘Jales’ under the cultivars ‘BRS Vitória’, ‘BRS Núbia’, ‘BRS Isis’ and ‘Niágara rosada’. Each cultivar was evaluated in isolation according to the two rootstocks. The cultivar ‘BRS Vitória’ showed higher productivity on the rootstock IAC 766 and greater development of bunches and berries on the IAC 572. This cultivar presented a thermal requirement of 1419 Degrees-Day from pruning until harvest. The ‘BRS Núbia’ cultivar showed higher productivity on the IAC 572 rootstock. The thermal requirement for ‘BRS Núbia’ to complete its cycle was 1725 Degrees-Day. The cultivar ‘‘BRS Isis’’ on the rootstock IAC 572 showed higher values of productivity, yield and number of bunches per plant. The IAC 766 ‘BRS Isis’ rootstock showed a thermal requirement of 1958 Degrees-Day. For IAC 572, 2079 Degrees-Day were required. The rootstocks evaluated did not influence the productive and physical-chemical characteristics of the cultivar ‘Niágara rosada’, the thermal requirement was 1622 Degrees-Day, for both rootstocks.
