The goals of this investigation was to evaluate the rooting, budding and development of roots from different rootstock of grapevine, in field conditions. Ligneous cutting of rootstock '420 A', 'Golia', '5C', '8B', 'RR101-14', 'SO4', '99R', 'Kober 5BB', 'IAC 766', 'IAC 572', 'IAC 571-6', 'Ripária do Traviú' and 'Rupestris du Lot' were planted in soil, without previous preparation. The experimental design was done in randomized blocks, with five repetitions and twenty cutting per plot, planted at distances of 12 x 5cm. The cutting were planted in the beginning of July and removed in the end of September, to be examined. The rooting percentage varied from 79% of 'Ripária do Traviú' to 99% of 'RR 101-14'. Due to budding, the 'Ripária do Traviú' showed 47%; 'IAC 571-6', 'IAC 572', '420A', 'Rupestris du Lot', 'Kober', 'IAC 766', '8B', '5C' showed 76 to 89% and 'Golia', 'SO4', '99R' and 'RR 101-14' showed more than 90%. 'IAC 572' and 'IAC 571-6' showed the minor root number per cutting, but they showed the most developed roots, followed by '5C' and 'Rupestris du Lot'. 'Kober 5BB' and 'Ripária do Traviú' showed the least developed roots. The other varieties showed intermediate values. It was conclued that, among all rootstocks, 'Ripária do Traviú' presented the lowest indexes of rooting and budding of cutting under field's conditions.
