Abstract  Five Prunus rootstocks-GF677 (P. persica ×  P. amygdalus), Antafuel (P. amygdalus ×  P. persica), St. Julien 655/2 (P. insititia ×  P. domestica), Peach Seedling (P. persica), and Gisela 5 (P. cerasus ×  P. canescens)-were evaluated for their susceptibility to Agrobacterium tumefaciens. The results showed that no rootstock tested was immune. The St. Julien 655/2 rootstock was the most resistant of all tested, whereas no significant difference was observed between the other rootstocks. The level of susceptibility did not vary according to the strains used.
