The objective of this work was to evaluate the vigour, flowering time, production and fruit quality of peaches from the cultivars ‘Maciel’ and ‘Chimarrita’ grafted on rootstocks ’Aldrighi’, ‘Capdeboscq’, ‘Flordaguard’, ‘Nemaguard’, ‘Okinawa’ and ‘Umezeiro’. The experiment was conducted at the Embrapa Uva e Vinho, in Bento Gonçalves/RS. Vegetative and productive variables were analyzed in the field, and the physical-chemical analysis of the fruits were held at the Faculdade de Agronomia Eliseu Maciel (Universidade Federal de Pelotas – UFPel, Pelotas, Rio Grande do Sul, Brazil), during the 2008 and 2009 seasons. According to the results, it was concluded that the Maciel and Chimarrita cultivars grafted on ‘Umezeiro’ are less vigorous, and showed symptoms of incompatibility. The flowering of the peach trees from cultivars Maciel and Chimarrita is influenced by the rootstocks, which may delay or anticipate the beginning and the full bloom in up to eleven days. The estimated production and productivity per hectare of the ‘Maciel’ trees are greater when grafted on ‘Flordaguard’, and smaller when grafted on ‘Umezeiro’.
