The objective of this work was to identify, through the Pearson correlation and path analysis, variables to characterize rootstocks suitable for the cultivation of the pear (Pyrus communis L.). In this experiment 49 pear specimens were used, planted in flowerbeds at the Phytotechny Department. The plants were evaluated at the time of growth, according to parameters described in the instructions of the Ministério da Agricultura, Pecuária e Abastecimento. According to the Pearson correlation, the variables VP, NRP, ETA and FCNPRCL stood out. In path analysis, the variable number of lenticels had a more positive effect on VP, NRP and FCNPRCL, variable branch of the industry had a more positive effect on ETA. Both variables were considered effective in the process of selection of rootstock together with the basic variables.
