In 2002, theyield on Börner rootstock was 0.8 kg/vine higher in comparison with SO4 cl. 31 (P ≤ 0.05). In spite of the dry stress conditions in 2003, the yield was higher in all rootstocksthan the yields in 2002.Comparing both experimental years, the highest yield difference for the same rootstock occurred with rootstock 196/17 Cl, and the lowest one with rootstock 41B/72. The influence of rootstocks on the yield has been reported by many studies (Williams & Smith 1991; Bica et al. 2000; Ollat et al. 2003).
