Due to incomplete data of the trials, it was insufficient for scientific publication. Rootstocks are ranked according to scion-rootstock performance (Tables 2 and 3). Trends were compared with results obtained in other trials.

Data available. See Tables 2 and 3.

Trial terminated in 2002 due to: (i) no commercial interest in the cultivar; and (ii) no data available in 2001, because the producer already harvested grapes before the agreed harvest date. No or insufficient data in 5 out of 10 years, due to: (i) in two seasons, the grapes had already been harvested by the farm before the agreed harvest date; (ii) in two seasons, due to high incidence of downy mildew; and (iii) in one season due to high bud mite infestation. Due to the incomplete data of the trials, it was insufficient for scientific publication, but trends were compared with results obtained from other trials. This emphasis the challenges of executing trials on commercial farms, where the required standard cultivation practices have not been correctly applied in the trial sites.
