This new V. cinerea x V. riparia rootstock, which is unique to GRAD, is by some distance the toughest and most hardy cool-climate-adapted rootstock available in New Zealand.
The outstanding performance of the GRAD® 106-8 rootstock has proven it to be highly reliable, moderate-vigour, robust, and strongly drought-resistant. In addition, it has the advantage for New Zealand vineyards that, unlike the V. berlandieri x V. rupestris drought-resistant stocks, it is very well adapted to cool climate conditions.
The outstanding performance of GRAD® 44-53 rootstock since GRAD® introduced it to New Zealand, proves it is a highly reliable, moderate-vigour, robust, and strongly drought resistant cool-climate-adapted rootstock.
