4.6 Change in rootstocks 1997 to 2014
Figure 7 lists rootstocks of grapevine plantings in the Murray Valley study area and shows the
proportion of plantings that are not on a rootstock (29% in 2014). Plantings not on a rootstock
are either on their own roots or have been top-worked on to the roots of the previous variety.
The proportion of plantings on a rootstock increased from 30% in 1997 to 71% in 2014. The
dominant rootstocks are Ramsey (33%), Schwarzmann (13%) and Paulsen 1103 (10% of plantings).
