The mean genetic distance (GD) between the root stock and scion of budgrafted Hevea trees was significantly more in tapping panel dryness (TPD) affected (33%) than healthy (20%) trees. More number of healthy trees tended to have a closer GD while more number of TPD trees had a wider GD between their root stock and scion. Thus a greater GD between the root stock and scion was observed to be associated with TPD even if this may not be an absolute prerequisite for the incidence of the syndrome. Exploitation of optimum GD between root stock and scion may be useful for excellence in agronomic performance of budgrafted plants
