Based on the hypothesis that resistance to VSD varies in cocoa and that rootstocks can influence VSD resistance of scions through grafting, the present research aimed to assess the VSD-incidence on cocoa scions of Sulawesi local clones in the field after grafting onto rootstocks from cocoa resistant genotype trees, to evaluate the effect on VSD-incidence in the scions on various cocoa rootstocks and to study whether a clone with proved resistance to VSD will result in an equivalent resistance if it is used as a rootstock. |
