I've got a handful of tomato grafts growing this year on Black Beauty Eggplant (Solanum melongena) and Gbogname (S. Macrocarpon). While there are several potentially confounding factors (timing, soil, graft quality), performance on both has been extremely poor. Flavor doesn't seem to be adversely affected, but the plants on both are stunted and the fruits are small and scarce. It hasn't been a very encouraging experiment. By contrast, the couple dozen grafts I have on the commercial rootstock Multifort (S. lycopersicum × S. habrochaites) are generally doing better than the same varieties on their own roots.
