I'm working with a college group looking for ways to modify the vigor of tomatoe plants using grafting on other Solanaceae rootstock. We would all be grateful to get some research results on this.
Dear Gilles, a colleague in Spain is working on tomato grafting and made a document which I am adding to this mail. His name is and e-mail is: Alfredo de Miguel Gómes ([email protected]).
Best regards
Gerhard
Tomato was grafted to The Devil Plant (Solanum capsicoides); kangaroo apple; tamarillo; tobacco, wild eggplant Solanum torvum (http://esciencecentral.org/journals/solanum-torvum-as-a-compatible-rootstock-in-interspecific-tomato-grafting-horticulture.1000103.php?aid=25186); eggplant (Black L, Wu D, Wang J, Kalb T, Abbass D, et al. (2003) Asian Vegetable Research & Development Center. AVRDC Publication 3: 551.) ; Solanum habrochaites (Venema JH, Dijk BE, Bax JM, van Hasselt PR, Elzenga JTM (2008) Environmental & Experimental Botany 63: 359-367.) and some others.
If you don know already try to search with people involved in tha COST action on Grafting http://www.cost.eu/COST_Actions/fa/Actions/FA1204
Prof Giuseppe Colla from Viterbo Italy is coordinating this action and is aware of most activities going on on the topic.
Quite a few tomato rootstock varieties have been released recently. Many are interspecific hybrids between tomato and other Solanum species.
They are commerically available. A list of about 60 tomato rootstock varieties is available from vegetablegrafting.org.

it is much easier to select vigorous resistant to pests and pathogens rootstock variety than to breed high-yield resistant tomato cultivar.
