Reportedly that works - Ficus glomerata aka racemosa can successfully work as a nematode-resistant rootstock for Ficus carica. I recently got a plant of what is supposed to be Ficus glomerata, and I am actively multiplying it by cuttings so I can try grafting on good varieties of edible figs.
Other Ficus species I'm currently testing as hopefully nematode-resistant fig rootstocks are Ficus palmata, Ficus pumila, and the one from ECHO in Fort Myers, which Crafton Cliff says is Ficus sycomorus.
Species I've heard can work as fig rootstocks which I havn''t acquired yet are Ficus opposita, Ficus septica, Ficus ulmifolia, and Ficus pseudopalma.
