    The tomato crop (Lycopersicum esculentum Mill.) production is affected by pests and diseases, mainly due to the attack of nematodes, those are responsable for the root galls (Meloidogyne sp.), for this reason the objective of this research was to promote the use of tomato grafts with wild Solanaceae. Two commercial hybrids Pietro and Syta were used, as those are in high demand by farmers in Central zone, those hybrids are grafted in palo bobo (Nicotiana glauca Graham.) as an inducer of resistance to nematodes under cover conditions, which produced according to genetic parameters of variety, this research was obtaining the best results in hybrid Pietro with 2000 g of earthworm humus. Tomato grafts had an height of 1.35 m. and the weight per bunch was 876.1 g, the number of fruits was higher at harvest time 2 (2nd bunch) with an average of 6.42 fruits. The fruits of tomato were categorized according to the market requirement Pietro proved to be better to Syta with 28 and 362 fruits of first and second respectively. The evaluated roots of the grafts were analyzed visually comparing with the index of affectation scale by presence of galls, in those obtaining as a result that the grafts are in the scale 0 which means absence of nematodes in the root. The organoleptic characteristics of the grafted tomato didn't have difference between the tomato without grafting and these are pleasant in flavor, color, texture and aroma for human consumption.
