Pepper cv. 'Andalus' and 'Delicacy' grafted on seven wild eggplant species and 13 eggplant lines showed retarded growth. At 15-45 day after grafting, the stunted plants gradually developed purplish vein, leaf chlorosis and defoliation, followed by plant death in all graft combinations. Graft incompatibility was confirmed between pepper scions and eggplant rootstocks in this study.
